When I installed the Deko Boko plugin to provide a contact form in WordPress, I discovered an annoying bug.

One could also edit the dekoboko.css file directly and change this element’s CSS. I prefer to edit my contact page instead of editing the Deko Boko files to make upgrading the plugin hassle-free.
