# --description--
|
|
|
|
Every `region` role requires a visible label, which should be referenced by the `aria-labelledby` attribute.
|
|
|
|
To the `section` elements, give the following `aria-labelledby` attributes:
|
|
|
|
- `student-info`
|
|
- `html-questions`
|
|
- `css-questions`
|
|
|
|
Then, within each `section` element, nest one `h2` element with an `id` matching the corresponding `aria-labelledby` attribute. Give each `h2` suitable text content.
|
|
|
|
# --hints--
|
|
|
|
You should give the first `section` element an `aria-labelledby` attribute of `student-info`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('section')?.[0]?.getAttribute('aria-labelledby'), 'student-info');
|
|
```
|
|
|
|
You should give the second `section` element an `aria-labelledby` attribute of `html-questions`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('section')?.[1]?.getAttribute('aria-labelledby'), 'html-questions');
|
|
```
|
|
|
|
You should give the third `section` element an `aria-labelledby` attribute of `css-questions`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('section')?.[2]?.getAttribute('aria-labelledby'), 'css-questions');
|
|
```
|
|
|
|
You should nest one `h2` element within the first `section` element.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('section')?.[0]?.querySelectorAll('h2')?.length, 1);
|
|
```
|
|
|
|
You should nest one `h2` element within the second `section` element.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('section')?.[1]?.querySelectorAll('h2')?.length, 1);
|
|
```
|
|
|
|
You should nest one `h2` element within the third `section` element.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('section')?.[2]?.querySelectorAll('h2')?.length, 1);
|
|
```
|
|
|
|
You should give the first `h2` element an `id` attribute of `student-info`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('h2')?.[0]?.id, 'student-info');
|
|
```
|
|
|
|
You should give the second `h2` element an `id` attribute of `html-questions`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('h2')?.[1]?.id, 'html-questions');
|
|
```
|
|
|
|
You should give the third `h2` element an `id` attribute of `css-questions`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('h2')?.[2]?.id, 'css-questions');
|
|
```
|
|
|
|
You should give the first `h2` element suitable text content. _Hint: I would have chosen `Student Info`_
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('h2')?.[0]?.textContent?.length, 1);
|
|
```
|
|
|
|
You should give the second `h2` element suitable text content. _Hint: I would have chosen `HTML`_
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('h2')?.[1]?.textContent?.length, 1);
|
|
```
|
|
|
|
You should give the third `h2` element suitable text content. _Hint: I would have chosen `CSS`_
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('h2')?.[2]?.textContent?.length, 1);
|
|
```
