I might have posted this before. But I am going to post it again. Because emojis.

Me: 😁 Software lead I have finished coding the thing.
SL: 😀 Cool, good job. That is going to really help out the analysts.
Software Manager: 😐 hey I noticed you have coded a new thing and pushed it to integration.
Me: 😁 Yes.
SM: 😐 Well how do you know when it's done?
Me: 😑 . . . When you run it and it does the thing?
SM: 😐 Did you write test steps?
Me: 😕 Yeah . . . they're in the issue ticket.
SM: 😐 Yeah but how do you know those are right?
Me: 😕 Because I wrote the thing and the test steps?
SM: 😐 did you put any steps in our acceptance test procedure?
Me: 😕 No.
SM: 😐 why not?
Me: 😧 Because the acceptance test procedure tests requirements. There is no requirement for this functionality.
SM: 😑 Then why did you do it?
Me: 🤔 Because it was an internal request from the analysis team. There is no customer impact here.
SM: 😑 I really think we should write a requirement.
SL: 🤔 But what requirement is he going to attach this to?
SM: 😑 We don't have to attach it to a requirement. We can just test it once and remove it.
Me: 😒 SM, you know we never remove anything from the acceptance test procedure.
SM: 🙂 We do sometimes.
SL: 🤔 When was that I have worked here for twenty years and we have never removed a test from that document.
SM: 😑
SL: 😒
SM: 😑
SL: 😒
Me: 🤐
SM: 😧 I really think there should be an acceptance test written.
SL: 😧 Looks like you're writing an acceptance test.
Me: 😒 Alright as long as y'all're payin'. Shit I was just tryin' to save y'all money.

*acceptance test written and sent to peer review*

Peer: 😐 The requirement tested section doesn't have any requirements spelled out.
Me: 😅 No.
Peer: 🤔 Why?
Me: 😓 Because there is no requirement associated with this test.
Peer: 🤔 Then why are we adding an acceptance test?
Me: 😡 WELL AIN'T THAT A GOOD GOD DAMN QUESTION!?

"Quality CSS" is much a fucking misnomer. As someone whose been writing this shit at scale for 15+ years I can tell you all CSS code is garbage. The only thing you should do is make sure you don't have name collisions. Classes/components are self contained. And use variables when possible. DRY makes sense usually, but if you're dogmatic about it you shoot yourself in the foot.
