Well, here I am ... trying out a Drupal 8 installation. This should be interesting and educational. 

For a theme, I've chosen to try out The Drupal8W3CSS theme. According to them:

Drupal8 W3CSS Theme is using the W3.CSS framework with built-in responsiveness: Smaller and faster than other CSS frameworks. - Easier to learn, and easier to use than other CSS frameworks. - Uses standard CSS only (No jQuery or JavaScript library). - Speeds up and simplifies web development. - Supports modern responsive design (mobile first) by default. - Provides CSS equality for all browsers. Chrome, Firefox, IE, Safari, and more. - Provides CSS equality for all devices. PC, laptop, tablet, and mobile.

To get started, I'm going to build my own image gallery. Let's see how that goes.
