1. Bootstrap framework

Bootstrap is a very popular CSS framework. It provides a rich set of components and styles that can easily build modern web pages. The following is a sample code that shows how to use Bootstrap to create a simple navigation bar:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Logo</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" 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 active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Disabled</a>
      </li>

In the above code, we implement the style of the navigation bar by using the class name provided by Bootstrap. For example, the .navbar class is used to define the style of the navigation bar container, the .navbar-expand-lg class is used to define the way the navigation bar is displayed on a large screen, . The navbar-light class is used to define the light theme of the navigation bar. In addition, there are many other classes that can help us achieve more style effects.

<button class="button">Default Button</button>
<button class="success button">Success Button</button>
<button class="alert button">Alert Button</button>
<button class="secondary button">Secondary Button</button>

In the above code, we can achieve different style effects by adding different class names to the button elements. For example, the .button class is used to define the basic style of the button, the .success class is used to define the button style of the success state, and the .alert class is used to define the warning The button style of the state, the .secondary class is used to define the button of the secondary style.
