Thanks for your reply,
I have a design that i coded in css and xhtml and i want to submit it in here to have people opinions and see if im doing things wrong or not and also to share the work, cuz if its good then people may use it in something.
The best place is probably the review section where you can post your design and other will review it for you. Some comments may be harsh but you'd rather the truth than someone beating around the bush.
Please note that before you can post in the review section you have to review three other sites first or the system won't allow you to post yours.
