First, When you separate presentation from structure i.e. use css for formatting, you specify the formatting in a css file instead of specifying format information all over the html file. This reduces the size of the html file. If you think about only one file, the difference is not much but when we deal with thousands of files or may be hundreds of thousands of files, impact is huge.
Second, if you replace any text content that is shown with images with plain text and css, you can reduce the size and multiple requests made to the server.
With warm regards

Thanks srinivasu ,
Yes it does helps , but isn't it so that "separating content and
layout " and doing "semantic html" are basically the point to justify
for " General Development Best practices " ?

Hi Ravindra,
I didn't see Srinivasu's mail so I understand you have mistaken me for Srinivasu.
Yes, these are "General Development Best practices " and many of the accessibility problems stem from violating such practices.
Around 50 percent of WCAG 2.0 guidelines can be classified as Web Development Best practices.
With warm regards

I totally agree with Dinesh. Accessibility is more about using right techniques and best practices.
Dinesh,
I wrote to him off the list earlier and I just wrote the same thing that you have written.
Regards,
Srinivasu

There is another aspect here, which is surplus code.
Have you ever seen some of the code generated by CMS packages or tools.
My recent memory is of the GWT (google widget toolkit).
The number of embedded divs you can have just for a simple label on the
screen somewhere is amazing.
Last time I checked, GWT did not generate accessible code, but what I am
saying goes beyond that. We seem to be at the (I hope) tail end of an era
where no consideration whatever was given to how you get something onto the
screen. Tables where each cell contained a one celled table, etc.
I think that Accessibility practices are about thinking of the bigger
picture, and realising that
<div>
<div>
<div>
<div>
<div>
<span> hello</span>
</div>
</div>
</div>
</div>
</div>
is just dumb. (but really you see this in some generated code).
I don't imagine that it helps speedy DOM calculations either, in general
(client).
It seems that excessive coding, inaccessibility, and non-standards
implementations all go together.
The stack of divs above is not inaccessible, but... if you were working on
accessibility, you'd notice it, right, and say to yourself... what the h*^£
is that?!
Good day to all

Yes, something similar happens with asp.net and portlet factory as well.
These tools also generate lots of tables and embedded style information which increases page size.

Dinesh,
I disagree about ASP.Net adding excess code. True, at one time the generated code was just plain stupid. But todays generated code is clean, compact and compliant ... especially if you create an MVC app. MVC apps have a greater separation of data and presentation that allows a developer to code the html elements almost anyway they want.
