WordPress theme frameworks are starter themes with basic design and a lot of features ( few of them had integrated theme options panel ) that will help you in your theme coding process, seriously reducing your development time.
If you want to spend more time in designing Wodpress themes, for sure you’ll need a framework to eliminate some of the repetitive code. Most of the frameworks presented here are HTML5 and use responsive design so my recommendation is to try these first. The best part of using a framework is the support that you can have via communities built around, also the optimization for HTML, CSS, PHP and mobile devices (not all of them). Don’t waste time and give a shot to these amazing open source frameworks and transform your website into something fantastic.
In this article you’ll find some of the best WordPress frameworks and started themes that will ease your work process. Try a few of them, I recommend the responsive ones because they’ll be a standard in the near future, and then decide which one will choose for your future projects.
