Okay, here's a few hints:

  • you need to make a new rule
  • you're styling images, so you probably want the rule's selector to target the IMG element tag
  • the property to cause something to expand but still be flexible is max-width
  • since you don't know the size of the parent, you may want to specify the value as a percentage

I'm betting you can get it now without an explicit spoiler.

I'm also on this and I have no idea what is going on. I'm really struggling to understand a lot of this CSS and feeling very demotivated to continue.

I don't even know what this question is asking me to do.

Nick will have mentioned it in a previous video, the best thing I recommend is to go back to the previous ones and have a quick recap. Did you follow along on workspaces? If so the answer may already be in your css file :)

By 'fill their parent element' it means that the image will want to go as big as the element they are contained in.

For example

<div>
  <img src="someimage.jpg" />
</div>

The 'parent' of the img element is the div element. So if the image is naturally 300x300px and the div is 400x400px, if the image is at 100% of its size as a maximum, it will try to fill out the div. But if the div was resized to say 200x200px, if you set a certain css property on your img, it WILL go smaller as the div containing it shrinks.

Don't be discouraged, keep going and remember a website wasn't built in a day (or was that Rome? Hmm...)
