Ok so I have create these components
how can I add css into it? WKND tut did it by installing a package. what if I want to do it manually like crx or IDE? how can I achieve this?
the thing is, I can't trace from .html file since there no link found
how does aem do it? connecting this html to gateway or client-libs?
you would need to create a project first, then template/components/clientlibs as mentioned in WKND tutorial.
follow WKND and create your own project from scratch, starting with chapter -1. In chapter-3, you would see how to add clientlibs to your project. You would've to create your own clientlibs either directly in /crx/de or in any IDE, create a package and then upload it to local AEM.
Setup your local workspace with Eclipse or any IDE sync it with AEM server
