Your theme controls what your WordPress site looks like. Some themes have limited options. Some themes have many options. You can get themes for free. You can pay for themes. You can have custom build themes.
Make sure when trying a theme you get it from someplace you trust. I highly suggest using the WordPress Theme Repository to avoid installing a malicious theme.
Weaver Extreme Plus
Weaver has released a new theme, built from the ground up with all new features. It’s called Weaver Xtreme.
Yes . . . I agree. “Xtreme” is over used and doesn’t really mean anything. I refer to the theme as “Weaver X” when talking about it. Regardless of my opinion of what Bruce has chosen to call his theme it works. It works well. It’s highly customizable and the support for the product is top notch. The Weaver support forum has never failed me yet.
