Angular-cli: Issue: How to resolve warnings in angular-cli?

[bhaidar]

Hello,
This is a question and I need your assistance, please.
I am publishing an application with angular-cli to be able to host it on a web server. However, I am getting warnings after the package is generated.

WARNING in Empty property 'top' at 38528:2. Ignoring.

Can you guide me on where to search to try to find this warning?

See details below:

Maybe a CSS issue? Similar to https://github.com/angular/angular-cli/issues/9784

Hi @msterba
I am importing the Metronic 5 template and I've got hundreds of CSS/JS files. I've been searching for many hours now for this empty property 'top' and I cannot seem to find anything! Is there a log I can generate from angular-cli that would point me to more info about this warning? That's really difficult to find without additional info!

[bhaidar]

I was able to find the problem after a long time searching on that. It was a css rule using this:
top: !important

I changed to
top: 0 !important

Now it works fine!

I have similar issue - the build ends with:

WARNING in Invalid background value at 3171:18. Ignoring.

I went through css and scss files but cannot find the problem. Some more info would be needed to find the source of the problem.

[fhurta]

Why the issue is closed? I upgraded to latest cli 6.1.3 and the behavior has not changed.
Although it is problem in (possibly) external css, if the css reports a warning, it should add some info about the source of the problem

Please reopen, or at least give us a hint...

WARNING in Empty property 'color' at 12401:2. Ignoring.

How des one even begin to diagnose and fix this?

Yea, similar question here: getting multiple animation warnings and I have literally commented out all of my animation code (so I don't know where else to look), yet I still get:

WARNING in Invalid animation value at 10069:24. Ignoring.
WARNING in Invalid animation value at 10139:24. Ignoring.
WARNING in Invalid animation value at 10228:24. Ignoring.
WARNING in Invalid animation value at 10316:24. Ignoring.

[zicaros]

Yeah, these warning so a bit annoying.
WARNING in Invalid animation value at 211:12. Ignoring.

Please tell more information of warning

I think it is related this comment in #11802 of @hansl. Our Jenkins job fails after receiving a trivial CSS warning after a successfull build.
