Aria-label: Normally, the input component of the form form has a corresponding label, and when the input component gets the focus, the screen reader reads the text in the corresponding label. However, if you do not set the label for the input box, when it has the focus, the screen reader reads out the value of the Aria-label property, and Aria-label does not visually render the effect. Aria-labelledby: When the desired label text is already present in other elements, you can use Aria-labelledby and set its value to the ID of the element being read note: If an element is Aria-labelledby and Aria-label at the same time, Will first read the contents of the Aria-labelledby.
