Description

When we start using jQuery, we will modify HTML elements without needing to actually change them in HTML. Let's make sure that everyone knows they shouldn't actually modify any of this code directly. Remember that you can start a comment with  Add a comment at the top of your HTML that says Only change code above this line.

Instructions

Tests

tests:
  - text: 'Start a comment with <code>&#60;!--</code> at the top of your HTML.'
    testString: 'assert(code.match(/^\s*<!--/), "Start a comment with <code>&#60;!--</code> at the top of your HTML.");'
  - text: Your comment should have the text <code>Only change code above this line</code>.
    testString: 'assert(code.match(/<!--(?!(>|->|.*-->.*this line))\s*.*this line.*\s*-->/gi), "Your comment should have the text <code>Only change code above this line</code>.");'
  - text: 'Be sure to close your comment with <code>--&#62;</code>.'
    testString: 'assert(code.match(/-->.*\n+.+/g), "Be sure to close your comment with <code>--&#62;</code>.");'
  - text: You should have the same number of comment openers and closers.
    testString: 'assert(code.match(/<!--/g).length === code.match(/-->/g).length, "You should have the same number of comment openers and closers.");'
