/*
 * Styles for HTML rendered by sanitise_question_markdown() in

 * (XSS hardening for stored question content, #998), so the rules
 * below must live in a real CSS file loaded by the page templates
 * that inject question_html via innerHTML.
 *
 * Rules are kept in sync with the inline <style> block in
 * markdown_filter() so questions rendered through either path look
 * identical. Selectors are scoped under .markdown-content where
 * possible to avoid leaking into the rest of the page.
