They were a badge of technical prowess. They screamed complexity. They let everyone know how dynamic the site had become.</p> <p><img src="Screenshot%202019-12-02%20at%2020.24.51.png" alt="screenshot showing a page foorter displaying the number of database queries and server time taken to render the page"></p> <p>Performance wasn&rsquo;t given much of a thought and as long as your pages rendered reasonably quickly, things were good. Most never noticed these footers. If they did, there was little they could do with the information. It wasn&rsquo;t long before these vanished from site footers, into HTML comments at the end of the page. Web development has moved on and I struggled to find an example of this practice used today.</p>
