Hey Kevin,

I'm not sure why you are putting so many rules into the img tag, but you are way overthinking this one.

All the challenge wants is one rule that will allow it to fill the parent element. You do have to rule in there, just not with the right value, and the rest of the rules need to be deleted, because the challenge did not ask for any of them.

Because you pretty much have it, I will give the corrected rule, so you can see what I mean... and remember, challenges are very specific and very picky. If it didn't ask you to do something... don't. Because it will often result in a Bummer!

/* Task One: */

img {
  max-width: 100%;
}

max-width is just that. Fill to the maximum width available inside the parent. 100% means to the full width of the parent. 50% would mean only half the width of the parent... etc.

I hope this helps to make sense.

Keep Coding! :) :dizzy:

Thanks Jason for answering both of my questions! By any chance could you tell me what "parent element" means. Also I was stuck for quite long so I just started adding in CSS from my actual project that explains why there was list-style: none; float: left; width:45%;

A parent element is what is enclosing the element you are specifying (also know now as the child element). So if you have

<div>
  <img src ......... >
</div>

The <div> is the parent and the <img> is the child. As you nest further, you can develop even more 'relationships', but leaning all this will come soon enough. I don't want to confuse you with terms and relations that you haven't been introduced to just yet, but you will soon! :smile:
