I can’t believe these debates are still happening. A number of blogs have been spreading around this rant about why CSS is bad at layout, and the old debate of CSS vs. table layouts has been reignited.

The one big thing people seem to be forgetting is that CSS can do table layouts without table elements! So the main benefits of table layouts are possible in pure CSS layouts using divs or other elements. The main problem with CSS table layouts is that Internet Explorer 7 and below didn’t support those parts of the CSS specification (while all other browsers have supported them for a long time now). But that’s a shortcoming of Internet Explorer, not CSS, and Internet Explorer 8 will have support for CSS table layouts.

I’m not saying that CSS table layouts are perfect. There are two other significant shortcomings of CSS table layouts:

First, CSS 2.1 doesn’t provide for a way to specify that a cell should span multiple rows or columns (as HTML’s rowspan and colspan attributes allow). In most cases, this limitation can be worked around by mixing the CSS table layouts with other CSS layout methods.

Second, CSS table layouts usually require lots of nested divs. It doesn’t require any more elements than HTML table layouts require, but it’s still quite bulky compared to other CSS layouts, and it demonstrates how dependent CSS still is on the underlying markup. CSS 3’s pseudo-element model will help mitigate this issue somewhat.

However, if the argument is that CSS doesn’t support the kinds of flexible grid layouts that HTML tables support, that argument is simply incorrect. Sure, CSS isn’t as markup-agnostic as it could or probably should be, but the use of HTML tables for layout is not a better solution.
