When a designer codes a site's architecture through a table tag, then its file size cannot be as light as Div based sites, as they tables exist physically on the site and have to be downloaded or uploaded by a browser first.
A WEBSITE must have a good navigation system, so that every visitor can enjoy and have a great experience. It should have light weight files size for every web page, so that they can be downloaded in less time. It also needs a soothing page design and be browser friendly, that is, it can be viewed same on all popular browsers.
There has been a lot of debate over which form of encoding is better for websites – through Tables or DIV. Let us examine both.
When a designer codes a site's architecture through a table tag, then its file size cannot be as light as Div based sites, as they tables exist physically on the site and have to be downloaded or uploaded by a browser first. When it comes to Div, this does not happen as tags here are CSS based containers, which are defined by IDs and Classes.
Many search engines like Google, Yahoo, and Msn read CSS based websites easily and quickly, while they nowadays ignores tables. So, DIV based sites are better positioned at being ranked highly on search engines. As every website is designed for getting a good amount of business and to target a global audience, more and more of them are shifting to DIV based coding, giving CSS more and more acceptance in the world.
