Wix Tutorial - Create a Pre-Loader
When your Wix website loads, it shows a blank white. They say you have only a few seconds to capture someone's attention when they visit your website. A pre-loader is key to retaining website visitors.
Add the code below to the page's head code. To do that go to your Wix Dashboard, then click Settings, and then select Manage Analytics. This opens the Tracking Tools & Analytics window and here you can add a New Tool. Click New Tool and then select </> Custom. Paste the code below in the space for "Paste the code snippet here:" Give the tool a name, for instance, Pre-Loader. Select All Pages, select Head, and then Apply.
You can change the color of the preloader by changing the bold color #000000 with your preferred # color.
