I have defined a section ..suppose 'centercontent' and a few other sections in the page.
Now, based on the content entered within the section, i want the size of teh section (i mean height) to increase.
How do i go about it?
I have tried keeping the height at 100% , AUTO, Nothing at all , n defined a specific height..
Nothing helps.
I am using dreamweaver for designing.
Please help.

Could you show your code?

Give the element a width and do not set the height property.
