If you want to work along with the video, start from this pen. Open that and click the “Fork” button in the bottom-right so you can get your own copy to work with.
The CSS framework I used is Milligram. I like to use it because it takes just basic HTML and makes it look nice. I don’t have to sprinkle a bunch of wacky classes around to get something that looks decent.
I talk about the ”+” selector and refer to it in the video as the “sibling selector.” More accurately, it’s the adjacent sibling selector. It only selects the UL if it is a sibling of the checked checkbox and also if the two are adjacent (meaning no elements between).
Hope you enjoy this tutorial! Tweet at me if you have questions.
