Input box 100% width, with label to the left

Question

I'm trying to have a fluid input box with 100% width, while having the label floated to the left. Here's what I currently have:

.left {
  float: left;
}

input {
  width: 100%;
}

<form>
    <label class="left">Name:</label>
    <input class="left" id="name" name="name"/>
    <div class="clear"></div>
</form>

This works, however it drops down below the label. If I use a parent div to assign the floats, then it doesn't span 100%. Any ideas?

Thank you!

See: http://jsfiddle.net/r2769/ (resize the window)

CSS:

.left {
    float: left;
}

.left2 {
    overflow: hidden;
    display: block;
    padding: 0 4px 0 10px
}
.left2 input {
    width: 100%
}

HTML:

<form>
    <label class="left" for="name">Name:</label>
    <span class="left2"><input id="name" name="name" /></span>
</form>
