You have many syntax errors you need to resolve first. Use the Analyze CSS feature in the CSS module.

With your current CSS, it is very difficult to figure out how your various grid areas related to the html structure. It would help by using names which describe the sections they pertain to.

thanks a lot,finaly i solved the problem! :smiley::smiley:
