Zebra striping

Zebra striping is the coloring of every other row of a table to improve readability. Especially in wide tables with numerous columns, it can be difficult for a reader following a row to be confident that their gaze has not strayed to an adjacent row without some means of distinguishing rows at a glance. Although zebra striping has been used for a long time to improve readability, there is relatively little data on how much it helps.

Implementation

In HTML documents, zebra striping can be implemented using the Cascading Style Sheets :nth-child pseudo-selector.
The Bootstrap CSS framework features zebra striping through the .table-striped class.
