need help understanding a line of code
 

I was validating my code with w3c validator and it pops up this line.
I'm not sure what it means, I have not seen the extra
before, what does it do?

<-- 300px -- > is probably doing nothing. It is commented out using html comments, and done improperly at that. :-)

It should be <!-- 300px -- >

Sorry for the w3fools link:

I would just remove the offending little bugger.

I wondered if that was the case. I didn't want to delete it without checking first.

It is inside the style attribute, so I believe the correct way to comment this is /* 300px */.


I would do the same, unless there is a chance you will revert the change (from 300px to 1px margin) back :)
