Overwrite css

[osquiabro]

Bruce the overwrite css setting don't work in version 12.18, in previous version my css without space the class is overwrite with my css, in version 12 always append all class

your picture is not enough to show context, but It's very possible that some css is added "by default".
You would need to post an example so I can see more.

Ideally you would just override in your css what you need to override.

Cheers

Bruce, in version 12 the checkmark Use jQuery styled button don't exist

[Bruce]

correct, all buttons are styled buttons.
So the setting is "always on".
