Another problem. Unable to clear 4th item. It does not fix the problem on mobile

Please check what is wrong in the coding as it is not clearing the 4th item. The problem remains on mobile.

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

#primary { 

    width: 50%; float: left; }



#secondary { 

    width: 40%; float: right; }

/************************** 3 * 15 = 15% 100% - 15% = 85% 85 / 3 = 28.3333333333 **************************/

/************************** PAGE: IMAGE PAGE **************************/

gallery li {

width:28.3333%;

}

gallery li:nth-child(4n) {

clear: left;

}

}

Do you have more than 6 items? There's a comment in the teacher's notes explaining that :nth-child(3n + 1) should be used instead of what is shown in the video.
