php - How match ID number with CSS regexp -


i'm customising wordpress theme , stuck following css issue. have list of elements follows:

li.block1, li.block2, li.block3, li.block4 {  top: 0; } li.block5, li.block6, li.block7, li.block8 {  top: 150px; } li.block9, li.block10, li.block11, li.block12 {  top: 300px; }

i'm generating code using php , wish use regexp style these elements. i'd achieve following:

- li.block[1-4] {style 1} - li.block[5-9] {style 2} - li.block[10-14] {style 3} - , on...

as i'm generating li.block[number] dynamically based on user input, run few hundreds of elements, believe using regexp right way go.

i've tried following:

  • tried use $ match last element, i'd on how match on range of values
  • tried using last-child attribute match, it's dynamic, can't fix last-child in advance
  • tried use in-range match range, couldn't figure out how check whether number in range
  • and, several other dom matching criteria using css

i think css match condition i'm using erroneous, i'd request experts in forum show me how use $ , range:

how use regexp based on: li.block[number,i, in range a-b] {apply style number, i}?

i'm open other ideas me keep theme dynamic.

thanks in advance, mithun sridharan

css don't know regexp, can use ~:

li {top: 0;} li.block4 ~ li {top: 150px;} li.block8 ~ li {top: 300px;}

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
