What is HTML and What does HTML stand for
HTML, short for Hyper-Text Markup Language, is a language that allows you to write content while describing the nature of that content, for purpose of either layout or functionality.
HTML is the standard for all web pages. Even dynamic web pages (with extensions like ".php" or ".aspx") eventually produce HTML for you to view.
The "Markup" component of HTML is done by enclosing certain text with tags that contain some information about it. For example, by enclosing a title between <H2> and </H2> tags (H2 stands for headline level 2), it will be displayed in a more prominent way than regular text:
<h2>This is an h2 title.</h2>
HTML tags allow you to create hyperlinks, insert images, create tables, create forms and control their action, split your document into different regions, and much more.
HTML can also dictate exactly how your content is displayed on the screen, but in recent years it's become best practice to separate the two. HTML is now left mostly for writing your content; formatting it is done through an accompanying <CSS> file.
Basic HTML is very simple. Even so, there are many site-building programs that allow you to create your site without ever writing an HTML tag. Another solution to bypass HTML is using a Content Management System (CMS). A CMS is a site with two faces: one for displaying the site's content, and one for modifying the site's content, where even this modification is done through Internet pages. In other words, a site-builder or a CMS provide you with a visual interface, while creating HTML (or dynamic code and later HTML) for you behind the scenes.
