Introduction to HTML Templates
HTML templates are pre-defined HTML structures that you can use to create web pages quickly and consistently. Think of them as reusable pieces of code that help you avoid writing the same HTML over and over again. This is especially useful when you’re working on larger projects or sites that require a uniform look and feel.
Key Terminology
- Template: A pre-designed HTML structure that can be reused.
- Placeholder: A variable or marker in a template that gets replaced with actual content.
- Static Content: Content that doesn’t change across different uses of the template.
- Dynamic Content: Content that changes based on user input or other variables.
Simple Example: The Basic Template
<!DOCTYPE html>
<html>
<head>
<title>My First Template</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a simple HTML template.</p>
</body>
</html>This is a basic HTML template. It includes a title and a simple body with a header and a paragraph. You can use this as a starting point for any web page.
Progressively Complex Examples
Example 1: Adding Placeholders
<!DOCTYPE html>
<html>
<head>
<title>{{pageTitle}}</title>
</head>
<body>
<h1>{{header}}</h1>
<p>{{content}}</p>
</body>
</html>In this example, we’ve added placeholders like {{pageTitle}}, {{header}}, and {{content}}. These will be replaced with actual content when the template is used.
Example 2: Using JavaScript for Dynamic Content
<!DOCTYPE html>
<html>
<head>
<title>Dynamic Template</title>
<script>
function loadContent() {
document.getElementById('header').innerText = 'Hello, World!';
document.getElementById('content').innerText = 'This content is dynamic!';
}
</script>
</head>
<body onload="loadContent()">
<h1 id="header"></h1>
<p id="content"></p>
</body>
</html>Here, we’re using JavaScript to dynamically set the content of the header and paragraph when the page loads. This is a simple way to make your templates more interactive.
Example 3: Advanced Template with CSS and JavaScript
<!DOCTYPE html>
<html>
<head>
<title>Advanced Template</title>
<style>
body { font-family: Arial, sans-serif; }
.highlight { color: blue; }
</style>
<script>
function updateContent() {
document.querySelector('.highlight').innerText = 'Updated Content!';
}
</script>
</head>
<body>
<h1 class="highlight">Original Content</h1>
<button onclick="updateContent()">Change Content</button>
</body>
</html>This example combines HTML, CSS, and JavaScript. The CSS styles the text, and JavaScript updates the content when the button is clicked. This demonstrates how templates can be both styled and interactive.
