Bootstrap
I recreated my entire website using Bootstrap which is is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web.
It has given me the ability to easily create a professional looking responsive website that allows my website to fit properly on any device and give visitors the freedom to view it as they see fit.
