HTML meta: Main Tips
- With
metatags, HTML metadata can be defined. - In Greek, meta means beyond. Thus, metadata is not displayed on the web page: it is only parsable by the machine.
- Using the
metatag, keywords, descriptions, and other information can be specified for the page. - HTML
metatags must be placed inside the <head> element. - You can use one or multiple
metatags in one document.
Using HTML meta Tags
The content between HTML meta tags is supplementary information about a website which is not displayed in the page:
<head>
<meta charset="UTF-8">
<meta name="description" content="Learn to code!">
<meta name="keywords" content="HTML, PHP, JavaScript">
<meta name="author" content="The BitDegree Team">
</head>Metadata is useful in search engine optimization (SEO). Search engines use meta keywords to gather information about the content your website offers its users.
Note: you can also set the viewport using your meta tags to control the visible page areas. However, not every browser supports that.
Theory is great, but we recommend digging deeper!
Tag-specific Attributes for <meta>
charset sets the character encoding for the webpage:
<meta charset="UTF-8">Tip: defining character encoding helps prevent cross-scripting attacks. You should use UTF-8 or another ASCII-compatible encoding.
name sets a name for the metadata (e.g., meta keywords, author, etc.):
<meta name="description" content="Learn to code">http-equiv defines a pragma directive. All the possible values have the same names as certain HTTP headers (i.e., content-security-policy or refresh), hence the name:
<meta http-equiv="refresh" content="30">content defines the value for the name or http-equiv attribute:
<meta name="description" content="Learn to code">
<meta name="keywords" content="HTML, HTML Meta Tag">scheme used to set the context in which the value of the content attribute should have been interpreted (a format):
<meta name="date" content="2019-08-04" scheme="YYYY-MM-DD">Note: the scheme attribute has been made obsolete in HTML5.
