css selectors - CSS select: how to count and select child of a specific class only? -


given html items @ same level such:

<div class="h2">title: colors</div>  <div class="pair">hello world (1)</div>  <div class="pair">hello world (2)</div>  <div class="pair">hello world (3)</div>  <div class="pair">hello world (4)</div>  <div class="pair">hello world (5)</div>  <div class="pair">hello world (6)</div>  <div class="h2">title: units</div>  <div class="pair">hello world (1)</div>  <div class="pair">hello world (2)</div>  <div class="pair">hello world (3)</div>  <div class="pair">hello world (4)</div>  <div class="pair">hello world (5)</div>  <div class="pair">hello world (6)</div>

how select n+3 , n+4 .pair elements starting previous .h2 element ?

so 1&2 white, 3&4 pink, 5&6 white, etc.

i tried .pair:nth-child(4n+3), .pair:nth-child(4n+4) { background: #ffaaaa; } count child of body .h2 child , break balance.

edit: no pure css selector found select adjacent items following pattern such .class (n+3). alternatively, an infinite series of css selectors such div + .class + .class + .class ...; wrapping in div :nth-child(n+3) or :nth-of-type(n+3); or js needed. know other hack ? sharing welcome !

out of boredom , curiosity i've written function this. in case stuck html , have extended rows this, plugin useful you.

copy function jsfiddle , use so:

var pair1 = findcousin('h2', 'pair', '4n+2'); var pair2 = findcousin('h2', 'pair', '4n+3'); var s = pair1.add(pair2);

you can change h2 , pair 2 different class names, or use different patterns long has #n in it, , optionally +# css nth child selector. adding false fourth argument...

findcousin('list-title', 'list-item', '3n', false);

...will select after first list-title in given pattern, rather after each list-item.... if makes sense.

i believe sh0ber has written more practical solution, has been fun make , might share.
