HomeWeb Front-endFront-end Q&AHow to implement a simple switch component in css

As front-end development engineers, we often need to add various switches to the page. Today, we will use CSS to implement a simple switch component for future use in our projects.

We can implement the switch in two ways. One is to use ready-made components from front-end framework libraries. The other is to write the switch yourself using HTML and CSS. We choose the latter so that we can better understand the implementation principle of the switch.

First, on the HTML page, we need to create a container that contains the switch. This container can be a div element or a fieldset element. In this container we can create two labels, one to display the status of the switch and another for the actual on/off operation.

It is very simple to implement the switch using CSS and HTML. We only need to use the input[type="checkbox"] selector to select the checkbox. Then, we can define the style of the switch through CSS styles. Here is a simple HTML code snippet:

<div>
  <label></label>
  <input>
</div>

Then, we can use CSS styles to define the style of the switch, including the state of the switch.

.switch-container {
  position: relative;
  display: inline-block;
  width: 32px;
  height: 16px;
}

/* 设置 label 元素样式 */
.switch-container label {
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  width: 16px;
  height: 16px;
  border-radius: 50%;
  background-color: #fff;
  border: 1px solid #ccc;
  box-shadow: inset 0 0 1px rgba(0, 0, 0, 0.25);
  transition: all 0.2s ease-in-out;
}

/* 设置 switch 元素样式 */
.switch-container input[type="checkbox"] {
  display: none;
}

/* 设置 label 元素 `::before` 伪元素的样式 */
.switch-container label::before {
  content: "";
  display: block;
  position: absolute;
  width: 10px;
  height: 10px;
  top: 3px;
  left: 3px;
  border-radius: 50%;
  background-color: #888;
  box-shadow: 0 0 1px rgba(0, 0, 0, 0.25);
  transition: all 0.2s ease-in-out;
}

/* 设置 switch 上下面板的样式 */
.switch-container input[type="checkbox"]:checked + label {
  border-color: #2ecc71;
  background-color: #2ecc71;
}

.switch-container input[type="checkbox"]:checked + label::before {
  transform: translateX(16px);
  background-color: #fff;
}

What does the above code snippet do? He defines a container that contains a label tag and an input[type="checkbox"] element. We then use CSS styles to define the switch's state and style. We use pseudo-elements to represent the on and off states of the switch and an animation to simulate their movement.

Here we set the colors for the on and off states, but you can customize them by changing the CSS styles. We can also add a shadow to the container, use a slider instead of a circle, and more.

Finally, you just need to add this code to your website to use the beautiful CSS switch control.

In short, it is very easy to control the state of the switch using CSS styles. This is a very simple, lightweight solution to completely customize your switch style. If you need to add toggle controls to your website, try this simple but powerful trick to gain more control over the toggle and customize it to enhance the user experience.

Sharing State Between Components Using Context and useState()Sharing State Between Components Using Context and useState()Apr 27, 2025 am 12:19 AM

Use Context and useState to share states because they simplify state management in large React applications. 1) Reduce propdrilling, 2) The code is clearer, 3) It is easier to manage global state. However, pay attention to performance overhead and debugging complexity. The rational use of Context and optimization technology can improve the efficiency and maintainability of the application.

The Impact of Incorrect Keys on React's Virtual DOM UpdatesThe Impact of Incorrect Keys on React's Virtual DOM UpdatesApr 27, 2025 am 12:19 AM

Using incorrect keys can cause performance issues and unexpected behavior in React applications. 1) The key is a unique identifier of the list item, helping React update the virtual DOM efficiently. 2) Using the same or non-unique key will cause list items to be reordered and component states to be lost. 3) Using stable and unique identifiers as keys can optimize performance and avoid full re-rendering. 4) Use tools such as ESLint to verify the correctness of the key. Proper use of keys ensures efficient and reliable React applications.

Common Mistakes to Avoid When Working with useState() in ReactCommon Mistakes to Avoid When Working with useState() in ReactApr 27, 2025 am 12:08 AM

useState is often misused in React. 1. Misunderstand the working mechanism of useState: the status will not be updated immediately after setState. 2. Error update status: SetState in function form should be used. 3. Overuse useState: Use props if necessary. 4. Ignore the dependency array of useEffect: the dependency array needs to be updated when the state changes. 5. Performance considerations: Batch updates to states and simplified state structures can improve performance. Correct understanding and use of useState can improve code efficiency and maintainability.

React's Performance Bottlenecks: Identifying and Optimizing Slow ComponentsReact's Performance Bottlenecks: Identifying and Optimizing Slow ComponentsApr 26, 2025 am 12:25 AM

React performance bottlenecks are mainly caused by inefficient rendering, unnecessary re-rendering and calculation of component internal heavy weight. 1) Use ReactDevTools to locate slow components and apply React.memo optimization. 2) Optimize useEffect to ensure that it only runs when necessary. 3) Use useMemo and useCallback for memory processing. 4) Split the large component into small components. 5) For big data lists, use virtual scrolling technology to optimize rendering. Through these methods, the performance of React applications can be significantly improved.

Alternatives to React: Exploring Other JavaScript UI Libraries and FrameworksAlternatives to React: Exploring Other JavaScript UI Libraries and FrameworksApr 26, 2025 am 12:24 AM

Someone might look for alternatives to React because of performance issues, learning curves, or exploring different UI development methods. 1) Vue.js is praised for its ease of integration and mild learning curve, suitable for small and large applications. 2) Angular is developed by Google and is suitable for large applications, with a powerful type system and dependency injection. 3) Svelte provides excellent performance and simplicity by compiling it into efficient JavaScript at build time, but its ecosystem is still growing. When choosing alternatives, they should be determined based on project needs, team experience and project size.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
