Step-by-Step Guide to Building an IFrame Builder
1. Set Up the Basic HTML Structure
Start with an HTML form where users can input the URL and customize iframe settings.
<form id="iframeForm">
<label for="iframeURL">Enter URL:</label>
<input type="text" id="iframeURL" placeholder="https://example.com" required>
<label for="width">Width:</label>
<input type="text" id="width" value="600">
<label for="height">Height:</label>
<input type="text" id="height" value="400">
<button type="button" onclick="generateIframe()">Generate IFrame</button>
</form>
2. Write the JavaScript Function
Create a JavaScript function to generate the iframe dynamically.
function generateIframe() {
var url = document.getElementById('iframeURL').value;
var width = document.getElementById('width').value;
var height = document.getElementById('height').value;
var iframeCode = '<iframe src="' + url + '" width="' + width + '" height="' + height + '" frameborder="0" allowfullscreen></iframe>';
document.getElementById('output').innerHTML = iframeCode;
}
3. Optimize for SEO
- Use the lazy loading attribute to improve page speed.
