HTML <template> Tag

What is HTML <template> Tag?

The HTML template tag is used to define HTML content that is not displayed immediately when a page loads. It acts as a hidden container for reusable HTML code that can be dynamically inserted into the page later using JavaScript. This tag is useful for creating reusable components such as cards, forms, lists, or layouts that appear only when needed. Developers often use it for dynamic applications and interactive websites. The content inside the template tag remains inactive until it is accessed through a script. It is an essential part of modern web development because it helps keep HTML structure clean, improves performance, and allows code reuse.

Syntax of the HTML <template> Tag

plaintext
<template>
  <!-- HTML content goes here --> </template>

The template tag starts with <template> and ends with </template>. Any HTML code written inside will not be rendered until activated by JavaScript.

Examples of HTML <template> Tag

Example 1: Basic HTML Template Tag

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

<template id="welcomeMessage">
  <h2>Welcome to Scholar247!</h2>
  <p>This message is loaded dynamically using the HTML template tag.</p>
</template>

<script>
  const template = document.getElementById("welcomeMessage");
  const clone = template.content.cloneNode(true);
  document.body.appendChild(clone);
</script>

</body>
</html>

Explanation:
In this example, the content inside the HTML template tag is hidden at first. When the JavaScript runs, it copies the template content and adds it to the webpage. The message “Welcome to Scholar247!” is then displayed dynamically.
