Code:
<style>
.style1 li { width:220px;
float:left;
}
</style>
<ul class="style1">
<li><input type="checkbox" value="1">Value</li>
<li><input type="checkbox" value="1">Value</li>
</ul>
<span style="clear: both;">Hello</span>
With the above code the span doesn't clear the list. But it does if I make it a block element.
