25+ Best CSS Snippets & Code Examples for Stunning Web Design

CSS (Cascading Style Sheets) is the backbone of modern web design. With a few lines of CSS, you can enhance the user experience, improve site speed, and create visually stunning layouts. In this guide, we will explore some of the best CSS snippets and tricks to boost your web development skills.

1. Responsive Navigation Menu

A well-designed navigation menu improves user experience. Here’s a simple responsive navigation bar:

  display: flex;
  justify-content: space-between;
  align-items: center;
  background: #333;
  padding: 15px;
}
.navbar a {
  color: white;
  text-decoration: none;
  padding: 10px 15px;
}
@media (max-width: 768px) {
  .navbar {
    flex-direction: column;
  }
}

2. Gradient Background Animation

A gradient background with a smooth transition effect can make your website stand out:

@keyframes gradientBG {
  0% {background-position: 0% 50%;}
  50% {background-position: 100% 50%;}
  100% {background-position: 0% 50%;}
}
body {
  background: linear-gradient(-45deg, #ff9a9e, #fad0c4, #fad0c4, #ffdde1);
  background-size: 400% 400%;
  animation: gradientBG 10s ease infinite;
}

3. Hover Effects for Buttons

Adding hover effects makes your buttons interactive and engaging:

button {
  background-color: #008CBA;
  border: none;
  color: white;
  padding: 10px 20px;
  text-align: center;
  transition: 0.3s;
}
button:hover {
  background-color: #005f73;
  transform: scale(1.1);
}

4. Sticky Header

Make your website header stick to the top when scrolling:

.header {
  position: sticky;
  top: 0;
  background: white;
  padding: 10px;
  box-shadow: 0px 4px 10px rgba(0, 0, 0, 0.1);
}

5. Animated Text Typing Effect

An animated typing effect makes headings look more dynamic:

.typing-effect::after {
  content: '|';
  animation: blink 0.8s infinite;
}
@keyframes blink {
  50% { opacity: 0; }
}

6. Glassmorphism Card Design

Glassmorphism is a modern UI trend that adds a blurred, transparent effect:

.card {
  background: rgba(255, 255, 255, 0.2);
  backdrop-filter: blur(10px);
  border-radius: 15px;
  padding: 20px;
}

7. Dark Mode Toggle

Easily switch between light and dark modes:

body.dark-mode {
  background: #121212;
  color: white;
}

To implement, use JavaScript:

document.querySelector('.toggle').addEventListener('click', () => {
  document.body.classList.toggle('dark-mode');
});

8. Scroll Progress Bar

Show a progress bar that indicates how far the user has scrolled:

#progress-bar {
  position: fixed;
  top: 0;
  left: 0;
  height: 5px;
  background: #ff5733;
  width: 0%;
}

JavaScript:

window.onscroll = function() {
  let scroll = document.documentElement.scrollTop;
  let height = document.documentElement.scrollHeight - document.documentElement.clientHeight;
  let scrolled = (scroll / height) * 100;
  document.getElementById("progress-bar").style.width = scrolled + "%";
};
