The two divs below should be on the same line, since they are display: inline-block.

<center>
<div>This is div one.</div><div>This is div two.</div>
</center>

The two marquees below should be on separate lines, since marquees fill the width of a containing
block by default.


<span>
<marquee>This is div one.</marquee>
<marquee>This is div two.</marquee>
</span>
