|
Resize the preview to see the layout change from your media query.
|
||
|
|
|
||
|
|
Finally, create another media query for screens smaller than `600px` wide. In that media query, create a `#gallery img` rule and set the `width` property to `100%`. This will give your gallery a single-column layout.
|
||
|
|
|
||
|
|
Your CSS Flexbox Photo Gallery is now complete.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
You should have a second `@media` query.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('media')?.length === 2);
|
||
|
|
```
|
||
|
|
|
||
|
|
Your new `@media` query should come after your existing one.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('media')?.[0]?.media?.mediaText === '(max-width: 800px)');
|
||
|
|
```
|
||
|
|
|
||
|
|
Your new `@media` query should have a `max-width` of `600px`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('media')?.[1]?.media?.mediaText === '(max-width: 600px)');
|
||
|
|
```
|
||
|
|
|
||
|
|
Your new `@media` query should have a `#gallery img` selector.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const rules = new __helpers.CSSHelp(document).getRuleListsWithinMedia('(max-width: 600px)');
|
||
|
|
assert(rules?.find(rule => rule?.selectorText === '#gallery img'));
|
||
|
|
```
|
||
|
|
|
||
|
|
Your `#gallery img` rule should have a `width` property set to `100%`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const rules = new __helpers.CSSHelp(document).getRuleListsWithinMedia('(max-width: 600px)');
|
||
|
|
const imgRule = rules?.find(rule => rule?.selectorText === '#gallery img');
|
||
|
|
assert(imgRule?.style?.width === '100%');
|
||
|
|
```
