Dygraph text is visible through jQuery Datepicker

Question

I have Dygraph on my page, and a jQuery Datepicker to select the date range to be loaded into the Dygraph. When the data input box is clicked, the date picker pops up so the user can select a date range. In the section of the html I loaded a stylesheet that made it look pretty:

The problem is that the text belonging to the Dygraph is visible through the date picker.

Answer 1

Edit or override the z-index property on the CSS.

The graph title z-index should be smaller than any of the date picker.
