Hi Ben,

One other thing I did this weekend was to play around with using CSS
sprites rather than <img> tags. This is important for us because it
reduces the load on our servers (fewer http requests). We now have HTML
that looks like:

<a href="javascript:.."><span class="class1"></span><span>Get a new
challenge</span></a>

"class1" has a background image set, and we use some tricks with
positioning to hide the <span> for visual browsers (without setting it to
display:none).
Are there any issues with doing this?

It would fail visually when CSS is available, but images are disabled
(for example, to save bandwidth for dial-up users or people who pay by
the byte for downloads).
