I have a few questions

http://endlessforest.org/community/node/30683

Does anyone know how to get it to stop jumping down the page whenever you click on a tab? Also, does anyone know how to get rid of what seems to be an... extra table space between the tab links and the descriptions themselves? I've seen people do it before, but I'm not sure how and I can't figure it out.

Thank you in advance for any help!
