Write markdown

This function takes a string of markdown as input and returns an Html object. Output the object as the last expression of a cell to render the markdown in your app.


You can interpolate Python values into your markdown strings, for example using f-strings. Html objects and UI elements can be directly interpolated. For example:

text_input = mo.ui.text()
md(f"Enter some text: {text_input}")

For other objects, like plots, use marimo’s as_html method to embed them in markdown:

import matplotlib.pyplot as plt

plt.plot([1, 2])
axis = plt.gca()
md(f"Here's a plot: {mo.as_html(axis)}")


Enclose LaTeX in single ‘$’ signs for inline math, and double ‘$$’ for display math or square brackets for display math. (Use raw strings, prefixed with an “r”, to use single backslashes.) For example:
    The exponential function $f(x) = e^x$ can be represented as

        f(x) = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \ldots.


The exponential function \(f(x) = e^x\) can be represented as

\[f(x) = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \ldots.\]

You can render icons from Iconify with mo.icon.

marimo.icon(icon_name: str, *, size: int | None = None, color: str | None = None, inline: bool = True, flip: Literal['horizontal', 'vertical', 'horizontal,vertical'] | None = None, rotate: Literal['90deg', '180deg', '270deg'] | None = None, style: dict[str, Union[str, int, float, NoneType]] | None = None) Html#

Displays an icon. These icons are referenced by name from the Iconify library.

They are named in the format icon-set:icon-name, e.g. lucide:leaf.

Icons are lazily loaded from a CDN, so they will not be loaded when not connected to the internet.

These can be used in buttons, tabs, and other UI elements.

Examples."# {mo.icon('lucide:leaf')} Leaf")

    label=f"{mo.icon('lucide:rocket')} Submit",


  • icon_name: the name of the icon to display

  • size: the size of the icon in pixels

  • color: the color of the icon

  • inline: whether to display the icon inline or as a block element

  • flip: whether to flip the icon horizontally, vertically, or both

  • rotate: whether to rotate the icon 90, 180, or 270 degrees

  • style: a dictionary of CSS styles to apply to the icon


  • An Html object.
