how is this going to resolve the design interface if cant load the css and js?
For WRIO Internet browser, browser plugin or mobile app it's like a default google chrome theme that can change on another. Or like you have the same facebook UI for all pages, but our variant is global and without vendor lockup and you'll be able to choose or develop you own theme.
Yes, you have to download theme (markup+ css + js) by using WRIO OS node (e.x. load
https://wrioos.com itself), but after that you use browser cache to render any other hubs:
https://webrunes.com,
https://aa.wr.io or created by you
https://core.wrioos.com/create (sorry for any issues, still in dev). Or you can edit
https://github.com/AlexeyAnshakov/aa.wr.io-WRIO-Hub in any text editor. just upload on any static server and enjoy your own hub.
given that im doing web-based projects? will this browser still suits for the web-based developer?
Yes. But you will have additional features for a web 3.0 hubs.
