Change style of element within shadow dom without variable ionic-v4

How to change those element styling which is within shadow dom and dont have variables?

The only “proper” way to do this would be to make a request for Ionic to add a variable for whatever it is you want to change, or add the variable yourself and submit a pull request to Ionic (I’m told they are accepting most PRs that add variables).

Technically, it is possible to inject styles into the Shadow DOM, but this is not recommended. If you use Ionic’s components the way they are intended you can be sure they won’t break in the future, if you use “hacks” to circumvent this then there is not guarantee that future updates won’t break what you’ve done.

yep but it’s not about few variables, there are lot. and for component creation in v4, getting errors. components not working. can u look into this please?
