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 div with span work never matched different element.

i writing notes compare apply() , sweep() , discovered following strange differences. in order generate same result, sweep() needs margin = 1 while apply wants margin = 2. argument specifying matrix uppercase x in apply() lowercase in sweep(). my.matrix <- matrix(seq(1,9,1), nrow=3) row.sums <- rowsums(my.matrix) apply.matrix <- apply(x = my.matrix, margin = 2, fun = function (x) x/row.sums) sweep.matrix <- sweep(x = my.matrix, margin = 1, stats = rowsums(my.matrix), fun="/") apply.matrix - sweep.matrix ##yup same matrix isn't sweep() "apply-type" function? r quirk or have lost mind? note apply , if each call ‘fun’ returns vector of length ‘n’, ‘apply’ returns array of dimension ‘c(n, dim(x)[margin])’ if ‘n > 1’ in example, margin can (and should) set 1 in both cases; returned value apply should transposed. easiest see if original matrix not square: my.matrix <- matrix(seq(1,12,1), nrow=4) apply.matrix <- t(app...
