没有显示HTML Div边框 [英] HTML Div border not showing

问题描述

我试图在HTML中为div元素添加边框。以下是我的代码。

 ＃container-border {border-width：2px; border-color：red;}  

< div id = 容器边界> ...< / div>

边框不显示。我看了一个类似的问题（这里），但我无法弄清楚为什么边框不显示。有什么建议吗？

注意：这段代码是HTML页面的一部分。其他代码可根据要求提供 border-style 是 none 。您需要为边框设置不同的值。

#container -border {border-width：2px;边框颜色：红色; border-style：dashed;}

< div id = 容器边界> ...< / div>

I'm trying to add a border to a div element in HTML. Below is my code.

#container-border {
  border-width: 2px;
  border-color: red;
}

<div id="container-border">
  ...
</div>

For some reason, the border doesn't show up. I had a look on a similar question (here) but I couldn't figure out why the border doesn't show up. Any suggestions please?

Note: This snippet is a part of an HTML page. Additional code could be provided upon request

解决方案

The default value of border-style is none. You need to set a different value for a border to appear.

#container-border {
  border-width: 2px;
  border-color: red;
  border-style: dashed;
}

<div id="container-border">
  ...
</div>
