Let span fill remaining width?

Question

I have the following li item:

<li>   <span style='float:left; background-color:red'>a</span>   <span style='float:left; background-color:green'>b</span> </li> 

I'd like the span on the right to fill whatever width is remaining in its parent li. Is there a way to do that?

Thanks

You don't want to float each of them left, only the first one, and then make the second one display in block mode:

<li>   <span style='float:left; background-color:red'>a</span>   <span style="display: block; background-color:green;">b</span> </li>
