Okay, I'll try explaining this the best I can. I am creating a web page document that serves as documentation for a program. It needs to be cross browser friendly and completely dynamic. I am using a table, the left side contains a hierarchical navigation tree, the right displays the information when a branch of the tree is selected. The tree is very long though, so I want to use overflow:auto to create a vertical scroll bar. But this seems to only work if the height for the table is static (height:800px) instead of dynamic (height:95%). Does anyone know how I can get the overflow to associate with height:95%?
