I can´t see the list in the "Preview window" even if a pass the steps

I can´t see the list in the “Preview window” even if a pass the steps in the “Learn Accessibility by Building a Quiz” section ( I,m on step 16 ). I saw part of the list behind the header before. Does anyone else see their list in the Preview or is it visible later in the coming steps?

Here is my code:

<header>
      <img id="logo" src="https://cdn.freecodecamp.org/platform/universal/fcc_primary.svg">
      <h1>HTML/CSS Quiz</h1>
      <nav>
        <ul>
          <li><a>INFO</a></li>
          <li><a>HTML</a></li>
          <li><a>CSS</a></li>
			  </ul>
      </nav>
    </header>

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Thank you and for editing my post. I missed that it is supposed to be a separate line of three backticks before or I will just use the (</>) in the editor.
