Attribut de nom HTML <meta>
Exemple
Utilisez l'attribut name pour définir une description, des mots clés et l'auteur d'un document HTML. Définissez également la fenêtre d'affichage pour contrôler les dimensions et la mise à l'échelle de la page pour différents appareils :
<head>
<meta name="description" content="Free Web tutorials">
<meta name="keywords" content="HTML,CSS,JavaScript">
<meta name="author" content="John Doe">
<meta
name="viewport" content="width=device-width, initial-scale=1.0">
</head>
L' nameattribut spécifie le nom des métadonnées.
L' nameattribut spécifie un nom pour l'information/la valeur de l'
contentattribut.
Remarque : Si l' http-equivattribut est défini, l'
nameattribut ne doit pas l'être.
HTML5 a introduit une méthode permettant aux concepteurs Web de prendre le contrôle de la fenêtre d'affichage (la zone visible par l'utilisateur d'une page Web), via la
<meta>balise (voir l'exemple "Configuration de la fenêtre d'affichage" ci-dessous).

Valeurs d'attribut
| Value | Description |
|---|---|
| application-name | Specifies the name of the Web application that the page represents |
| author | Specifies the name of the author of the document. Example:
<meta name="author" content="John Doe">
|
| description | Specifies a description of the page. Search engines can pick up this description to show with the results of searches. Example:
<meta name="description" content="Free web tutorials">
|
| generator | Specifies one of the software packages used to generate the document (not used on hand-authored pages). Example:
<meta name="generator" content="FrontPage 4.0">
|
| keywords | Specifies a comma-separated list of keywords - relevant to the page (Informs search engines what the page is about). Tip: Always specify keywords (needed by search engines to catalogize the page). Example:
<meta name="keywords" content="HTML, meta tag, tag reference">
|
| viewport | Controls the viewport (the user's visible area of a web page). The viewport varies with the device, and will be smaller on a mobile phone than on a computer screen. You should include the following <meta> viewport element in all your web pages:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
A <meta> viewport element gives the browser instructions on how to control the page's dimensions and scaling. The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device). The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser. Here is an example of a web page without the viewport meta tag, and the same web page with the viewport meta tag: Tip: If you are browsing this page with a phone or a tablet, you can click on the two links below to see the difference.
