I came across this website, with the Angular theme, that had some features that I can't seem to directly find:
1. When you click on a portfolio item on the home page, it displays an alternate picture, which I quite like.
2. The other is that when you click on an item the coloured state remains (this isn't so important), and I can probally fix this. Number 1 is most important. Does anyone know how to do this? Does this require editing core files?
