Sidebar

HTML: Sidebar

Most sites have a sidebar. It serves to display information that supplements the main text but is not obligatory. It's most often a section menu, a list of definitions from the article, widgets, etc.

In order to correctly mark up such an area, you can use the <aside> tag, within which the sidebar will be located. Let's add a sidebar with an additional menu to the example from the last lesson.

<header>
  <img src="https://cdn6.hexlet.io/1P6tmafZTIy5.png" alt="Logo"> <!-- Site Logo -->
  <nav> <!-- Menu -->
    <ul>
      <li><a href="/">Home</a></li>
      <li><a href="/about">About</a></li>
      <li><a href="/contacts">Contacts</a></li>
    </ul>
  </nav>
</header>

<aside> <!-- Sidebar -->
  <nav> <!-- Additional page menu -->
    <ul>
      <li><a href="/service-1/">Service 1</a></li>
      <li><a href="/service-2/">Service 2</a></li>
      <li><a href="/service-3/">Service 3</a></li>
    </ul>
  </nav>
</aside>

<main>
  <p>The main content of the page. This can be an article, a description of a service, data, contact information, or a form to order a service</p>

  <section class="callback-form">
    <h2>Place an order</h2>
    <form>
      <!-- Here is the service order form -->
    </form>
  </section>

  <section class="more">
    <h2>Read also</h2>
    <article class="article-block">
      <h3>Service 2</h3>
      <p>New service description</p>
      <a href="#">Service link</a>
    </article>

    <article class="article-block">
      <h3>Service 3</h3>
      <p>New service description</p>
      <a href="#">Service link</a>
    </article>

    <article class="article-block">
      <h3>Service 4</h3>
      <p>New service description</p>
      <a href="#">Service link</a>
    </article>
  </section>
</main>

Note that <aside> is contained outside of the <main> tag. This content does not have to be unique on every page. It can be unique for each specific section (if we're talking about a menu, for example). If the sidebar is unique to each page, it must be located inside the <main> tag.

Instructions

Create a website header. It should consist of 2 elements:

  • Logo
  • Navigation section. It should contain a bulleted list with two elements

Add a <main> section. Inside, create a section with a header wrapped in an <h2> tag. Inside the section, create two blocks with descriptions of new services. Don't forget that inside the <article> tag, there should be a header. Mark up the headers themselves in <article> with the <h3> tag.

Add a sidebar. It's unique to each page and contains text that applies only to that page. Insert any text inside the sidebar. Think about where exactly this area will be located

For image use following code:

Tips

  • Although we were talking about the sidebar, aside designates a complementary area. However, it often visually looks like a sidebar

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

  • Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
