Without further ado, let’s start with the basics.

Type of box

1. Basic type of box

In css, use display to define the type of box. Generally divided into block type and inline type.

For example, div belongs to block type and span belongs to inline type

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">        div{            background-color: yellow;        }        span        {            background-color: #000099;        }    </style></head><body>   <div>我是div</div>   <span>我是span</span>   <span>我也是span</span></body></html>

By running this code, we It can be clearly seen that the width of the block type occupies the entire browser, while the width of the inline element is equal to the width of its content

Each line is only allowed to accommodate one block element, but can accommodate multiple inline elements.

Next, we can change the div to block type through the display attribute, and change the span to inline attribute to see its running effect.

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">        div{            background-color: yellow;            display: inline;        }        span        {            background-color: #000099;            display: block;        }    </style></head><body>   <div>我是div</div>   <span>我是span</span>   <span>我也是span</span></body></html>

2.inline-block type

Inline-block is a type of block box. Set the display attribute of the element to inline-block. Its display is the same as setting

to inline, but the width and height attributes of the element can only act on the block element. .

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">        div{            background-color: yellow;            display:inline-block;            width: 100px;            height: 100px;        }    </style></head><body>   <div>我是div</div>   <div>我是div2</div></body></html>

3. inline-table type

Look at the following first

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">        table        {            width: 200px;            border: solid 1px red;            display: inline-table;            vertical-align: bottom;        }        td{            border: solid 1px red;        }    </style></head><body bo>   大家好   <table>       <tr>           <td>1</td>       </tr>       <tr>           <td>2</td>       </tr>   </table>   大家好</body></html>

The table belongs to the block type. If you want the text to be displayed side by side with the table, you need to set the display attribute of the table to inline-table. However, each browser

has different alignment methods for text and tables. Generally, you need to set the display attribute of the table to inline-table. Set its alignment.

4.list-item type

　You can display multiple elements as a list and add a list mark in front of them.

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">      div{          display: list-item;          list-style-type: decimal;          margin-left: 30px;      }    </style></head><body bo>   <div>list1</div>   <div>list2</div>   <div>list3</div>   <div>list4</div>   <div>list5</div></body></html>

5.none type

If the element is set to none, the element will not be displayed.

6.overflow attribute

　overflow is a display method used when the content in the box cannot be displayed.

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">      #div1{          width: 100px;          height: 100px;          border: solid 1px red;          overflow: hidden;      }      #div2{          margin-top: 10px;          width: 100px;          height: 100px;          border: solid 1px green;          overflow: scroll;      }    </style></head><body>   <div id="div1">测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试</div>   <div id="div2">测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试</div></body></html>

There are also two attributes, overflow-x and overflow-y, which can be set separately for the horizontal or vertical direction beyond the box. Display the content of the range

Set the display mode.

7.box-sizing attribute

　 The box-sizing attribute is a new box model attribute in CSS3.

Use width and height in css to set the width and height of elements, but you can use the box-siziing attribute to specify

Whether the width and height set with the width and height attributes include elements The inner padding area, and the width and height of the border.

The box-sizing attribute values are content-box and border-box. The content-box indicates that the width and height of the element do not include the internal padding area

and the width and height of the border. The border-box indicates that the width and height of the element include the width and height of the internal padding area and the border.

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title></title>    <style type="text/css">        div{            width: 300px;            height: 300px;            border: solid 30px red;            padding:30px ;        }        div#div1{          box-sizing: content-box;          -webkit-box-sizing: content-box;      }        div#div2{          box-sizing: border-box;          -webkit-box-sizing: border-box;      }    </style></head><body>   <div id="div1">测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试</div>   <div id="div2">测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试测试</div></body></html>
