It's most often used on the <html> tag to set the entire page's direction, which is crucial for supporting languages that are written from right to left (RTL), such as Arabic and Hebrew. For example, using <html dir="rtl"> makes the entire page display from right to left, adjusting the layout and text flow accordingly.rem is a best practice for achieving this, as they allow the text to scale uniformly based on the user's browser settings.
