I. float grammatical structure and small examples

1. Float syntax:

Float: none | left | right

2. Introduction of float parameter values:

Float:none-objects do not float

Float:left-the object floats on the left

Float:right-the object floats on the right

3. Instructions for using float values:

The value of the float property indicates whether and how the object floats.

When this attribute is not equal to none and causes the object to float, the object is treated as a block object (block-level), that is, the display attribute equals block. That is, the display property of the floating object is ignored.

5. Small example of float configuration:

. exp-a {float: left}

2. Small instance of float

Here CSS5 uses float to set two boxes, one on the left and the other on the right. In order to observe the effect of floating objects on the left and right, set the css width, CSS height and CSS frame respectively.

1. Complete HTML CSS code

Float attribute small instance CSS5

.exp {width:500px; border:1px solid # 333; padding:10px; overflow:hidden}

. exp-a {float:left; width:200px; height:100px; border:1px solid # F00}

. exp-b {float:right; width:260px; height:120px; border:1px solid # 00F}

Float instance CSS code explanation:

.exp {width:500px; border:1px solid # 333; padding:10px; overflow:hidden}

In order to observe the effect of the child float floating the small DIV object on the left and right in the .exp object, set a black border and 500px padding width to prevent the internal child from getting close to the parent DIV. Because the child in the .exp sets float, set overflow:hidden to let the .exp open.
