# --description--
Commenting allows you to leave messages without affecting the browser display. It also allows you to make code inactive. A comment in HTML starts with ``. For example, the comment `` contains the text `TODO: Remove h1`.
Add a comment above the `p` element with the text `TODO: Add link to cat photos`.
# --hints--
Your comment should start with ``. You are missing one or more of the characters that define the end of a comment.
```js
assert(code.match(/-->/));
```
Your code should not have extra opening/closing comment characters. You have an extra `` displaying in the browser.
```js
const noSpaces = code.replace(/\s/g, '');
assert(noSpaces.match(//g).length < 2);
```
Your comment should contain the text `TODO: Add link to cat photos`.
```js
assert(code.match(//i));
```
Your comment should be above the `p` element. You have them in the wrong order.
```js
assert(
code
.replace(/\s/g, '')
.match(
/clickheretoviewmorecatphotos\.?<\/p>/i
)
);
```
