If you're building websites using frameworks such as React.js, Vue.js, Next.js, or any other, chances are that they are using their logo as favicon. Having your own favicon is important for users to quickly identify the website associated with each tab when having too many tabs open at once. Customising a favicon can be done in a single line of code by pasting a specific link tag inside the <head> tag in your main HTML file. The code allows you to change the image type if needed, and favicons can also be emojis, such as 🦄 or 🎉. Depending on the tool used to build websites, packages may need to be installed for proper functionality. A favicon generator tool is also available to generate tags automatically in light/dark mode and search engine results.
