Display White Theme on First Load Without Delay

Hello @frsarker

I hope you’re doing well.

By default, our website theme was set to black. We’ve recently updated it to load in white mode instead. While the theme does change successfully, there’s a noticeable delay during the initial page load where the black theme appears briefly before switching to white.

This flash of the black theme on first load looks unpolished and negatively affects the user experience from a UI/UX perspective. Ideally, I want the website to display the white theme immediately—without showing the black background at all during the initial load.

Could you please help me resolve this issue so the white theme loads instantly from the very first visit?

Looking forward to your support.
