Could anyone please help me. I am having trouble with the hover state on my menu. I want the ‘highlight colour’ to fill the whole button like it does on this site, (see grey highlights on main menu) using only CSS (no images).
It sounds like you need urgent support and volunteer-based forums like WordPress.org aren’t the way to go for that. Sometimes threads don’t get answered at all. Try WP Jobs or CodePoet for paid support.
