html - Bootstrap/CSS: Clearfix affects even/odd index -


i'm using clearfix prevent bootstrap grid breaking when use columns of different heights.

however, once clearfix div added document, columns appear after in source behave if have different even/odd index do.

i have created relevant demo. can see, removing clearfix div, makes colors of divs change if index has changed.

do know may causing , can correct it?

if @ nth-of-type definition specifies

the :nth-last-of-type(an+b) pseudo-class notation represents element has an+b-1 siblings same expanded element name after in document tree, 0 or positive integer value of n, , has parent element. see :nth-child() pseudo-class syntax of argument.

the key thing here states:

the same expanded element name

so taking quite literally, css selector targets specific element , odd , matched on specific element name , not elements matched using specific selector.

this why replacing divwith span work never matched different element.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
