How to Create an Ultra Premium Expandable Navbar with Dynamic Effects and Selection Indicator

简介

在今天的教程中，我们将逐步创建一个具有时尚设计、动态动画和现代效果的超优质可扩展导航栏。此高级导航栏具有以下功能：

高端美感的动画粒子背景。
具有悬停效果的发光图标。
突出显示活动部分的动态选择指示器。
流畅的动画和过渡，打造专业的外观。
该导航栏采用 HTML、CSS 和 JavaScript 构建，非常适合高质量 Web 界面并增强用户体验，使其成为任何项目的绝佳补充，包括《角斗士之战》等互动游戏。让我们开始吧！

第 1 步：设置 HTML 结构
我们的可扩展导航栏使用 Font Awesome 图标、切换按钮和自定义数据工具提示属性来为每个图标提供描述。这种标记为我们提供了一个灵活的构建结构。

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Expandable Premium Navbar</title>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0-beta3/css/all.min.css">
  <link rel="stylesheet" href="styles.css">
</head>
<body>

  <!-- Particle Background -->
  <div>



<p>Key HTML Elements<br>
Particle Background: Provides a subtle, animated effect behind the navbar for a high-end look.<br>
Toggle Button: Allows users to expand or collapse the navbar.<br>
Nav Items: Each item includes a tooltip, an icon, and some have notification badges.<br>
Selection Indicator: Highlights the active section with a glowing effect.<br>
Step 2: Styling the Navbar with CSS<br>
Our CSS will focus on creating a luxurious, modern design with animated background particles, hover effects, and tooltip displays. Let’s go through each part.</p>

<p>Base Styles and Background Setup<br>
</p>

<pre class="brush:php;toolbar:false">body {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  margin: 0;
  background: radial-gradient(circle, #1b1b2f, #121212);
  font-family: Arial, sans-serif;
  overflow: hidden;
  position: relative;
}

/* Particle Background */
#particle-background {
  position: absolute;
  width: 100%;
  height: 100%;
  z-index: 0;
  background: url('https://www.transparenttextures.com/patterns/dark-matter.png');
  animation: particleAnimation 30s linear infinite;
  opacity: 0.3;
}

@keyframes particleAnimation {
  0% { background-position: 0 0; }
  100% { background-position: 1000px 1000px; }
}
Navbar Styling
The navbar includes a semi-transparent background with a subtle blur effect to achieve a glassy look, which expands and collapses smoothly.

切换按钮
切换按钮可展开和折叠导航栏，并在悬停时显示旋转动画。

.toggle-button {
  display: flex;
  align-items: center;
  justify-content: center;
  font-size: 24px;
  color: #ffffff;
  cursor: pointer;
  transition: transform 0.3s ease, color 0.3s ease;
}

.toggle-button:hover {
  color: #ff00cc;
  transform: rotate(90deg);
}

导航项和工具提示效果
每个导航项都有一个带有渐变和发光背景的悬停效果。工具提示以柔和的阴影效果出现以引导用户。

.nav-item {
  position: relative;
  padding: 12px;
  font-size: 24px;
  color: #ffffff;
  cursor: pointer;
  border-radius: 15px;
  transition: all 0.3s ease;
  display: flex;
  align-items: center;
  justify-content: center;
  background: rgba(255, 255, 255, 0.2);
  backdrop-filter: blur(10px);
}

.nav-item:hover {
  background: linear-gradient(135deg, rgba(255, 0, 204, 0.4), rgba(51, 51, 255, 0.4));
  transform: translateY(-5px) scale(1.05);
}

.nav-item::before {
  content: attr(data-tooltip);
  position: absolute;
  bottom: -45px;
  left: 50%;
  transform: translateX(-50%);
  font-size: 12px;
  color: #ffffff;
  background: rgba(30, 30, 30, 0.85);
  padding: 8px 12px;
  border-radius: 8px;
  opacity: 0;
  transition: opacity 0.4s ease, transform 0.4s ease;
  pointer-events: none;
  backdrop-filter: blur(8px);
}

.nav-item:hover::before {
  opacity: 1;
  transform: translateY(-8px);
}

选择指示器和通知徽章

.selection-indicator {
  position: absolute;
  bottom: 10px;
  height: 4px;
  width: 30px;
  background: linear-gradient(90deg, #ff00cc, #3333ff);
  border-radius: 2px;
  transition: transform 0.3s ease, width 0.3s ease;
  z-index: -1;
}

/* Notification Badge */
.notification-badge {
  position: absolute;
  top: 5px;
  right: 5px;
  background: linear-gradient(45deg, #ff0000, #ff4d4d);

  box-shadow: 0px 2px 4px rgba(0, 0, 0, 0.3);

第 3 步：添加 JavaScript 以实现交互
JavaScript 控制导航栏的可展开状态、活动项目和选择指示器。它还可以在调整大小时使指示器与所选项目保持对齐。

const toggleButton = document.querySelector('.toggle-button');
const navbar = document.querySelector('.navbar');
const navItems = document.querySelectorAll('.nav-item');
const selectionIndicator = document.querySelector('.selection-indicator');

// Toggle the expanded state of the navbar
toggleButton.addEventListener('click', () => {
  navbar.classList.toggle('expanded');
  toggleButton.querySelector('i').classList.toggle('fa-bars');
  toggleButton.querySelector('i').classList.toggle('fa-times');
});

// Update selection indicator position
function updateSelectionIndicator(activeItem) {
  const itemRect = activeItem.getBoundingClientRect();
  const navbarRect = navbar.getBoundingClientRect();
  const offsetX = itemRect.left - navbarRect.left + navbar.scrollLeft;
  selectionIndicator.style.transform = `translateX(${offsetX}px)`;
  selectionIndicator.style.width = `${itemRect.width}px`;
}

// Handle nav item selection
navItems.forEach((item) => {
  item.addEventListener('click', () => {
    navItems.forEach(nav => nav.classList.remove('active'));
    item.classList.add('active');
    updateSelectionIndicator(item);
  });
});

// Initialize the position of the selection indicator on page load
document.addEventListener('DOMContentLoaded', () => {
  const activeItem = document.querySelector('.nav-item.active');
  if (activeItem) {
    updateSelectionIndicator(activeItem);
  }
});
