I'm trying to add highlighting features to a pre tag.
I want it to look like GMail higlight and spell-checking feature, but I
don't want to break the pre tag text into small span tags.
Instead, I want to position a span with a background color over a specific
text, so the text will look
I tried setting the z-index style of the span to -1, but on Firefox, this
completely hides the span behind the pre.
I tried setting the span opacity's to 0.5,, but that makes both the text
and
the span blurred.
Can someone suggest a way to accomplish that on all browsers?
