在换行符时如何隐藏分隔符? [英] How to hide separator when at newline?

问题描述

我认为这是最容易用示例解释的情况.

I think this is easiest to explain with an example.

假设我在这样的网页上有一个列表:

Let's say I have a list on a webpage like this:

word one, word two, word three, word four, word five, word six

如果用户的屏幕分辨率较小，则列表可能最终像这样包装:

If the user has a small screen resolution, the list may end up wrapping like this:

word one, word two, word three, word four, word five, 
word six

如您所见，第一行末尾有一个逗号.我想更改它，以便在发生这种情况时将逗号隐藏起来.这意味着它看起来像这样:

As you can see, there is a comma at the end of the first line. I would like to change it so if something like this occurs, the comma is hidden. That means it would look like this:

word one, word two, word three, word four, word five
word six

是否可以使用CSS或Javascript做到这一点?

Is there a way to do this with CSS or Javascript?

感谢您的帮助.

推荐答案

是.只需让它们以负边距溢出，然后隐藏溢出即可.

Yes. Just let them overflow with negative margins, and hide the overflow.

div {
  border: 1px solid;
  overflow: hidden;
  animation: size 5s linear infinite alternate;
}
span {
  display: inline-block;
  margin-right: 10px;
}
span::before {
  content: ',';
  display: inline-block;
  width: 10px;
  margin-left: -10px;
}
@keyframes size {
  from { width: 750px; }
  to { width: 0; }
}

<div>
  <span>word one</span>
  <span>word two</span>
  <span>word three</span>
  <span>word four</span>
  <span>word five</span>
  <span>word six</span>
</div>
