非推奨の SMIL アニメーションを CSS または Web アニメーションに置き換えるにはどうすればよいですか?

<code class="css">.element_tpl:hover {
    stroke-opacity: 0.5;
}</code>

<code class="css">@keyframes scale-animation {
    0% { transform: scale(1); }
    50% { transform: scale(1.12); }
    100% { transform: scale(1); }
}</code>

<code class="css">.element_tpl {
    animation: scale-animation 0.5s infinite alternate;
}</code>

<code class="javascript">// Create a new animation
const animation = document.timeline.addAnimation();

// Define keyframes
const keyframes = [
    { transform: 'scale(1)', offset: 0 },
    { transform: 'scale(1.12)', offset: 0.5 },
    { transform: 'scale(1)', offset: 1 }
];

// Apply keyframes to the animation
animation.effect = keyframes;

// Target the element
animation.target = document.querySelector('.element_tpl');</code>

<code class="css">.element_tpl {
    transition: transform 0.2s;
}

.element_tpl:active {
    transform: scale(1.1);
}</code>

<code class="javascript">// Add event listener
document.querySelector('.element_tpl').addEventListener('click', (event) => {

    // Create a new animation
    const animation = document.timeline.addAnimation();

    // Define keyframes
    const keyframes = [
        { transform: 'scale(1)', offset: 0 },
        { transform: 'scale(1.1)', offset: 0.2 },
        { transform: 'scale(1)', offset: 0.4 },
