In the inspiration of the month, here is a Halloween WordPress Theme-Skulls for sale!
You can install and activate this theme and have no worries about overwriting your current theme. Headings, links, controls etc have all been formatted to work with what you already have laid out in your current theme!
Remember, it does not overwrite your bullets, accents or dividers that you have active. But no worries, I have provided you with 3 different bullet/accents to use. They are the icons used in the Vertical Menu, Content Header and Block Header.
This theme does not come with a divider or link back banner as I have designed it as a temporary theme for Halloween, HOWEVER I can always design one for you if you just LOVE the theme and wish to use it permanently!
When your ready to switch back to your websites main theme, all you have to do is activate it. Again, you will have to change your bullets and dividers.
