    Create an instance like so:

    .. code-block:: python

        widgets = reddit.subreddit("test").widgets

    Data will be lazy-loaded. By default, PRAW will not request progressively loading
    images from Reddit. To enable this, instantiate a :class:`.SubredditWidgets` object
    via :meth:`~.Subreddit.widgets`, then set the attribute ``progressive_images`` to
    ``True`` before performing any action that would result in a network request.

    .. code-block:: python

        widgets = reddit.subreddit("test").widgets
        widgets.progressive_images = True
        for widget in widgets.sidebar:
            # do something

    Access a :class:`.Subreddit`'s widgets with the following attributes:

    .. code-block:: python

        print(widgets.id_card)
        print(widgets.moderators_widget)
        print(widgets.sidebar)
        print(widgets.topbar)

    The attribute :attr:`.id_card` contains the :class:`.Subreddit`'s ID card, which
    displays information like the number of subscribers.

    The attribute :attr:`.moderators_widget` contains the :class:`.Subreddit`'s
    moderators widget, which lists the moderators of the subreddit.

    The attribute :attr:`.sidebar` contains a list of widgets which make up the sidebar
    of the subreddit.

    The attribute :attr:`.topbar` contains a list of widgets which make up the top bar
    of the subreddit.

    To edit a :class:`.Subreddit`'s widgets, use :attr:`~.SubredditWidgets.mod`. For
    example:

    .. code-block:: python

        widgets.mod.add_text_area(
            short_name="My title",
            text="**bold text**",
            styles={"backgroundColor": "#FFFF66", "headerColor": "#3333EE"},
        )

    For more information, see :class:`.SubredditWidgetsModeration`.

    To edit a particular widget, use ``.mod`` on the widget. For example:

    .. code-block:: python

        for widget in widgets.sidebar:
            widget.mod.update(shortName="Exciting new name")

    For more information, see :class:`.WidgetModeration`.

                    "hoverState": {...}
                }

            Both types of buttons have the field ``hoverState``. The field does not have
            to be included (it is optional). If it is included, it can be one of two
            types: ``"text"`` or ``"image"``. A text ``hoverState`` looks like this:

            .. code-block:: text

                {
                    "kind": "text",
                    "text": a string no longer than 30 characters,
                    "color": a 6-digit rgb hex color, e.g., `#AABBCC`,
                    "textColor": a 6-digit rgb hex color, e.g., `#AABBCC`,
                    "fillColor": a 6-digit rgb hex color, e.g., `#AABBCC`
                }

            An image ``hoverState`` looks like this:

            .. code-block:: text

                {
                    "kind": "image",
                    "url": a valid URL of a Reddit-hosted image,
                    "height": an integer,
                    "width": an integer
                }

            .. note::

                The method :meth:`.upload_image` can be used to upload images to Reddit
                for a ``url`` field that holds a Reddit-hosted image.

            .. note::

                An image ``hoverState`` may be paired with a text widget, and a text
                ``hoverState`` may be paired with an image widget.

        :param description: Markdown text to describe the widget.
        :param short_name: A name for the widget, no longer than 30 characters.
