Hadron supports a simple coming soon or offline style page with a time counter. It has been specifically styled to match the theme. This feature can be enabled in Admin Dashboard → Hadron Theme → Gizmos → Coming Soon Page. You can customize this page by editing the comingsoon.php file inside the theme folder. Please visit Hadron tutorials for more information.
This gizmo hides your WordPress site behind the Coming Soon page with its Countdown timer. You can still access the frontend of the site by logging in as an administrator below. You can customize this message in the Hadron theme language file.
