Hi,

I want to say you that i did not check your layout and css manually.

But this types of problems are generally due to margins.

So check your margins and padding area in your CSS.

Because some times we fix the length and width of area and after more content its not working properly and due to this other area disordered.


Thanks
Alex

Have you got a URL where we can see it ?

thanks to all who reply to this message and thanks in advance to those who are yet to reply.
to lowcostwebhosti,appreciate your effort but i am new to css.since you said the problem might have to do with the margins and paddings being fix so setting them dynamic might solve the problem.the problem now is how to set them dynamic.

LadynRed, well i am not having a url yet . i just finished developing the website and i'm trying to insert the real content of the site after which i will host the website then i can have a url.it is during insertion of the real content that i encountered that problem.if there is any other way please help.thank you.

Add overflow:auto to your #wrapper that will clear the floats inside it. You also need to read the stickies about clearing your floats.

You really don't need the position:absolute on #header, you can put that where you need it by floating it.

I would also recommend that you put the #logo INSIDE the #header div. Without being able to see what you're trying to accomplish, this would allow your #left column to sit UNDER the header and logo where you seem to want it to go.
