デザイン：cssで3D ＆回転Design　ソースコードを確認＆コピペできます。

デザインで遊んでみました。このままの形で実際に、使うことが少ないかもしれませんが、ややこしい部分はHTMLと.cssのSource Codeをご覧いただけます。コピペすればそのままの形で利用できますので。チョッとした発想の転換や他に応用で来るかも知れません。順番を追って記載し、一番最後の部分のSourceをご覧いただける様にしています。

疑似球体に近づける

輪っかを疑似球体に近づける為に回転させる為に、複数の輪っかを15度毎に配置して回転を付けました。（Y軸：0～360）

輪っかの反転

輪っかの周りに簡単な飾りをつけて、X軸：0～-360deg、Y軸：０～360degで、反転させています。

_____

15度・75度・135度で交差

概要

輪っか3枚の画像を60度で交差させ反転させて
輪っかの内外周には、飾りを設けRainbow表示をさせています。
