Hey,
So I couldn't find a recent answer to this and was wondering if it's still working.

I have a .css linked through dropbox as (minus the &)

<&link rel="stylesheet" type="text/css" href="https://dl.dropbox.com/s/9x8kxxoftvpioxv/nextsmall.css?dl=0" />

the contents of the css is (minus the &)

a[href&="139547"]>div.cave-grid>img {
content: url('https://i.postimg.cc/kMsDMhyW/maternityden.png')!important;
}


Yet it won't show the replaced image. I tried it with and without my overall theme and even tried adding it into the existing theme's css at one point.

Is there something really stupid I'm doing wrong, and would someone be so kind as to point it out? I've been messing with it for over a week and it's bugging me like crazy.

Thanks
C
