Front-End Web Development: The Big Nerd Ranch Guide

For the More Curious: The favicon.ico

Have you ever noticed the little icon that appears at the left end of your browser’s address bar when you visit most websites? Sometimes they also appear in your browser tab, as in Figure 2.19.

That is the favicon.ico image file. Many sites have one, and browsers request one by default. Because Ottergram does not have one, you may see an error like the one in Figure 2.20 in the DevTools.
