Thanks for trying out GWD with events feature.
I am not quite sure how you are trying to change the background color of an element.
Are you using divs or other elements to change its background-color?
If using a div, and if I want to change the background-color by clicking the body for example,
I would do the following
- set div's ID name (yellow)
- Open the events dialog from Events panel(+ sign), set the event: document.body>Mouse:click>CSS:set styles>yellow
- Add background-color:red
- Save
When you preview this on a browser, clicking the body should change the div's background-color to red
Thanks,
