It absolutely does show changes for all file types. Check your preferences to see that all folders you want to watch for file changes are included.
A better option than Live Reload, IMO, is Prepros. It's a powerful browser previewer, among other things, letting you preview across multiple browsers on multiple devices, with navigation and scrolling syncing.
You can have Chrome, Firefox, Edge and Opera open across multiple screens, have browsers open on multiple devices, like an iPhone, a Samsung phone and an iPad in my case, and if you scroll on one of the phones or navigate, all the other browsers do the same thing simultaneously. It's pretty neat.
