HTML How to Make a Website Responsive Web Design and Testing Refactor the Layout

For Challenge 1 under Web design, Build a Three column layout

No idea what I'm doing wrong. I wrote the code exactly as Nick says, but something is wrong. Has anyone else had this problem on this question? I'm sorry but I cannot understand much at this point, so bear with me. This is what I have written

@media screen and (min-width: 480px) {

gallery li {

width: 28.3333%; } } I've tried typing it in different sections of the code on the challenge page, messing with the spacing between the colons and semi-colons etc. Something's not right and I can't figure it out.

Thanks! It appears I am not alone in this.
