    What is HTML ?

    • HTML stands for Hyper Text Markup Language.
    • It is developed by Tim Berner’s Lee at W3C (World Wide Web Consortium).
    • It is used to create Static Web pages.
    • It is a global language i.e., it can be understood by all browsers.
    • It is a markup language.
    • It is not case-sensitive language.
    • The latest version of HTML is HTML 5
    • HTML documents are also called as web pages.
    • HTML pages can run on any browser.

    HTML Tags?

    • HTMLTags are to used to define the element where  to display, and how to display in your webpage
    • HTML markup tags are usually called HTML tags
    • HTML tags are keywords (tag names) surrounded by angle brackets like <html>
    • HTML tags normally come in pairs like <b> and </b>
    • The first tag in a pair is the start tag, the second tag is the end tag
    • The end tag is written like the start tag, with a forward slash before the tag name
    • Start and end tags are also called opening tags and closing tags
    • <tagname>content</tagname>

    HTML Elements?

    “HTML tags” and “HTML elements” are often used to describe the same thing.
    But strictly speaking, an HTML element is everything between the start tag
    and the end tag, including the tags:

    HTML Element:
    <p>This is a paragraph.</p>

    Web Browsers?

    The purpose of a web browser (such as Google Chrome, Internet Explorer,
    Firefox, Safari) is to read HTML documents and display them as web pages.
    The browser does not display the HTML tags, but uses the tags to interpret
    the content of the page.

    The <!DOCTYPE> Declaration

    The <!DOCTYPE> declaration helps the browser to display a web page correctly.
    There are many different documents on the web, and a browser can only
    display an HTML page 100% correctly if it knows the HTML type and version
    used.
