CSS Body width不适用于每个网页

时间：2014-02-24 13:52:47

标签： html css jsf

我对CSS比较陌生，我正在创建一个Web应用程序，其中包含许多我想要在所有网页中居中的网页。我创建了一个CSS样式表，我将宽度设置为60％，将text-align设置为居中。在索引页面上，文档处于居中状态，但是当我点击链接时，下一页始终是屏幕的整个宽度。

我附上了下面的一些代码;

感谢您的帮助...

body元素位于html元素内部，如果要设置任何元素的宽度百分比，则应首先定义它的父元素宽度。

html {
    padding:0;
    margin:0;
    width:100%; /* 100% of window with, so the body width of 60% will work as expected */
}

你必须使用position：relative或position：absolute command。
