Change child element with a different CSS as parent element is hovered. How?

How do I change a child element and the parent element when the parent element is selected, and both are going to be assigned to different properties' values? For example:

HTML

<footer id="gameStart">
    <div>
        <p> START </p>
    </div>
</footer>

What's supposed to happen on CSS

1. If footer#gameStart is hovered, then{
    footer#gameStart background-color: #787878;
    footer div background-color: #CCCCCC;
}

If possible, a way to solve it without scripting. Thanks :)

Hi Daniel,

You can use the :hover selector.

For example:

/* default state */
footer#gameStart {  }
footer#gameStart div {  }

/* when #gameStart is hovered */
footer#gameStart:hover { background-color: #787878; }
footer#gameStart:hover div { background-color: #CCCCCC; }

It worked :) Thanks. It was so obvious, and I was never going to guess it. I thought it had something to do with the selector x:hover + y{ } Thanks you a lot! You saved me a lot of headache!

#parent:hover {
    background: green;
}

#parent:hover #child {
    background: yellow;
}

This will achieve the desired effect, there will be a DRY'er way with Js, but for vanilla CSS this will do the job.
