Using the "even" and "odd" keywords in CSS selectors
This matches the odd childen of TR (table rows), presumably TDs (table cell data), for “zebra-row” styling of alternating elements.
/* select the odd children of TR */
tr:nth-child(odd) {
...
}
/* guess lol */
tr:nth-child(even) {
...
}Notably, because of the CSS cascade, you may not often need even and odd, because you can just apply one style to all rows, and then override just the even rows with nth-child(even), giving an even / odd result. ¯\_(ツ)_/¯
