Won't change to 3 columns.

Here is my CSS code for the responsive.css:

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

/************************ TWO COLUMN LAYOUT ************************/

#primary { width:50%; float:left; }

#secondary{ width:40%; float:right; }

/* PAGE: PORTFOLIO */
#gallery li {
    width: 28.333333%;  
}

#gallery li:nth-child(4n) {
    clear:left;
}

}

It stays in 2 columns the entire time.
