<meta> setting view port
HTML5 introduced a method to let web designers take control over the viewport, through the <meta> tag. The viewport is the user's visible area of a web page. It 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: EX <meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta> notes
Note: <meta> tags always go inside the <head> element. Note: Metadata is always passed as name/value pairs. Note: The content attribute MUST be defined if the name or the http-equiv attribute is defined. If none of these are defined, the content attribute CANNOT be defined
http-equiv
Provides an HTTP header for the information/value of the content attribute values content-type default-style refresh
vh
Relative to 1% of the height of the viewport*
vw
Relative to 1% of the width of the viewport*
vmax
Relative to 1% of viewport's* larger dimension
vmin
Relative to 1% of viewport's* smaller dimension
name
Specifies a name for the metadata values application-name author description generator keywords viewport
character_set
Specifies the character encoding for the HTML document
<meta>
The <meta> tag provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine parsable. Meta elements are typically used to specify page description, keywords, author of the document, last modified, and other metadata. The metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services.
