I don't know how to write the corect code for this requirement:"Inside the media query, clear the left side of every 4th list item in the gallery." Thank you, if you can explain me.

Hello there,

This refers to the nth-child pseudo-selector which is pretty handy!

Here is an example of using it:

'''

my_id ul li:nth-child(3n) {

color: #ccc; } '''

What the above CSS does, is select every third list item inside unordered lists inside an id called my_id. That is, the 3rd, 6th, 9th, 12th, etc.

Thank you so much! Was very userfull what you explain me!

My pleasure. :)
