How to use CSS Transitions and Animations in the webpage?

Question

Ravi Vishwakarma · Answer

Transitions and animations are two powerful features in CSS that enable web developers to add dynamic effects and interactivity to their web pages. While both are used to achieve similar results—creating movement and changes in appearance—they differ in how they are implemented and the level of control they offer.
CSS Transitions:
Definition: CSS transitions allow you to smoothly change the values of CSS properties over a specified duration.
Key Concepts:
Properties: Transitions are applied to specific CSS properties (e.g.,
color, background-color, opacity).Duration: You can define how long the transition takes to complete using the
transition-duration property.Timing Function: Specifies the speed curve of the transition, controlling how intermediate values are calculated. Common timing functions include
ease, linear, ease-in, ease-out, and
ease-in-out.Trigger: Transitions are typically triggered by a change in state, such as
:hover, :focus, or through JavaScript events.
Syntax :
/* Define transition on an element */
.element {
    transition: property duration timing-function delay;
}
/* Apply changes to trigger the transition */
.element:hover {
    property: new-value;
}
Example:
.button {
    transition: background-color 0.3s ease;
}
.button:hover {
    background-color: red;
}
CSS Animations:
Definition: CSS animations allow you to create more complex and dynamic effects by defining keyframes and applying them to elements.
Key Concepts:
Keyframes: Keyframes define the stages of the animation and the properties that should be animated at each stage.Animation Properties: You can specify various animation properties, including the animation name, duration, timing function, delay, iteration count, direction, and fill mode.Iteration Count: Determines how many times the animation should repeat, including values like
infinite for continuous looping.Direction: Specifies whether the animation should play forwards, backwards, or alternate between forwards and backwards.Fill Mode: Defines how the element's styles should be applied before and after the animation plays.
Syntax:
/* Define keyframes */
@keyframes animation-name {
    0% { /* Start state */ }
    100% { /* End state */ }
}
/* Apply animation to an element */
.element {
    animation: animation-name duration timing-function delay iteration-count direction fill-mode;
}
Example:
@keyframes color-change {
    0% { background-color: blue; }
    50% { background-color: red; }
    100% { background-color: green; }
}
.box {
    animation: color-change 2s ease-in-out infinite alternate;
}
Tips for Usage:
Start with Simple Transitions: Start by using transitions for simple effects like hover states or link styles.Experiment with Animations: Once you're comfortable with transitions, experiment with animations to create more complex and dynamic effects.Use Vendor Prefixes: To ensure compatibility with older browsers, include vendor prefixes (-webkit-, -moz-, -o-) for animations and transitions.Performance Considerations: Be mindful of performance when using animations, especially on mobile devices. Avoid heavy animations that may cause lag or affect user experience negatively.Accessibility: Ensure that animated elements are still accessible to users with disabilities by providing alternative ways to access content or navigate the site.
Differences:
Control: Transitions offer simple control over property changes, while animations provide more granular control through keyframes.Complexity: Animations are more flexible and allow for more complex effects, making them suitable for intricate animations.Trigger: Transitions are typically triggered by changes in state, while animations can be triggered automatically or through user interaction.
