Custom CSS & Theme Design
1

Can someone please help me how I can change the red marked with which command in my theme.css.

I would like to make this gray border white like the other borders.

So where the red arrows were cut off and how can i make it so that it is not round but square?

Please in color scheme dark if it is necessary.

Many thanks if anyone can help.

Same here. I’d like to know how to change the color of those borders. I almost can’t see them. Thank you.

In case you still want this…

.theme-dark {
    --modal-border-color: white;
}
.modal.mod-settings {
    border-radius: 0;
}
