Thanks a lot.

It really helped me. You're an amazing guy.

i now use the puma-dev but i find the app can't load all the js and css file which are included in application.js and application.scss. i find the current app above in the video use the custom css other than bootstrap, hava you ever come across the problem?

Inspect your browser dev tools to see if there are any errors in loading the assets. It could be CORS policy blocking the assets.

the chrome toos show the errors ```ruby Failed to load resource: net::ERR_BLOCKED_BY_CLIENT ```

This is usually something with the browser that is blocking the asset. It could be a browser extension or something.

i find the problem, the chrome plugin adblock blocked it
