Re: 3 column layout question

Hi Martin,

I'm not sure of the screen readers side of things but as far as putting
the content of the page higher in the code than the navigation you will
want to use absolute positioning.

I have just developed a site www.babysafetyshop.com using this method of
positioning. If the left nav has something like
position:absolute; width: 200px; top: 85px; left 5px

then your right column has something like
position: absolute; width: 250px; top: 85px; right: 5px

and the centre body area has
position: absolute; top: 85px; left: 210px; right: 260px

you can then put the code for those blocks in any order in the HTML.
Have a look at the code and the CSS for this site and you can see the
whole thing in action.

I have not done much testing for accessibility as I am still new at this
area of things. Maybe someone else on the list can give some insight as
to whether this kind of coding causes problems for JAWS etc.

Hope that help.

Regards,
Jon
