When building websites, we spend a lot of time with customers going through the available themes. We use iThemes Builder for the majority of the websites that we build, so I put together an example site to show all of the Builder child themes: http://the-internet-adventure.com/examples/.
Check it out, I set it up with 2 different methods to preview the 30+ child themes that we have available. I’ve also set up pages that shows all the available typography as well as 4 different layouts and a page showing a variety of widget layouts.
I have another post coming soon about my favorite themes, plugins and tools for WordPress. Keep an eye out for it.
