Display of CSS 3: Detailed explanation of box type_html/css_WEB-ITnose

In CSS, use the display attribute to define the type of box. Generally speaking, box types are divided into two categories: inline and block. For example, div defaults to block and span defaults to Inline. The default presentation mode can be modified through display.
<!DOCTYPR><html><head> <meta http-equiv="content-type" content="text/html;charset=utf-8"/> <title>block and inline elements</title> <style type="text/css"> div { background:#aaff00; } span { background:#ffaa00; } </style></head><body> <div>div元素1</div> <div>div元素2</div> <span>span元素1</span> <span>span元素2</span></body></html> Default div and span representation: http://jsfiddle.net/Web_Code/pt0j3b6n/embedded/result/
Use dispaly to modify, respectively Add the following rules to the above div and span styles:
//div中添加display:inline;//span中添加display:block;
The effect is as shown: http://jsfiddle.net/Web_Code/pt0j3b6n/1/embedded/result/
Are these two the only values ??for display? That would be wrong. Different values ??of display show different box types.
1. Inline-block type : It belongs to the block box type, but has the characteristics of inline box type when displayed. The default alignment for side-by-side display is bottom alignment, which can be modified with vertical-align.
Use inline-block to create a horizontal menu
<html><head><style type="text/css">ul{ margin:0; padding:0;}li{ display:inline-block; width:100px; padding:10px 0; background-color:#00ccff; border:solid 1px #666666; text-align:center;}a{ color:#000000; text-decoration:none;}</style></head><body> <ul> <li><a href="http://www.ido321.com" target="_blank">菜單1</a></li> <li><a href="http://www.ido321.com" target="_blank">菜單2</a></li> <li><a href="http://www.ido321.com" target="_blank">菜單3</a></li> <li><a href="http://www.ido321.com" target="_blank">菜單4</a></li> </ul></body></html> Effect: http://jsfiddle.net/Web_Code/pt0j3b6n/2/embedded/result/
PS: There is a difference between inline-block and inline. The former still belongs to block, so it has height and width attributes, while the latter does not.
2. Inline-table type : It is a table-related type, supported by IE 8 and other main browsers. See below for more table-related types.
First, look at an example that does not use inline-table
<html><head><style type="text/css">table{border:solid 2px #00aaff;}td{border:solid 2px #ccff00;padding:5px;}</style></head><body>淡忘~淺思<table> <tr> <td>A</td><td>B</td><td>C</td><td>D</td> </tr> <tr> <td>E</td><td>F</td><td>G</td><td>H</td> </tr> <tr> <td>I</td><td>J</td><td>K</td><td>L</td> </tr></table>你好</body></html> The effect is like this: http://jsfiddle.net/Web_Code/pt0j3b6n/3 /embedded/result/
If you want to create the effect of text wrapping around a table, you can use inline-table and modify the table style
table{display:inline-table;border:solid 3px #00ffaa;} Text wrapping The effect comes out: http://jsfiddle.net/Web_Code/pt0j3b6n/4/embedded/result/
Summary of table related types
| 元素 | 所屬類型 | 說明 |
| table | table | 此元素會作為塊級表格來顯示，表格前后帶有換行符。 |
| tabel | inline-table | 此元素會作為內(nèi)聯(lián)表格來顯示，表格前后帶有換行符。 |
| tr | table-row | 此元素會作為一個表格行顯示 |
| td | table-cell | 此元素會作為一個表格單元格顯示 |
| th | table-cell | 此元素會作為一個表格單元格顯示 |
| tbody | table-row-group | 此元素會作為一個或多個行的分組來顯示 |
| thead | table-header-group | 此元素會作為一個或多個行的分組來顯示 |
| tfoot | table-footer-group | 此元素會作為一個或多個行的分組來顯示 |
| col | table-column | 此元素會作為一個單元格列顯示 |
| colgroup | table-column-group | 此元素會作為一個或多個列的分組來顯示 |
| caption | table-caption | 此元素會作為一個表格標(biāo)題顯示 |
3. list-item Type : This type can display multiple elements as a list, and add a list tag at the beginning of the element
Set all divs in the example to the list-item type, use list-style -type specifies the mark as a hollow circle
<html><head><style type="text/css">div{ display:list-item; list-style-type:circle; margin-left:20px;}</style></head><body> <div>div1</div> <div>div2</div> <div>div3</div> <div>div4</div></body></html>
Effect: http://jsfiddle.net/Web_Code/pt0j3b6n/5/embedded/result/
4. Run-in type and compact type : When the element is specified as run-in or compact type, if there is a block type element after the element, Run-in type elements will be included inside block type elements, while compact type elements are placed to the left of
block elements. These two attributes have not gained popularity. A demo about run-in: http://www.zhangxinxu.com/study/201203/css-run-in.html
5. none type : change the display value When specified as none, the element will not be displayed. PS: Unlike visibility:hidden, the element with display:none will not occupy the original space, but visibility will still occupy the original space.

To reduce the size of HTML files, you need to clean up redundant code, compress content, and optimize structure. 1. Delete unused tags, comments and extra blanks to reduce volume; 2. Move inline CSS and JavaScript to external files and merge multiple scripts or style blocks; 3. Simplify label syntax without affecting parsing, such as omitting optional closed tags or using short attributes; 4.
