How do I change the background color of highlight effect?

Hi Guys

When I select a field to put data in, the whole field is highlighted that yellow colour, I no longer can see the font as I've set it as WHITE

I want to use this color scheme, but i don't know how to change the background color from yellow to something else? 

Hello,

You may change the background color of highlight effect using custom css codes:

.form-line-active {

  background-color: your color !important;

}

The code must be injected according to the next guide: How-to-Inject-Custom-CSS-Codes

Let us know if you need more help.

Thanks
