实现基于用户偏好的网页动态样式主要涉及以下几个基础概念和技术:
以下是一个简单的示例,展示如何使用JavaScript和LocalStorage实现主题切换功能:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Dynamic Styles</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<button id="theme-toggle">Toggle Theme</button>
<script src="script.js"></script>
</body>
</html>
body {
transition: background-color 0.3s, color 0.3s;
}
.dark-theme {
background-color: #121212;
color: #ffffff;
}
.light-theme {
background-color: #ffffff;
color: #000000;
}
document.addEventListener('DOMContentLoaded', () => {
const toggleButton = document.getElementById('theme-toggle');
const currentTheme = localStorage.getItem('theme') || 'light-theme';
if (currentTheme === 'dark-theme') {
document.body.classList.add('dark-theme');
} else {
document.body.classList.add('light-theme');
}
toggleButton.addEventListener('click', () => {
document.body.classList.remove(currentTheme);
currentTheme = currentTheme === 'dark-theme' ? 'light-theme' : 'dark-theme';
document.body.classList.add(currentTheme);
localStorage.setItem('theme', currentTheme);
});
});
通过以上方法,你可以实现一个基于用户偏好的网页动态样式系统,提升用户体验和个性化需求。
