我目前正在为我的网站编写标题，我有一个朋友正在帮助我。我们有两台非常不同的计算机（PC 和 Mac）并使用不同的浏览器来确保它是多平台的，并且我们发现标题不适合他的屏幕。所以我意识到只获得窗口宽度并将其除以四并使其成为按钮的大小会更容易。我该怎么做呢？

非常感谢！

编辑：这是我正在使用的：

    div.horizontal
{
    position: relative;
    width: 100%;
    height:45px;
}   

div.horizontal ul
{
list-style-type:none;
margin:0;
padding:0;
} 

div.horizontal li
{
float:left;
}

div.horizontal a
{
display:block;
background: -moz-linear-gradient(top,  rgba(255,255,255,0) 0%, rgba(255,255,255,0.10) 52%, rgba(255,255,255,0) 100%), url("../img/truefactzheader.png");
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,0)), color-stop(52%,rgba(255,255,255,0.10)), color-stop(100%,rgba(255,255,255,0))), url("../img/truefactzheader.png");

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00ffffff', endColorstr='#00ffffff',GradientType=0 );
width:25%;
height:35px;

好吧，假设您的标题元素是屏幕的 100% 宽度，并且您希望按钮的宽度相等，那么数学应该是 > 100 / 4 = 25%。您的每个按钮都应占据页眉宽度的 25%。

因此，在您的 CSS 中，您应该将它们定义如下：

#my_header {
    width: 100%;
    float: left;
}
    #my_header a.button {
        display: block;
        float: left;
        width: 25%;
        height: 30px
    }

请看这个jsFiddle 演示。

因此，您需要按如下方式更新您的代码（为清楚起见，我删除了特定于浏览器的属性：

div.horizontal {
    position: relative;
    width: 100%;
    height:45px;
}   

div.horizontal ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
} 
div.horizontal li {
    float: left;
    width: 25%;
}

div.horizontal a {
    display: block;
    background: linear-gradient(to bottom,  rgba(255,255,255,0) 0%,rgba(255,255,255,0.10) 52%,rgba(255,255,255,0) 100%), url("../img/truefactzheader.png");
    height:35px;
}
