HomeWeb Front-endHTML Tutorialcss float 浮动属性使用方法和实例讲解

Css的float浮动属性,用于设置标签对象(如:

标签盒子、标签、标签、标签等html标签)的浮动布局,浮动也就是我们所说标签对象浮动居左靠左(float:left)和浮动居右靠右(float:right)。

float是什么意思?float是浮动,翻译成中文也是浮动意思。进入对应css手册中float手册了解float基本信息。

float的作用:通过css定义float(浮动)让div样式层块,向左或向右(靠)浮动。

 

一、float语法 

<code class="language-css">float : none | left |right</code>

参数值: 
none :  对象不浮动
left :  对象浮在左边
right :  对象浮在右边

接下来我们来通过一实例讲解float使用技巧。

 

二、float应用与用法

Float浮动用于设置对象靠左与靠右浮动样式,可以实现我们所需要的让DIV、SPAN等标签居左居右浮动。

简单使用语法

<code class="language-css">div{float:left} /* css注释:设置div对象浮动靠左(left) */ 

div{float:right} /* css注释:设置div对象浮动靠右(right) */ </code>

 

三、css float浮动案例

创建一个水平菜单

使用浮动来创建水平菜单的超链接列表。

<code class="language-html">


<style>
ul{float:left;width:100%;padding:0;margin:0;list-style-type:none;}
a{float:left;width:6em;text-decoration:none;color:white;background-color:purple;padding:0.2em 0.6em;border-right:1px solid white;
}
a:hover {background-color:#ff3300;}
li {display:inline;}
</style>


<ul>
<li><a href="#">Link one</a></li>
<li><a href="#">Link two</a></li>
<li><a href="#">Link three</a></li>
<li><a href="#">Link four</a></li>
</ul>

</code>

四、css浮动总结 

我们要区别与文字内容靠左( text-align:left)靠右( text-align:right)样式,浮动只针对html标签设置靠左靠右浮动样式。float浮动样式没有靠中(浮动居中)的样式,如果需要让标签对象居中我们在css布局居中相关文字给大家详细讲解介绍(css margin)。这里记住浮动靠右使用float:right,浮动靠左使用float:left样式即可。
