Elements of HTML
HTML elements are called with a general notation “TAGS” used to markup the content of a document for a web browser. HTML tags contain a left angle bracket (<), a tag name, and a right angle bracket (>). There are two kind of HTML tags:
- Paired Tags – Paired tags should always consist of a starting and a closing tag. Most of the HTML tags are paired tags like <H1> and </H1> where H indicates the heading.
- Single Tag – These tags are not necessarily to have a closing tag. Example of a single tag includes a line break <BR>.
HTML elements can be a heading, a table or a list and contains text, image or media content. Some tags may include an attribute to provide more information that is included inside the start tag. For example, you can align your heading left or right by including the alignment attribute to the heading tag as:
<H1 ALIGN="left">This is an example heading</H1>
How Does HTML Work?
HTML is used to create platform independent hypertext documents which are stored on a web server. In order to view these documents stored on a web server we need to have the followings:
- A personal computer called as client.
- A web browser running on a personal computer. Example browsers include Chrome, Safari, Firefox and Internet Explorer.
When a user enters a URL in a browser running on a personal computer, it sends a request to a web server through HTTP (HyperText Transfer Protocol). The server sends an HTML document as a response to the client request. The entire process of web communication is shown in the below picture.
Since the HTML document is a marked up content, web browser starts interpreting the content and displays it as a beautiful webpage on the window. Though HTML is a standard language each browsers follow their own way of interpreting the HTML tags and hence the display of HTML document is completely depends on the browser.
Note: Open any website in a browser like Google Chrome, Mozilla Firefox, Safari and Internet Explorer to see the difference in content display. All HTML tags are not supported by all web browsers. Browser will ignore a tag when it is not supported.
