I've been waiting and searching for this for too long, that finally I decide to make it by myself...
Download here: jdcola/evernote-theme-for-joplin: An Evernote-like theme for Joplin
Also as responding to @wanghm365 @Daeraxa @xaholo3700 — Who can help make an Evernote style CSS file? - Support - Joplin Forum , and FYI @whitewall
Will this be bundled as a plug-in in the future?
No plan yet, coz I have zero experience of Joplin plugin development... (I'm an experienced programmer with basic web-dev knowledge, but quite limited practical experiences...)
But I'd like to do it if it's not complicated, being provided some easy-to-follow instructions or template 
Thanks for this update. Just a note of something I discovered...if you are set to dark theme it messes up the style. I just had to switch back to light theme and it looks great!
Thank you. Much appreciated!
amazing
