Overview of the Web: What is HTML, CSS, and JavaScript?
When we browse the internet and interact with websites, we’re seeing the result of three core technologies that work together to create the modern web. These three technologies are HTML, CSS, and JavaScript. Let’s break down each one and understand their role in web development.
1. HTML (Hypertext Markup Language)
What is HTML? HTML is the backbone of every web page. It’s a markup language used to structure content on the web. Think of HTML as the skeleton of a website, organizing and structuring all the content that users will see in the browser.
HTML is made up of tags and elements. These tags describe different parts of the page, like headings, paragraphs, links, images, forms, and more. These elements tell the browser how to display and structure the page content.
What HTML does:
- Defines the structure of a web page (e.g., headings, paragraphs, and lists).
- Displays content like text, images, and videos.
- Creates links to other pages or resources on the web.
- Supports forms for gathering user input, such as contact forms or login pages.
Example of HTML:
<!DOCTYPE html>
<html>
<head>
<title>My Web Page</title>
</head>
<body>
<h1>Welcome to My Web Page</h1>
<p>This is a simple web page.</p>
<a href=”https://example.com”>Visit Example</a>
</body>
</html>
