导航栏展开后名称动画遮挡导航按钮问题求助

问题原因 #

导航栏打开后无法点击按钮，是因为名称动画#name_shine的堆叠层级高于导航栏：

• #name_shine使用position: relative，且在DOM结构中位于导航元素之后，默认堆叠优先级更高
• 导航容器.wrapper虽为固定定位，但未显式设置z-index，被上方的动画文本完全遮挡，导致点击事件无法触发

解决方案 #

给导航容器设置更高的z-index，确保其堆叠在名称动画上方，只需修改一处CSS：

在.wrapper的样式中添加z-index: 10：

.wrapper{
  position: fixed;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  background: linear-gradient(-135deg, #000000, #ffffff);
  clip-path: circle(25px at calc(100% - 45px) 45px);
  transition: all 0.3s ease-in-out;
  z-index: 10; /* 新增这一行 */
}

原理说明 #

CSS堆叠上下文由position（非static值）和z-index共同控制。给.wrapper设置z-index:10后，其堆叠层级会高于默认层级的#name_shine，导航按钮就能正常接收点击事件。
