[Plugin Code Snippet Library] Code hidden by slidebar

I’ve started posting one line code snippets, and the first one gave me trouble in some browsers. In IE and some versions of Chrome the code in the snippet-area are hidden by the slidebar! Are there an easy fix to this or did I do something wrong ?

Working fine in Firefox though…
