                <!DOCTYPE html>
<title>Le doctype HTML en 1ère ligne</title>

<p>L'instruction doctype HTML est la première ligne de code du document.</p>
<p>Comme les informations renseignées dans l'élément head, "doctype HTML" est invisible à l'écran quand le navigateur ouvre la page web.</p>
<p>Grâce à la mention doctype HTML, ici, le navigateur sait qu'il doit utiliser le langage HTML5 pour interpréter le code.</p>
<p>Il n'y a pas besoin d'écrire de balise fermante pour l'instruction doctype HTML.</p>
