+## Description
+
+The *scroll box* pattern adds some CSS classes to the element depending on it's scrolling position.
+
+The element where it is invoked upon has to be scrollable.
+Therefore the eleme must have set the ``overflow`` or ``overflowY`` CSS property set to ``auto`` or ``scroll``.
+Ho(horizontal scrolling is not yet supported.
+
+The classes are:
+
+- ``scroll-up``: when scrolling upwards,
+- ``scroll-down``: when scrolling downwards,
+- ``scroll-position-top``: when the scrolling container is scrolled to the top,
+- ``scroll-position-bottom``: when the scrolling container is scrolled to the bottom.
+
