tin aid forestall the component from being obscured by mounted parts. These choices supply finer power complete the alignment inside the viewport, permitting you to assumption the component much exactly.

Acquire accurate y
coordinate and usage framework.scrollTo({apical: y, behaviour: 'creaseless'})
const id = 'profilePhoto'; const yOffset = -10; const component = papers.getElementById(id); const y = component.getBoundingClientRect().apical + framework.scrollY + yOffset; framework.scrollTo({apical: y, behaviour: 'creaseless'});
