Before diving into this tutorial, make sure you have a basic understanding of HTML and CSS. You should also have a code editor installed on your computer.

Step 1: Understanding the border-width Property

The border-width property is used to set the width of an element’s border. It can take various values, including keywords like ‘thin,’ ‘medium,’ and ‘thick,’ or specific length values like pixels (px), em, rem, etc.

Let’s start with the basics. Create an HTML file with the following structure:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>CSS Border Width Tutorial</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="box"></div>
</body>
</html>

Now, create a CSS file (styles.css) and add the following code to set a border width:

/* styles.css */
.box {
    width: 200px;
    height: 200px;
    border: 5px solid black;
}

In this example, we’ve set the border width of the .box element to 5 pixels (5px solid black).

Step 2: Using Keywords for Border Width

CSS provides three keywords for border width: ‘thin,’ ‘medium,’ and ‘thick.’ These keywords represent predefined border widths.

Let’s update our CSS to use these keywords:

/* styles.css */
.box {
    width: 200px;
    height: 200px;
    border: thin solid black;
}

In this example, we’ve set the border width of the .box element to ‘thin.’ Save your files and observe the difference in border width compared to the previous step.

Step 3: Using Length Values for Border Width

You can also set a specific length for the border width. Length values can be in pixels, em, rem, etc. For example:

/* styles.css */
.box {
    width: 200px;
    height: 200px;
    border: 10px solid black;
}

Here, we’ve set the border width of the .box element to 10 pixels. Experiment with different length values to see how they affect the border width.

Step 4: Applying Border Width to Individual Sides

So far, we’ve applied the same border width to all sides of the element. However, you can set different border widths for each side (top, right, bottom, left) separately.

/* styles.css */
.box {
    width: 200px;
    height: 200px;
    border-width: 2px 5px 10px 20px;
    border-style: solid;
    border-color: red green blue yellow;
}

In this example, we’ve set different border widths for each side in a clockwise order (top, right, bottom, left).
