使用缩写可以帮助减少你CSS文件的大小,更加容易阅读。css缩写的主要规则如下:
颜色(color)
16进制的色彩值,如果每两位的值相同,可以缩写一半,例如:
#000000可以缩写为#000;#336699可以缩写为#369;
边框(border)
边框的属性如下:
border-width:1px;
border-style:solid;
border-color:#000;
可以缩写为一句:border:1px solid #000;
语法是border:width style color;

CSS is important. And it is being used more and more often. Cascading Style Sheets offer many advantages you don’t have in table-layouts - and first of all a strict separation between layout, or design of the page, and the information, presented on the page. Thus the design of pages can be easily changed, just replacing a css-file with another one. Isn’t it great? Well, actualy, it is.Over the last few years web-developers have written many articles about CSS and developed many useful techniques, which can save you a lot of time - of course, if you are able to find them in time. Below you’ll find a list of techniques we , as web-architects, really couldn’t live without. They are essential and they indeed make our life easier. Let’s take a look at 53 CSS-based techniques you should always have ready to hand if you develop web-sites.

实现方法很简单在CSS中添加以下代码,然后修改下面的图片路径,随便找个乱七八糟的图放上去,就OK. 另存起来还是有点头疼的,要看源代码才行。实现这个方法同样用到了CSS的expression功能。什么是expression请参见http://blog.nzye.com/read.php/205.h...这里。
img {
filter:expression(
this.不能去掉 ? "" :
(
(!this.complete) ? "" :
this.runtimeStyle.filter = ("progid:DXImageTransform.Microsoft.AlphaImageLoader(src='" + this.src + "')") +
String(this.不能去掉 = true).substr(0, 0) +
(this.src = "http://blog.nzye.com/images/clear.gif").substr(0, 0)
)
);
}
filter:expression(
this.不能去掉 ? "" :
(
(!this.complete) ? "" :
this.runtimeStyle.filter = ("progid:DXImageTransform.Microsoft.AlphaImageLoader(src='" + this.src + "')") +
String(this.不能去掉 = true).substr(0, 0) +
(this.src = "http://blog.nzye.com/images/clear.gif").substr(0, 0)
)
);
}
