    Study Notes

    Introduction to HTML

    • HTML stands for Hypertext Markup Language and is used to define and process website content.
    • HTML is a tag-based language that has evolved from its creation by Tim Berners-Lee in 1991.
    • HTML is supported by most web browsers like Chrome, Firefox, Internet Explorer, Safari, and many others.
    • The first web page was displayed by Tim Berners-Lee at CERN.
    • The original web site of the "WWW Project" is accessible at CERN: http://info.cern.ch/hypertext/WWW/TheProject.html.
    • HTML was initially created at CERN to share research more efficiently than journal publications.
    • HTML allows users to define text formatting, image display, graphic pointers, file linkages with digital media, and forms for capturing information from users.

    HTML Elements, Tags, and Attributes

    • An HTML file is made up of Elements, Tags, and Attributes.
    • An HTML Element is the fundamental node that adds meaning to a webpage. Elements can either be self-closing (without content) or have start and end tags (with content).
    • HTML Tags are the element names surrounded by angle brackets. The end tag is signified by a slash after the opening bracket (mandatory in HTML5).
    • HTML Attributes are properties defined inside the start tag, which regulate element behavior, properties, or provide metadata.

    HTML Versions

    • HTML has gone through various versions, including HTML, HTML 2.0, HTML 3.2, HTML 4.01, and HTML5.
    • HTML5 is the latest version and was released as a recommendation in 2014.
    • The latest HTML specifications are available at:
    • The W3C and WHATWG are now collaboratively working on HTML specifications, with the W3C no longer publishing separate specifications.

    General HTML Structure

    • HTML documents are organized with a head and a body.
    • The head section contains the title and other metadata, while the body section contains the page content such as paragraphs.
    • HTML documents should begin with a line specifying the HTML version for conformance.

    Web Browsers

    • Browsers are tolerant of HTML errors and can ignore markup they don't understand.
    • Popular browsers, like Edge, Safari, Firefox, and Chrome, do not strictly require the HTML document to have and tags.
    • However, it is recommended to use these tags, and there's no assurance that all future browsers will maintain this relaxed behavior.

    Browser Tolerance Examples

    • Browsers can parse and display HTML code even when it's incorrectly formatted or missing tags.
    • Text placed between <HEAD> tags is typically not displayed.

    HTML Elements and Comments

    • Each HTML element consists of a start tag, content (optional), and an end tag (optional).
    • HTML comments can be used to provide explanations or temporarily remove code.
    • Comments cannot be nested, and whitespace is only permitted between the -- and the closing angle bracket of a comment.
    • Comments are not displayed in the final web page.

    HTML Attributes

    • The BODY tag has various attributes, including:
      • id: assigns a unique name to the element.
      • class: assigns one or more names to the element.
      • lang: specifies the language code of the natural language being used.
      • title: provides a brief description of the body content.
      • style: defines inline display information.
      • bgcolor: sets the background color.
    • The BODY tag also includes several event attributes like:
      • onload, onunload, onclick, ondblclick, onmousedown, onmouseup, onmouseover, onmousemove, onmouseout, onkeypress, onkeydown, onkeyup.
    • Deprecated attributes for the body tag include:
      • background, text, link, vlink, alink.

    Using Style Sheets

    • Style sheets are used to define the visual appearance of web pages and are a preferred method over using inline styles.
    • Inline styles are defined within the HTML element using the "style" attribute.
