What is HTML and how does it work?
HTML (Hyper Text Markup Language) is a markup language for specifying/describing the different elements of a web page. HTML makes use of tags, attributes, and properties to describe these elements (headings, paragraphs, images, tables etc.) so that they can be interpreted and displayed correctly by a web browser. Most HTML tags have 2 parts to them: an opening tag and a closing tag. For example, the HTML tag for a paragraph <p> would be used as follows to display the words 'Hello World!': <p>Hello World!</p>
What is CSS and what is the difference between CSS and HTML?
CSS stands for Cascading Style Sheets. Whereas HTML is concerned with specifying the content or structure of a web page, CSS is concerned with the appearance (or style) of this content i.e. how it will be displayed.
Basic structure of a web page
<!DOCTYPE html>
<html>
<head>
</head>
<body>
All content that you want the viewer to see should be inserted here (i.e. between the 'body' tags).
</body>
</html>
A very simple web page
The following web page displays 'Hello World!' on the screen.
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p>Hello World!</p>
</body>
</html>
How to create a web page
In order to create a web page you will first need to learn a little about HTML and how it works. You will then need to use a text editor such as Notepad++, Textedit, Atom or Visual Studio Code to create your HTML code (i.e. your web page). Save your completed page with a .htm/.html file extension and make it available online so that it can be viewed by anyone with a web browser.
