Walkthrough

The css_value_is_valid method in FrmStylesHelper was modified to accept mixed-type input instead of just strings. The method now checks if the input is numeric, returns true if so, returns false for non-string, non-numeric types, and only applies substring checks for strings. The method signature was updated accordingly.

Changes

Cohort / File(s)	Change Summary
CSS Value Validation Logic classes/helpers/FrmStylesHelper.php	Updated css_value_is_valid to accept mixed input, add numeric check, type checks, and update method signature.
