缩放内容向下滚动

// 示例：使用requestAnimationFrame优化滚动动画
function smoothScrollTo(targetPosition) {
    const startPosition = window.pageYOffset;
    const distance = targetPosition - startPosition;
    const duration = 500; // 动画持续时间，单位毫秒
    let start = null;

    function step(timestamp) {
        if (!start) start = timestamp;
        const progress = timestamp - start;
        const ease = Math.min(progress / duration, 1);
        window.scrollTo(0, startPosition + distance * ease);
        if (progress < duration) {
            requestAnimationFrame(step);
        }
    }

    requestAnimationFrame(step);
}

// 示例：监听缩放事件并调整滚动位置
window.addEventListener('resize', () => {
    const zoomLevel = window.devicePixelRatio; // 获取当前缩放级别
    const targetElement = document.getElementById('focus-element');
    const elementRect = targetElement.getBoundingClientRect();
    const newScrollTop = elementRect.top * zoomLevel;
    window.scrollTo(0, newScrollTop);
});

/* 示例：针对不同设备的样式调整 */
@media (hover: none) and (pointer: coarse) {
    /* 移动设备上的样式 */
    body {
        touch-action: pan-x pan-y;
    }
}
