Hi,
I think i understand liquid layouts, in that they expand to whatever width the browser is resized to, and fixed width layouts are ones where the page is wrapped in a div and is set a certain width, and when the window is rezised the layout will remian the same size? Am i understanding this correctly?.
thanks for the help.
