私は、あなたのニーズにこれを調整することができます確信してます。https：/ /codepen.io/achudars/pen/Cpast –
@Rachel Gallenありがとうございますが、実際はありません。私はJQueryについて考えていないし、私はそれが好きではない。私は純粋なjsを最初に学びたいと思っています。私は得ることができる空間を必要とするので、私は私のコードにjqueryを入れる余裕がない、私はそれが3つの関数のためにそれを使用すると、それは無駄になるかもしれないかもしれない。 –
さて、ちょうど私が出会った何か。私は純粋なjsをほぼ完了しましたが、その後私のラップトップを離れる必要がありました。今道路に乗って、遅くまで戻ってくることはありません。 （7/8時間）あなたが別の答えを持っていないなら、後で投稿します。 –
