Final answer:
Headings should be prominent, precede the text they relate to, and stand out on the page while providing structure and helping readers navigate through the content effectively.
Step-by-step explanation:
Headings play a critical role in the structure and presentation of text, serving specific purposes that guide the reader through content. They should stand out on the page to capture attention and introduce the text that follows them, offering a snapshot of what’s to come. It's essential that headings are not placed near the bottom of a page where they could be missed or cause confusion. Instead, they should always precede the relevant text, providing organizational cues and helping to structure the content clearly. Contrary to some beliefs, headings contribute significantly to the message by framing the content and making it more accessible. Additionally, they should be separated from the text that precedes them with appropriate spacing to ensure they are distinct and easily noticeable. This separation helps readers to navigate the text and understand the hierarchy of information. By following these guidelines, headings enhance the reader’s ability to quickly find information and grasp the overall message of the text.
