CSS Dropdown

CSS Dropdown menus are used to create a list of links that appear when you hover over or click on an element. It’s a neat way to save space and organize navigation menus in a user-friendly way.

📐 Syntax:

/* Dropdown Container */
.dropdown {
  position: relative;
  display: inline-block;
}

/* Dropdown Menu */
.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f1f1f1;
  min-width: 160px;
  box-shadow: 0px 8px 16px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

/* Display dropdown on hover */
.dropdown:hover .dropdown-content {
  display: block;
}

/* Links inside the dropdown */
.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

/* Change color of links on hover */
.dropdown-content a:hover {
  background-color: #ddd;
}
  

🧪 Live Example:

🔧 Common Properties:

• position: relative; → The dropdown container is positioned relative to its normal position, allowing the menu to be positioned absolutely within it.
• display: none; → Hides the dropdown menu by default.
• display: block; → Makes the dropdown menu visible when hovering over the parent element.
• z-index → Ensures that the dropdown appears on top of other elements when it's shown.
• position: absolute; → Positions the dropdown menu relative to its container.

📱 Responsive Layout Tip:

Dropdown menus can be tricky to navigate on mobile devices. Consider adding a "click-to-open" feature for smaller screens and ensuring that the dropdown does not hide too quickly or appear outside of the viewport.
