# --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 `<!--`, contains any number of lines of text, and ends with `-->`. For example, the comment `<!-- TODO: Remove h1 -->` 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 start of a comment.
|
|
|
|
```js
|
|
assert(code.match(/<!--/));
|
|
```
|
|
|
|
Your comment should end 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 `<!--` or `-->` displaying in the browser.
|
|
|
|
```js
|
|
const noSpaces = code.replace(/\s/g, '');
|
|
assert(noSpaces.match(/<!--/g).length < 2 && noSpaces.match(/-->/g).length < 2);
|
|
```
|
|
|
|
Your comment should contain the text `TODO: Add link to cat photos`.
|
|
|
|
```js
|
|
assert(code.match(/<!--\s*todo:\s+add\s+link\s+to\s+cat\s+photos\s*-->/i));
|
|
```
|
|
|
|
Your comment should be above the `p` element. You have them in the wrong order.
|
|
|
|
```js
|
|
assert(
|
|
code
|
|
.replace(/\s/g, '')
|
|
.match(
|
|
/<!--todo:addlinktocatphotos--><p>clickheretoviewmorecatphotos\.?<\/p>/i
|
|
)
|
|
);
|
|
```
