Problem changing the Header text color depending on the width of the browser.

So I input the code just as the video instructed and no matter what dimensions i put the browser in to i can't get the text to change color. I can't seem to figure out what i'm missing after troubleshooting for a while now.

        @media screen and (min-width: 600px) and (max-width: 800px) {
    header {
        color: yellow;
    }
}

Your code works in my browsers. Do you have syntax errors earlier in the CSS file?

These are the 2 areas it says there are errors when run it through the validator. I'm not sure if either of these would cause the problem.

 #interesting-banner {
    position: sticky;
    z-index: 3;
    top: 0;
    padding: 10px 15px;
    border: 12px solid lightsalmon;
    margin 0 -8px;
    background: firebrick;
    color: white;
    font-weight: bold;
} 

    @media screen and (min-width: 600px) and (max-width: 800px) {
        header {
            color: yellow;
        }
    }
@media screen and (min-width: 730px) {
        ul li {
            display: inline-block;
            width: 30%;
        }
    }

To fix the first error, you could change margin 0 -8px; to margin: 0 -8px;, but it doesn't cause the problem.

I'm not seeing a syntax error when I run the second set of code through a validator. What code do you have right before it, and do you see the result from the second media query when the dimensions are large enough?

I figured it out finally, I had not completely deleted my previous media query for screen dimensions and that one was taking priority without there being an actual error, Thanks for the help though!
