Do you want to keep the same relative font sizes? That is, the current tag cloud sets the font size based on how often the tag is used. Here are some rules which you can add to affect the font sizes:
.widget .tagcloud a[title="1 topic"] {
font-size: 8pt !important;
}
.widget .tagcloud a[title="2 topics"] {
font-size: 16.4pt !important;
}
.widget .tagcloud a[title="3 topics"] {
font-size: 22pt !important;
}
The values listed are what’s currently in effect. The first rule is for tags which have the fewest counts, and the subsequent rules go up from there. It may go higher than 3 topics, I just don’t have enough content on my test site to see if it does. If you want to make all of the tags the same size, then you can just modify the rule that I gave you earlier by adding this property to it:
font-size: inherit !important;
This is the value that’s used in your previous blog.
is it possible to increase the padding above and below?
Just change that first zero to some other value (be sure to add the units px after it).
