I’m developing a site for a friends charity(Pro bobo). I am using bedrock with sage 10.

Not sure why but I am getting a flash of unstyled content(FOUC) on every page.

Not sure what code I need to provide or where to begin dubgging. Any ideas would be appreciated.

Are you building assets with dev or production mode? The dev mode (`yarn dev` with default Sage theme) inserts styles via JavaScript to enable hot reloading so you’ll often get FOUC. If you build in production mode (if you aren’t already) (`yarn build` with the default Sage theme) does that fix the issue?

Thanks @thunderdw. That does indeed seem to be the cause.

I notice it when using dev(localhost). Just checked the build and no FOUC it seems. I thought I had already checked this previously, but must have overlooked it.

Much appreciated.
