HTML, CSS and jQuery: Making an interface with a notification pop-up window

Introduction:
In modern web design, notification pop-up windows are a A very common element. It can be used to display important information to users or prompt users to perform some operations. This article will introduce how to use HTML, CSS and jQuery to create an interface with a notification pop-up window, and attach specific code examples.

1. HTML structure
First, we need to use HTML to build the basic structure of the page. The following is an example of the HTML code required for the notification pop-up window:

<!DOCTYPE html>
<html>
<head>
    <title>通知弹窗示例</title>
    <link rel="stylesheet" type="text/css" href="style.css">
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script src="script.js"></script>
</head>
<body>
    <h1 id="通知弹窗示例">通知弹窗示例</h1>
    <button id="showNotification">显示通知</button>

    <div id="notificationContainer">
        <div id="notificationContent">
            <p id="notificationMessage"></p>
            <button id="closeNotification">关闭</button>
        </div>
    </div>
</body>
</html>

In this example, we use an h1 tag to display the title of the page and add a button to trigger the display of the notification pop-up window. The notification pop-up window itself is a div element located within the notificationContainer container and contains a p element that displays the notification content and a close button.

2. CSS Style
Next, we need to use CSS to beautify the appearance of the notification pop-up window. The following is a relevant CSS code example:

#notificationContainer {
    position: fixed;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    background-color: #fff;
    border-radius: 5px;
    padding: 20px;
    box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
    display: none;
}

#notificationContent {
    text-align: center;
}

#notificationMessage {
    font-size: 18px;
    margin-bottom: 10px;
}

#closeNotification {
    background-color: #007bff;
    color: #fff;
    border: none;
    border-radius: 5px;
    padding: 10px 20px;
    cursor: pointer;
}

#closeNotification:hover {
    background-color: #0056b3;
}

In this example, we set the container (notificationContainer) of the notification pop-up window to a fixed position, so that it is located in the center of the page vertically and horizontally. We also set some basic styles, such as background color, rounded corners, shadow, etc. The text of the notification content (notificationContent) is centered and aligned, and some text and button styles are set.

3. jQuery interaction
Finally, we need to use jQuery to realize the interaction of notification pop-up windows. The following is a relevant JavaScript code example:

$(document).ready(function() {
    $("#showNotification").click(function() {
        $("#notificationContainer").fadeIn();
    });

    $("#closeNotification").click(function() {
        $("#notificationContainer").fadeOut();
    });
});

In this example, we use the .ready() function to ensure that the relevant code is executed after the page is loaded. When the button that displays the notification (showNotification) is clicked, we use the .fadeIn() function to display the notification pop-up window. When the close button (closeNotification) is clicked, we use the .fadeOut() function to hide the notification pop-up window.

Summary:
Through the cooperation of HTML, CSS and jQuery, we can easily create an interface with a notification pop-up window. Notification pop-ups can be used to display important information to users or prompt users to perform some operations. I hope the sample code in this article can help readers better understand and apply these technologies.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
