I find margin-block-end only works on v87+ in caniuse, I'm not sure if this is the best solution.

What is the lowest version it should be?

I think having proper localization (which includes RTL design) is more important than supporting old browsers anyways.

Nearly two years on, we can look at the latest figures on caniuse, both margin-inline-end and margin-block-end are supported by over 96% of browsers.
Besides, antd had already used margin-inline-end in their components https://github.com/search?q=repo%3Aant-design%2Fant-design+margin-inline-end&type=code.

I think it's time for us to import them in ng-zorro, WDYT? @lppedd

[lppedd]

@Laffery yup, I agree. Generally speaking I'm ok with supporting older browsers, but I always prioritize the code and how easily a feature can be implemented with new options.
