# --description--
Give each `th` element a `span` element with the class set to `sr-only` and the following text, in order: `2019`, `2020`, and `2021`.
# --hints--
Each of your `th` elements should have a `span` element.
```js
const ths = [...document.querySelectorAll('table')?.[1]?.querySelectorAll('th')];
ths?.forEach(th => {
assert(th?.children?.length === 1);
assert(th?.children?.[0]?.localName === 'span');
});
```
Each of your new `span` elements should have the `class` attribute set to `sr-only`.
```js
const ths = [...document.querySelectorAll('table')?.[1]?.querySelectorAll('th')];
ths?.forEach(th => {
assert(th?.children?.[0]?.classList?.contains('sr-only'));
});
```
Your first `span` element should have the text `2019`.
```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('th')?.[0]?.children?.[0]?.textContent === '2019');
```
Your second `span` element should have the text `2020`.
```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('th')?.[1]?.children?.[0]?.textContent === '2020');
```
Your third `span` element should have the text `2021`.
```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('th')?.[2]?.children?.[0]?.textContent === '2021');
```
Your `td` element should be empty.
```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('td')?.[0]?.textContent === '');
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('td')?.[0]?.children?.length === 0);
```
