How it works:

• The plugin automatically adds a character counter below every ACF WYSIWYG field.
• The counter updates live as you type, whether you are in Visual or Text mode.
• HTML tags are ignored in the count, so only the text that will be visible on the front-end is counted.
• If you exceed the limit, the counter turns red and saving is prevented until you reduce the character count.
• Works with dynamic fields, repeaters, flexible content, and ACF Extended.
