text-overflow: ellipsis not working

Question

This is what I tried (see here):

body {
    overflow: hidden;
}

span {
    border: solid 2px blue;
    white-space: nowrap;
    text-overflow: ellipsis;
}

Essentially, I want the span to shrink with ellipsis when the window is made small. What did I do wrong?

Answer 1

You need to have CSS overflow, width (or max-width), display, and white-space.

http://jsfiddle.net/HerrSerker/kaJ3L/1/

span {
    border: solid 2px blue;
    white-space: nowrap;
    text-overflow: ellipsis;
    width: 100px;
    display: block;
    overflow: hidden
}

body {
    overflow: hidden;
}

span {
    border: solid 2px blue;
    white-space: nowrap;
    text-overflow: ellipsis;
    width: 100px;
    display: block;
    overflow: hidden
}

<span>Test test test test test test</span>
