How does the browser know what language other documents are written in? For example, why doesn’t css need a doctype?

Thanks for the explanation.

In HTML, the document structure typically starts with the <!DOCTYPE> declaration followed by the <html> tag. Here’s a breakdown of these and other common tags used to start HTML documents:

  1. <!DOCTYPE>: This is not technically an HTML tag, but rather a document type declaration that specifies which version of HTML (or XHTML) the document is using. It informs the web browser about the version of HTML being used and helps it render the document correctly.
  2. <html>: This tag wraps the entire HTML document and serves as the root element. All other elements in the document are descendants of this element. It contains two main sections: <head> and <body>.
  3. <head>: This section contains meta-information about the HTML document, such as the document title, character encoding, stylesheets, scripts, and other metadata. It’s not displayed on the web page itself but provides essential information to the browser and search engines.
  4. <body>: This section contains the main content of the HTML document, including text, images, links, forms, and other elements that are visible to the user. It’s the part of the document that is rendered and displayed in the web browser window.

These are the primary tags used to start an HTML document. Additionally, you may encounter other tags within the <head> section for specific purposes, such as:

  • <title>: Defines the title of the HTML document, which appears in the browser’s title bar or tab.
  • <meta>: Provides metadata about the HTML document, such as character encoding, viewport settings, authorship, and keywords for search engines.
  • <link>: Links external resources, such as stylesheets (CSS) or icon files, to the HTML document.
  • <script>: Embeds or links to JavaScript code that enhances the functionality or behavior of the HTML document.

Are there other types of DOCTYPEs that you can use in a browser?
