HTML <meta> název Atribut
Příklad
Pomocí atributu name definujte popis, klíčová slova a autora dokumentu HTML. Definujte také zobrazovanou oblast pro řízení rozměrů stránky a měřítka pro různá zařízení:
<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>
Atribut name
určuje název metadat.
Atribut name
určuje název pro informaci/hodnotu
content
atributu.
Poznámka: Pokud je http-equiv
atribut nastaven,
name
neměl by být nastaven.
HTML5 zavedlo metodu, která umožňuje webovým designérům převzít kontrolu nad viewport (uživatelova viditelná oblast webové stránky) prostřednictvím
<meta>
značky (viz příklad „Nastavení Viewportu“ níže).

application-name | Specifies the name of the Web application that the page represents |
author | Specifies the name of the author of the document. Example:

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.
