Limiting the number of tags in sidebar

[rebecca_in_blue]

Can anyone tell me if it's possible in Smooth Sailing to limit the number of tags that appear in the sidebar? The CSS coding that I use is below....

/*TAGS PAGE*/

.tagstable, .tagstable td {
border: 1px solid #dddddd;
}
.tagstable { width: 500px; }

...but there is a LOT of it, so if you don't want to sludge through it all, here is the part of the code that applies to the tag list in the sidebar (I think):

.sidebox #tags_sidebox {
text-align: center;
}

Thanks SO much in advance to anyone who can help! I've been trying to figure it out for a while and having no luck!
