Logical operators can be used to construct more complex media queries. The and logical operator is used to query two media conditions.

For example, a media query that targets a display width between 500px and 1000px would be:

@media (min-width: 500px) and (max-width: 1000px){

}

Add another @media rule to apply if the browser window is wider than 769px but smaller than 1199px.

--hints--

You should add a new @media query.

assert(new __helpers.CSSHelp(document).getCSSRules('media')?.length === 2);

Your @media query should have a min-width of 769px and a max-width of 1199px.

const mediaText = new __helpers.CSSHelp(document).getCSSRules('media')[1]?.media?.mediaText;
assert(mediaText === '(max-width: 1199px) and (min-width: 769px)' || mediaText === '(min-width: 769px) and (max-width: 1199px)');
