autofocus global attribute is a Boolean attribute indicating that an element should be focused on page load, or when the
<dialog> that it is part of is displayed.
<input name="q" autofocus />
No more than one element in the document or dialog may have the autofocus attribute. If applied to multiple elements the first one will receive focus.
autofocus attribute applies to all elements, not just form controls. For example, it might be used on a contenteditable area.
Automatically focusing a form control can confuse visually-impaired people using screen-reading technology and people with cognitive impairments. When
autofocus is assigned, screen-readers "teleport" their user to the form control without warning them beforehand.
Use careful consideration for accessibility when applying the
autofocus attribute. Automatically focusing on a control can cause the page to scroll on load. The focus can also cause dynamic keyboards to display on some touch devices. While a screen reader will announce the label of the form control receiving focus, the screen reader will not announce anything before the label, and the sighted user on a small device will equally miss the context created by the preceding content.
