What is the difference between HTML, CSS and JavaScript?
In web design, coding is used to create functional and user-friendly websites, where web designers use coding languages such as HTML, CSS , and JavaScript in the development process.
It can be compared a bit to building a house:
- HTML (the foundation)
HTML defines the content of the website, and acts as the very foundation of the house. It defines the structure and determines where the walls, doors, and windows should be. Related to a website, it defines the content of the website. - CSS (interior)
CSS is used to give the website style, shape and color. In other words, CSS can be compared to the interior of a house. Where you decide how the house looks, the color of the walls, the type of floor and what the furniture should be like. - JavaScript (functions)
JavaScript, also known as js, makes a website interactive and dynamic. It controls interactive functions such as turning on lights automatically, opening the garage door with the remote control, or adjusting the temperature in the room based on the weather.
HTML, CSS, and JavaScript create a seamless and great user experience . Just like a house is designed to be appealing.
Have you considered updating your company's website? Here are 10 important points to consider before you start the process.
What is HTML?
HTML stands for “HyperText Markup Language” and is a markup language used to develop and structure the content on a website. In short, the HTML code tells us what should be on the website itself. Examples of this are headings, paragraphs and images.
Example of a simple HTML code
<!DOCTYPE html>
<html>
<head>
<title>Eksempelside</title>
</head>
<body>
<h1>Dette er en overskrift</h1>
<p>Dette er et avsnitt.</p>
</body>
</html>

What is CSS?
CSS stands for “Cascading Styles Sheets” and is used to describe the appearance and formatting of an HTML document. The CSS coding language often uses simple and logical terms. An example of this is “background-color: white;”. This code says that the background color of an element should be white.
What is JavaScript?
JavaScript is one of many programming languages used on websites to make them interactive and to give the website dynamic functionality. For example, by allowing you to click around, add text, or scroll up and down the website. This allows websites to offer you a more engaging and responsive experience.
