常用的CSS RESET
什么是css reset?为什么要使用css reset呢?其原因很简单,因为不同的浏览器对选择器可能会有不同的默认值,如缩进的长度,padding的大小等.如果不加以处理,将会导致不同浏览器上页面表现得不一样,甚至混乱.所以需要css reset把所有的东西复位,统一一下.下面介绍几种常用的css reset.
首先是一种简单的方法,把全部元素的padding,margin,border置0.
* {
padding: 0;
margin: 0;
border: 0;
}
padding: 0;
margin: 0;
border: 0;
}
这是最简单,最安全的方法,但也最耗资源.所以不推荐使用。
接下来是Yahoo!的重设代码,Yahoo!的重置消除了关键HTML元素上的不一致,有选择地重设,相对前一种方法,消耗资源要小得多,也是最多人使用的方法之一。
