hi, i'm newbee and i test the framework on my NAS (http://siege.gigarun.net/helix ) and test optimisation with https://yellowlab.tools/
discover this = https://yellowlab.tools/result/fqszsne90i/rule/cssOldPropertyPrefixes
egaly test innovate http://siege.gigarun.net/innovate and it's worse https://yellowlab.tools/result/fqt1939nae
My question : can i reduce css complexity and is old prefixes removables from css (components\com_sppagebuilder\assets\css) ? if yes how to keep this removed in case of helix update ?
thx for help
