デザイン：3D Rainbow Sphere

HTMLとcssだけで作る虹色に変化する3Dデザイン

Thank you for reading this post, don't forget to subscribe!

HTMLの基本形はとても簡単なものです。そこからCSSでclassに様々な設定をして３D表示を完成させます。ここではステップを追う事。進捗が見えるようにHTMLとcssの進捗(進化)をcode化表示してあなたのサイトに参考にできるよう、Sourceコードのコピペもできるようにしています。

疑似3D表示

<div class=’ring03‘></div>
<!–図形ベース兄弟要素を01から36個にする（35個追加） –>　
:nth-child() ：擬似クラスで、兄弟要素のグループの中での位置を01～36を選択しY軸の角度を5度刻みの0度から175度までの角度を付け疑似３D表示する（この時点では回転していない状態）。
.sphere03 .ring03:nth-child(01){transform:rotateY(000deg);}
.sphere03 .ring03:nth-child(02){transform:rotateY(005deg);}
｜｜｜
.sphere03 .ring03:nth-child(36){transform:rotateY(175deg);}
0度から175度までの円の360度回転表示で擬似的な球の表示となる
