I’ve just been in the process of modifying an existing website to work a bit better on mobiles / tablets. The site in question already had a responsive design, being based on the WordPress 2012 theme, but I wasn’t quite happy with exactly how it was displaying.
There were a few websites that proved quite helpful in helping me getting things working as I wanted. I’d like to share them here so I have a reference for similar problems in the future, and if you’re reading this, you may find them helpful too.
