CSS Question

Using ellipsis inside flex item

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

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>

Answer

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

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

jsFiddle

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;
}
