Favicon stands for favorite icon but more relevant than its name is the purpose of the
favicon
to provide enhancement to your branding of your site/application as the site is bookmarked
and
referenced. The favicon image will appear with the domain in the address bar, tabs,
bookmarks,
search results, and other areas depending upon the browser.
You may have encountered a reference to a 404 NOT FOUND favicon error in the browser's
DevTools console when other not found errors are present on your https enabled GitHub Pages site.
Prepare
The Favicon ("Fav-icon") is a small image file that can be 16px X 16px, however Google
development
recommends multiples of 48px square.
Most web image file formats are supported, however, the preferred .ico
format is what we will use in the course.
