HTML: Here’s a brief explanation of :

Document Type Declaration: It tells the browser that the document is written in HTML5, the latest version of HTML.
Standards Mode: It ensures that the document is rendered using the web standards for HTML and CSS. This prevents the browser from reverting to "quirks mode," which attempts to render the page in a way that is compatible with older browsers but can lead to inconsistent behavior.
