I like to use the overflow: auto CSS property/value pairing. This will render the parent object the way you'd expect it to appear. If the text within the parent is too wide, scrollbars appear within the object itself. This will keep the structure the way you want it to look and provide the viewer with the ability to scroll over to see more.

Edit: the nice thing about overflow: auto compared to overflow: scroll is that with auto, the scrollbars will only appear when overflowing content exists. With scroll, the scrollbars are always visible.
