專案實戰之玩轉div+css製作自定義形狀
專案需求
要求製作上圖所示的效果，能達到靈活可配的效果。我想初步想法是用div+css來製作。
------------------------------------------------------------------------------------------------------
模型抽象
下面的這個模型是我抽象出來的一個簡單的解決方案。div可以表示一個矩形，然後再加上一個旋轉90度的div就可以組起來達到我們想要的效果了。使用div就可以很方便地相應各種事件，使網站靈活可配。
------------------------------------------------------------------------------------------------------
技術難點
1、如何做到讓div旋轉？
-moz-transform: rotate(90deg);
如果設置的值為正數表示順時針旋轉，如果設定的值為負數，則表示逆時針旋轉
2、如何設定div的層次關係？
z-index

實踐效果
總結思考
1、面對複雜的問題，要學會抽象當前的問題。
2、不將就是發現的原動力。
