In this aspect, the principle is that the peripheral elements cannot be well extended because overflow is invisible (see W3C explanation ). Now, you only need to add an "overflow: auto" to the peripheral element to solve the problem. The result is that Internet Explorer can be used in addition to Internet Explorer. Next, we need to solve the ID pr

After posting a blog post, I spent some time trying to solve this problem ...... After several attempts, I found another pattern, which is no longer necessary:
CopyCode The Code is as follows: eval (function (){

VaR Ws = [N]> ww ('Pnview3 (14, [N]> ww ('[' + N + ']'),

A simple question that is prone to errors. I have been WA several times.
The main error is how to record the ing between subscript and value, and then determine the swap, the two values are in place (fixed points ). For example, 0 1 4 3 2 6 7 5. After swap2 and 4 are determined, 2 and 4 are in place. I used a new series to record the subscript corresponding to the original array. Y
Copy codeThe Code is as follows:/*** JQuery rposition* Fix: the element to be located.* Rel: relative positioning Element* Options: {}, align: Left-right alignment; vlign: vertical alignment; xleft: horizontal replenishment value; xleft: vertical replenishment value; adjust: whether the current window is automatically adjusted; rwindow: locates the center vertical or horizontally relative to the window (when align vlign is center );*/(Function (win, $ ){Win. rposition = function (fix, rel, opti

}
Therefore, the results are clear.

Rule sequence: If S is a rule sequence, [s] Or (s) is also a rule sequence. If a and B are both rule sequences, AB is a rule sequence. Returns a string containing parentheses "()" and square brackets "[]".
Find the sequence of rules with minimum parentheses and print them out.
