Navigating to different sections of a single page using Bootstrap

I'm feeling a bit lost when it comes to understanding how linking to an element within a page functions. As I delve into the starter template for Twitter Bootstrap, I encounter the following code snippet in the navbar:

<ul class="nav navbar-nav">
    <li class="active"><a href="#">Home</a></li>
    <li><a href="#about">About</a></li>
    <li><a href="#contact">Contact</a></li>
</ul>

It seems clear that there are anchor tags to #about and #contact within the list elements, but where is the actual content defined? In the provided example site, the .starter-template div remains constant regardless of which navbar button is clicked. How can I alter the div upon clicking a navbar button? I attempted the following, resulting in just generating a large link as expected:

<a name="about">
    <div class="container">
        <div class="starter-template">
            <h1>About.</h1>
                <p class="lead">#about</p>
        </div>
    </div>
</a>

Your guidance would be greatly appreciated!

Placeholder links are used in web development to create navigation within a page. If you wish to keep the placeholders such as #about, you must define an element on your webpage with that specific ID. For instance, you can make a longer page and include the following tag:

<h1 id="about">Here's the About Content</h1>

By clicking on the placeholder link, the page will jump to the designated spot automatically.

Wikipedia adopts this technique to direct users to different sections within an article. You can examine how they use the <span> tag for "See Also" by visiting the link:

http://en.wikipedia.org/wiki/Twitter_Bootstrap#See_also

While these placeholders come pre-filled in the Bootstrap template, the intention is for you to customize them with your desired links. For example, if you want to add a link to Yahoo, you would input your own HREF like this:

<a href="http://www.yahoo.com">Yahoo</a>

You have the flexibility to target any other link within your site using this method.

Remember, these placeholders require corresponding pages at the URLs they point to in order to work effectively. Hash links may operate differently when developing a Single-page Application (SPA), but the main concept remains the same - an existing element with the specified ID is necessary for the link to function properly within the page.

This functionality is inherent in HTML and not exclusive to utilizing Bootstrap.
