Q: favicon.ico A: A `favicon.ico` is a small icon associated with a particular website or web page. It is displayed in various places by web browsers, such as in the address bar, tabs, or bookmarks. The "ico" in `favicon.ico` refers to the file format originally used for these icons, though modern browsers also support other formats like PNG or SVG. To implement a favicon for your website, you typically need to: 1. Create an icon file (usually 16x16 or 32x32 pixels). 2. Save it as an `favicon.ico` or another supported format (e.g., `favicon.png`). 3. Place the file in the root directory of your website or specify its path in the HTML `` section using a `` tag, like this: ```html ``` Including a favicon enhances the user experience by helping users easily identify and navigate to your website from their tabs or bookmarks.
