[overflow] CSS text-overflow: ellipsis; not working?

I don't know why this simple CSS isn't working...

.app a {_x000D_
  height: 18px;_x000D_
  width: 140px;_x000D_
  padding: 0;_x000D_
  overflow: hidden;_x000D_
  position: relative;_x000D_
  margin: 0 5px 0 5px;_x000D_
  text-align: center;_x000D_
  text-decoration: none;_x000D_
  text-overflow: ellipsis;_x000D_
  white-space: nowrap;_x000D_
  color: #000;_x000D_
}

<div class="app">_x000D_
  <a href="">Test Test Test Test Test Test</a>_x000D_
</div>

Should cut off around the 4th "Test"

Also make sure word-wrap is set to normal for IE10 and below.

The standards referenced below define this property's behavior as being dependent on the setting of the "text-wrap" property. However, wordWrap settings are always effective in Windows Internet Explorer because Internet Explorer does not support the "text-wrap" property.

Hence in my case, word-wrap was set to break-word (inherited or by default?) causing text-overflow to work in FF and Chrome, but not in IE.

ms info on word-wrap property

You just add one line css:

.app a {
   display: inline-block;
}

I had to make some long descriptions ellipse(take only one lane) while being responsive, so my solution was to let the text wrap(instead of white-space: nowrap) and instead of fixed width I added fixed height:

span {_x000D_
  display: inline-block;_x000D_
  line-height: 1rem;_x000D_
  height: 1rem;_x000D_
  overflow: hidden;_x000D_
  // OPTIONAL LINES_x000D_
  width: 75%;_x000D_
  background: green;_x000D_
  //  white-space: normal; default_x000D_
}

<span>_x000D_

</span>

MUST contain

  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;

MUST NOT contain

display: inline

SHOULD contain

position: sticky

I have been having this problem and I wanted a solution that could easily work with dynamic widths. The solution use css grid. This is how the code looks like:

// css 
.parent{
      display: grid; 
      grid-template-columns: auto 1fr;
}      
.dynamic-width-child{
      white-space: nowrap;
      text-overflow: ellipsis;
      overflow: hidden;
}
.fixed-width-child{
      white-space: nowrap;
}

.

// html
<div class="parent">
  <div class="dynamic-width-child">
    iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii asdfhlhlafh;lshd;flhsd;lhfaaaaaaaaaaaaaaaaaaaa
  </div>
  <div class="fixed-width-child">Why?-Zed</div>

I faced the same issue and it seems like none of the solution above works for Safari. For non-safari browser, this works just fine:

display: block; /* or in-line block according to your requirement */
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;

For Safari, this is the one that works for me. Note that the media query to check if the browser is Safari might change over time, so just tinker with the media query if it doesn't work for you. With line-clamp property, it would also be possible to have multiple lines in the web with ellipsis, see here.

// Media-query for Safari-only browser.
@media not all and (min-resolution: 0.001dpcm) {
  @media {
    -webkit-line-clamp: 1;
    -webkit-box-orient: vertical;
    display: -webkit-box;
    white-space: normal;
  }
}

You can also add float:left; inside this class #User_Apps_Content .DLD_App a

Add display: block; or display: inline-block; to your #User_Apps_Content .DLD_App a

Can't comment due to reputation, so I'm making another answer:

In this case you will also have to remove the generally suggested display: block; property from the element you set the text-overflow: ellipsis; on, or it will cut off without the ... at the end.

The accepted answer is awesome. However, you can still use % width and attain text-overflow: ellipsis. The solution is simple:

display: inline-block; /* for em, a, span, etc (inline by default) */
text-overflow: ellipsis;
width: calc (80%); /* The trick is here! */

It seems whenever you use calc, the final value is rendered in absolute pixels, which consequentially converts 80% to something like 800px for a 1000px-width container. Therefore, instead of using width: [YOUR PERCENT]%, use width: calc([YOUR PERCENT]%).

Include the four lines written after the info for ellipsis to work

.app a
{
 color: #fff;
 font: bold 15px/18px Arial;
 height: 18px;
 margin: 0 5px 0 5px;
 padding: 0;
 position: relative;
 text-align: center;
 text-decoration: none;
 width: 140px;

 /* 
 Note: The Below 4 Lines are necessary for ellipsis to work.
 */

 display: block;/* Change it as per your requirement. */
 overflow: hidden;
 text-overflow: ellipsis;
 white-space: nowrap;
}

anchor,span... tags are inline elements by default, In case of inline elements width property doesn't works. So you have to convert your element to either inline-block or block level elements

In bootstrap 4, you can add a .text-truncate class to truncate the text with an ellipsis.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" />_x000D_
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>_x000D_
_x000D_
<!-- Inline level -->_x000D_
<span class="d-inline-block text-truncate" style="max-width: 250px;">_x000D_
  The quick brown fox jumps over the lazy dog._x000D_
</span>

Write these in your css rule.

display: block; /* or in-line block according to your requirement */
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;

So if you reach this question because you're having trouble trying to get the ellipsis working inside a display: flex container, try adding min-width: 0 to the outmost container that's overflowing its parent even though you already set a overflow: hidden to it and see how that works for you.

More details and a working example on this codepen by aj-foster. Totally did the trick in my case.
