Distance between columns of the html table. Using the cellspacing attribute
We have already figured out with you that HTML tables have frameworkthough browsers don't show them by default. But that's not all, each table cell also has a border called cell border... But that's not all, using the special tag attributes
For change distance between cells (their boundaries) and from cells to frame tables in tag
To set internal padding from cell borders to their content needed in the tag
Note that browsers set small (two pixels) values \u200b\u200bfor cellspacing and cellpadding by default, so to remove spacing altogether, set the attributes to zero (0).
Example of borders, borders and padding of HTML tables
Cell 1.1 | Cell 1.2 | Cell 1.3 |
Cell 2.1 | Cell 2.2 | Cell 2.3 |
Cell 3.1 | Cell 3.2 | Cell 3.3 |
Table with only the border and cell borders set:
Cell 1.1 | Cell 1.2 | Cell 1.3 |
Cell 2.1 | Cell 2.2 | Cell 2.3 |
Cell 3.1 | Cell 3.2 | Cell 3.3 |
Result in the browser
Table with changed indents and distances:
Naturally, it is not necessary to draw the frame and borders of the cells in the table in order to change the padding and spacing between cells.
According to HTML syntax, browsers add cellspacing and cellpadding values \u200b\u200bto the dimensions of the table and its cells. For example, if you set the cell width to 100 pixels and cellpadding \u003d "10" - browsers add 20 pixels to the width (10 each on the left and right) and it becomes 120 pixels. In general, you will figure it out along the way.
Deviation from the topic or how to remove padding at the edges of the page
Initially, all browsers set small margins at the edges of HTML pages, which are often unnecessary, so now you will learn how to remove them. In general, this information should be placed at the beginning of the textbook, but there it would hardly be useful to you.
At one time the tag
there were four attributes that set the size of these margins for each side of the page: topmargin (top), rightmargin (right), bottommargin (bottom), and leftmargin (left). These attributes are now deprecated, so we will apply styles (CSS). So, there are several ways to change the spacing of the padding at the edges of the page, I will show you two, and you will learn about the third if you decide to learn CSS.Method one. B tag
specify the style attribute with the following values: style \u003d "margin: 0"\u003e ... - removes indents from all sides of the HTML page at once. style \u003d "margin: top right bottom left">... - adjusts the size of indents for each side clockwise. Typically, pixel dimensions are used, for example: style \u003d "margin: 5px 3px 4px 5px"\u003e ...The second and more convenient way. In the tag
Homework.
In this lesson, I will not describe everything in detail either - only general points. For completeness, see the result of the example.
- Create three tables, each with one row and three columns (s).
- Place the Header or "header" of the page in the first table (not to be confused with the "header" of the HTML document), in the second - the left and right menus, as well as the main content (content), in the third - Footer or the "footer" of the page.
- Let the width of the first and last column of each table be fixed.
- Important. Use a tag just to create four horizontal menu buttons in the "header" of the page. In other cases, let the images be in the background, and in the second cells of the tables, only colors are generally used, and in the first and last table it is # 99FF99.
- Let the page content text be aligned on both sides of the table cell and the title centered.
- As for the spacing between table cells, as well as cell indents, think for yourself where you need to completely remove them, and where to increase them.
The CSS specification gives unlimited possibilities for table design. By default, the table and table cells do not have visible borders and backgrounds, and cells within the table are not adjacent to each other.
The width of table cells is determined by the width of their contents, so the width of the table columns can be different. The height of all cells in a row is the same and is determined by the height of the tallest cell.
Formatting tables
1. Table borders border
The table and cells inside it are displayed in the browser without visible borders by default. Table borders set by the border property:
Table (border-collapse: collapse; / * remove empty spaces between cells * / border: 1px solid gray; / * set an outer border of 1px gray for the table * /)
Header cell borders each column are set for the th element:
Th (border: 1px solid gray;)
Cell borders table bodies are set for the td element:
Td (border: 1px solid gray;)
The width of the borders of adjacent cells is not doubled, so you can set borders for the entire table in the following way:
Th, td (border: 1px solid gray;)
The outer border of the table can be selected by giving it an increased width:
Table (border: 3px solid gray;)
Borders can be set partially:
/ * set a 3px gray outer border for the table * / table (border-top: 3px solid gray;) / * set a 1px gray border for the table body cell * / td (border-bottom: 1px solid gray;)
You can read more about the border property.
2. How to set the width and height of the table
Default table width and height is determined by the contents of its cells. If no width is specified, it will be equal to the width of the widest row (row).
Table and Column Width set using the width property. If table (width: 100%;) is specified for a table, then the width of the table will be equal to the width of the container block in which it is located.
The width of the table and columns is usually specified in px or%, for example:
Table (width: 600px;) th (width: 20%;) td: first-child (width: 30%;)
Table height not set. The height of the rows tables can be manipulated by adding top and bottom padding to elements
Th, td (padding: 10px 15px;)
3. How to set the background of the table
Default table background and the cells are transparent. If the page or block containing the table has a background, then it will shine through the table. If the background is set for both the table and the cells, then only the background of the cells will be visible in the places where the background of the table and cells overlap. The background for the table as a whole and its cells can be:
fill,
,
.
4. Table columns
The CSS table model is focused mainly on strings (rows) formed using a tag
using the tag
You can set the background for any number of columns;
using the table td: first-child, table td: last-child selector, you can style the first or last column of the table (excluding the first cell of the table header);
using the table selector td: nth-child (column selection rule), you can style any columns in the table.
You can read more about CSS selectors.
5. How to add a table title
You can add a title to the table using the tag

6. How to remove the gap between cell frames
By default, the borders of table cells are separated by a small space. If we set border-collapse: collapse for the table, then the gap will be removed. The property is inherited.
Syntax
Table (border-collapse: collapse;)
Figure: 3. An example of tables with merging and split cell borders
7. How to increase the spacing between cell borders
Using the border-spacing property, you can change the distance between cell borders. This property applies to the table as a whole. Inherited.
Syntax
Table (border-collapse: separate; border-spacing: 10px 20px;) table (border-collapse: separate; border-spacing: 10px;)
Figure: 4. An example of tables with increased gaps between cell frames
8. How to hide empty table cells
The empty-cells property hides or shows empty cells. Only affects cells that do not contain any content. If a background is specified for a cell, and table (border-collapse: collapse;) is specified for a table, then the cell will not be hidden. Inherited.
Company | Q1 | Q2 | Q3 |
---|---|---|---|
Microsoft | 20.3 | 30.5 | |
50.2 | 40.63 | 45.23 |
9. Layout table layout using the table-layout property
The layout of a table layout is determined by one of two approaches: fixed layout or automatic layout. Layout in this case means how the width of the table is distributed between the width of the cells. The property is not inherited.
Syntax
Table (table-layout: fixed;)
10. Best Table Layouts
1. Horizontal minimalism
Horizontal tables are tables in which text is read horizontally. Each entity is a separate line. You can style tables like this in a minimalist style by placing a two-pixel border under the th heading.
Employee | Salary | Bonus | Supervisor |
---|---|---|---|
Stephen C. Cox | $300 | $50 | Bob |
Josephin tan | $150 | - | Annie |
Joyce ming | $200 | $35 | Andy |
James A. Pentel | $175 | $25 | Annie |
With a large number of rows, this design of tables makes them difficult to read. To solve this problem, you can add a one pixel border under all td elements.
Td (border-bottom: 1px solid #ccc; color: # 669; padding: 9px 8px; transition: .3s linear;) / * rest of the code - as in the example above * /
Adding a: hover effect to the tr element makes tables that are minimalist in style easier to read. When you hover the mouse over a cell, the rest of the cells in the same row are selected at the same time, which simplifies the process of keeping track of information if tables have multiple columns.
Th (font-weight: normal; color: # 039; padding: 10px 15px;) td (color: # 669; border-top: 1px solid # e8edff; padding: 10px 15px;) tr: hover td (background: # e8edff ;)
2. Vertical minimalism
Although such tables are rarely used, vertically oriented tables are useful for categorizing or comparing descriptions of objects represented by a column. You can style them in a minimalist style by adding a space separating the columns.
Th (font-weight: normal; border-bottom: 2px solid # 6678b1; border-right: 30px solid #fff; border-left: 30px solid #fff; color: # 039; padding: 8px 2px;) td (border- right: 30px solid #fff; border-left: 30px solid #fff; color: # 669; padding: 12px 2px;)
3. "Box" style
The most reliable style for decorating tables of all types is the so-called "box" style. It is enough to choose a good color scheme and then set the background color for all cells. Remember to emphasize the difference between lines by setting borders as separators.
Th (font-size: 13px; font-weight: normal; background: # b9c9fe; border-top: 4px solid #aabcfe; border-bottom: 1px solid #fff; color: # 039; padding: 8px;) td (background : # e8edff; border-bottom: 1px solid #fff; color: # 669; border-top: 1px solid transparent; padding: 8px;) tr: hover td (background: #ccddff;)
The most difficult thing is to find the color scheme that will blend harmoniously with your site. If the site is loaded with graphics and design, then it will be quite difficult for you to use this style.
Table (font-family: "Lucida Sans Unicode", "Lucida Grande", Sans-Serif; font-size: 14px; max-width: 70%; width: 70%; text-align: center; border-collapse: collapse ; border-top: 7px solid # 9baff1; border-bottom: 7px solid # 9baff1;) th (font-size: 13px; font-weight: normal; background: # e8edff; border-right: 1px solid # 9baff1; border- left: 1px solid # 9baff1; color: # 039; padding: 8px;) td (background: # e8edff; border-right: 1px solid #aabcfe; border-left: 1px solid #aabcfe; color: # 669; padding: 8px ;)
4. Horizontal zebra
Zebra table looks pretty attractive and handy. The complementary background color can serve as a visual cue for people to read the table.
Th (font-weight: normal; color: # 039; padding: 10px 15px;) td (color: # 669; border-top: 1px solid # e8edff; padding: 10px 15px;) tr: nth-child (2n) ( background: # e8edff;)
5. Newspaper style
To achieve the so-called newspaper effect, you can apply borders to table elements and play with the cells inside. A light, minimal newspaper style might look like this: play with the color scheme, add borders, padding, different backgrounds, and a: hover effect on hovering over a line.
Table (border: 1px solid # 69c;) th (font-weight: normal; color: # 039; border-bottom: 1px dashed # 69c; padding: 12px 17px;) td (color: # 669; padding: 7px 17px; ) tr: hover td (background: #ccddff;)
Table (border: 1px solid # 69c;) th (font-weight: normal; color: # 039; padding: 10px;) td (color: # 669; border-top: 1px dashed #fff; padding: 10px; background: #ccddff;) tr: hover td (background: # 99bcff;)
Table (border: 1px solid # 6cf;) th (font-weight: normal; font-size: 13px; color: # 039; text-transform: uppercase; border-right: 1px solid # 0865c2; border-top: 1px solid # 0865c2; border-left: 1px solid # 0865c2; border-bottom: 1px solid #fff; padding: 20px;) td (color: # 669; border-right: 1px dashed # 6cf; padding: 10px 20px;)
6. Table background
If you're looking for a quick and unique way to style your table, choose an attractive image or photo related to the table's theme and set it as the background of the table.
Png ") 98% 86% no-repeat;) th (font-weight: normal; font-size: 14px; color: # 339; padding: 10px 12px; background: white;) td (color: # 669; border- top: 1px solid white; padding: 10px 12px; background: rgba (51, 51, 153, .2); transition: .3s;) tr: hover td (background: rgba (51, 51, 153, .1); )
Hello! So, now you are able to create elementary tables, consisting of as many rows and columns as you need. Not bad, not bad. Now let's talk about the design of these tables.
In the last lesson, tables were displayed without borders. And, you see, it looks so-so, you can't even call it a sign. To make table borders in HTML, add to the tag So let's create borders for the table. For example, for the one we already have:
Result in the browser: In turn, to remove the borders of the HTML table, or you can also say to make them invisible, you need the attribute border set value 0
... After these simple actions, the frame will be removed. The attribute allows you to create but not manage borders. It only allows you to change their thickness. Therefore, now we will talk about CSSwhose properties make it possible with bordercreate different borders, both inside each cell and outside, around the table as a whole. Let's take a look at how to apply CSS to create the outer and inner borders of a table.
Result in the browser: Now let's add borders for each cell. To do this, just add the styles:
Result in the browser: Agree that a border defined with CSS does not have the same appearance as you would like. Undoubtedly, from the point of view of aesthetics, there is work to do. On the browser page, you can see that by default it displays the borders of tables and cells separately. An example clearly demonstrates this. However, it is quite possible to get rid of such borders, which are called double, if we use the border-collapse CSS property. In practice, it looks like this: Table (border: solid 1px blue; border-collapse: collapse;) ... As a result, the distance between the cells is removed: The collapse value assigned to the border attribute removes double borders. As you can see, the result is a collapse of adjacent cell borders, as well as the cell borders and the outer border of the table. As for the latter, it can be removed altogether. And if there is a need to display it, you need to increase its width. Thus, we got rid of the separators in the table. In the next lesson, we'll talk about how you can set vertical and horizontal borders. Good luck to all! We have considered many methods of styling elements on the page such as text information, links, images, headings, but all this is not enough yet. In my articles, I often use HTML elements such as tables, because in most cases they are help organize important information and make it easier to present. In this article, I will introduce you to the intricacies of styling HTML tables, and you will learn new CSS properties designed to achieve these goals. The hypertext markup language HTML has provided us with a large number of opportunities to bind CSS styles to ten unique tags designed to work with tables, I suggest repeating them before further study: In this example, we: The result of our example: After the above example, you may have noticed that we have a gap between all the table cells. Let's look at how to remove the gap between table cells, or increase it. To set the distance between the borders of neighboring cells, you must use the CSS property - border-spacing. In this example, we: I draw your attention to the fact that if only one length value is specified in the border-spacing property, then it indicates the spacing, both horizontally and vertically, and if two length values \u200b\u200bare specified, then the first determines the horizontal distance, and the second vertical. The distance between the borders of adjacent cells can be specified in CSS units (px, cm, em, etc.). Negative values \u200b\u200bare not allowed. The result of our example: You can say: - so, we removed the spacing between the cells using the border-spacing property with a value of 0, but why do we now have the borders of the cells intersecting? Double borders are formed due to the fact that the lower border of one cell is added to the upper border of the cell that is below it, a similar situation occurs on the sides of the cells and this is logical from the point of view of displaying the table, but fortunately there is a way to tell the browser that we are we do not want to see such cheeky behavior of cell borders. To do this, you need to use the border-collapse CSS property. Oddly enough, using the border-collapse property with the collapse value is the best way to remove the gap between cells and not get double borders between them. Consider a comparison of border behavior when using the border-spacing property set to 0 and the border-collapse property set to collapse: In this example, we: The result of our example: Using CSS, you can set whether to display borders and backgrounds for empty cells in a table or not. The empty-cells property is responsible for this behavior, which by default, as you may have noticed from the previous examples, displays empty cells. Let's move on to an example: To understand how the empty-cells property works from this example is very simple, if it is set to hide, then empty cells and the background in them will be hidden, if set to show (by default), then they will be displayed. Let's take a look at another simple property for styling tables - caption-side, which sets the position of the table caption (above or below the table). By default, the caption-side property is set to top, which places the caption above the table. In order to place the title under the table, you need to use the property with the bottom value. Let's see an example of using this property: In this example, we have created two classesthat control the position of the table header. First grade ( .topCaption) puts the table title above it, we applied it to the first table and the second class ( .bottomCaption) places the table title below it, we applied it to the second table. Class .topCaption has a default caption-side property and was created for demonstration purposes. The result of our example: In most cases, when working with tables, you will need to adjust the alignment of the content within header and data cells. The text-align property is used for horizontal alignment similar to any text information. We discussed the use of this property for text earlier in the article "". To set the alignment for the content in the cells, you must use special keywords with the text-align property. Let's consider the application of the keywords of this property in the following example. In this example, we have created four classesthat set different horizontal alignment in cells and apply them in order to the table rows. The value in the cell matches the value of the text-align property The result of our example: In addition to horizontal alignment, you can also define vertical alignment in table cells using the vertical-align property. Please note that when working with table cells, only the following values \u200b\u200b* of this property are used: *
- The values \u200b\u200bsub, super, text-top, text-bottom, length and% applied to a table cell will behave as if using a baseline value. Let's consider an example of use: In this example, we have created four classesthat set different vertical alignment in cells and apply them in order to the table rows. The value in the cell matches the value of the vertical-align property that was applied to that row. CSS uses the browser's automatic table layout algorithm by default. In this case the column width is set by the widest non-breaking cell content... This algorithm can be slow in some cases, as the browser must read all the contents in the table before determining its final layout. To change the placement type of the table layout by the browser with automatic on the fixed, you must use the table-layout CSS property with the fixed value. In this case, the horizontal placement depends only on from the width of the table and the width of the columns, and not from the contents of the cells. The browser starts displaying the table immediately after the first row is received. As a consequence, the fixed algorithm allows you to create the layout of such a table faster than using the automatic version. When working with large tables, you can use a fixed algorithm to improve performance. Let's look at the application of this property with the following example: In this example, we: We have already partially touched upon the methods of styling the rows and columns of the table in the article "". In this article, we looked at using a group pseudo-class that allows you to alternate row styles in tables using values even (even) and odd (odd), or by elementary mathematical formula. Let's revisit the previous techniques and learn about new ways to style rows and columns in tables. Let's move on to examples. In this example, we: The result of our example: Let's move on to the next example, in which we'll look at the options for styling table rows. In this example, we: The result of our example: Figure: 153 Example of Styling Rows in Tables The following example shows how to apply corner rounding to table cells (property). In this example, we: The result of our example: The following example touches on the use of HTML elements In this example, we: The result of our example: Well, and the final example, which is quite difficult to understand and requires advanced knowledge in CSS, as it touches on future topics planned for detailed study within the framework of this course. In the previous example, we realized that the HTML element In this example, we: The result of our example: If at this stage of the study you do not understand the process of positioning elements, then do not be discouraged, this is a difficult topic to understand, which we also did not consider, but we will definitely consider it in the next article of the tutorial "Positioning elements in CSS". Complete the Practice Activity before moving on to the next topic: If you have any difficulty in completing the practice, you can always open the example in a separate window and inspect the page to see what CSS was used. 2016-2020 Denis Bolshakov, you can send your comments and suggestions on the work of the site to the [email protected]
