Web development has become a major part in every sector’s website creation. The three foundation technologies that help power almost every website are HTML5, CSS, and JavaScript. When used together, they work as the backbone of modern website design, providing a development area to create functionalyl, visually appealing, and equally interactive websites.
Here is a brief description of each of them with examples.
1. HTML5
HTML short for hypertext markup language, is a standard markup language that is a structural language for any website development. HTML5 is the latest version of HTML, adding new features like semantic elements, video support and improved accessibility. These features of HTML5 help developers provide better structure by uniquely using each of them. Semantic elements have tags like <headers>, < footers>, and <articles> that provide structure to a web page helping developers organize their web page content easily, multimedia features allow developers to use tags like, <audios> and <videos> for their web page directly in bed videos and audios to the web pages without the need of external login like flash. Canvas and SVG graphics are other cool features that help designers draw graphics without any plugins making HTML5 more accessible and developer-friendly.
Example
<!DOCTYPE html>
<html lang=”en”>
<head>
<title>HTML5 Example</title>
</head>
<body>
<header>
<h1>Welcome to HTML5</h1>
</header>
<section>
<p>HTML5 makes structuring web pages easier and more efficient!</p>
<video controls>
<source src=”example.mp4″ type=”video/mp4″>
Your browser does not support the video tag.
</video>
</section>
</body>
</html>
2.CSS
CSS stands for cascade style sheet. It is responsible for the visual aspects of a website’s use and design. It is the style master of website design. CSS is used to define how HTML elements, such as layout, colors, fonts, and responsiveness, should look on a web page. There are many features in CSS that provide developers with flexibility with the visuals of the website.
Selectors and properties allow developers to target specific elements in HTML and apply different styles like colors, borders, and margins. Text box and grid layout allows the creation of flexible and responsive designs for each web page. CSS also has animation and transition elements that help to bring life to the elements with smooth effects. Also, the media queries enable designers to adapt to various screen sizes when comes to the responsiveness of a design.
Example
body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
color: #333;
}
header {
background: #4CAF50;
color: white;
padding: 10px 0;
text-align: center;
}
section p {
font-size: 18px;
line-height: 1.6;
}
3. JavaScript
JavaScript is an interesting programming language that adds creativity and dynamic behavior to a website during the programming period. It has multiple features that help developers do simple tasks like validating form input to complex tasks like single-page applications. JavaScript has multiple features that play a major role in the process of website development. DOM manipulation in JavaScript can dynamically change HTML content and style without refreshing the page making the developer’s work easier. Other features like an event handle can react to user actions such as clicks or keyboard inputs, API integration enables facing data from external API and displays them dynamically and cross-browser compatibility lets developers work with various frameworks and libraries across various browsers.
Examples
document.addEventListener(“DOMContentLoaded”, function () {
const button = document.createElement(‘button’);
button.textContent = “Click Me!”;
document. body.appendChild(button);
button.addEventListener(‘click’, function () {
alert(“You clicked the button!”);
});
});
To create a functionally and visually appealing website developers use all these programming languages in combination. HTML defines the structure and content, CSS adds visual flairs and styling, and JavaScript brings interactivity making a website dynamically engaging.
