CSS CSS Selectors Advanced Selectors :nth Pseudo-Class Challenge - Pt. 2

CSS Selectors challenge

I am stuck. Here is the question: "It looks like an <h1> made its way inside the parent body. Now our :nth-child selector no longer targets the desired combination of img child elements. Replace :nth-child with the pseudo-class that only targets a specific type of child element."

I'm confused...are they looking for something along the lines of h1 > img { }

style.css
/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img {
    float: left;
  }
  img:nth-child(3n+4) {
   clear: left;
  }
}
index.html

HI Dawn, The question is a little bit misleading I find as well.

You have to change the pseudo selector from

img:nth-child(3n+4)

to:

img:nth-of-type(3n+4)

You can read more about it here. https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-of-type

Can anyone explain what the difference is considering no other child interrupted the sequence of images?

img:nth-of-type(3n+4)
