As an additional remark... to me it seems more logical to implement the flexbox solution as the standard, and use the polyfill in cases where flexbox is unsupported instead of the other way around. Since support seems quite universal at this time.
I'm currently setting up a website that will use Wordpress as a headless CMS, pulling only the API data into my Vue.js frontend. Which works in combination with Laygridder with some adjustments here and there, but what doesn't seem to be working is flexbox/alignment. Elements with classes like "lg-align-bottom" and "lg-align-top" are unaffected, lacking their usual flexbox css styling.
Usually this seems to be achieved by some polyfill functions which are obviously not loaded in my setup. Is there a smart solution for this? Or wil it require me to incorporate a version of the polyfill in my frontend manually?
