HTML, CSS, and JavaScript are the three core technologies of front-end development. They are used to create the structure, style, and interactivity of web pages.
HTML (HyperText Markup Language) is the foundation of web pages. It is used to define the structure of a web page by defining the elements that make up the page, such as headers, paragraphs, images, and lists.
CSS (Cascading Style Sheets) is used to style web pages. It is used to define the look and feel of a web page, such as the colors, fonts, and layout.
JavaScript is a programming language that is used to add interactivity to web pages. It is used to create things like animations, forms, and games.
HTML, CSS, and JavaScript are essential skills for anyone who wants to work as a front-end developer. They are also valuable skills for anyone who wants to create their own web pages.
In this article, I will discuss the basics of HTML, CSS, and JavaScript. I will also provide some resources that you can use to learn more about these technologies.
HTML
HTML is a markup language that is used to define the structure of a web page. It is made up of elements, which are tags that are used to define the different parts of a web page. For example, the <h1> element is used to define a heading, and the <p> element is used to define a paragraph.
HTML elements can have attributes, which are additional pieces of information that can be used to customize the element. For example, the <h1> element can have an id attribute, which is used to uniquely identify the heading.
Here is an example of an HTML document:
HTML
<!DOCTYPE html>
<html>
<head>
<title>My First HTML Document</title>
</head>
<body>
<h1 id="my-heading">This is my first HTML document!</h1>
<p>This is a paragraph.</p>
</body>
</html>

This document defines a web page with a heading and a paragraph. The heading is styled with the id attribute, so it can be easily identified by other elements in the document.
CSS
CSS is a stylesheet language that is used to style web pages. It is used to define the colors, fonts, and layout of a web page.
CSS can be used to style both the HTML elements that make up a web page, and the images and other media that are embedded in the page.
CSS is a powerful tool that can be used to create highly customized web pages. It is also relatively easy to learn, so it is a great language for beginners to pick up.
Here is an example of a CSS stylesheet:

CSS
h1 {
color: red;
font-size: 24px;
}
p {
color: black;
font-size: 16px;
}
Use code with caution. Learn more
This stylesheet defines the styles for the h1 and p elements in the HTML document above. The h1 element is styled with red text and a font size of 24px. The p element is styled with black text and a font size of 16px.
JavaScript
JavaScript is a programming language that is used to add interactivity to web pages. It is used to create things like animations, forms, and games.
JavaScript can be used to interact with the user's browser, as well as with other web pages and APIs.
JavaScript is a powerful language that can be used to create a wide variety of interactive web pages. It is also relatively easy to learn, so it is a great language for beginners to pick up.
Here is an example of a JavaScript function:
JavaScript
function myFunction() {
alert("Hello, world!");
}
Use code with caution. Learn more
This function displays an alert box with the text "Hello, world!".
