等邊三角形
蒜頭君手上有一些小木棍，它們長短不一，蒜頭君想用這些木棍拼出乙個等邊三角形，並且每根木棍都要用到。例如，蒜頭君手上有長度為1,2,3,3的4根木棍，他可以讓長度為1，2的木棍組成一條邊，另外2跟分別組成2條邊，拼成乙個邊長為3的等邊三角形。蒜頭君希望你提前告訴他能不能拼出來，免得白費功夫。輸入格式 ...

CSS做等邊三角形
這裡我列舉的兩種方法 一種用邊框也就是border實現 比較簡單 另一種是用五個div旋轉溢位隱藏實現 在我們平常使用邊框的時候往往是乙個很窄的邊框，所以在視覺效果上邊框看似為直線，事實呢？給乙個小的盒子加乙個很寬的邊框，如下 可以明顯的看出其實並不是像想的那樣邊框是直線或者矩形。其實它是體型滴 下...
