flex 项目内的 CSS 省略号

Question

I have a layout based on flexbox. Two columns, one fixed size and the second need to take the rest space. In the grow column I have a string that I want it to be clipped.

In Chrome it works fine. But it doesn't work in Firefox and IE. I tried to fix it by giving the grow (flex item) inner element a width by using relative and absolute positions, but then I got a corrupt layout. The corruption is related that the element's height doesn't take in account to all its child elements.

Note: the inner element inside the flex grow item is built with several div tags.

Here is the jsFiddle .

 .cols { display: flex; } .flex--0 { flex: 0 0 auto; } .flex--1 { flex: 1 1 auto; } .absolute { position: absolute; } .relative { position: relative; } .width--100 { width: 100%; } .ellipsis { text-overflow: ellipsis; white-space: nowrap; overflow: hidden; } .border { border: 1px solid gray; }

 <h1>Ellipsis inside Flex item</h1> <h2>Working fine in Chrome Not working in FF and IE</h2> <div class="cols border"> <div class="flex--0 border padding--sm">Icon</div> <div class="flex--1 border padding--sm"> <div class="ellipsis">Icon lkdjasdoif dlkjasdfo;isd fasldf ;asofj as;doifja dflkas d;laiksjdf oaisjdf asldkfj a;slkfdj as;oifj as;ldkfj asldkfjowiejfa;wlkdfj as;lkdjf as;lkdfj a;osifj aw;lkefj asldkfj ;aolifj aw;oiefjasl;dkfj a;slkdfj aodfj aw;lfjk as;lkdfj a;oiwefjr</div> <div>Icon</div> <div>Icon</div> <div>Icon</div> </div> </div> <div>Second BLOCK</div> <h2>Trying to fix in FF and IE (Layout corrupts)</h2> <div class="cols border"> <div class="flex--0 border padding--sm">Icon</div> <div class="flex--1 relative border padding--sm"> <div class="absolute width--100"> <div class="ellipsis">Icon lkdjasdoif dlkjasdfo;isd fasldf ;asofj as;doifja dflkas d;laiksjdf oaisjdf asldkfj a;slkfdj as;oifj as;ldkfj asldkfjowiejfa;wlkdfj as;lkdjf as;lkdfj a;osifj aw;lkefj asldkfj ;aolifj aw;oiefjasl;dkfj a;slkdfj aodfj aw;lfjk as;lkdfj a;oiwefjr</div> <div>Icon</div> <div>Icon</div> <div>Icon</div> </div> </div> </div> <div>Second BLOCK</div>

You can add min-width: 0; to the flex item.

.flex--1 {
  flex: 1 1 auto;
  min-width: 0;
}

Or add overflow: hidden; to it.

.flex--1 {
  flex: 1 1 auto;
  overflow: hidden; /*or auto*/
}

Why?

4.5. Implied Minimum Size of Flex Items

To provide a more reasonable default minimum size for flex items, this specification introduces a new auto value as the initial value of the min-width and min-height properties defined in CSS 2.1.

Alternatively, you can wrap the content into a container.

.container {
  display: table;
  table-layout: fixed;
  width: 100%;
}
.ellipsis {
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
}
