Contents

Contentコンポーネントは、スクロール可能領域を制御するいくつかの便利なメソッドを備えた、 使いやすいコンテンツ領域を提供します。 1つのビューに表示できるコンテンツは1つだけです。

Contentは、他の多くのIonicコンポーネントと同様に、 CSS Utilities で提供されるグローバルスタイルを使用するか、CSSおよび使用可能な CSS Custom Properties を使用して個別にスタイル設定することによって、paddingmargin などを変更するようにカスタマイズできます。

Fixed Content

In order to place elements outside of the scrollable area, slot="fixed" can be added to the element. This will absolutely position the element placing it in the top left. In order to place the element in a different position, style it using top, right, bottom, and left.
