html - Internet Explorer 7 strange behaviour for drop down list -

-

created simple html/css drop down navigation using nested unordered lists.

works great firefox, chrome, ie8 in ie7 sub navigation doesn't sit below parent, instead sits below parent right.

for example , html/ css have here http://webfe.omega.studiocoast.com.au/

i'm stumped!

ie gets confused position: absolute inside floats auto layout. set explicit left: 0 on .sub_nav , position: relative on parent (floated) li avoid this.

(is float: left; display:inline-block; intentional, work around other bug or something? doesn't make sense itself.)

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...
