1. CSS-Based Effects

CSS is a powerful tool for creating visual effects and animations. It offers excellent performance and is well-supported across modern browsers. Common CSS techniques for character card selection effects include:

Hover Effects: Use the :hover pseudo-class to apply styles when the user hovers over a card (e.g., changing the background color, adding a shadow, or scaling the card).
Transition Effects: Use the transition property to create smooth animations between different states (e.g., when hovering or selecting a card).
Transformations: Use the transform property to scale, rotate, or translate cards, adding dynamic visual effects.
Keyframe Animations: Use @keyframes to create more complex animations, such as pulsating glows or animated borders.

Example CSS for a simple hover effect:

.character-card {
  background-color: #f0f0f0;
  transition: background-color 0.3s ease;
}

.character-card:hover {
  background-color: #e0e0e0;
}

2. JavaScript-Based Effects

JavaScript provides greater flexibility and control over animations and interactions. It can be used to create more complex effects that are difficult to achieve with CSS alone. Common JavaScript techniques include:

Event Listeners: Use event listeners (e.g., click, mouseover, mouseout) to trigger animations and style changes.
DOM Manipulation: Modify the DOM to add, remove, or update elements and styles dynamically.
Animation Libraries: Use libraries like GreenSock Animation Platform (GSAP) or Anime.js to simplify the creation of complex animations.

Example JavaScript for adding a selected class:

const cards = document.querySelectorAll('.character-card');

cards.forEach(card => {
  card.addEventListener('click', () => {
    // Remove 'selected' class from all cards
    cards.forEach(c => c.classList.remove('selected'));
    // Add 'selected' class to the clicked card
    card.classList.add('selected');
  });
});

3. Combination of CSS and JavaScript

In many cases, the best approach is to combine CSS and JavaScript to leverage the strengths of both technologies. CSS can handle simple animations and transitions, while JavaScript can handle more complex interactions and dynamic effects.

For example, you might use CSS for hover effects and transitions, while using JavaScript to handle the selection logic and add or remove classes dynamically.

Cross-Browser Compatibility: Libraries handle cross-browser compatibility issues, ensuring consistent animations across different browsers.
Performance Optimization: Libraries are optimized for performance, providing smooth animations without performance bottlenecks.
Advanced Features: Libraries offer advanced features like timelines, easing functions, and more, enabling the creation of sophisticated animations.

Example using GSAP to animate card selection:

import gsap from 'gsap';

const cards = document.querySelectorAll('.character-card');

cards.forEach(card => {
  card.addEventListener('click', () => {
    // Remove 'selected' class from all cards
    cards.forEach(c => c.classList.remove('selected'));
    // Add 'selected' class to the clicked card
    card.classList.add('selected');

    // Animate the selected card
    gsap.to(card, {
      duration: 0.3,
      scale: 1.1,
      yoyo: true,
      repeat: 1,
      ease: 'power1.inOut',
    });
  });
});

  background-origin: border-box;
  background-clip: content-box, border-box;
  animation: border-animation 2s linear infinite;
}

@keyframes border-animation {
  0% {
    background-position: 0 0;
  }
  100% {
    background-position: 100% 0;
  }
}

4. Flip Effect

A flip effect can be used to reveal additional information about the character when the card is selected. This can be implemented using CSS transformations and transitions.

.character-card {
  transition: transform 0.5s ease;
  transform-style: preserve-3d;
}

.character-card.selected {
  transform: rotateY(180deg);
}

.character-card-front,
.character-card-back {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  backface-visibility: hidden;
}

.character-card-back {
  transform: rotateY(180deg);
}
