CMS Quick question

[محروم.كوم]

I want to add a square adsense in ad in the top left of article pages and the text to wrap around it. When I do this with wordpress I use this code
Code:

Adsense Code



However, I don't think that is valid. I checked one of my sites using it and it didn't pass validation.


My question is, what would be the correct way to add this into my article page template? what code should I use? __DEFINE_LIKE_SHARE__
