HTML + Javascript

By using HTML and CSS we can develop only static and responsive web pages only. But for more attractive, dynamic and interactive web pages we must use javascipt.
Javascript is the most popular scripting language used for websites.JavaScript makes HTML pages more dynamic and interactive.

JavaScript is used with HTML and CSS because it provides dynamic functionality to a website. HTML is used to structure the content of a website, while CSS is used to style and layout the website’s elements. However, these two languages alone cannot provide interactivity to a website. That’s where JavaScript comes in.

JavaScript is a scripting language that allows developers to add interactive elements to a website, such as animations, pop-up messages, and interactive forms. It can also be used to modify HTML and CSS on the fly, allowing for even more dynamic content.

In addition to providing interactive functionality, JavaScript is also widely supported by all modern web browsers, making it a popular choice for web development. By using JavaScript with HTML and CSS, developers can create rich, interactive websites that provide a great user experience.

Here are some more points to explain why we use JavaScript with HTML and CSS:

  • Client-side scripting: JavaScript is a client-side scripting language, meaning that it runs on the user’s browser rather than the server. This makes it ideal for creating dynamic and interactive user experiences that are responsive to user actions.
  • Event-driven programming: JavaScript is event-driven, meaning that it can respond to user actions such as clicking a button, scrolling a page, or typing in a form. This makes it ideal for creating interactive interfaces and user experiences.
  • AJAX: JavaScript can be used to make asynchronous requests to a server without reloading the entire page. This technique is known as AJAX (Asynchronous JavaScript and XML), and it allows for faster, more responsive websites that provide a seamless user experience.
  • Compatibility: JavaScript is supported by all major web browsers, making it a reliable and widely-used language for web development.
  • Libraries and frameworks: There are many JavaScript libraries and frameworks available that make it easier to develop complex web applications. Examples include React, Angular, and Vue.js.
  • Server-side programming: JavaScript can also be used for server-side programming using platforms like Node.js. This allows developers to write both client-side and server-side code in the same language, which can simplify the development process and improve code maintainability.

Example: HTML + JavaScript

<!DOCTYPE html>
<html>

<body>
    <h1>JavaScript First Example</h1>
    <button type="button" onclick="document.getElementById('demo').innerHTML = Date()">
        Current Date and Time.</button>
    <p id="demo"></p>
</body>

</html>
