The Rapidix Markdown Preview uses a client-side Markdown parser to convert Markdown syntax into HTML in real-time. As you type in the editor pane, the tool processes the input through a parsing pipeline that handles all standard Markdown elements: headings (# to ######), emphasis (*bold*, _italic_), lists (ordered and unordered), code blocks (inline and fenced), links, images, tables, blockquotes, and horizontal rules. The parsed HTML is rendered in a preview pane with proper styling applied through CSS classes. The tool uses a split-pane layout with the editor on the left and the live preview on the right, updating instantly with each keystroke. Word, character, and line counts are computed in real-time from the raw Markdown input. The "Copy HTML" button copies the rendered HTML output, while "Copy Markdown" copies the raw source text. Both operations use the Clipboard API for reliable cross-browser copying. All processing happens in the browser's main thread with zero network dependency.

1. Type or paste your Markdown text in the editor pane on the left. 2. The rendered preview appears instantly on the right side. 3. Use the word, character, and line counters at the top for reference. 4. Click "Copy Markdown" to copy the raw Markdown source. 5. Click "Copy HTML" to copy the rendered HTML output. Supported syntax includes: headers (# H1 through ###### H6), bold (**text**), italic (*text*), strikethrough (~~text~~), ordered and unordered lists, code blocks (inline `code` and fenced ```blocks```), links [text](url), images , tables, blockquotes (> text), and horizontal rules (---). Tip: Use this tool to preview README.md files before committing to GitHub, or to draft blog posts and documentation with instant visual feedback.

Use semantic heading levels: Start with # for the title, ## for main sections, ### for subsections. Never skip heading levels (e.g., jumping from # to ###). Keep line lengths manageable: Break long paragraphs into multiple lines. Most Markdown renderers treat single line breaks as spaces, so you can format your source for readability without affecting output. Use fenced code blocks with language specifiers: ```javascript instead of just ``` enables syntax highlighting in most renderers. Prefer reference-style links for repeated URLs: [text][ref] with [ref]: url at the bottom keeps your source cleaner. Use tables for structured data: Markdown tables with | separators are much more readable than trying to format data as plain text. Preview before publishing: Always check your Markdown renders correctly — especially tables, nested lists, and code blocks — before committing to version control or publishing to a CMS.
