I have done some research on layouts and apparently using HTML tables
to layout your page is BAD. So the alternative is to make use of div's.
I have the following layout designed and want to know how I would implement this with the use of div's. Specifically, how I would get the 3 panels at the top to be aligned vertically with a panel at the bottom that stretched the length of all three panels.
Would I be able to do this purely with CSS and HTML?
Here is the design:
The <table>
element has no semantical significance when used for layouts. It should be used for data grids only.
That said, CSS has a good alternative:
display: table;
and
display: table-cell;
See this example.
Your layout consists of two separate "tables". There is also table-row
to create columns with the same width over multiple rows. It doesn't have alternatives to colspan, thead and other table specific elements, but it should do the job for a simple layout.
