Media Queries Min-Width Question

Hi

I'm having trouble with media queries I'm attempting to write.

At a screen and min-width of 150px wide why does my .secondary-content h3 appear at a tomato color (as my browser is longer than 150px)?

I thought as I shrunk the browser down to min-width of 150px at that point my background color will appear tomato red? my syntax is below. What am I doing wrong?

/* Page Styles
================================ */

@media screen and (min-width: 150px){
    .secondary-content h3 {
        background-color: tomato;
    }
}

* {
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}
body {
    font: normal 1.1em/1.5 sans-serif;
    color: #222;
    background-color: #edeff0;
}

/*.main-wrapper {
    width: 90%;
    margin: auto;
}
*/

/* Layout Element Colors
================================ */

.main-header       { background-color: #384047; }
.main-logo a       { background-color: #5fcf80; }
.main-nav a        { background-color: #3f8abf; }
.primary-content   { background-color: #caebf6; }
.secondary-content { background-color: #bfe3d0; }
.main-footer       { background-color: #b7c0c7; }

I think you are expecting what max-width would do. By setting min-width you will make all screen widths above 150 pixels have the tomato background color on your .secondary-content h3. If you change it to max-width then only when you have a screen width below 150 pixels will that background then change to tomato. Try changing min-width to max-width and see if that is what you are looking for. Hope that helps.
