Please make those borders darker

i am new here. Browser as you can see is the latest in Opera.
I believed the “custom input” had to be clicked in, but it wasnt accepting clicks, since the box was unchecked. Couldnt see the check-box until i used inspection tools.

TIL: learnt that not giving any inputs(custom or not), triggers SIGTSTP

I use opera and I face no problem seeing that.

Tried changing my laptop’s contrast, tilted the screen backwards, tried everything buddy. You got some healthy eyes!

Only after editing the page’s css for a darker background, i can see all light borders, like the comment divs. And again… the checkboxes. These have to be changed to arleast be like bottom border of this page’s header

Whatever, that’s not a big concern, I don’t even use opera anymore.
