Align checkbox labels (web)

Question

A picture says more than a thousand words?

I would like the second (and consecutive) lines to be aligned with the first. Any ideas?

Html is

<input><span>text</span>

Answer 1

.thing input { float: left; }
.thing label { display: block; margin-left: 2em; }

<div class="thing">
    <input type="radio" id="potato"/>
    <label for="potato">Text over multiple lines should be aligned properly...</label>
</div>
