Html stylesheet meta tag

HTML Tag

The tag defines metadata about an HTML document. Metadata is data (information) about data.

tags always go inside the element, and are typically used to specify character set, page description, keywords, author of the document, and viewport settings.

Metadata will not be displayed on the page, but is machine parsable.

Metadata is used by browsers (how to display content or reload page), search engines (keywords), and other web services.

There is a method to let web designers take control over the viewport (the user’s visible area of a web page), through the tag (See «Setting The Viewport» example below).

HTML — The Head Element

The HTML element is a container for the following elements: , , , , , and .

The HTML Element

The element is a container for metadata (data about data) and is placed between the tag and the tag.

HTML metadata is data about the HTML document. Metadata is not displayed.

Metadata typically define the document title, character set, styles, scripts, and other meta information.

The HTML Element

The element defines the title of the document. The title must be text-only, and it is shown in the browser’s title bar or in the page’s tab.

The element is required in HTML documents!

The content of a page title is very important for search engine optimization (SEO)! The page title is used by search engine algorithms to decide the order when listing pages in search results.

• defines a title in the browser toolbar
• provides a title for the page when it is added to favorites
• displays a title for the page in search engine-results

So, try to make the title as accurate and meaningful as possible!

Setting the viewport to make your website look good on all devices:

Example

Setting The Viewport

The viewport is the user’s visible area of a web page. It varies with the device — it will be smaller on a mobile phone than on a computer screen.

You should include the following element in all your web pages:

This 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:
