Set Inset border with CSS

Javascript Web Development Front End Scripts

To set inset border with CSS, use the border-style property with value inset. The inset border style creates a 3D effect that makes the element appear pressed into the page.

Syntax

border-style: inset;
/* or for specific sides */
border-top-style: inset;
border-right-style: inset;
border-bottom-style: inset;
border-left-style: inset;

Example

<!DOCTYPE html>
<html>
<head>
    <style>
        .no-border {
            border-width: 4px;
            border-style: none;
            padding: 10px;
            margin: 10px 0;
        }
        
        .inset-border {
            border-width: 4px;
            border-style: inset;
            padding: 10px;
            margin: 10px 0;
            border-color: #888;
        }
        
        .inset-thick {
            border-width: 8px;
            border-style: inset;
            border-color: #666;
            padding: 15px;
            margin: 10px 0;
            background-color: #f0f0f0;
        }
    </style>
</head>
<body>
    <p class="no-border">
        This paragraph has no border (border-style: none).
    </p>
    
    <p class="inset-border">
        This paragraph has an inset border - notice the 3D pressed-in effect.
    </p>
    
    <p class="inset-thick">
        This paragraph has a thicker inset border with background color.
    </p>
</body>
</html>

Key Points

  • The inset border style creates a 3D sunken appearance
  • It works best with a border width of at least 2-3 pixels to show the effect clearly
  • The effect is opposite to outset border style
  • Border color affects how pronounced the 3D effect appears

Browser Compatibility

The inset border style is supported in all modern browsers including Chrome, Firefox, Safari, and Edge.

Conclusion

Use border-style: inset to create a pressed-in 3D effect. Combine with adequate border width and appropriate colors for the best visual result.
