What are CSS transitions and how can I animate hover effects?

Asked on Sep 11, 2025

Answer

CSS transitions allow you to smoothly change property values over a specified duration, which is perfect for animating hover effects. By defining the properties you want to animate and the duration, you can create visually appealing effects when elements are interacted with.
<!-- BEGIN COPY / PASTE -->
    <style>
      .button {
        background-color: #4CAF50;
        color: white;
        padding: 10px 20px;
        border: none;
        cursor: pointer;
        transition: background-color 0.3s ease, transform 0.3s ease;
      }

      .button:hover {
        background-color: #45a049;
        transform: scale(1.1);
      }
    </style>

    <button class="button">Hover me!</button>
    <!-- END COPY / PASTE -->
Additional Comment:
  • CSS transitions require a duration to be specified; otherwise, the change occurs instantly.
  • The "transition" property can target multiple CSS properties, separated by commas.
  • Commonly animated properties include "background-color", "transform", and "opacity".
  • Use "ease", "linear", "ease-in", "ease-out", or "ease-in-out" for different timing functions.
