I would like a way to make the content wider on a single page. It is set to full width but obviously restricted by the max-width property, which leaves a lot of blank space around the content at the moment. I want to override that and make it 90%.
I don't want to change this property site-wide, but just for this one page (and any subsequent one which need the extra width!).
Is there a custom css method which can be attached to a single page?
