Final answer:
Smart text offers annotation, readability options, and PDF conversion functionalities.
Step-by-step explanation:
Smart text is a feature that offers more than just a text template. It includes functionalities such as annotation using a sticky note, Beeline for adaptive needs, and the ability to convert text into a PDF. The annotation feature, called Hypothesis, allows you to make notes directly on the textbook while using the Libretexts website. Beeline helps students with dyslexia, dyspraxia, and dyscalculia by providing readability options. Additionally, Smart text allows you to convert any part of the textbook into a PDF for offline reading.
