Paste markdown containing CSS and the preview renders the document with the stylesheet code highlighted; when you are ready, Share produces a link to the rendered page.
CSS ends up in markdown when a visual decision needs explaining. A design system team publishes its color and spacing tokens with a note on when to use each. A developer documents why a flexbox layout collapsed on narrow screens and which rule fixed it. A style guide lists the focus styles every interactive element must keep. The readers are often designers and developers together, and they want to see selectors and values without opening the codebase.
In the preview, selectors, properties, values, units, at-rules such as @media, and comments are colored, which makes a long block of custom properties or a cascade of media queries easier to scan. Markdown tables are handy for listing tokens with their values and purpose next to the code.
The CSS in your document is not applied to anything: it is displayed as code and does not change how the page looks. There is no linter, so typos in property names are not flagged. Only the css tag is highlighted; SCSS or Less blocks render as plain monospaced text. The shared link opens read-only for anyone who has it, needs no account, and stops working once the document expires 15 days after creation.
How to view CSS in markdown
- Paste your markdown into the editor above, or edit the example.
- Wrap CSS code in a fenced block that starts with ```css.
- The preview shows the rendered document with the code highlighted (side by side on desktop; switch to Preview on a phone).
- Select Share to get a read-only link that anyone can open without an account.
Frequently asked questions
Does the CSS in my document change how the page looks?
No. It is shown as highlighted code only. The document’s appearance comes from sharemd.net’s own styles and the light or dark theme.
Are SCSS and Less highlighted?
No. Only ```css is highlighted. Blocks tagged ```scss or ```less display as uncolored monospaced code; plain CSS inside them still reads fine.
