PageSpeed Insights can't realize CSS Cascade Layers.

[meistudioli]

Hi,

I use PageSpeed Insights to check web page. I found my CLS score is ugly then I realize CSS losing (from preview). I use CSS Cascade Layers for web page. I wonder can't PageSpeed Insights realize CSS Cascade Layers ?

Here comes my style code.

<style>
@layer reset, defaults, patterns, components, utilities, overrides;

@import url('css/auction/reset.css') layer(reset.reset);
@import url('css/auction/defaults.css') layer(defaults.vars);
@import url('css/auction/header.css') layer(components.header);
@import url('css/auction/footer.css') layer(components.footer);
@import url('css/auction/buttons.css') layer(components.buttons);
@import url('css/auction/carousel.css') layer(components.carousel);
@import url('css/auction/shortcuts.css') layer(components.shortcuts);
@import url('css/auction/heros.css') layer(components.heros);
</style>

Thank you for reading.
