        Parameters
        ----------
        body : str
            The string to display.

        help : str or None
            A tooltip that gets displayed next to the text. 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``.

        width : "content", "stretch", or int
            The width of the text element. This can be one of the following:

            - ``"content"`` (default): The width of the element matches the
              width of its content, but doesn't exceed the width of the parent
              container.
            - ``"stretch"``: The width of the element matches the width of the
              parent container.
            - An integer specifying the width in pixels: The element has a
              fixed width. If the specified width is greater than the width of
              the parent container, the width of the element matches the width
              of the parent container.

        Example
        -------
