HTML: A fun programming language

                What HTML stands for is hypertext markup language.  The definition of HTML is a set of tags and rules for using them in hypertext documents.   HTML is a very fascinating it can do many things.  HTML is a text and image formatting language used by web browsers to dynamically format web pages.  You can create your very own web page with HTML.  Web Pages must be written with HTML.  HTML is not a programming language it’s a markup language.  Markup language is a set of words and symbols for describing the identity of pieces of a document.  And a markup language is a set of markup tags.  Markup tags are used to describe WebPages.  Sometimes the HTML markup tags are called HTML tags.  HTML tags are keywords in angle brackets. 
For example it would look like <html>.  An HTML document is a webpage.  The inventor of HTML was Tim Berners Lee in the year 1991.  He was assisted by his colleagues in the scientific business in Switzerland.  HTML allows images and objects to be embedded and can be used to create interactive forms.  HTML can also be used to include Cascading Style Sheets  to define the appearance and layout of text and other material.  Cascading Style Sheets is a style sheet language used to describe the presentation semantics of a document written in a markup language.  Html style attribute is to provide a common way to style all html elements.  Styles was introduced with HTML 4, as the new and preferred way to style HTML elements. With HTML styles, styles can be added to HTML elements directly by using the style attribute, or indirectly in separate style sheets. The abbreviation of cascading style sheets is CSS.  Html has gone through many different versions.  In 1995 HTML 2.0 was created.  Over the years until 2001 they upgraded html 3 times.  They just kept adding new features and making it better.  An HTML element is everything from the start tag to the end tag.  The element content is everything between the start and the end tag.  Headings are defined with the <h1> to <h6> tags.  <h1> defines the largest heading. <h6> defines the smallest heading.  HTML comments can be inserted into the HTML code to make it more readable and understandable.
Comments are ignored by the browser and are not displayed.  To find html codes for a web page you are viewing, you right click on the page then you go to view source.  Then a page will come up with all the html codes on it.  Html tags are defined with <p>.  HTML attributes are defined as <a>.  HTML uses tags like <b> and <i> for formatting output, like bold or italic text.  These HTML tags are called formatting tags.  Here are some more examples of formatting tags.  <big> defines big text, <em> defines emphasized text, <small> defines small text, <strong> defines strong text, <del> defines deleted text, <ins> defines inserted text.  There are many other tags but these where just some simple examples that I found.  Html style attribute is to provide a common way to style all html elements.  A hyperlink is a word, group of words, or image that you can click on to jump to a new document or a new section within the current document.  The HTML code for a link is simple.  It looks like this <a href="url">Link text</a>.  Html tables are divided into rows and each row is divided into data cells.  <td> stands for table data and holds contents of a data cell. A <td> tag can contain links, texts, images, lists, forms, other tables, etc.  With html frames, you can display more than one HTML document in the same browser window. Each HTML document is called a frame. The disadvantages of using frames are 1. The web developer must keep track of more HTML documents and 2. It is difficult to print the entire page.  HTML colors are defined using a hexadecimal notation for the combination of Red, Green, and Blue color values. The colors red, green and blue can give you 16 million different color choices.  Html is a lot of work.  You have to learn a lot.  But when you learn all the neat tricks to html you will benefit in making your own webpage. You can be known for making one of the best web pages.  What I found fascinating is that you can view the html codes by right clicking on the page.
