CSS text-overflow: ellipsis; not working?

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

display: inline-block; /* for inline elements e.g. span, strong, em etc */
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]%).

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.

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:

.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;
}

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

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;
}

Just add in the div containing that paragraph

white-space: nowrap 
width: 50px; 
overflow: hidden;
text-overflow: ellipsis; 
border: 1px solid #000000;

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

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

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 My Case the display: flex; was preventing it from working

<p> <icon/> text </p>

p {
  display: flex; // prevent it from working
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

<p> <icon/> <span> text </span> </p>

p {
  display: flex; // prevent it from working
}

span {
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

MUST contain

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

MUST NOT contain

display: inline

SHOULD contain

position: sticky

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>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>

<!-- Inline level -->
<span class="d-inline-block text-truncate" style="max-width: 250px;">
  The quick brown fox jumps over the lazy dog.
</span>

You can do it using this:

p {
    display: block;
    text-overflow: ellipsis;
    white-space: nowrap;
    overflow: hidden;
  }

Please also ensure, that the immediate enclosing element has a fixed width, and the span where you want to apply ellipsis , has a display:block

For me I wasn't setting it inside the inner div I was setting it in outer div so even though I had nowrap, overflow:hidden, and a set width it wasn't working. The code looked like:

<div className="outer">
  <ToolTip>
    <div className="inner"> long content needing to be cut
    </div>
  </ToolTip>
</div>

As stated in the other answers:

• The element's width must be constrained in px (pixels). Width in % (percentage) won't work.
• The element must have overflow:hidden and white-space:nowrap set.

But this can be bypassed using the -webkit-line-clamp property along with the text-overflow to achieve ellipsis that are not bound to fixed width.

--line-clamp: 1;
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-line-clamp: var(--line-clamp);
-webkit-box-orient: vertical;

Update the --line-clamp variable in the above snippet to use it for multi-line ellipsis.

In responsive cases set max-width to parent element.

.wrapper {
  background-color: teal;
  padding: 40px 160px;
}

.container {
  padding: 20px 10px;
  background-color: white
}

.overflow-parent {
  max-width: 100px;

}

.overflow-content {
  width: 100%;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

<div class="wrapper">
  <div class="container">
    <div class="overflow-parent">
      <div class="overflow-content" title="some looooooooooong ellipsed text">
        some looooooooooong ellipsed text
      </div>
    </div>
  </div>
</div>

Or even without max-width:

.wrapper {
  background-color: teal;
  padding: 40px 260px;
}

.container {
  padding: 20px 10px;
  background-color: white
}

.overflow-content {
  width: 100%;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

<div class="wrapper">
  <div class="container">
      <div class="overflow-content" title="some looooooooooong ellipsed text">
        some looooooooooong ellipsed text
      </div>
  </div>
</div>

You just add one line css:

.app a {
   display: inline-block;
}

None of the above solutions worked for me, particularly regarding the width. Since I can’t set a fixed width and need it to adapt based on the parent element, I used container queries with max-width: 100cqi;, which adjusts to 100% of the parent container width.

There’s no need to set a width on .container; if it’s within a grid, the grid defines the width automatically, making it fluid rather than fixed. My solution below ensures that clipped text won’t overflow the parent but will instead display an ellipsis as expected.

div.container {
  container: container / inline-size;

  width: min(10rem, 100%); /* demo only */
  outline: 2px dotted blue /* demo only */
}

div.app a {
    display: inline-block;
    text-overflow: ellipsis;
    max-width: 100cqi;
    white-space: nowrap;
    overflow: clip;

    background: red /* demo only */
}

<div class="container">
  <div class="app">
    <a href="#">Test1 Test2 Test3 Test4 Test5 Test6</a>
    <a href="#">Test1 Test2 Test3 Test4</a>
    <a href="#">Test1 Test2</a>
  </div>
</div>

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

If you're trying to add text ellipsis inside a flex element. Make sure either you pass width to the child element or simply add max-width: 0
