Tips for Better Markdown

Use Fenced Code Blocks

Wrap code in triple backticks with a language identifier (e.g., ```javascript) for automatic syntax highlighting in the preview.

Create Tables with Pipes

Use pipes (|) and hyphens (-) to create tables. Align columns with colons in the separator row: :--- left, :---: center, ---: right.

Task Lists

Create interactive task lists with - [ ] for unchecked and - [x] for checked items. Great for to-do lists and checklists.

Nested Lists

Indent list items with 2-4 spaces to create nested (sub) lists. You can mix ordered and unordered lists at different levels.

Line Breaks

Enable the "Line Breaks" option to convert single newlines to <br> tags. This is useful for poetry or content where line breaks matter.

Escape Special Characters

Use a backslash (\) before special Markdown characters like *, _, #, etc. to display them literally without formatting.
