🎯 Examples

1. Solid top border style

header {
  border-top-style: solid;
  border-top-width: 3px;
  border-top-color: black;
}

Creates a solid black line at the top of the header.

2. Dashed top border style

section {
  border-top-style: dashed;
  border-top-width: 2px;
  border-top-color: #007BFF;
}

Adds a blue dashed line on top of the section.

3. No top border

footer {
  border-top-style: none;
}

Removes the top border completely.

🔍 How It Works

• The style must be set to anything other than none for the border to be visible.
• Usually combined with border-top-width and border-top-color for complete control.
• Can be overridden by shorthand border-top or the universal border property.

🛠️ Best Practices

• Use solid, dashed, or dotted for clean and modern borders.
• Use none to hide the top border while keeping other borders intact.
• Use 3D styles like groove or ridge sparingly for decorative or retro designs.
• Combine with transitions for animated border effects on hover or focus.
