visible: The scroll bar is never displayed, and the size of the text area will automatically grow according to the increase in content to display the entire content.
scroll: No matter how much content is in the text area, the scroll bar is always displayed.
hidden: The scroll bar is never displayed, and objects whose content exceeds the level are not displayed.
auto: If the content can be fully displayed in the text area, the scroll bar is not displayed. When the content cannot be fully displayed, the content is truncated, and the scroll bar is added to display
all the content.
Note]: The overflow attribute of style must be used in conjunction with the width attribute to take effect!
