Subject: [WebAIM] 3 column layout question

Hi there,

I need to create a 3 column liquid layout; which I've done by
essentially
having 3 divs one floated left, one floated right both of them with set
widths and then one div in the centre, without a set width.
The basic design works well across all browsers, and no hacks were
needed.

However what bothers me about it, is the HTML is structured in such a
way
that the left div which will contain the main navigation, and the right
div
which will contain links to documents or other less important
information,
appear before the middle div containing the sub navigation and the main
content.

My question is, for individuals who rely on screen readers is this a
problem?
There will be a skip to content link on the pages.

If it is a problem, then I'd really appreciate suggestion on how to
create a
3 column liquid layout that will work on all browsers, without the need
for
hacks or Javascript?
I've looked at a variety of ways to do at and this one seems a good way
to
do it.

Below I've included a simple version of the markup and CSS that will be
used.

Thanks,

Martin

----------------------------------------------

#left {
float:left;
width:150px;
margin:1px; padding:0;
border:solid 1px blue;
}

#middle {
margin:0 160px;
border:solid 1px green;
}

#right {
float:right;
width:150px;
margin:0; padding:0;
border:solid 1px red;
}



Provided there is a skip to main menu, skip to 2ry menu and skip to
content link I see no reason why this should be an issue.
