FORMATTING TIP: Notice how the frame for Example-1 is not as wide as the frame for Example-2. The reason is because the text in the Example-1 ‘description label’ is wrapped using the ‘wraplength’ attribute (see line ___). Whereas the wrap in the Example-2 ‘description label’ is forced using ‘n’, which is the code for ‘return’. The frame flexes because ____ .
TRY THIS: In line ___, change the wraplength amount and see how the Example-1 frame width changes.
TRY THIS: In line ___, move the move or delete the ‘n’ to see how the Example-2 frame width changes.

Reputable theme developers should give you a quick response with a new theme file. If you’re the theme developer, read this guide on creating child themes, especially the section about making a stylesheet. Look for a new theme: This is most likely the best course of action, considering it’s rare for a quality theme developer to miss one of the most critical parts.
