solve the differences between the browser CSS display, but after all, do not conform to the specifications, we usually write CSS is best in accordance with the standard, so that we later maintenance is also a great advantage, really no longer use.the CSS hack to distinguish different browsers:Difference between IE6 and FF:Background:orange;*background:blue;Difference between IE6 and IE7:Background:green!important;background:blue;Difference between IE7 and FF:Background:orange; *background:green

from the remaining number, if the difference is a multiple of 7, The original number can be divisible by 7. If the difference is too big or it is difficult to see whether it is a multiple of 7, we need to continue the process of "tail truncation, doubling, subtraction, and verification" until we can clearly determine whether it is possible. For example, the process of judging whether 133 is a multiple of 7 is as follows: 13-3 × 2 = 7, so 133 is a multiple of 7. For example, the process of judgi
