Tutorial on using CSS to implement a responsive sliding menu, specific code examples are required

In modern web design, responsive design has become an essential skill. To accommodate different devices and screen sizes, we need to add a responsive menu to the website. Today, we will use CSS to implement a responsive sliding menu and provide you with specific code examples.

First, let’s take a look at the implementation effect. We will create a navigation bar that automatically collapses when the screen width is smaller than a certain threshold and expands by clicking the menu button. This will enable users to browse our website conveniently on small screens.

HTML structure:

<nav class="menu">
  <input class="menu__toggle" type="checkbox">
  <ul class="menu__items">
    <li class="menu__item"><a href="#">首页</a></li>
    <li class="menu__item"><a href="#">关于我们</a></li>
    <li class="menu__item"><a href="#">产品</a></li>
    <li class="menu__item"><a href="#">联系我们</a></li>
  </ul>
  <label class="menu__button" for="menu-toggle"></label>
</nav>

CSS style:

.menu {
  position: relative;
  display: flex;
  align-items: center;
  justify-content: space-between;
  background-color: #f1f1f1;
  padding: 10px;
}

.menu__toggle {
  display: none;
}

.menu__items {
  list-style: none;
  margin: 0;
  padding: 0;
  display: flex;
}

.menu__item {
  margin-right: 10px;
}

.menu__item:last-child {
  margin-right: 0;
}

.menu__item a {
  text-decoration: none;
  color: #333;
  padding: 5px;
}

.menu__button {
  width: 30px;
  height: 30px;
  background-color: #333;
  position: relative;
  cursor: pointer;
  display: none;
}

.menu__button::after,
.menu__button::before {
  content: '';
  position: absolute;
  width: 20px;
  height: 2px;
  background-color: #fff;
  top: 50%;
  left: 50%;
  margin-top: -1px;
  margin-left: -10px;
}

.menu__button::before {
  transform: translateY(-6px);
}

.menu__button::after {
  transform: translateY(6px);
}

In the above code, we use some basic CSS properties and selectors to implement a responsive sliding menu. Let's analyze these codes one by one.

First, we add a container with the class name menu for the navigation bar. This container is used to wrap the entire navigation bar and set some basic styles, such as background color and padding.

Secondly, we added a checkbox to control the expansion and collapse of the menu. This checkbox is hidden by default, and when we click the menu button, it will be selected, causing the menu item to appear.

Then we added an unordered list of menu items and styled it. We use flex layout to arrange the menu items horizontally, and set some spacing and styles.

Finally, we styled the menu button. Here we use a pseudo element to style the button, and use absolute positioning to place the pseudo element in the center of the button. After clicking the button, the menu items will expand.

The above is a simple tutorial on using CSS to implement a responsive sliding menu. By applying CSS properties and selectors flexibly, we can easily create a responsive menu that adapts to different screen sizes. Hope this tutorial is helpful!
