Question

css

Good evening!
Styles are not pulled up in the browser Mozila Firefox and IE patient https://www.decorbazar.ru/
Who has any thoughts?

Answer 1

Styles are connected correctly, if they were not connected, then the site would be displayed the same in any browser (i.e. without styles)

Andrey Bely , but still they are connected incorrectly)
As RAX7 noted, the support for the approaches used is weak.
In addition, there is no point in preloads without their subsequent declaration. And the approach used, obviously picked up on some site of optimizers, besides that it smells, it still doesn’t work (look at PagesSpeed).
It would be easier and better to collect styles (which are possible at the front level) into one file, or even break them into critical and non-critical ones and drive the latter at the JS level.
Moreover, loading styles with a label (the amount after ? in the link), those styles that will not logically change, is stupid.
Against the background of all this, “Quickly with 1C-Bitrix” looks very hilarious.
And yes, IE is dead, remember.
