我在我网站的左侧边栏上有一个登录名。当用户登录时，边栏宽度不会与用户未登录时保持相同。
有没有办法保持宽度不变？

最佳答案
如果标记相同，您总是可以在 CSS 中为其添加固定宽度:
<div id="sidebar">
...
</div>
#sidebar { width: 200px; }
当然，这假设边栏本身的标记在登录和未登录时都是相同的。
...假设您使用非表格布局。您仍然可以在侧边栏单元格上设置固定宽度，但表格通常不应用于布局目的。
编辑:啊，还有代码。我建议您阅读 CSS(谷歌“CSS 教程”等)并从您的代码中删除所有样式属性。它今天的样子使它真的非常难读，而且不容易更改。
关于asp.net - 即使列更改也保持宽度。 (HTML)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3038907/
