overflow

问题 What am I expecting is a page that is not overflowing since there is no content and hence have no need to scroll. But what I am getting is a page that is empty but it still scrolls, and isn't just a cosmetic issue of the scroll bars appearing on the touch event. It actually offsets the background in the view port. I've been trying everything that Google has thrown at me to make sure the width and height of the body block is the size of the viewport and no greater. I've also tried over-flow:

问题 i have a problem with scale transforme effect and overflow on Safari. When i used this effect on a div content, the overflow not work on a rounded container. here my code: .container{ width:100px; height:100px; border-radius: 50%; background:none; z-index:100; box-shadow: inset 0 0 0 6px rgba(255,255,255,0.6), 0 1px 2px rgba(0,0,0,0.1); overflow:hidden; -webkit-transition:all .9s ease-in-out; // Chrome Safari -moz-transition:all.9s ease-in-out; // Mozilla -o-transition:all.9s ease-in-out; //

问题 I have a parent div that contains an absolute positioned child div. The child div is positioned outside the initial boundaries of parent div. It was rendering normally without any problems. I added an overflow-y: scroll; to the parent div, and now the child element is hidden despite adding overflow-x: visible; . CSS #parent{ position: relative; overflow-y: scroll; overflow-x: visible; } #child{ position: absolute; left: -50px; } Also a Fidle 回答1: Well found this on stackoverflow, but you aren

问题 can I trust that the C compiler does modulo 2^n each time I access a bit field? Or is there any compiler/optimisation where a code like the one below would not print out Overflow? struct { uint8_t foo:2; } G; G.foo = 3; G.foo++; if(G.foo == 0) { printf("Overflow\n"); } Thanks in Advance, Florian 回答1: Yes, you can trust the C compiler to do the right thing here, as long as the bit field is declared with an unsigned type, which you have with uint8_t . From the C99 standard §6.2.6.1/3: Values

问题 In C, unsigned int size = 1024*1024*1024*2; which results a warning "integer overflow in expression..." While unsigned int size = 2147483648; results no warning? Is the right value of the first expression is default as int? Where does it mention in C99 spec? 回答1: When using a decimal constant without any suffixes the type of the decimal constant is the first that can be represented, in order (the current C standard, 6.4.4 Constants p5): int long int long long int The type of the first
