What are the gridlines on my Wix site (Old Editor)?
Gridlines appear inside your Editor to help you build your site's layout correctly. Currently your site is fixed at 980px in order to accommodate the largest number of internet users that will be visiting your site. Place all of your site's content inside the Gridlines to ensure its compatibility across different browsers and devices.
The gridlines do not appear on your live site - they are there as a guide that can help you map and design your site better. To remove the gridlines, simply click on the gridlines icon from the top menu.
