Why HTML/XHTML Verification is Required?

There are various reasons to verify your website before hosting it over the internet.

· Any webpage quality depends on how well you have written your webpage. It

should be syntactically correct and should pass all the Quality Gates.

· When any search engine does indexing for your webpage content, it might get

confused if the HTML tags are not written properly, and much of the webpage

content might not be indexed properly.

· There might be many HTML tags, which you are using in your webpage but then

have been depreciated and many of the search engines do not support them.

· Consistency, HTML Code Beauty, Process Compliance are always appreciated by

good webmasters.

What is W3C Compliance?

W3C is the World Wide Web Consortium and since 1994, the W3C has provided the

guidelines by which websites and webpages should be structured and created. Here are

the links to validate your web pages:

· Validate HTML/XHTML File against W3C Standard HTML/XHTML Validator.

· Validate CSS File against W3C Standard CSS Validator.

While verification, you may get errors along with appropriate reasons. All the validations

will be done using XHTML DTD, which is a refined version of HTML.

Rules for W3C Compliance

The following rules are to be following while developing a webpage:

· Use XHTML declaration statements to start every XHTML page:

<!DOCTYPE html PUBLIC

"-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd">

· Every tag must be closed.

· The head and body tags are now mandatory.

· Empty tags get a terminating slash. An empty tag is a tag that doesn't require an

end tag. Examples include and <hr>.
