WP_Customize_Custom_CSS_Setting::is_possible_content_error( string $css )

Find “content:” within a string.

Description Description

Imbalanced/Unclosed validation errors may be caused when a character is used in a "content:" declaration.

This function is used to detect if this is a possible cause of the validation error, so that if it is, a notification may be added to the Validation Errors.

Example: .element::before { content: "(\""; } .element::after { content: "\")"; }

Using ! empty() because strpos() may return non-boolean values that evaluate to false. This would be problematic when using a strict "false === strpos()" comparison.
