opera and w3 valid websites?

Someone posted today a comment to my blog site:
http://www.web-development-blog.com/

he told me that the website is not accesible in opera and this is because some invalid code...

I checked my site and it is valid but the site looks very bad in opera, what is this browser? only table layouted websites are possible?

No Opera works with tabless layouts also.

at least opera 9 works :)

I checke the site with 8.54 and it was really bad... I will upgrade to version 9 first

Btw your site has some problems with firefox too...

I know at the end of the page there is a glitch, strange is that this is gone if you refresh the page...

maybe it is a css bug, but anyway you should fix that as your blog becomes more popular....

yes there are more "design" bugs (it's in the template I bought) I will fix this soon...
