This document provides an introduction to HTML and covers several basic elements for formatting text in HTML documents, including:
1. Headings (<H1>-<H6>) are used to divide up sections of text and are displayed in decreasing font sizes. Paragraphs (<P>) allow text to automatically wrap to the width of the browser.
2. Breaks (<BR>) insert line breaks, while horizontal rules (<HR>) add horizontal lines across the page.
3. Character formatting elements like <B> for bold, <I> for italics, and <FONT> for changing text size allow styling of individual characters.
