In this program, what makes me feel better is:
VaRR, G, B;
R = dectohex (randomnumber (256)-1 );
G = dectohex (randomnumber (256)-1 );
B = dectohex (randomnumber (256)-1 );
Document. bgcolor = "#" + R + G + B;

1. Reduce the number of HTTP requests: CSS
Just contact the assembly, a lot of details are not very clear, wrote a decimal and hexadecimal conversion between the program (a bit of a setback.) ) as a practiced hand.Post code, hope that the passing of Daniel can give some guidance.Idea: (10->16
Output:
//
Returns: int rslt converted decimal data

Train of thought: hexadecimal the range of decimal digits represented by each character bit is 0 ~255, and the system is 256.
