10 major learning points on HTML


  1.  Backbone behind the website.
  • HTML or HyperText Markup Language is the standard markup language used to create web pages.
    2.   HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>). HTML tags most commonly come in pairs like <h1> and </h1>, although some tags represent empty elements and so are unpaired, for example <img>. The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening tags and closing tags).

    3.   The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page.
    
    4.    HTML describes the structure of a website semantically along with cues for presentation, making it a markup language rather than a programming language.

    5.    HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts written in languages such as JavaScript which affect the behavior of HTML web pages.

    6.    HyperText Markup Language is a markup language that web browsers use to interpret and compose text, images and other material into visual or audible web pages. Default characteristics for every item of HTML markup are defined in the browser, and these characteristics can be altered or enhanced by the web page designer's additional use of CSS.
     
    7.    "HTML tags" and "HTML elements" are often used to describe the same thing.

      8.

  • HTML elements can have attributes
  • Attributes provide additional information about an element
  • Attributes are always specified in the start tag
  • Attributes come in name/value pairs like: name="value"
     9.   Most websites have put their content in multiple columns (formatted like a magazine or newspaper).
Multiple columns are created by using <div> or <table> elements. CSS are used to position elements, or to create backgrounds or colorful look for the pages.

    10.  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 determine how the content of the HTML page is to be presented/displayed to the user:
