In Drupal, blocks are like little puzzle pieces. They’re self-contained pieces of content that can be put in different areas on your website’s theme. So if the header and footer are regions on your website, then consider blocks as the content in them. No matter where you place them, they never lose their shape or functionality. You can fill blocks with all sorts of things like text, images, menus, or forms — perfect for those who want to spice up their website!
