HTML Code Checkers

It's easy to forget a closing tag, a bracket or quotation marks but not so easy to find your mistakes when checking over your code. Often, you don't know that there are any errors in your code until you run it through an HTML code checker. Sometime mistakes are made due to bad coding style or taking shortcuts. Ironically, some shortcuts turn into the biggest nightmares when your code isn't working and you have to debug it. Here are some HTML validators that will make things a little easier for you.

HTML Validator
This is one of the easiest tools to use. All you need to do is type in the address of the live version of a page and you're done. The code of the page is displayed below along with a list of errors and warnings. The line number that is displayed beside the error message is linked up to the spot in the code where the error occurred making it easy and quick to fix. Suggestions of possible fixes are also provided.

W3C MarkUP Validation Service
This is a free service that checks documents like HTML and XHTML for conformance to W3C recommendations and other standards. It gives you the option to check live pages as well as those you haven't uploaded yet by specifying a path to the local file. There is also an Extended Interface available if you want to set any advanced options, and a Extended File Upload Interface if you want to validate uploaded files with advanced options.

Using an HTML checker is highly recommended for webmaster who wish to get their site into Google and other popular search engines. Some errors might prevent your site from being indexed properly resulting in poorer performance as some pages may not rank for their keywords.
