|

|
||||
Parameters
|
||||
----------
|
||||
body : any
|
||||
The text to display as GitHub-flavored Markdown. Syntax
|
||||
information can be found at: https://github.github.com/gfm.
|
||||
If anything other than a string is passed, it will be converted
|
||||
into a string behind the scenes using ``str(body)``.
|
||||
|
||||
This also supports:
|
||||
|
||||
- Emoji shortcodes, such as ``:+1:`` and ``:sunglasses:``.
|
||||
For a list of all supported codes,
|
||||
see https://share.streamlit.io/streamlit/emoji-shortcodes.
|
||||
|
||||
- Streamlit logo shortcode. Use ``:streamlit:`` to add a little
|
||||
Streamlit flair to your text.
|
||||
|
||||
- A limited set of typographical symbols. ``"<- -> <-> -- >= <= ~="``
|
||||
becomes "← → ↔ — ≥ ≤ ≈" when parsed as Markdown.
|
||||
|
||||
- Google Material Symbols (rounded style), using the syntax
|
||||
``:material/icon_name:``, where "icon_name" is the name of the
|
||||
icon in snake case. For a complete list of icons, see Google's
|
||||
`Material Symbols <https://fonts.google.com/icons?icon.set=Material+Symbols&icon.style=Rounded>`_
|
||||
font library.
|
||||
|
||||
- LaTeX expressions, by wrapping them in "$" or "$$" (the "$$"
|
||||
must be on their own lines). Supported LaTeX functions are listed
|
||||
at https://katex.org/docs/supported.html.
|
||||
|
||||
- Colored text and background colors for text, using the syntax
|
||||
``:color[text to be colored]`` and ``:color-background[text to be colored]``,
|
||||
respectively. ``color`` must be replaced with any of the following
|
||||
supported colors: blue, green, orange, red, violet, gray/grey,
|
||||
rainbow, or primary. For example, you can use
|
||||
``:orange[your text here]`` or ``:blue-background[your text here]``.
|
||||
If you use "primary" for color, Streamlit will use the default
|
||||
primary accent color unless you set the ``theme.primaryColor``
|
||||
configuration option.
|
||||
|
||||
- Colored badges, using the syntax ``:color-badge[text in the badge]``.
|
||||
``color`` must be replaced with any of the following supported
|
||||
colors: blue, green, orange, red, violet, gray/grey, or primary.
|
||||
For example, you can use ``:orange-badge[your text here]`` or
|
||||
``:blue-badge[your text here]``.
|
||||
|
||||
- Small text, using the syntax ``:small[text to show small]``.
|
||||
|
||||
|
||||
unsafe_allow_html : bool
|
||||
Whether to render HTML within ``body``. If this is ``False``
|
||||
(default), any HTML tags found in ``body`` will be escaped and
|
||||
therefore treated as raw text. If this is ``True``, any HTML
|
||||
expressions within ``body`` will be rendered.
|
||||
|
||||
Adding custom HTML to your app impacts safety, styling, and
|
||||
maintainability.
|
||||
|
||||
.. note::
|
||||
If you only want to insert HTML or CSS without Markdown text,
|
||||
we recommend using ``st.html`` instead.
|
||||
|
||||
help : str or None
|
||||
A tooltip that gets displayed next to the Markdown. If this is
|
||||
``None`` (default), no tooltip is displayed.
|
||||
|
||||
The tooltip can optionally contain GitHub-flavored Markdown,
|
||||
including the Markdown directives described in the ``body``
|
||||
parameter of ``st.markdown``.
|
||||
|
||||

You can insert badges everywhere Streamlit supports Markdown by

|

Parameters
|
||||
----------
|
||||
label : str
|
||||
The label to display in the badge. The label can optionally contain
|
||||
GitHub-flavored Markdown of the following types: Bold, Italics,
|
||||
Strikethroughs, Inline Code.
|
||||
|
||||
See the ``body`` parameter of |st.markdown|_ for additional,
|
||||
supported Markdown directives. Because this command escapes square
|
||||
brackets (``[ ]``) in this parameter, any directive requiring
|
||||
square brackets is not supported.

.. _st.markdown: https://docs.streamlit.io/develop/api-reference/text/st.markdown
|
||||
|
||||
icon : str or None
|
||||
An optional emoji or icon to display next to the badge label. If
|
||||
``icon`` is ``None`` (default), no icon is displayed. If ``icon``
|
||||
is a string, the following options are valid:
|
||||
|
||||
- A single-character emoji. For example, you can set ``icon="🚨"``
|
||||
or ``icon="🔥"``. Emoji short codes are not supported.
|
||||
|
||||
- An icon from the Material Symbols library (rounded style) in the
|
||||
format ``":material/icon_name:"`` where "icon_name" is the name
|
||||
of the icon in snake case.
|
||||
|
||||
For example, ``icon=":material/thumb_up:"`` will display the
|
||||
Thumb Up icon. Find additional icons in the `Material Symbols \
|
||||
<https://fonts.google.com/icons?icon.set=Material+Symbols&icon.style=Rounded>`_
|
||||
font library.
|
||||
|
||||
color : str
|
||||
The color to use for the badge. This defaults to ``"blue"``.
|
||||
|
||||
This can be one of the following supported colors: blue, green,
|
||||
orange, red, violet, gray/grey, or primary. If you use
|
||||
``"primary"``, Streamlit will use the default primary accent color
|
||||
unless you set the ``theme.primaryColor`` configuration option.
|
||||
|
||||
Examples
|
||||
--------
|
||||
Create standalone badges with ``st.badge`` (with or without icons). If
|
||||
you want to have multiple, side-by-side badges, you can use the
|
||||
Markdown directive in ``st.markdown``.
|
