Navigation bar expansion issue in Boostrap needs fixing

Hello, currently I am in the process of creating my portfolio website. This is my first time working with bootstrap so I am still figuring things out. Right now, I am trying to create a navbar that expands using navbar-expand, but for some reason it's only displaying the collapsed version and the button appears transparent. Any assistance would be greatly appreciated. Below is my HTML code:

<header>
<div class="container-fluid"
 <nav class="navbar navbar-expand-lg navbar-light bg-light" style="background-color: #bdd4f9;">
  <a class="navbar-brand" href="index.html">Name Here</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#myNav" aria-controls="myNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="myNav">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="index.html">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="experience.html">Professional Experience</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="samples.html">Work Samples</a>
      </li>
        </div>
      </li>
    </ul>
</nav>

Answer №1

To provide a clearer explanation of what Bootstrap does: Bootstrap offers tools that enable the author to style html elements in different ways based on screen sizes. For example, .navbar-expand-lg behaves differently from .navbar-expand-sm. If you want the navigation menu to always be expanded, just use .navbar-expand without any size-specific suffixes.

In the sample code on its Navbar documentation page, Bootstrap uses .navbar-expand-lg, but also mentions that

Navbars need a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl} for responsive collapsing and color scheme classes.

You can add {-sm|-md|-lg|-xl} depending on when you want the navbar to stop expanding and start stacking vertically. This approach is common in Bootstrap as there are numerous customizable classes tailored for various mobile responsive breakpoints, so keep in mind that styling may need adjustments to achieve the desired level of responsiveness.
