The head Element HTML5

The next part of our page is the <head> section. The first line inside the head is the
one that defines the character encoding for the document. This is another element
that’s been simplified. Here’s how you used to do this:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
HTML5 improves on this by reducing the character encoding <meta> tag to the bare
minimum:
<meta charset="utf-8">

In nearly all cases, utf-8 is the value you’ll be using in your documents.
