Diagonal hover effect

Hi, I am so excited about using this theme again. So many new features and still so easy to use and customise. Thank you Niko!

One question. I would like to apply this diagonal slider hover effect shown in the demo:

Can you please tell me how to apply it. Is it a setting? If not could you show me the code please?

Many Thanks
