Looking for a solution to streamline the process of updating multiple web pages with identical header and footer content. Currently have 5-10 pages with the same information, making it time-consuming to manually update each one when changes are needed. Is there a way to embed an HTML file containing this repeated code block to simplify updates? For example, I need to change the copyright year in the footer from 2015 to 2016 across all pages without having to do it individually. Any suggestions on how to achieve this efficiently?
