What is HTML? One awesome text in 2021

Firstly, what is HTML is short for “HyperText Markup Language”. That may sound scary, but it simply means it is a language for describing web-pages using ordinary text. HTML is not a complex programming language.

HTML Files (What is HTML)

Every web page is actually a HTML file. Each HTML file is just a plain-text file, but with a .html file extension instead of .txt, and is made up of many HTML tags as well as the content for a web page.

A web site will often contain many html files that link to each other. You can edit HTML files with your favourite editor.

HTML Tags (What is HTML)

HTML tags are the hidden keywords within a web page that define how your web browser must format and display the content.

Most tags must have two parts, an opening and a closing part. For example, <html> is the opening tag and </html> is the closing tag. Note that the closing tag has the same text as the opening tag, but has an additional forward-slash ( / ) character. I tend to interperet this as the “end” or “close” character.

There are some tags that are an exception to this rule, and where a closing tag is not required. The <img> tag for showing images is one example of this.

Each HTML file must have the essential tags for it to be valid, so that web browsers can understand it and display it correctly.

The rest of the HTML file can contain as little or as many tags as you want to display your content.

Tag Attributes (What is HTML)

Attributes allow you to customise a tag, and are defined within the opening tag, for example:
<img src="image1.jpg"> or <p align="center"> ... </p>

Attributes are often assigned a value using the equals sign, such as border="0" or width="50%", but there are some that only need to be declared in the tag like this: <hr noshade>.

Most attributes are optional for most tags, and are only used when you want to change something about the default way a tag is displayed by the browser. However, some tags such as the <img> tag has required attributes such as src and alt which are needed in order for the browser to display the web page properly.

Example:

Below is a basic html document, containing all the essential tags. You can copy the code below, paste it into your editor, and save as mypage.html to start your own web page.

<html>
 <head>
  <title>My Page Title</title>
 </head>
 <body>

  This is where all my web page content goes!

 </body>
</html>

What is HTML

What is HTML (HyperText Markup Language) is the most basic building block of the Web. It defines the meaning and structure of web content. Other technologies besides HTML are generally used to describe a web page’s appearance/presentation (CSS) or functionality/behavior (JavaScript).

“Hypertext” refers to links that connect web pages to one another, either within a single website or between websites. Links are a fundamental aspect of the Web. By uploading content to the Internet and linking it to pages created by other people, you become an active participant in the World Wide Web. What is HTML?

HTML uses “markup” to annotate text, images, and other content for display in a Web browser. HTML markup includes special “elements” such as <head><title><body><header><footer><article><section><p><div><span><img><aside><audio><canvas><datalist><details><embed><nav><output><progress><video><ul><ol><li> and many others.

An HTML element is set off from other text in a document by “tags”, which consist of the element name surrounded by “<” and “>“.  The name of an element inside a tag is case insensitive. That is, it can be written in uppercase, lowercase, or a mixture. For example, the <title> tag can be written as <Title><TITLE>, or in any other way.
