A slider serves as a dynamic gallery that displays a slideshow of several different photos or graphics.
Sliders usually scroll through images automatically, but they can also be manually paused or perused by users. Often, users can click on a hyper-linked image as it appears in the slider to be directed to a page devoted to that particular subject or promotional offer.Sliders serve not only as a visual focal point, but also as a table of contents. For example, a slider on a news website might feature the current top headlines.
On a commercial website, web developers might use a slider to lure customers with various promotional offers. A slider on a photographer’s blog might include photographs representative of their best work.
