Tags describe meaning and structure. Prefer meaningful elements over generic divs when a semantic element exists.<\/p>\n<p>This topic is part of the HTML learning track. Read the example carefully, identify each important element or statement, and try changing one part at a time. Small experiments help you see cause and effect.<\/p>\n<h2>Example 1: Working code<\/h2>\n<pre class=\"dl-tutorial-code\"><code>&lt;iframe\n  src=&quot;https:\/\/example.com&quot;\n  title=&quot;Example website preview&quot;\n  loading=&quot;lazy&quot;\n  referrerpolicy=&quot;no-referrer&quot;\n  width=&quot;600&quot; height=&quot;350&quot;&gt;&lt;\/iframe&gt;<\/code><\/pre>\n<p>Save the example as <code>index.html<\/code> and open it in a browser. View Source to compare the markup with what the browser displays.<\/p>\n<h2>How to understand this example<\/h2>\n<ol>\n<li>Identify the syntax introduced by this lesson.<\/li>\n<li>Read the code from top to bottom and predict what it will do.<\/li>\n<li>Run the code, then compare the result with your prediction.<\/li>\n<li>Change one value, selector, or element and run it again.<\/li>\n<\/ol>\n<h2>Example 2: A small experiment<\/h2>\n<pre class=\"dl-tutorial-code\"><code>&lt;!-- Experiment: Iframes and Embedded Content --&gt;\n&lt;section aria-label=&quot;Practice area&quot;&gt;\n  &lt;h2&gt;Practice 14&lt;\/h2&gt;\n  &lt;p&gt;Change this content and reload your browser.&lt;\/p&gt;\n&lt;\/section&gt;<\/code><\/pre>\n<p>This second example is a practice scaffold. It is not a replacement for the main example; combine the ideas to make a small working page or script.<\/p>\n<h2>Common mistakes and best practices<\/h2>\n<ul>\n<li>Check nesting carefully: close tags in the reverse order you open them.<\/li>\n<li>Open the file in a browser and inspect the page with Developer Tools.<\/li>\n<li>Do not copy examples without understanding the result; inspect and test them.<\/li>\n<li>Prefer clear, descriptive names and simple code over unnecessary complexity.<\/li>\n<\/ul>\n<h2>Hands-on exercise<\/h2>\n<p><strong>Your task:<\/strong> Embed a trusted page and add a meaningful title.<\/p>\n<p><strong>Extra challenge:<\/strong> Improve the example for a real DevLearn student portfolio or small business website. Explain your changes in two sentences.<\/p>\n<details class=\"dl-solution\">\n<summary>Show exercise guidance<\/summary>\n<p>Start with the example above, change the heading and paragraph to satisfy the exercise, then validate the markup and test keyboard navigation.<\/p>\n<\/details>\n<h2>Quick knowledge check<\/h2>\n<ol>\n<li>What problem does iframes and embedded content solve?<\/li>\n<li>Which part of the main code example would you modify first?<\/li>\n<li>How would you test that your change works?<\/li>\n<\/ol>\n<details class=\"dl-solution\">\n<summary>Suggested answers<\/summary>\n<p>Give iframes descriptive titles and consider loading=&quot;lazy&quot; and sandbox restrictions for third-party embeds. The relevant part depends on your change; test by running the code and inspecting the result using the browser and its developer tools.<\/p>\n<\/details>\n<h2>Next steps<\/h2>\n<p>Complete the exercise without copying the solution.
