Question

[MikiHeart]

This template is pretty easy to make. It's basically a copy of the old Neopet's layout.
It always stays to the left so it doesn't matter what size browser the person has.

You can edit the menu for Mysidia, I'll have to find where it's located though for you.

I'll be making some free to download layouts in the future, which will be based on elements I have see on popular pet sites. But I don't have any available at the moment.

As for changing the background, how do you mean?

Background colour? Background image? Do you want it to show a random colour or image, or one you can just set and change yourself?
