Two of the major innovations of the World Wide Web were:
1. Web pages could be requested from a web server anywhere in the world and displayed with “easy to use” software call a browser
2. These web pages usually contain hyperlinks which, when clicked, retrieve another web page from the same or a different web server
Web pages are coded using HTML, which stands for Hypertext Markup Language, the language used to markup plain text in order to control its look and behaviour when displayed in a browser. There are different versions of HTML, and our examples will use HTML 5.0 (the most current version as of May, 2014).
Hypertext is text that can be displayed by a web browser. Hypertext usually contains hyperlinks which, as explained above, are clickable links to other web pages.
Markup is the process of taking plain text and adding HTML elements to it through the use of tags so that it can be processed and displayed by a browser. Tags are usually enclosed in angle brackets <> and often contain a beginning tag and an end tag.
For example to display this sentence: Sometimes we want certain words to appear as bold.
we would code it as: Sometimes we want <strong>certain words</strong> to appear as bold.
Our purpose here is to give you a quick explanation of HTML for non-coders. If you want a great tutorial on HTML,

To code the preceding line the following HTML was used:

In the next installment, we will take a look as CSS, another language, which gives us more control of how web pages are displayed in the browser.
