/*  I got tired of having to scroll all the way down to get to the "Show less" button,
   so I made this. It lets you collapse the description box by clicking the right half
   of it. The button lights up when hovering over it. If there are any links where the
   button is, they will still be clickable. It also allows you to select any text that
   might be on top of where the button is. */
