CSS Transitions — Add Smooth Animations

by

Want to make your website feel more modern and engaging? CSS Transitions are the easiest way to add smooth animations to your pages without using JavaScript. With just a few lines of code, you can animate color changes, size, position, or even opacity when a user interacts with elements like buttons, links, or images. In this MiniCoursey quick guide, you’ll learn how CSS Transitions work and how to apply them step by step to create a more dynamic, polished user experience.

What are CSS Transitions?

CSS Transitions allow property changes in CSS values to occur smoothly over a specified duration, rather than instantly. For example, instead of a button background snapping from blue to green when you hover, it fades smoothly between the colors, making the interaction feel more natural and user-friendly.

Basic Transition Syntax

To create a transition, you define which properties to animate and how long the transition should take. You can also adjust the timing function and delay if needed.


button {
  background: #007acc;
  color: #fff;
  padding: 12px 24px;
  border: none;
  transition: background 0.3s ease;
}

button:hover {
  background: #005fa3;
  cursor: pointer;
}

Multiple Properties

You can animate multiple properties at once. For example, you can fade and scale a box on hover.


.box {
  background: #f0f0f0;
  padding: 40px;
  transition: background 0.5s ease, transform 0.5s ease;
}

.box:hover {
  background: #ddd;
  transform: scale(1.05);
}

💡 Pro Tip: Combine transition with :hover and :focus for better accessibility and smoother effects on different devices.

⚠️ Common Mistake: Remember: only animatable CSS properties can be transitioned — not all CSS properties support transitions.
