Reset/remove CSS styles for element only

Question

I\'m sure this must have been mentioned/asked before but have been searching for an age with no luck, my terminology must be wrong!

I vaguely remember a twee

You mentioned mobile-first sites... For a responsive design, it's certainly possible to override small-screen styles with large-screen styles. But you might not need to.

Try this:

.thisClass {
    /* Rules for all window sizes. */
}

@media all and (max-width: 480px) {
    .thisClass {
        /* Rules for only small browser windows. */
    }
}

@media all and (min-width: 481px) and (max-width: 960px) {
    .thisClass {
        /* Rules for only medium browser windows. */
    }
}

@media all and (min-width: 961px) {
    .thisClass {
        /* Rules for only large browser windows. */
    }
}

Those media queries don't overlap, so their rules don't override each other. This makes it easier to maintain each set of styles separately.
