    This is certainly a work flow smoother. I use it more and more given how accurate the criticism and non-judgemental too. On testing it with this page W3C returned 5 errors. Question- how often or much do you use the validator on your own sites and why?

Posting Code

Markdown is supported in the comment area, so you can write inline code in backticks like `this` or multiline blocks of code in in triple backtick fences like this:

<div>Example code</div>

You don't need to escape code in backticks, Markdown does that for you. If anything screws up, contact us and we can fix it up for you.
