每天一個CSS小樣式：炫酷的流光按鈕詳情 - ci,4s,CSS,Java,後端開發 CodePulse代碼脈搏博客

今天我們來創建一個炫酷的流光按鈕效果，它會隨着鼠標移動產生動態的流光和陰影效果。這個效果結合了CSS漸變、動畫和偽元素技術。
實現思路

使用linear-gradient創建漸變背景
通過::before偽元素實現流光效果
使用CSS動畫實現流光移動
添加懸停和點擊交互效果
結合JavaScript實現鼠標跟隨效果

效果説明

這個頁面展示了四種不同風格的流光按鈕：
基礎流光按鈕：具有動態漸變背景，懸停時背景動畫和白色流光劃過效果
鼠標跟隨流光：懸停時顯示漸變邊框和背景，具有流光效果
3D流光按鈕：具有3D旋轉效果，懸停時按鈕傾斜並有光澤劃過
霓虹流光按鈕：霓虹燈風格，懸停時變色發光，並有流光劃過
技術要點

使用linear-gradient創建多彩漸變背景
通過background-size放大背景，再通過動畫移動背景位置實現流光效果
利用::before和::after偽元素添加額外的視覺效果
使用transform屬性實現3D效果和動畫
結合box-shadow創建發光和立體效果
使用CSS動畫和過渡實現平滑的交互效果
每個按鈕都是純CSS實現，只有簡單的JavaScript用於增強交互體驗（如點擊漣漪效果）。
