Using Chrome to create AdBlock/UBlock rules

I want to lea how to use Chrome devtools to create my own custom adblocking rules according to Ublock/Adblock syntax. Now before I do that I need to figure out how Chrome's dev tools work.

Observe the picture please. This entire div element is what I want to block. Unfortunately this div element comes with an id. Said id is a random salad of numbers and letters that change everytime you reload the page.

How can I figure out what the "id" is actually called so that I can create a block rule just for that specific id with that specific name?

Bonuspoints if you can show me how to create the rule :P
