Ok, well you need to create a selector that targets that image tags, and makes sure that only img tags with an attribute of type title with the value avatar are selected.

Here is how we write a selector that targets the attributes of a specific tag (in this case the img tag), notice the square brackets, this denotes that the selector should be looking for the specified html tag with an attribute.

img[] {
}

Now we need to specify which attribute it is, we do this by typing the attribute within the square brackets:

img[title] {
}

But we aren't done yet, we also need to make sure that the value of the attribute is specifically 'avatar' so let's doe that now.

img[title="avatar"] {
}

Finally we add the styles for the border radius

img[title="avatar"] {
    border-radius: 50%;
}

I advise that you go back and rewatch the videos for better understanding.

Hi Joshua, Attribute selectors work like this:

selector[attribute="value"] {
     property: value;
}

So in your case, the selector would be img and your attribute would be title (referencing the image tag below).

<img src="avatar.png" title="avatar" alt="">
