# --description--
|
|
|
|
Create a media query for screens smaller than `800px` in width. In that media query, create a `#gallery img` rule and set the `width` property to `50%`. This will convert your gallery to a two-column layout.
|
|
|
|
# --hints--
|
|
|
|
You should add a new `@media` query.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('media')?.length === 1);
|
|
```
|
|
|
|
Your new `@media` query should have a `max-width` of `800px`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('media')?.[0]?.media?.mediaText === '(max-width: 800px)');
|
|
```
|
|
|
|
Your `@media` query should have a `#gallery img` rule.
|
|
|
|
```js
|
|
const rules = new __helpers.CSSHelp(document).getRuleListsWithinMedia('(max-width: 800px)');
|
|
assert(rules?.find(rule => rule.selectorText === '#gallery img'));
|
|
```
|
|
|
|
Your `#gallery img` rule should have a `width` property set to `50%`.
|
|
|
|
```js
|
|
const rules = new __helpers.CSSHelp(document).getRuleListsWithinMedia('(max-width: 800px)');
|
|
const imgRule = rules?.find(rule => rule.selectorText === '#gallery img');
|
|
assert(imgRule?.style.width === '50%');
|
|
```
