HTML 5 introduced few tags to arrange the page content, which helps to screen readers to understand page structure and content. One of these new tags is Header tag. Footer tag can be used to indicate the footer part of any article/section/document.
A document can have multiple footer tags also. Suppose your web page consists of multiple sections and each section has a footer content, footer tag can be used in each section.
