 To create a chessboard using HTML, CSS, and JavaScript, you can follow these steps:

1. **Set up your HTML**: Create a basic HTML file with a `div` element to hold the chessboard.

2. **Style your chessboard with CSS**: Add CSS styles for the chessboard container and each square (dark and light colors).

3. **Generate the chessboard with JavaScript**: Use JavaScript to dynamically create the squares for the chessboard.

Here's an example code that demonstrates how to create a chessboard:

```html
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Chess Board</title>
    <style>
        /* Chessboard container styles */
        #chessboard {
            width: 320px; /* Change this value to adjust size */
            height: 320px;
            display: grid;
            grid-template-columns: repeat(8, 1fr);
            grid-template-rows: repeat(8, 1fr);
        }

        /* Dark square styles */
        .dark {
            background-color: #769656; /* Dark green */
            width: 100%;
            height: 100%;
        }

        /* Light square styles */
        .light {
            background-color: #eeeed2; /* Light beige */
            width: 100%;
            height: 100%;
        }
    </style>
</head>

<body>
    <!-- Chessboard container -->
    <div id="chessboard"></div>

    <script>
        // Create chessboard
        function createChessboard() {
            const chessboard = document.getElementById('chessboard');

            // Create 64 squares (8x8)
            for (let row = 0; row < 8; row++) {
                for (let col = 0; col < 8; col++) {
                    // Determine if the square should be dark or light
                    const isDarkSquare = (row + col) % 2 === 0;

                    // Create a square div
                    const square = document.createElement('div');

                    // Assign dark or light class based on the position
                    square.className = isDarkSquare ? 'dark' : 'light';

                    // Append the square to the chessboard container
                    chessboard.appendChild(square);
                }
            }
        }

        // Call the function to create the chessboard when the page loads
        window.onload = createChessboard;
    </script>
</body>

</html>
```

Here's what the code does:

- The `#chessboard` div in the HTML is the container for the chessboard.
- The CSS styles define the size and appearance of the chessboard (`grid` layout) and the dark and light squares.
- The JavaScript function `createChessboard` dynamically creates 64 squares (8 rows and 8 columns), alternating between dark and light classes based on their position (even or odd row and column indices).
- The JavaScript function is called when the window loads to create the chessboard.

You can adjust the width and height of the chessboard in the CSS as desired to change its size.

About HTML

HTML(Hyper Text Markup language) is the standard markup language for Web pages, was created by Berners-Lee in the year 1991. Almost every web page over internet might be using HTML.

Syntax help

Fundamentals

Any HTML document must start with document declaration <!DOCTYPE html>
HTML documents begin with <html> and ends with </html>
Headings are defined with <h1> to <h6> where <h1> is the highest important heading and <h6> is the least important sub-heading.
Paragraphs are defined in <p>..</p> tag.

Links are defined in <a> tag.

Example:

<a href="https://onecompiler.com/html">HTML online compiler</a>

Images are defined in <img> tag, where src attribute consists of image name.
Buttons are defined in <button>..</button> tag
Lists are defined in <ul> for unordered/bullet list and <ol> for ordered/number list, and the list items are defined in <li>.

HTML Elements and Attributes

HTML element is everything present from start tag to end tag.
The text present between start and end tag is called HTML element content.
Anything can be a tagname but it's preferred to put the meaningful title to the content present as tag name.
Do not forget the end tag.
Elements with no content are called empty elements.
Elements can have attributes which provides additional information about the element.
In the below example, href is an attribute and a is the tag name.
Example:
```
<a href="https://onecompiler.com/html">HTML online compiler</a>
```

CSS

CSS(cascading style sheets) describes how HTML elements will look on the web page like color, font-style, font-size, background color etc.

Example:

Below is a sample style sheet which displays heading in green and in Candara font with padding space of 25px.

body{
  padding: 25px;
}
.title {
	color: #228B22;
	font-family: Candara;
}

HTML Tables

Table row should be defined in <tr> tag
Table header should be defined in <th> tag
Table data should be defined in <td> tag
Table caption should be defined in <caption> tag

HTML-Javascript

Javascript is used in HTML pages to make them more interactive.
<script> is the tag used to write scripts in HTML
You can either reference a external script or write script code in this tag.

Example

<script src="script.js"></script>
