META Description
<meta name="keywords" content="HTML, CSS, JavaScript"> <meta name="author" content= "Web desigining">
The <meta> tag defines metadata about an HTML document. Metadata is data (information) about data. The <meta> tag also supports the Global Attributes in HTML.
<meta> tags always go inside the <head> element, and are typically used to specify character set, page description, keywords, author of the document, and viewport settings.
Meta elements are tags used in HTML and XHTML documents to provide structured metadata about a Web page. They are part of a web page's head section. Multiple Meta elements with different attributes can be used on the same page.
The head of an HTML document is the part that is not displayed in the web browser when the page is loaded. It contains information such as the page <title>, links to CSS (if you choose to style your HTML content with CSS), links to custom favicons, and other metadata (data about the HTML, such as the author, and important keywords that describe the document). Web browsers use information contained in the head to render the HTML document correctly.
Search engines such as Google use metadata from meta tags to understand additional information about the webpage. They can use this information for ranking purposes, to display snippets in search results, and sometimes they can ignore meta tags. Example of meta tags include the <title> and <description> elements.
