Side borders are decorative elements that run along the left and right edges of a page or document. They can enhance the visual appeal of printed materials, such as books, reports, or invitations, by framing the content and drawing attention to it. Side borders can vary in style, color, and thickness, allowing for customization based on the theme or purpose of the document. In graphic design, side borders are often used to create a cohesive look and feel. They can be simple lines or intricate patterns, and they help to guide the reader's eye. Many software programs, like Adobe InDesign or Microsoft Word, offer tools to easily add and modify side borders.
