This example demonstrates the common subset of Markdown and reStructuredText markup syntax, using both formats to show how text can be written portably across the two lightweight markup languages. The visualization is rendered as two nearly identical documents side-by-side, with font styling applied to display italics, bold, and monospaced text, along with paragraph and heading structure. It visually compares how the same source content appears in Markdown versus reStructuredText, highlighting the shared formatting conventions (like asterisk-based emphasis) and the differences in extensibility, such as tables and automatic table-of-contents generation. The layout makes it easy to see at a glance how each markup language handles identical input, emphasizing the "common denominator" subset approach for painless conversion between the two.
