CSS UI Components

CSS UI components like buttons, tooltips, navbars, and dropdowns make websites interactive, user-friendly, and responsive. These components improve usability, SEO (through better UX), and accessibility.

CSS Tooltips

Tooltips are small information boxes that appear when a user hovers, clicks, or focuses on an element. They provide extra context without cluttering the UI.

Types of Tooltips

Hover Tooltips – Show when the user hovers the mouse.
Click Tooltips – Appear only when the user clicks.
Custom Tooltips – Designed with advanced styles/animations.

Tooltip Example

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Tooltip Example</title>
<style>
.tooltip {
  position: relative;
  display: inline-block;
  cursor: pointer;
}

.tooltip .tooltip-text {
  visibility: hidden;
  width: 140px;
  background: #333;
  color: #fff;
  text-align: center;
  padding: 6px;
  border-radius: 5px;
  position: absolute;
  bottom: 125%;
  left: 50%;
  transform: translateX(-50%);
  opacity: 0;
  transition: opacity 0.3s;
}

.tooltip:hover .tooltip-text {
  visibility: visible;
  opacity: 1;
}
</style>
</head>
<body>
<div class="tooltip">Hover me
  <span class="tooltip-text">This is a tooltip!</span>
</div>
</body>
</html>

CSS Button

Buttons are the call-to-action (CTA) elements of a website. They guide users to sign up, purchase, or navigate.

<button class="button">Basic Button</button>

.button {
  background: #4CAF50;
  color: white;
  padding: 12px 24px;
  border: none;
  border-radius: 6px;
  font-size: 16px;
  cursor: pointer;
}

Hover & Active States

Adding hover/active states improves interactivity.

<button class="button-hover">Hover Me</button>

.button-hover {
  background: #008CBA;
  color: white;
  padding: 12px 24px;
  border: none;
  border-radius: 6px;
  cursor: pointer;
  transition: background 0.3s;
}

.button-hover:hover {
  background: #005f73;
}

Gradient & Animated Buttons

Gradient buttons stand out and increase click rates.

<button class="button-gradient">Gradient Button</button>

.button-gradient {
  background: linear-gradient(45deg, #ff7e5f, #feb47b);
  color: white;
  padding: 12px 24px;
  border: none;
  border-radius: 8px;
  cursor: pointer;
  font-size: 16px;
  transition: transform 0.3s;
}

.button-gradient:hover {
  transform: scale(1.05);
}

Icon Buttons Example

<button class="button-icon">🔍 Search</button>

.button-icon {
  background: #333;
  color: white;
  padding: 12px 20px;
  border: none;
  border-radius: 6px;
  cursor: pointer;
  display: flex;
  align-items: center;
  gap: 8px;
}

.button-icon:hover {
  background: #555;
}

CSS Pagination

Pagination divides content into multiple pages, improving navigation, readability, and SEO by preventing long scrolling pages.

Simple Pagination Example (HTML + CSS)

<ul class="pagination">
  <li><a href="#">«</a></li>
  <li><a href="#" class="active">1</a></li>
  <li><a href="#">2</a></li>
  <li><a href="#">3</a></li>
  <li><a href="#">»</a></li>
</ul>

.pagination {
  display: flex;
  list-style: none;
  justify-content: center;
  gap: 10px;
}

.pagination li {
  display: inline;
}

.pagination a {
  padding: 8px 14px;
  text-decoration: none;
  background: #f1f1f1;
  color: #333;
  border-radius: 5px;
  transition: background 0.3s;
}

.pagination a:hover,
.pagination a.active {
  background: #4CAF50;
  color: white;
}

Active/Disabled States

<a href="#" class="disabled">« Prev</a>

.disabled {
  color: #aaa;
  pointer-events: none;
  background: #eee;
}

CSS Navigation Bars (Navbars)

A navbar usually contains brand/logo, links, and dropdown menus.

  text-decoration: none;
  padding: 10px 20px;

  background: #333;
  display: flex;
  flex-direction: column;

CSS Dropdowns

Dropdowns allow users to expand hidden options, often used in forms and navigation menus.

Example

<div class="dropdown">
  <button>Menu</button>
  <div class="dropdown-content">
    <a href="#">Profile</a>
    <a href="#">Settings</a>
    <a href="#">Logout</a>
  </div>
</div>

.dropdown {
  position: relative;
  display: inline-block;
}

.dropdown button {
  background: #4CAF50;
  color: white;
  padding: 12px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
}

.dropdown-content {
  display: none;
  position: absolute;
  background: #f1f1f1;
  min-width: 160px;
  border-radius: 6px;
  box-shadow: 0 8px 12px rgba(0,0,0,0.2);
  z-index: 1;
}

.dropdown-content a {
  padding: 10px 16px;
  display: block;
  text-decoration: none;
  color: #333;
}

.dropdown-content a:hover {
  background: #ddd;
}
