I'm trying to set Fullscreen mode to Off and Load stylesheet:
body{
min-width: 500px !important;
}
I expect to be like a html page, where the WindowInnerWidth minimal, then can't drag the browser window. But when i preview I don't know why that doesn't work.
UPDATE: I think I've solved it.
This doesn't work on Preview Pop Windows.
But I preview through the browser tab page and this can works.
