css 分类属性答应你划定如何以及在何处显示元素。

css分类(Classification)实例：

如何把元素显示为内联元素
本例演示如何把元素显示为内联元素。

<HTML>
<head>
<style type="text/css">
p {display: inline}
div {display: none}
</style>
</head>

<body>
<p>本例中的样式表把段落元素设置为内联元素。</p>

<p>而 div 元素不会显示出来！</p>

<div>div 元素的内容不会显示出来！</div>
</body>
</html>

如何把元素显示为块级元素
本例演示如何把元素显示为块级元素。

<html>
<head>
<style type="text/css">
span
{
display: block
}
</style>
</head>
<body>

<span>本例中的样式表把 span 元素设置为块级元素。</span>
<span>两个 span 元素之间产生了一个换行行为。</span>

</body>
</html>

float 属性的简朴应用
使图像浮动于一个段落的右侧。

<html>
<head>
<style type="text/css">
img
{
float:right
}
</style>
</head>

<body>
<p>在下面的段落中，我们添加了一个样式为 <b>float:right</b> 的图像。结果是这个图像会浮动到段落的右侧。</p>
<p>
<img src="/i/eg_cute.gif" />
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.

将带有边框和边界的图像浮动于段落的右侧

<style type="text/css">
img
{
float:right;
border:1px dotted black;
margin:0px 0px 15px 20px;
}
</style>
</head>

<body>
<p>在下面的段落中，图像会浮动到右侧，并且添加了点状的边框。我们还为图像添加了边距，这样就可以把文本推离图像：上和右外边距是 0px，下外边距是 15px，而图像左侧的外边距是 20px。</p>
<p>
<img src="/i/eg_cute.gif" />
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.

</p>
</body>

</html>

带标题的图像浮动于右侧
使带有标题的图像浮动于右侧

<head>
<style type="text/css">

{
float:right;
width:120px;
margin:0 0 15px 20px;
padding:15px;

This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
</p>

<p>
在上面的段落中，div 元素的宽度是 120 像素，它其中包含图像。div 元素浮动到右侧。我们向 div 元素添加了外边距，这样就可以把 div 推离文本。同时，我们还向 div 添加了边框和内边距。
</p>

在上面的段落中，文本的第一个字母包含在一个 span 元素中。这个 span 元素的宽度是当前字体尺寸的 0.7 倍。span 元素的字体尺寸是 400%，行高是 80%。span 中的字母字体是 "Algerian"
</p>
