我是编码新手，在使页面在所有浏览器上正确显示时遇到问题。现在它可以完美地与 IE 配合使用，但是当我在 Firefox 或 Chrome 中打开时会丢失格式。

这是我正在使用的代码的摘录：

 <style type="text/css">

#headerIMG {
    padding:0;
    margin:0;
    margin-bottom:15px;
    width:100%;
    }
label {
    padding-right:10px;
    text-align:left;
    {
table   {
    width: 580px;
    margin: 0 auto;
    text-align: center;
    align: center;
    }

.centerspacer {
    width:50%;
    }
tr  {
    width: 580px;
    margin: 0 px;
    }

td {
    padding:5px;
    }
.center {
    text-align:center;
    }
.button {
    float:none;
    display:block;
    margin: 10px auto;
    text-align:center;
    }

form    {
    width: 580px;
    margin: 0 auto;
    }
.rectbcontent {
    width: 580px;
    margin: 0 auto;
    text-align:center;
    }
table.tbody {
    width: 580px;
    margin: 0 auto;
    }
</style>

centerspacer要使表格居中，请从标记中删除这些单元格，并仅使用

table {
    margin-left: auto;
    margin-right: auto;
}

此外，您的 css 声明中存在语法错误label，这将导致以下任何样式崩溃。检查浏览器的错误控制台！

对于相对定位的元素：

margin:0 auto;

对于其他一切：
