 Here are some examples of what a post with images might look like. If you want to display two or three images next to each other responsively use `figure` with the appropriate `class`. Each instance of `figure` is auto-numbered and displayed in the caption.

 Syntax highlighting is a feature that displays source code, in different colors and fonts according to the category of terms. This feature facilitates writing in a structured language such as a programming language or a markup language as both structures and syntax errors are visually distinct. Highlighting does not affect the meaning of the text itself; it is intended only for human readers.[^1]
