12.3. 选项 A：CSS

例如，尝试在 Dashboard 页面中隐藏最新的元素。第一步，您已将其 CSS 路径识别为：

#three-scale .dashboard_bubble

#three-scale .dashboard_bubble

Copy to Clipboard

Toggle word wrap

请记住，这是第二个具有相同路径的方框，因此您将使用"+"选择器。您的路径现在类似如下：

.main_layout #three-scale .dashboard_bubble + .dashboard_bubble
/* or */
.main_layout #three-scale .dashboard_bubble:nth-child(1)

.main_layout #three-scale .dashboard_bubble + .dashboard_bubble
/* or */
.main_layout #three-scale .dashboard_bubble:nth-child(1)

Copy to Clipboard

Toggle word wrap

将 display 属性改为 none 会导致这个方框不可可见：

.main_layout #three-scale .dashboard_bubble:nth-child(1) {
  display: none;
}

.main_layout #three-scale .dashboard_bubble:nth-child(1) {
  display: none;
}
