🙋 Introduction

The border property in CSS is a shorthand property used to set the border around an element. This property allows you to define the width, style, and color of the border in a single declaration.

Borders are an essential aspect of web design, as they help define the boundaries of elements and enhance the overall visual structure of a webpage.

💡 Syntax

The border property can be used in various ways, allowing you to specify one, two, or all three border attributes (width, style, color).

Syntax

Copied

element {
  border: width style color;
}

🎛️ Default Value

If the border property is used without specifying any values, the default value is medium none color. This means the border will not be visible as its style is set to none.

🏠 Property Values

width: Defines the thickness of the border. It can be specified in pixels (px), ems (em), or keywords like thin, medium, thick.
style: Determines the appearance of the border. Common values include:
- none: No border (default).
- solid: A solid line.
- dotted: A series of dots.
- dashed: A series of dashes.
- double: Two solid lines.
- groove: A 3D grooved border that appears as though it is carved into the page.
- ridge: A 3D ridged border that appears as though it is coming out of the page.
- inset: A 3D inset border that makes the element appear embedded.
- outset: A 3D outset border that makes the element appear raised.
color: Defines the color of the border. It can be specified using color names (e.g., red), hexadecimal values (e.g., #ff0000), RGB values (e.g., rgb(255, 0, 0)), or HSL values (e.g., hsl(0, 100%, 50%)).

📄 Example

In this example, we'll create a solid black border around a div element with a width of 2 pixels.

  </style>
</head>
<body>
  <h1>Div with Custom Border</h1>
  <div>
    This div element has a 2px solid black border.
  </div>
</body>
</html>

🖥️ Browser Compatibility

The border property is widely supported in all modern browsers, including Chrome, Firefox, Safari, Edge, and Opera. This property has been a part of the CSS specification since the early versions, so it works consistently across different platforms and devices.
