After examining the CSS code, I am still unable to locate the specific property that is being applied to the main element.
I am currently customizing the select2 library to suit my needs. However, I am stuck in the CSS as I cannot determine which property controls the border display on the active or focused element.
I have searched for any :active
selector in the CSS file and even checked the JavaScript file, but I did not find anything there. Even while debugging, no CSS styling seems to be applied to that particular element.
