Hi

Modern websites do contain a lot if <div>'s - the current HTML specifications have deprecated older methods of controlling page layout and are also more strict on the use of tables, which were often used incorrectly, to control layout.

The use of the <Div> element enables greater control over content layout and isolation and as they contain the website content it would be pointless, and frustrating to edit, if they were in separate files to also be downloaded by the web browser in addition to those it already has to download to make jQuery work.

You will also find that the generated websites are reliant on jQuery for many functions eg photo galleries, so much so that jQuery has become an 'almost de facto' standard component for many website builders and software like Web Designer.

. . . . how much non-optimised code could affect the speed of a web site ? . . .

A web page consists of a series of what are basically text files ie the HTML, CSS (style sheets) and other scripts such as jQuery functions, needed to tell the browser, from their content, how to assemble and style the web page, where to download the images, animations and video, which may incorporated into the web site, and perform the necessary functions to make picture/video galleries, live content and many other features work.

It is the image, animation and video that must be optimised - the download speed of the text files is minuscule in comparison.
