What is a favicon? Here's how Wikipedia describes it:
"A favicon /ˈfæv.ɪˌkɒn/ (short for favorite icon), also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons, associated with a particular website or web page."
In other words, it's that little image/icon to the left of your web browser tabs. It helps to identify your site and other sites, especially when you have several tabs open at once.
When you create your new Onescreener page, you can also upload an image to use as your favicon. Here's how:
Setting your favicon
After you've added your background image, your main content and your links, it's now time to publish your page. Click the button at the bottom of your screen.
Onescreener automatically assigns you a starter subdomain for your site. However, in order to add a personal favicon to your site's tab, you must assign your own domain name. Click on the Choose your own domain button.
If you do not already have your own domain name, enter your choice in the field and the system will search for its availability. You will then be directed to upgrade to the Onescreener PREMIUM plan and register your domain.
If you already have your domain name (hosted on another server), click on the link at the bottom of the page, Connect your existing domain, and upgrade to the PREMIUM plan.
When you've upgraded your Onescreener plan and registered your domain, you'll be notified via a pop-up window.
Upon closing the window, you'll be presented with the option to add your favicon.
Upload your favicon image. After you've done this, you must make sure that your new Onescreener site is PUBLISHED (click Go back), and then you should see the favicon on the browser tab when you go to your site's address.
