[Solved] Hiding Left & Right Hook when empty

[bustin]

Hi, I'm currently making a theme from scratch, i have a little problem

could anybody help me in pointing out what line in the css that point out to hide left & right column when they are empty?

I wanted the position to be like this


But what I get is this


it seems like the left & right column still there even though there's no content.
I already copied all the header & footer tpl files
so I think the only problem left is in the css files

any help is very appreciated

They probably have a defined width, which is why they are taking the space (even when empty).

Do you need to use them anywhere on any other page, or do you want to get rid of them completely?

Thanks 4 the reply, I'll be using them on other pages, I only want to hide them on some pages (the ones that aren't using any left or right hook)
The problem is when I changed the theme to Presta, the left and right column disappear on that same page.
I check the header.tpl, it's the same with the presta header.tpl
I also follow the left and right div style from the presta (they also have a defined width)
so i'm guessing it's somewhere on the css, but I don't know which line that is

It's solved, it's just a problem with one silly line!

on the left/right column div style:
DO NOT USE ANY TOP MARGIN/PADDING

that's the only problem, I looked for hours an the problem lies in 1 silly line!
after I delete it, ta da my left & right hook automatically hidden...
