span inside div and different font size alignment

span inside div and different font size alignment

I have 3 spans inside a div.
<div class="align">
<span class="a">Title</span>
<span class="b">Someinfomation</span>
<span class="c">Toright</span>
</div>
for making the c class to align vertically, I have to use margin-top to
fix it however, for IE7 looks differently. Here is online sample:

Yes, I want IE7 works as well. If someone could help me with a better
solution?Thanks
