Hi, I am fairly new to html and css, I have been learning through designing my own basic layout, which has been going ok till now.

I managed to create a basic 2 column layout which was fine, but when i added a 3rd column things went wrong. Both sidebars are being pushed downwards. The tops of both sidebars are suppose to be in line with the top of the center content area.

I have searched for a solution but havnt had any luck.

This is really frustrating so any help would be much appreciated.

Thanks in advance.

Your main containers are width: 95%; but your divs inside are in px so they won't fit unless the window resolution is wide enough.

If you want a fluid width, all elements must have % width including side margins and side padding and images, all totaling 100% (100% of the 95% containers). If you have side borders, these can't be sized in % so you have to make the other items total 97% or 98% to allow for the side borders in px.
