html - vertical-align: middle doesn't work

Question

The css property vertical-align: middle does not work in this example.

HTML:

<div>
  <span class='twoline'>Two line text</span>
  <span class='float'>  Float right  </span>
</div>

CSS:

.float {
    float: right;
}

.twoline {
    width: 50px;
    display: inline-block;
}

div {
    border: solid 1px blue;
    vertical-align: middle;
}

The span that is floating on the right is not vertically centered with respect to its containing div. How can I have it vertically centered?

The above code is in this fiddle.

Answer 1

You must wrap your element in a table-cell, within a table using display.

Like this:

<div>
  <span class='twoline'>Two line text</span>
  <span class='float'>Float right</span>
</div>

and

.float {
    display: table-cell;
    vertical-align: middle;
    text-align: right;
}
.twoline {
    width: 50px;
    display: table-cell;
}
div {
    display: table;
    border: solid 1px blue;
    width: 500px;
    height: 100px;
}
