Following the creation of a first Weebly blog, we decided to migrate to Wordpress. Given the needs, I decided to create the theme from scratch (no template here).
So I started by creating a development universe with Gulp / Composer / Bower and Phing to allow me to develop and deploy on different server instances more effectively. Then, I created the Lifemotiv Blog's theme that is very inspired by the design of the Medium blog platform that is known for its very successful user experience.
The project is still evolving today. Feel free to go have a look and tell me what you think.
