つまり、HTMLがたくさんあるとすると、特定の要素の最大の高さは固定数であると言いたいと思います。要素を複数の要素にどのように分割しますか?それぞれの要素の高さは、要素の制限ごとに必要な高さよりも高くありませんか?これは明らかにウィンドウの幅に依存するため、要素の高さが目的の高さを超えるように十分に狭いウィンドウがあると想定します。

<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
