It has always been my choice to focus on the server side rather than the client side. But my recent exploration into Bootstrap is really turning things around. The Bootstrap grid takes the complexity out of html layout. And the success of Bootstrap has created a market for Bootstrap Themes at {wrap}bootstrap, Start Bootstrap, Creative Market, et al. It is absolutely possible to create a good looking, mobile ready web application without an advanced degree in browser specific behavior.
I used to say I was full-stack because I could build a functional web application in basic html and css. But I wouldn’t have been proud of the front-end. With Bootstrap and Datatables in my toolkit, I don’t need to apologize for my front-end.
