I have developed a pretty annoying problem in WordPress. I have set up my posts in a way that categories, tags and the excerpt appear on the same line. Everything would be fine, except the space between the excerpt and the tag is bigger than that between excerpt and category (if a tag is not posted). I would like the space between everything to be 5px. If I lower the tags-links right margin to 1px (like the category one), multiple tags get nudged together. I might be overlooking something simple here, but I don't see a problem to this solution, because if I set the CSS values of tags and categories to match, the outcome for them is different for some reason (category links never get merged like the tag links do).
