How do <scripts> load inside of comment tags?

The following code is in head section of a page:

<!--[if lt IE 9]>
    <script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>
    <script src="https://oss.maxcdn.com/libs/respond.js/1.4.2/respond.min.js"></script>
<![endif]-->

Shouldn't the comment tags stop this script from being run?

Solution

  • It's called Conditional Comments
