When I toggle preview in designer/ view my site live, the Tabs Menu and its content disappear in Safari. When clicked, the words in the Tabs Menu and the Project names (in a Slider on the Tab Pane) go away. And, the Project names (again, in a Slider in the Tab Pane) don’t transition smoothly.
Everything works fine in Chrome, so I don’t think the color of the text is just changing once it’s clicked.
