Why It Makes Business Sense To Develop Your Site With CSS And Semantic Markup
One thing that I have learned in over a decade developing web sites is that the 'Net is continually changing, and to keep up you need to change with it. One of the more recent developments in web design is the use of CSS and semantic markup. CSS and semantic web design has several benefits: clarity in code, browser and other web-enabled devices compatibility, seperation of content and presentation, smaller burden on bandwith, and better visibility to search engines.
Back in the day, we designed sites with tables and hacked those tables into doing things that they were never meant to do. The table tag was designed to display tabular data, not as a way to render the layout of a website. Unfortunately, a better alternative did not exist, so we used tables. This made for inefficient, slow loading sites with code that was very hard to read and maintain. Defines sematic markup like this.
Sematic pages "supply information for Web search engines using web crawlers. This could be machine-readable information about the human-readable content of the document (such as the creator, title, description, etc., of the document) or it could be purely metadata representing a set of facts (such as resources and services elsewhere in the site). (Note that anything that can be identified with a Uniform Resource Identifier (URI) can be described, so the semantic web can reason about people, places, ideas, cats etc.)"
These days, hip designers and developers use CSS extensively to create beautiful, fully standards compliant sites. CSS-based layout allows us to develop sites that will degrade effectively--that is that they will be viewable on all types of devices such as PDA's, cell phones, T.V.'s--and will work correctly on devices that don't even exist yet as long as they are standards compliant.
Most importantly, developing sites with CSS allows us to effectively separate content and presentation. Have you ever looked at the source code of HTML pages that were created with a table-based layout and wondered "what the heck is going on here?" You see lots of opening and closing of tables and table rows all mixed together with textual content and graphics. With a clean, CSS-based layout you can create pages that are easily understood by looking at the source, making them easier to understand, maintain, and update. Look at the source of my
company site http://www.vp3media.com and then look at the source code of this site that uses a tables based layout: http://webservices.org/. Big difference, huh?
If you have a site with high traffic, you can significantly reduce the amount of bandwdth used by transitioning from a table-based site to a CSS-based layout. If a visitor to your site doesn't have to load all of the code needed to render those tables and spacer gifs, you are transmiting less data.
CSS also offers search engine optimization benefits over tables. If you have a tables based business site that relys on Internet traffic to turn a profit or aquire new clients you will see real advantages by switching to CSS. When a search engine spiders your tables-based site, they retrieve a large amount of content that has nothing to do with you business. When search engines spiders a clean CSS-based site, the majority of content retrieved will be textual content that describes your business. The ratio of content-to-code is higher with CSS-based layouts.
We've all seen search engine descriptions that don't make any sense; that's because search engine spiders use a top down method for retrieving information. Whatever is topmost in your document, the search engines are going to think is the most important part of the document, and therefore should be used as the description. Since we seperate content and presentation with CSS, we can put the most important information at the top of a document no matter where it is actually displayed on the page. Try that with tables!
I hope this article gives you an overview of why it is important to transition from your current tables-based layout to a fully valid CSS implementation. If you don't have a web site, but are planning on launching one in the near future, make sure you tell your developers you want a CSS-based implementation.
