<template>

Syntax

<template id="my-template">
  <p>Reusable content</p>
</template>

Examples

<template id="card-template">
  <div class="card">
    <h3></h3>
    <p></p>
  </div>
</template>

<template id="item-template">
  <li class="item"></li>
</template>
<ul id="list"></ul>

<script>
  const tpl = document.getElementById('item-template');
  const list = document.getElementById('list');
  ['HTML', 'CSS', 'JS'].forEach(text => {
    const clone = tpl.content.cloneNode(true);
    clone.querySelector('.item').textContent = text;
    list.appendChild(clone);
  });
</script>

Best practices

• Use template for markup that will be cloned and reused multiple times via JavaScript, like list items or cards
• Remember that content inside a template is inert — access it via the element's .content property, not by querying it directly
• Prefer template over building HTML strings with string concatenation or innerHTML for repeated UI patterns
• Combine with document.importNode or cloneNode(true) to insert a copy without mutating the original template
