HTML, CSS and jQuery: Build a beautiful scrolling tab navigation
In modern web design, scrolling tab navigation has become a common design element. It provides visitors with easy navigation and increases the interactivity of the web page. This article will introduce how to use HTML, CSS and jQuery to build a beautiful scrolling tab navigation, and provide specific code examples.
First, we need to understand the basic structure of HTML. Here is a simple HTML code example:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>滚动标签导航</title> <link rel="stylesheet" href="style.css"> </head> <body> <nav> <ul> <li><a href="#section1">Section 1</a></li> <li><a href="#section2">Section 2</a></li> <li><a href="#section3">Section 3</a></li> <li><a href="#section4">Section 4</a></li> </ul> </nav> <section id="section1"> <h1 id="Section">Section 1</h1> <p>This is the content of section 1.</p> </section> <section id="section2"> <h1 id="Section">Section 2</h1> <p>This is the content of section 2.</p> </section> <section id="section3"> <h1 id="Section">Section 3</h1> <p>This is the content of section 3.</p> </section> <section id="section4"> <h1 id="Section">Section 4</h1> <p>This is the content of section 4.</p> </section> <script src="jquery.min.js"></script> <script src="script.js"></script> </body> </html>
In the above code, we use the <nav></nav>
element to contain our navigation menu, using <ul> The </ul>
and <li>
elements are used to create the list items of the navigation menu. Each list item is a link (<a></a>
) to the corresponding section (<section></section>
) of the page. Please note that each section is identified using a unique id attribute.
Next, we need to style the navigation menu in CSS. Here is a simple CSS code example:
nav { position: fixed; top: 0; left: 0; width: 100%; background-color: #333; padding: 10px 0; z-index: 999; } nav ul { display: flex; justify-content: center; list-style-type: none; margin: 0; padding: 0; } nav ul li { margin: 0 10px; } nav ul li a { color: #fff; text-decoration: none; padding: 5px; } nav ul li a.active { border-bottom: 2px solid #fff; }
In this example, we use some basic CSS styles to set the appearance of the navigation menu. By setting position: fixed
, we fix the navigation menu to the top of the page. We also used flex
layout to center the navigation menu list items horizontally and add some spacing to them.
Now we will use jQuery to add some interactive functionality. The following is a simple jQuery code example:
$(document).ready(function() { $(window).scroll(function() { var scrollPos = $(window).scrollTop(); $('section').each(function() { var offsetTop = $(this).offset().top - 50; var sectionHeight = $(this).outerHeight(); var sectionId = $(this).attr('id'); if (scrollPos >= offsetTop && scrollPos < (offsetTop + sectionHeight)) { $('nav ul li a').removeClass('active'); $('nav ul li a[href="#' + sectionId + '"]').addClass('active'); } }); }); });
In this code, we use the scroll
event to listen for scroll events. When scrolling occurs, we iterate through each <section></section>
element and determine the currently active section based on the scroll position. By using the offset()
method to get the top position of each section, combined with the scrollTop()
method to get the current scroll position, we can determine which section is in the viewport. Once the active sections are identified, we will add an active
class to the corresponding navigation link to highlight it.
Now, we have built a nice scrolling tab navigation. As the user scrolls the page, the navigation menu automatically updates and displays the currently active section. I hope this code example is helpful and helps you build better web designs!

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.

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.

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 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.

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.

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.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.
