换行不适用于浏览器，但可以在jsfiddle.net上工作

标签： html css forms

我试图使用css和html编写一个小而简单的表单。问题是换行符（更具体地说是<br>标签）对我的网页没有影响。当我在浏览器上加载页面时，每个输入和标签似乎都在同一行。但是当我在Jsfiddle.net上运行我的代码片段时，它的工作正常。我试过在样式标签中放置display：block，但没有效果。我也尝试将每个输入和标签元素放在一个单独的div中，也没有效果。我使用的是Chrome版本49.0。它也不适用于Firefox。

这是我的CSS和HTML代码

	letter-spacing:3px;
}
#container{
	max-width:100%;

<div id="container">

在您对代码源文件的评论中提供的链接中，没有<br />个标记出现。如果您需要在每个元素之后使用<br />标记，那么它应该可以正常工作。修订后的文件包含在下面。

  <form action="websitelista.txt" method="post" >
