Visual hierarchy is the arrangement of elements in a design to guide the viewer's eye and convey importance. By using size, color, contrast, and spacing, designers can create a clear path for the audience to follow. For example, a large, bold title at the top of a webpage immediately draws attention, while smaller text below provides supporting information. This concept is crucial in various fields, including graphic design, web design, and advertising. Effective visual hierarchy helps users quickly understand the message and navigate content, making it easier to engage with the material. Ultimately, it enhances the overall user experience.
