I encountered a tricky problem when dealing with responsive design for front-end development: the layout of the website is not showing up on both phones and tablets. No matter how I adjust my CSS, I always can't fit all the devices perfectly. After trying multiple methods, I decided to use the Bootstrap 5 framework to solve this problem.

Bootstrap is a very popular front-end framework designed for developing responsive, mobile-first projects. It provides a wealth of CSS and JavaScript components to help developers quickly build beautiful and powerful web pages. By using Bootstrap, I was able to achieve a perfectly responsive layout in a short time, which greatly improved my development efficiency.

Using Composer to introduce Bootstrap is very simple, just execute the following command:

 <code class="language-bash">composer require twbs/bootstrap:5.3.3</code>

In this way, my project contains all the necessary files for Bootstrap 5, including CSS and JavaScript files. Next, I can use Bootstrap's classes and components directly in my project. For example, adding the following code can create a responsive navigation bar:

<code class="language-html"><nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a href="https://www.php.cn/link/d3509679d8747ff9cf4257cddb67f72b" rel="nofollow" target="_blank">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="https://www.php.cn/link/d3509679d8747ff9cf4257cddb67f72bnavbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a href="https://www.php.cn/link/d3509679d8747ff9cf4257cddb67f72b" rel="nofollow" target="_blank">Home</a>
        </li>
        <li class="nav-item">
          <a href="https://www.php.cn/link/d3509679d8747ff9cf4257cddb67f72b" rel="nofollow" target="_blank">Features</a>
        </li>
        <li class="nav-item">
          <a href="https://www.php.cn/link/d3509679d8747ff9cf4257cddb67f72b" rel="nofollow" target="_blank">Pricing</a>
        </li>
        <li class="nav-item">
          <a href="https://www.php.cn/link/d3509679d8747ff9cf4257cddb67f72b" rel="nofollow" target="_blank">Disabled</a>
        </li>
      </ul>
    </div>
  </div>
</nav></code>

By using Bootstrap, my website not only displays very well on desktop devices, but also on phones and tablets. This not only solved my responsive design problem, but also allowed me to focus on other development tasks and improved overall development efficiency.

Overall, introducing the Bootstrap 5 framework using Composer is a very wise choice. It not only solved my practical problems, but also provided a wealth of components and tools, greatly simplifying my front-end development efforts.
