Iframes and Embeds

What Is It?

An iframe shows another HTML document inside your page.

What the Tags Mean

• iframe: the embedded document.
• src: the document’s path.
• srcdoc: HTML written directly in the attribute.
• title: explains the frame to assistive tools.
• sandbox: limits what the frame can do.

Example 1

Save each example as index.html and open it in your browser. Each code block is a complete page.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Iframes and Embeds</title>
 
</head>
<body>
<iframe title="Small welcome page" srcdoc="<h1>Hello!</h1><p>This is inside a frame.</p>" sandbox></iframe>
</body>
</html>

What you see: You see a small separate page with Hello! and a sentence.

Example 2: Another Use

Use srcdoc to include a small timetable without creating a second file.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Iframes and Embeds</title>
 
</head>
<body>
<iframe title="Class timetable" srcdoc="<h1>Timetable</h1><p>Saturday at 10 am.</p>" sandbox></iframe>
</body>
</html>

Simple Tip

Use src when you have a separate file, such as timetable.html. Use srcdoc for included HTML. Always give the frame a useful title.

Try It Yourself
