Rather than redesign table-laden sites to css/div tags layouts – does it really make sense to wait on html 5 to do so given that 5 will have structure markup? Assuming 5 comes into use within the next year or two…albeit buggy at first.
I’m still on the fence, especially if current css sites will yet then need to be redone again with the introduction of html5, then there is debugging the css design for Firefox, etc, add basically having to strip the sites down to their core essentials and transform them into a much less readable fashion for an editor (human and software). There is also the new behaviors to deal with, like whether things stay put, figuring floats and absolute positioning throughout, etc, That’s one thing I can say about stalwart tables, they hold things and don’t let them out!
At the same time - wondering if css layout might be around for some appreciable amount of time, or, whether it will turn out to be a vogue session – I have hundreds of pages to convert.
Most of the sites have been around for more than 2-3 years with a couple near 10 years, although my thoughts are that the div’s s may help their search engine rankings – as far as mobile, transferring to divs could help even if they’re not fully device tested. Even though few searches currently come from mobile devices (informational based sites that are for the most part bring non-locally oriented searches)
When and with what to convert, that is the main question here.
However one major site needs restructuring/major total edit right now.
