A missing closing ``` causes the rest of the document to render as code, so headings and lists disappear.
Fix: Make sure every opening ``` has a matching closing ``` on its own line.

Markdown is a lightweight markup language with plain-text formatting syntax, widely used for READMEs, documentation, and content-first publishing.
Markdown to HTML is an online converter that transforms Markdown source (CommonMark and GitHub Flavored Markdown) into clean, sanitized HTML you can paste straight into a README, static site, CMS, newsletter, or email template.
It supports headings, lists, tables, task lists, fenced code blocks, blockquotes, inline formatting, and links, and strips unsafe constructs such as inline scripts and `javascript:` URLs so the output is XSS-safe out of the box.

GitHub Flavored Markdown tables require a `| --- | --- |` separator row directly under the headers.
Fix: Add the separator row under the header so the table is recognized and rendered.
Inline `<script>` tags, event handlers, and `javascript:` URLs are removed so the output is XSS-safe.
Fix: Move interactive behavior out of the Markdown source and into the destination template.
Some embedded HTML is preserved, but attributes that look unsafe are dropped during sanitization.
Fix: Use plain Markdown where possible and keep embedded HTML limited to safe structural tags.
Yes. GFM features such as tables, task lists, strikethrough, autolinks, and fenced code blocks are supported alongside standard CommonMark syntax.
No. The converter runs in the browser, so pasted Markdown stays on your device while you work.
Yes. Inline scripts, event handlers, and `javascript:` URLs are stripped so the HTML is safe to paste into blogs, CMS fields, and email templates.
Yes. Include a GFM-style header separator row and the converter will emit a full `<table>` with `<thead>` and `<tbody>` sections.
