如何围绕浮动操作按钮创建带可点击工具提示的弧形图标组

一、改造为弧形环绕布局 #

通过调整定位与CSS变换，让四个子按钮以主按钮为中心呈弧形排列：

• 将.adminButtons设置为绝对定位，以主按钮的右下角为变换原点
• 为每个子按钮设置初始位置，展开时通过rotate与translate组合实现弧形位移
• 保留原有过渡延迟，维持展开的层次感

二、实现可点击Tooltip #

利用CSS伪元素实现悬停提示，同时保证提示区域可点击：

• 给每个子按钮添加data-tooltip属性存储提示文本
• 使用:before伪元素创建提示容器，默认隐藏，悬停时显示
• 添加箭头样式增强提示的指向性，确保提示跟随按钮位置
