πŸ““ HyperText Markup Lanuage (HTML)

If you have ever written a report or an article you probably were given some set of standards for how your words should be formatted. For example, you may have been instructed that the first line of paragraphs should be indented or vis vera instructed that all lines after the first should be indented. You likely were instructed on how you denote quotes, when to bold or italics text, and how to format the header, title, references, etc.

HyperText Markup Language (HTML) is a coding language that serves a similar purpose. It is used to standardize the structure and formatting of text documents intended to be displayed in a web browser. HTML is at the core of every webpage you see on the internet, regardless of the complexity of the website.

Introduction to HTML​

What does HyperText and Markup Language mean?

Hypertext (when not used in context with HTML, the β€œt” is lowercase) is text displayed on a computer that contains links to other text. Without getting too much into the subject, Hypertext is kinda just a β€œtechnical nerdy” way of saying β€œa link.” Most people just say β€œlink.” It may seem odd but learning exactly what is Hypertext is off topic and not important right now for learning about HTML. Just know that HT in HTML stands for HyperText.

A markup language is used to control the structure, formatting, and relationship between parts of a text document. To give an analogy, let's say you wrote a paper and then gave it to your English teacher for review. Your English teacher then used a blue pen to mark on your paper where there are formatting errors. Your English teacher then gives the paper back to you and expects you to correct all formatting errors. In this analogy, the English teacher is enforcing their markup language on your paper. They have formatting rules they expect you to follow.

This is what HyperText Markup Language (HTML) is doing for us too; enforcing structure and formatting standards for text intended to be displayed on the web. In fact, all formatted digital content relies on a markup language. HTML is by far the most standard meaning it is the most widely used and applicable to many professions; not just developers.

How HTML Works​

This will be a brief overview so you can get the general big picture of how HTML works. It's kinda a funny thing in code that you often don’t need to get into the details of a coding language or tool before you’re expected to start using it.

This is how HTML works:

HTML is written in a file, that file is rendered by the web browser and it is displayed according to the HTML syntax.

That's all we really need to know about HTML works for now. Using HTML is providing your web browser with instructions for how the text should be displayed.

Basic Structure of an HTML Document​

HTML documents have the file extension .html You can name HTML documents whatever you like. However, the homepage of a website (in other words, the first page a visitor to the website sees) is conventionally named index.html. We’ll be following this convention as well through the lessons on

This is the basic structure of an HTML document:

<!DOCTYPE html>
<html lang="en-US">

  • <!DOCTYPE html> is the Document Type Declaration. It tells the browser (such as Chrome) what kind of document this is so it can be rendered correctly.

  • <html lang="en-US"> … </html> encloses all content within the HTML document. Specifically the lang="en-US specifies that the language for this document is β€œenglish United States.” This is important information for screen readers so vision-impaired visitors to your website can still use it.

  • <body> </body> is where we will write our own HTML.
