几个比较实用的CSS
1、filter:chroma(color:#FFFFFF); 让指定的背景色透明,例:
<table cellspacing = "0" cellpadding = "0" border = "1">
<tbody>
<tr align = "center" bgcolor = "#cccccc">
<td><img src = "http://www.si58.com/up/pin/s_2007-12-04-1196777365.jpg.jpg“></td>
<td> <img style = "FILTER: chroma(color:#ffffff)" src = "http://www.si58.com/up/pin/s_2007-12-04-1196777365.jpg.jpg"></td>
</tr>
<tr align = "center">
<td>未使用该滤镜</td>
<td>使用该滤镜</td>
</tr>
</tbody>
</table>
2、word-break:break-all; 强制换行
<table cellspacing = "0" cellpadding = "0" width = "100" border = "1" style = "WORD-BREAK: break-all">
<tbody>
<tr>
<td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
</tr>
</tbody>
</table>
3、writing-mode:tb-rl; 用于设置文本的书写方向,可以有两个取值:
lr-tb:表示左右-上下,
left right - top bottom tb-rl:表示上下-右左,
top bottom - right left 需要 IE 5.5+ 才支持,
例:
<style>
.clsHoriz { writing-mode: lr-tb }
</style>
<div style = "writing-mode:tb-rl">
第一组垂直文字<span class = "clsHoriz">第一组水平文字</span>
第二组水平文字<br/><span style = "writing-mode:lr-tb">第二组水平文字</span>
第三组竖直文字<span class = "clsHoriz">第三组水平文字</span>
</div>
4、background-color: transparent; transparent表示透明色,例:
<span style = "background-color: #CCCCCC; padding:20px;">
<textarea style = "background-color: transparent;">
背景透明的TextArea
5、border-collapse:collapse; 它会自动把相同的边框线合并,例:
<style>
.grid { border-collapse: collapse; }
.grid td { border: solid 1px #cccccc; }
.gridNoCollapse td { border: solid 1px #cccccc; }
</style>
不使用border-collapse:collapse;
<table border = "0" cellpadding = "4" cellspacing = "0" width = "200" class = "gridNoCollapse">
<tr>
<td> 1.1</td>
<td> 1.2</td>
</tr>
<tr>
<td> 2.1</td> <td> 2.2</td>
</tr>
</table>
使用border-collapse:collapse;
<table border = "0" cellpadding = "4" cellspacing = "0" width = "200" class = "grid">
<tr>
<td> 1.1</td>
<td> 1.2</td>
</tr>
<tr>
<td> 2.1</td>
<td> 2.2</td>
</tr>
</table>
6、两个表格并排
<table border="1" style="display:inline;">
<tr>
<td>表格1</td>
</tr>
</table>
<table border="1" style="display:inline;">
<tr>
<td>表格2</td>
</tr>
</table>
7、overflow: auto; 自适应表格的高,可以自动加滚动条。
8、font:12px/18px; 字体大小/行高,例: <td><p style="font:12px/18px;">这里的12px就表示字体大小,18px其实就等价于css中的line-height。</p></td>
鼠标移上图片发亮
<style type="text/css">
.opacityit img{ filter:progid:DXImageTransform.Microsoft.Alpha(opacity=40); -moz-opacity: 0.4; }
.opacityit:hover img{ filter:progid:DXImageTransform.Microsoft.Alpha(opacity=100); -moz-opacity: 1; }
</style>
<a href="http://cnn.com" class="opacityit"><img border="0" src="email.gif" /></a>
鼠标移上有亮边框
.borderit img{ border: 1px solid #ccc; }
.borderit:hover img{ border: 1px solid navy; }
.borderit:hover{ color: red; /* irrelevant definition to overcome IE bug */ }
</style>
<a href="http://cnn.com" class="borderit"><img border="0" src="email.gif" /></a>
