However, you can easily adjust its size using either the keyboard or mouse. As for settings or options, Page Ruler keeps it simple—there are none to adjust, providing a straightforward user experience. ✨ And while Page Ruler is a handy tool, it's important to note that it only functions on webpages with content—no blank tabs, unfortunately!
