### 実現したいこと

あるdiv要素の中にspan要素とappend(" ")で追加された空白が混在していた場合、空白を消す方法はあるのでしょうか。removeを使ってもできないですし、そもそもデベロッパーツールで挿入されている部分を見ても空白があるのかどうなのか判別できません。progateのエディタでは実際にこうしているかは分かりませんが、デベロッパーツールで見た限りではこれを実現しているように見えます。詳しい方がいらっしゃいましたらご教授の程宜しくお願いします。

ご指摘を受けてコードの一部を記載いたしました。contenteditable属性のついたdiv部分をクリックしていただいて文字を入力すると、空白を入力したときを除いて文字がspanで囲まれるようになっております。私の至らぬ点大変ご迷惑をおかけしました。
