In the JavaScript and the DOM challenge the instructions suggest using a DESCENDANT SELECTOR but no access to .css.

What am I not seeing here????

There is also a suggestion to use querySelectorAll. Here is the MDN page where you will see under syntax:

selectors A DOMString containing one or more selectors to match against. This string must be a valid CSS selector string;

So the selector works the same as it would in a CSS file

I find this exercise confusing too; I'm in the middle of solving an exercise and first link goes to a video to learn a new topic - that doesn't even seem to be of any help?

I'd suggest they remove the video link and keep the second "descendants of an element" link to avoid unnecessary confusion.

Maybe a CSS course should be a prerequisite for this course as well. In fact I didn't find any prerequisites at all listed for this course, it seems like they missed that?
