Question

我的css出现问题似乎没有被接受。我有3种不同类型的具有相同字符的样式。奇怪的是，当我应用<div class = "block halfleft">..</div>时，它会显示正确的样式，但<div class = "twoblock halfleft">似乎不起作用！是什么原因引起了这个？

CSS

#member {
        padding: 0;
}

#member .block {
        width: 960px;
        margin-bottom: 40px;
        padding-left:30px;
        height: 475px;
        float: left;
        text-align: left;   
    }   
#member .twoblock {
        width: 960px;
        margin-bottom: 0;
        padding-left:75px;
        padding-bottom: 75px;       
        height: 100%;
        float: left;
        text-align: left;   
    }
#member .threeblock {
        width: 960px;
        margin-bottom: 0;
        padding-left:75px;
        padding-bottom: 75px;       
        height: 500px;
        background-color: #fff;
        float: left;
        text-align: left;   
    }
#member .block.halfleft, #member .twoblock.halfleft, #member .threeblock.halfleft{
        width: 520px;   
        height: 240px;  
        float: left;
        padding-top: 25px;
    }
#member .block.halfright, #member .twoblock.halfright, #member .threeblock.halfright{
        width: 350px;
        height: 240px;
        float: left;
        padding-top: 55px;      

    }

你有一些填充问题！ 75px正在加倍.twoblock＆gt; .twoblock和其他几个案例。避免这种情况的简单方法是添加

box-sizing:border-box;

到你的所有定义，这意味着填充将包含在定义的宽度中，而不是添加到它。

具有相同字符的样式的总和在css中编码错误？
