Builder is a theme framework from the folks at iThemes. Builder’s Layout Engine allows you to quickly and easily create any page layout you like without having to be a coder. With more than 45 child themes (and more always in development) it’s easy to find a design that fits your website. To customize your theme, you can use Builder’s Style Manager to tweak the design to your liking, all without ever touching a line of code. Builder also has built-in SEO options, to make sure your site can be easily found by search engines.
