Get your act together. I loved you for HTML and CSS, but I couldn’t use you on mobile platforms. I discovered that you were suppose to be updating so you would become mobile friendly. It made me so happy.
That was over a year ago. I have discovered an app that communicates with its desktop version AND it has a mobile version! audible gasp!
It is called SoloLearn. While they may not be as popular as you, they are way more versatile. I want to use you CodeCademy. But the majority of me actually learning code takes place at 3 AM on my phone, the day is reserved for putting it into practice.
So please update to a mobile version soon. Or add an app that isn’t outdated.
