implementing media queries in the responsive website project

Hi, I am working on implementing media queries in the responsive website project. I have typed the code the Allison used to make the navigation scale with the "contact us" on the next row down. When I refresh my browser, it doesn't change on my page. Does anyone know what I'm doing wrong?

/* media queries */
/* iphone--------------- */
@media screen and (max-width: 480px) {
.grid_1,
.grid_2,
.grid_3,
.grid_4,
.grid_5,
.grid_6,
.grid_7,
.grid_8,
.grid_9,
.grid_10,
.grid_11,
.grid_12 {
    width: 100%;
}
#nav ul {
    margin: 5% 0;
}

#nav ul li {
float: left;
margin: 5% 0;
}
#nav ul li.about {
    width: 20%;
}    
#nav ul li.pricing {
    width: 50%;
}
#nav ul li.locations {
    width: 30%;
}
#nav ul li.contact {
    width: 100%;
    margin: 0;
    font-size: 1em;

You forgot to close 2 of your curly brackets. I've reformatted your CSS, see if you can spot where they are missing. Using a text editor with bracket matching can help you spot such things.

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

.grid_1,
.grid_2,
.grid_3,
.grid_4,
.grid_5,
.grid_6,
.grid_7,
.grid_8,
.grid_9,
.grid_10,
.grid_11,
.grid_12 { width: 100%; }

#nav ul { margin: 5% 0; }
#nav ul li {
    float: left;
    margin: 5% 0;
}

#nav ul li.about { width: 20%; }    
#nav ul li.pricing { width: 50%; }
#nav ul li.locations { width: 30%; }
#nav ul li.contact {
    width: 100%;
    margin: 0;
    font-size: 1em;

Hi James, Thanks for your response. It looks like I am missing the closing curly bracket for the "contact" line and missing the closing curly bracket for the entire media query. I added those in and I'm still not seeing the changes in my page. I updated the formatting to what you suggested above, and added in the two brackets that I saw were missing.

@media screen and (max-width: 480px) {
    .grid_1,
    .grid_2,
    .grid_3,
    .grid_4,
    .grid_5,
    .grid_6,
    .grid_7,
    .grid_8,
    .grid_9,
    .grid_10,
    .grid_11,
    .grid_12 {width: 100%;}

#nav ul {margin: 5% 0;}

#nav ul li a {
    -webkit-user-select: none;
}

#nav ul li {
float: left;
margin: 5% 0;
}

#nav ul li.about { width: 20%; }    
#nav ul li.pricing { width: 50%; }
#nav ul li.locations { width: 30%; }
#nav ul li.contact {
    width: 100%;
    margin: 0;
    font-size: 1em;}
}

Make sure that you downloaded the directory for that lesson, because it does not include the same index.html file that was used in the original Build a Simple Website directory. It has a lot of changes in the markup. I made that mistake and kept thinking there was an error in my CSS.
