The scroll bar is like a vertical or horizontal bar on the side or bottom of a webpage or document. When you move it up or down (or left and right), it helps you navigate through the content on your screen. Imagine it as a rolled-up paper scroll — by dragging the scroll bar, you reveal different parts of the page.
The vertical scroll bar is usually located on the right side of the screen. It helps you move up and down.
The horizontal scroll bar appears at the bottom of your screen allowing you to move left and right.
You can use your mouse to click and drag the scroll bar, or on a laptop, you might have a touchpad where you can swipe or use two fingers to scroll. The scroll bar is a handy tool for exploring the contents of a webpage or document without having to read everything at once.
