Hey, I'm new in wordpress and I forgot a big part of my CSS courses so I need your help. I'm using Bueno theme and I'm trying to add a column on the sidebar made of multiple images that will became buttons. The problem is that hole blanks appears within images so the "break" the column. You can check how awful does it look nowadays at http://solidarispoblesahraui.wordpress.com.
Is there any way to delete these "margins"? I read that, in some cases, these blank holes are images and you can create your "own blank hole image" and replace the original one with yours but I think that's not the case with Bueno.
another hand... I would like to change the background. I've tried to put a photo but I can not see any change. Furthermore, I've tried to change the colour and no difference appeared. Is that maybe caused by a transparecy problem? That sounds too much wierd for an amateur...
The blog I need help with is solidarispoblesahraui.wordpress.com.
