HTML, CSS and jQuery: Build a beautiful login and registration interface

As web developers, we often need to build user login and registration interfaces. A beautiful, user-friendly login and registration interface is crucial to improving user experience and website image. In this article, we will use HTML, CSS and jQuery to build a beautiful login registration interface and provide specific code examples.

First, we need to create an HTML document and define two forms for login and registration. We can build these two forms using form elements and some input fields. The following is a simple example:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <div class="container">
    <h1 id="Login">Login</h1>
    <form id="loginForm">
      <input type="text" placeholder="Username">
      <input type="password" placeholder="Password">
      <button type="submit">Login</button>
    </form>

    <h1 id="Register">Register</h1>
    <form id="registerForm">
      <input type="text" placeholder="Username">
      <input type="password" placeholder="Password">
      <input type="password" placeholder="Confirm Password">
      <button type="submit">Register</button>
    </form>
  </div>

  <script src="jquery.min.js"></script>
  <script src="script.js"></script>
</body>
</html>

Next, we create a CSS file to beautify our login registration interface. We can use CSS to define style, layout and animation effects. Here is a simple example:

.container {
  width: 400px;
  margin: 0 auto;
  text-align: center;
}

form {
  margin-top: 20px;
}

h1 {
  margin-bottom: 10px;
}

button {
  padding: 10px 20px;
  background-color: #4CAF50;
  color: white;
  border: none;
  cursor: pointer;
}

button:hover {
  opacity: 0.8;
}

input {
  margin-bottom: 10px;
  padding: 10px;
  width: 100%;
}

Now, we need to use jQuery to add some interactive effects and validation functionality. We can use jQuery's event handlers and selectors to achieve these functions. The following is a simple example:

$(document).ready(function() {
  $("#loginForm").submit(function(e) {
    e.preventDefault(); // 阻止表单提交的默认行为

    // 获取输入的用户名和密码
    var username = $("#loginForm input[type='text']").val();
    var password = $("#loginForm input[type='password']").val();

    // 在这里添加登录验证的逻辑
    // ...

    // 清空输入字段
    $("#loginForm input").val("");
  });

  $("#registerForm").submit(function(e) {
    e.preventDefault(); // 阻止表单提交的默认行为

    // 获取输入的用户名、密码和确认密码
    var username = $("#registerForm input[type='text']").val();
    var password = $("#registerForm input[type='password']").val();
    var confirmPassword = $("#registerForm input[type='password']:last").val();

    // 在这里添加注册验证的逻辑
    // ...

    // 清空输入字段
    $("#registerForm input").val("");
  });
});

In the above code, we use the submit() event and preventDefault() method to prevent the form's default submission behavior. Then, we use the selector and val() method to get the input value in the form. Next, we can add validation logic and other custom functionality to these two event handlers.

Finally, we need to bring in jQuery and our CSS file and add the corresponding link in the HTML. We can introduce jQuery by downloading the jQuery library from the jQuery official website and saving it in the project.

With the above code examples of HTML, CSS and jQuery, we can build a beautiful, user-friendly login and registration interface, and add interactive effects and verification functions. This will provide users with a good experience while also improving the image and usability of the website.

It should be noted that the above example is just a simple beginning and you can expand and customize it according to your own needs. I hope this article will help you build a beautiful login and registration interface!

The Relationship Between JavaScript, C , and BrowsersMay 01, 2025 am 12:06 AM

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js Streams with TypeScriptApr 30, 2025 am 08:22 AM

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

Python vs. JavaScript: Performance and Efficiency ConsiderationsApr 30, 2025 am 12:08 AM

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

The Origins of JavaScript: Exploring Its Implementation LanguageApr 29, 2025 am 12:51 AM

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

Behind the Scenes: What Language Powers JavaScript?Apr 28, 2025 am 12:01 AM

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The Future of Python and JavaScript: Trends and PredictionsApr 27, 2025 am 12:21 AM

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Python vs. JavaScript: Development Environments and ToolsApr 26, 2025 am 12:09 AM

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Is JavaScript Written in C? Examining the EvidenceApr 25, 2025 am 12:15 AM

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.
