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 -->.
Here is an example of a comment with the TODO: Remove h1:
<!-- TODO: Remove h1 -->
Add a comment above the p element with this text:
TODO: Add link to cat photos
Your comment should start with <!--. You are missing one or more of the characters that define the start of a comment.
assert.match(code, /<!--/);
Your comment should end with -->. You are missing one or more of the characters that define the end of a comment.
assert.match(code, /-->/);
Your code should not have extra opening/closing comment characters. You have an extra <!-- or --> displaying in the browser.
const noSpaces = code.replace(/\s/g, '');
assert.isBelow(noSpaces.match(/<!--/g)?.length, 2)
assert.isBelow(noSpaces.match(/-->/g)?.length, 2);
Your comment should be above the p element. You have them in the wrong order.
assert.match(
code.replace(/\s/g, ''),
/<!--(.*?)--><p>everyonelovescutecatsonline!<\/p>/i
);
Your comment should contain the text TODO: Add link to cat photos.
assert.match(code, /<!--\s*todo:\s+add\s+link\s+to\s+cat\s+photos\s*-->/i);
