New design of Screener

The new design organises the content into "cards". It makes things easier to find and scan. Plus we made a lot of changes to make the pages more friendly on mobiles and tablets.

We have also changed the font to make it more readable. It works particularly well on small devices. We have also added a new "dark mode" which is easier on eyes during night.

The new design focuses on organisation and simplicity. It also gives us some space to add new content in future 😉. 

Thanks to Vishnu for the brilliant design work.
