Hello guys. I have a bit of a problem. My app has header ( navigation bar ) and in its left side i have side bar. The problem is coming with my loading.js since its visible only for the {children} components that are being loaded in the RootLayout, with other words, its visible only in its parent div. However, i want to expand it on the whole screen since it has a background that i was to be visible, currently it only covers the content of the {children}. Please help! Thanks in advance!
