One boring day, I tried to work on my HTML and CSS codes using Notepad (as I was too lazy to set up Frontpage or Dreamweaver on the laptop that I was using for that day). I was confident I have typed every code correctly (I was just actually typing a code from my book). But when I tried to view the page both in IE and Firefox,they showed some slight difference. Alright, that's expected. But the style that I wanted did not display at all. So I checked my codes. Re-checked it for what it seemed a hundred times to find out that one missing ">" on my HTML code. *phew* 

Ever since I started working on HTMLs, I wished that they have included a debugger in every HTML editor. So far, they haven't. Thanks to Notepad++, my coding became easier. But more thanks to W3Cs HTML validator, I've learned that I wasn't following HTML Specifications and/or formal HTML coding. LOL!

According to HTMLHELP, Validation is a process of checking your documents against a formal Standard, such as those published by the Worldwide Web Consortium (W3C) for HTML. It's like a grammar- and syntax-checker, eh? Kewl!

Anyway, here's a list of some HTML validator that SAMS suggested (you can Google some more if you're not satisfied):

• W3C HTML Validation Service
• HTMLHELP Validator
  

Stop chasing down your mistakes, let validators do their job!
