javascript - inline and inline-block difference in "responsive web design with html5 and css3" -


i came across question when reading "responsive web design html5 , css3" chapter3 fluid layouts. author trying change fixed pixel size percent-based fluid size. below html , css code.

html:

<div id="wrapper"> <div id="navigation">   <ul>     <li><a href="#">something</a></li>     <li><a href="#">some other thing</a></li>   </ul> </div>

css:

#navigation ul li{display:inline-block;} #navigation ul li {margin-right:25px;}

given outermost #wrapper of 940px width. author showed naively change margin-right 25px 2.66%(25/940) doesn't work because intermediate parent of <a> <li>, wasn't given specific width.

besides author's suggested solution, author provided solution, change "display:inline-block" "display:inline".

while can understand difference between inline , inline-block extent, these 2 stackoverflow passages(1,2), don't know how works in case.

i guess inline stuff cannot stick close each other, inline-block can. right?

i'm grateful advice. thanks!

the definition percentage margins says

the percentage calculated respect width of generated box's containing block.

the generated box of a element, , containing block nearest block container ancestor.

elements inline-block block containers, when li element inline-block, a element's containing block, , margin percentage of width of li element.

furthermore, shrink-to-fit nature of inline-block elements, creates circular dependency. margin depends on width of li element, , width of li element depends on margin of a element. in such cases, normal margins adjusted resolve such situations, in case setting them 0.

elements inline not block containers, when li element inline, ul element a element's containing block, , margin percentage of width of ul element, same width of #wrapper element.

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.
