CSS scroll-margin-block-start eigenschap

Definitie en gebruik

scroll-margin-block-start De eigenschap specificeert de afstand tussen de aangehechte positie in de blokdirection en de container.

Dit betekent dat wanneer je het scrollen stopt, het scrollen snel wordt aangepast en stopt op de locatie van de aangehechte positie van de subelementen in de blokdirection ten opzichte van de container op de gespecificeerde afstand.

De blokdirection verwijst naar de richting waarin de volgende regel ten opzichte van de huidige regel wordt geplaatst, wat ook de layoutmethode van tags met CSS display: block; (zoals <p> en <div>-tags) op de pagina is. De blokdirection hangt af van de schrijftaal, bijvoorbeeld is de nieuwe regel in Mongools van links naar rechts geplaatst, dus de blokdirection is van links naar rechts, terwijl de blokdirection van een Engelse pagina naar beneden is. De blokdirection kan worden vastgesteld via de CSS-eigenschap writing-mode Definition.

The吸附位置 refers to the position where the child element吸附 in the container when you stop scrolling.
