Defining Validation

If you are unfamiliar with Validation then you may about it by going through the definition:
Validation is process of refinement of HTML or CSS code and assurance to that coding is free from errors and making it as that it can meet the standards set by the W3 Consortium.

There are various types of validators used in which some may check only errors, others may suggest you about your code and tell what the way of writing code is.

Need Of validation:

There are many persons who are against the validation because of some of the reasons as:

  • Validation does not always guarantee that page will work.
  • It is time consuming process, because making every pages error free consumes much time.
  • An average visitor does not see your page source code.

But, there are some reasons for adopting the validation of HTML and CSS codes some of them are:

1. It Helps in Resolving Compatibility Issues

There are various types of browsers used in the industry and there is a huge scope for new software’s and tools. So, the code should correct and compatible for all of the browsers and should be updated with technology and software coming in next era.

Validation of the XHTML, HTML and CSS codes does not always ensure the compatibility to the browsers but it propels you towards right direction. If you are still reviewing your files in multiple browsers but, since I am here dealing only with structure, the browser compatibility issue will not rear its ugly head as it will with CSS.

2. Increased Search Engine Visibility:

Google attract towards the well formed and well structured site. Here we may talk about the search engine spiders, they crawl through web and index the pages of your site and show visibility of your site in the search engines. So, you must use those attributes which may easily crawled by the search engine spiders. Use codes and content for your site as much possible. If you are using Image anywhere must use the title of image and tags in code will make it easy to crawl. So, the error free codes are important for your site for increasing visibility to search engines.

3. Learn Think and Apply:

Once you starting validating your files you’ll find the process to be an invaluable learning experience. Validation itself will teach you what the best ways to create your XHTML/HTML and CSS codes are. The more you use validation, the faster you’ll be able to create well-formed documents because you won’t be making the same mistakes over and over again.
