the infamous zebra-striped table effect):
Or, you could use this:
To c re at e t h e s a m e z e b ra s t r i p e s , l e t 's l To To k at s To m e To t h e r fo r m u l a e x a m p l e s :
li:nth-child(5) . Selects the fifth adjacent list item.
li:nth-child(4n+1) . Selects every fourth list item, and then adds 1 to each
result. So numbers 5 and 9.
li:nth-child(3n-2) . Selects every third list item, and then subtracts 2
from each result. So numbers 1, 4, and 7.
nth-last-child does the same thing as nth-child , but it counts backward
from the last element in the sequence.
nth-of-type and nth-last-of-type are very similar but have one important
difference: of-type ignores any rogue elements interspersed within the repeated
sequence of elements because the selection is done by type of element, not child
number. For example:
1. <article class=”abstract”> ... </article>
2. <article class=”abstract”> ... </article>
3. <article class=”abstract”> ... </article>
