--description--

Within the @media query, add a .keys selector and set the width to 318px.

--hints--

Your @media rule should have a .keys selector.

const rules = new __helpers.CSSHelp(document).getRuleListsWithinMedia('(max-width: 768px)');
const keys = rules?.find(rule => rule.selectorText === '.keys');
assert(keys);

Your new .keys selector should have a width of 318px.

const rules = new __helpers.CSSHelp(document).getRuleListsWithinMedia('(max-width: 768px)');
const keys = rules?.find(rule => rule.selectorText === '.keys');
assert(keys?.style.width === '318px');
