Scroll is suitable for long content that needed to be placed inside small screen area. Useful to make a region within the page independently scrollable.
Scroll indicator, the shadow, provides an extra visual cue that content exists below or above the fold.
Maximum width and height may be set explicitly via props, as in example above. Size also may be controlled by external container.
If content goes further rigth side of the Scroll, it may reflect such behavior.
User is capable to scroll content even without visible scrollbar.
