thanks for your replies.
what I want to do is to be able to insert a youtube video inside a page (not the home page) with a width of 640, but it´s automatically cut off because the width of the theme is limited to 500px.
so... could I insert a video of 640px width even with this 500px limit and that the video were not cut off?? ...using some css trick???
I know that if I change the global width I am able to do it, but I would like to keep it in 500px.
just one more question, as I change the width of everything I see all my blog is moved to the right of the screen,
how can I put it again in the center?? (just in case I decide to resize the global width)
thanks a lot from madrid!!!
