When I resize my browser window, larger than 480px, I get a thin block of white above my green header on the About page.

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: 28.3333%; }

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

/****************************** PAGE: ABOUT ******************************/

.profile-photo { float: left; margin: 0 5% 80px 0; }

}

@media screen and (min-width: 660px) {

/****************************** HEADER ******************************/

nav { background: none; float: right; font-size: 1.125em; margin-right: 5%; text-align: right; width: 45%; }

#logo { float: left; margin-left: 5%; text-align: left; width: 45%; }

h1 { font-size: 2.5em; }

h2 { font-size: 0.825em; margin-bottom: 20px; }

header { border-bottom: 5px solid #599a68; margin-bottom: 60px; }

}

have you tried setting your body margins to 0?

body { margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px }

I have not. Would I set that in responsive.css or main.css?

you have 2 seperate css sheets? i would do it in whatever you are using in your "default" load state.. so in a mobile first setting i would set it there. but there is no real harm in invoking it in both places. just copy and paste it.

A good practice is to use CSS resets to ensure that you are ensuring that you are setting the browser to a zero state. Each browser renders slightly differently and can sometimes produce side effects. I would recommend using Normalize (https://necolas.github.io/normalize.css/) to help you ensure that this isn't being caused by how the browser is rendering. This would effectively implement what Blake is recommending with the body margins being set to 0, but for all aspects of your styling and markup.
