The Basics of Coding: HTML, CSS, JavaScript
Coding has become an essential skill in today's digital world. Whether you are a student, a professional, or simply someone who wants to learn how to code HTML, CSS, and JavaScript are the building blocks of web development. In this article, we will explore the basics of coding using these three languages.
HTML (Hypertext Markup Language)
HTML is the foundation of web development. It is a markup language that is used to create the structure of web pages. HTML uses a series of tags to define the elements of a web page such as headings, paragraphs, images, and links.
To start using HTML, you need a text editor like Notepad or Sublime Text. You can create a new HTML document by opening a text editor and typing the following code:
HTML
<!DOCTYPE html>
<html>
<head>
<title>My Webpage</title>
</head>
<body>
<h1>Welcome to my webpage</h1>
<p>This is the first paragraph of my webpage.</p>
<img src="image.jpg" alt="My Image">
<a href="https://www.example.com">Click here to visit Example.com</a>
</body>
</html>
Let's break down this code. The <!DOCTYPE html> tag tells the browser that this is an HTML document. The <html> tag indicates the start of an HTML document, and the </html> tag indicates the end of the document. The <head> tag contains information about the document, such as the title, which is displayed in the browser's tab. The <body> tag contains the content of the webpage, such as headings, paragraphs, images, and links.
CSS (Cascading Style Sheets)
To use CSS, you need to create a separate CSS file with a .css extension. In the HTML document, you need to link to the CSS file using the <link> tag.
Here is an example of CSS code:
body {
background-color: #f2f2f2;
font-family: Arial, sans-serif;
}
h1 {
color: blue;
text-align: center;
}
p {
color: red;
font-size: 18px;
}
In this example, we have defined the style for the body, h1, and p elements. The background-colour property sets the background colour of the body element. The font-family property sets the font family for the body element. The colour property sets the colour of the text for the h1 and p elements. The text-align property sets the text alignment for the h1 element. The font-size property sets the font size for the p element.
JavaScript
To use JavaScript, you need to create a separate .js file and link to it using the <script> tag. Here is an example of JavaScript code:
function myFunction() { var x = document.getElementById("myText").value; document.getElementById("demo").innerHTML = x; }
In this example, we have created a function called myFunction(). This function gets the value of an input field with the ID myText and sets the value of a div element with the ID demo to the value of the input field. This function is triggered by a button click event.
