Thingworx CSS Selectors
Hello,
In the few Thingworx Custom CSS tutorials/how-tos that I can find they all mention selectors such as, ".widget-button", ".button-element", "widget-button-text" etc. Clearly these selectors are not extensive enough to cover things such as an advanced grid's rows, or columns for example. Is there some resource out there that lists all of these selectors? How do I select an advanced grid's first column header?
I am well aware that you can copy an element's selector through developer tools on google chrome. This is not good enough as these selector's values may change over time.
