Difference between CSS and JavaScript

Differences CSS Javascript

A website is developed using HTML. HTML provides the backbone and structure for the website. However, using HTML alone, we can't create our desired website. Cascading Style Sheets (CSS) adds a styling layer to the website, applying formatting, changing layouts, and making the website visually appealing. JavaScript is a programming language that makes websites functional and interactive, adding animations, pop-up screens, and user interaction features.

What is CSS?

CSS stands for Cascading Style Sheets. CSS is a language used to style HTML documents. Using CSS, we can change document styles such as page layout, colors, font styles, and much more.

HTML creates the basic structure of a website, but it doesn't look attractive on its own. Although HTML has some styling attributes, they are not sufficient for creating beautiful websites. CSS transforms the appearance of websites and provides an attractive user interface.

CSS Syntax

The syntax of CSS consists mainly of two parts selector and declaration. Consider the following example ?

selector {
    property: value;
}

Here's a practical example ?

<!DOCTYPE html>
<html>
<head>
<style>
    p {
        background-color: blue;
        color: white;
        padding: 10px;
    }
</style>
</head>
<body>
    <p>This is a styled paragraph.</p>
</body>
</html>

A paragraph with blue background, white text, and 10px padding appears on the page.

In this example, "p" is the selector (targeting paragraph elements), and everything within the curly braces is the declaration (the styling rules applied).

Types of CSS

CSS can be declared in three ways ?

External CSS ? CSS is written in a separate file with a .css extension and linked to the HTML file.
Internal CSS ? CSS is written within the HTML document in the <head> section using <style> tags.
Inline CSS ? CSS properties are mentioned directly inside the HTML tag using the style attribute.

Advantages of CSS

Makes pages more attractive than plain HTML
Code reusability across multiple pages saves time
Faster loading due to reduced code redundancy
Easy maintenance by changing styles in one place

What is JavaScript?

JavaScript is a programming language used in web development to make web pages dynamic and interactive. While HTML creates the structure and CSS handles the presentation, JavaScript adds the behavior layer. It enables features like pop-up screens, live updates, form validation, and user interactions.

JavaScript has evolved beyond web development and can now be used to create mobile applications, desktop applications, and even games. Its versatility makes it one of the most popular programming languages.

To simplify development, various JavaScript frameworks have been created, such as React, Angular, and Vue for front-end development, and Node.js for back-end development.

Advantages of JavaScript

Fast execution as it's an interpreted language
Can be used for both front-end and back-end development
Compatible with other programming languages
Creates interactive and dynamic user interfaces
Enables full-stack application development
