Question

我有一个div

<div id="cpyright" class="copyright" >
</div>

.copyright {
    float: right;
    margin-right: -115px;
    margin-top: -20px;
}

此样式将在firefox浏览器中应用。但在镀铬中，div位置是中心。为什么会发生这种情况。任何帮助将不胜感激。

在必然情况下，不同浏览器中的不同定位是由于每个浏览器都有一些默认的CSS样式。例如身体的边缘。最佳做法是使用CSS Reset代码模板（Google for it）重置您的CSS。

这里是an example by Eric：

    content: '';
    content: none;
}

/* remember to define visible focus styles! 
:focus {
    outline: ?????;
} */

/* remember to highlight inserts somehow! */
ins {
    text-decoration: none;
}
del {
    text-decoration: line-through;
}

table {
    border-collapse: collapse;
    border-spacing: 0;
}

对于您的情况，您可能希望将div absolute放在bottom right角落。这是正确的方法。

.copyright {
    position: absolute;
    right: 0;
    bottom: 20px;
}

此外，您可以使用position:fixed;，因此即使用户向下滚动页面，div也会保留在该固定位置。
