Advanced capstone challenge
This final challenge asks you to write a dashboard page that combines the entire advanced level: semantic skeleton, responsive image, accessible video, complex form and a data table.
The page must include: <header>, <nav>, <main>, <aside>, <footer>; at least two <section>s inside main; one with a <picture> hero, another with a <video> and <track>; an <aside> holding a <table> (<thead>, <tbody>); a <form> at the end of main with a <fieldset> and an <output>. Add a <noscript> fallback too.
Practice Write the advanced dashboard page
Fill the <body> of the skeleton below. Inside <header> put an <h1>; inside <nav> put three <a href="#..."> links; inside <main> put two <section>s — one with a <picture> (at least one <source> and one <img>); the other with a <video controls> containing a <source> and a <track kind="captions">. At the end of main add a <form> with a <fieldset>, a <label> + <input type="range"> and an <output>Pending</output>. Inside <aside> put a <table> with <thead>, <tbody> and at least one <tr>. End the page with a <footer> and a <noscript>.

Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Which semantic tag suits a side panel (recent activity, quick links) on a dashboard?
- <aside> Correct answer
- <section>
- <article>
- <main>
Explanation: <aside> holds content related to but tangential to the main content; a side panel fits.
2 Write the noscript fallback
<main>
<section>...</section>
</main>
<____>Your browser has JavaScript off; some sections may not appear.</noscript><main>
<section>...</section>
</main>
<noscript>Your browser has JavaScript off; some sections may not appear.</noscript>Explanation: <noscript> carries the fallback content shown when scripting is off.
