💡 Hint

Common Mistakes

Using 'show' instead of 'collapse' causes the menu to always be visible.

Using 'expand' is not a valid Bootstrap class for this purpose.

The class 'collapse' is used to hide the navigation menu on smaller screens and toggle it with the button.

Common Mistakes

Using 'show' causes the menu to be always visible.

Using 'expand' is not a valid class here.

Fill both blanks to create a responsive navigation bar that collapses on small screens and expands on large screens.

Bootsrap

<nav class="navbar navbar-[1]-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Brand</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navMenu" aria-controls="navMenu" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-[2]" id="navMenu">
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="#">Home</a>

</nav>

💡 Hint

Common Mistakes

Using 'show' instead of 'collapse' causes menu to always show.

Using 'collapse' on navbar class is incorrect.

The navbar expands on large screens with 'navbar-expand-lg' and the menu collapses with 'collapse' class.

5fill in blank

hard

Fill all three blanks to create a navigation link that is active, accessible, and uses Bootstrap classes correctly.

Bootsrap

<li class="nav-item [1]">
  <a class="nav-link" href="#" aria-current="[2]">Home <span class="sr-only">[3]</span></a>
</li>

Drag options to blanks, or click blank then click option'

Aactive

Bpage

C(current)

Ddisabled

Attempts:

3 left

💡 Hint

Common Mistakes

Omitting 'aria-current' reduces accessibility.

Using 'disabled' class instead of 'active' changes the link behavior.

The 'active' class highlights the item, 'aria-current="page"' marks it as current for screen readers, and '(current)' is visually hidden text for accessibility.
