Can css in a gnome-shell-extension be overridden by css in a shell theme?
E.g. "Dash to Panel" has the following lines in its stylesheet.css:
#dashtopanelScrollview .app-well-app:hover .overview-icon,
#dashtopanelScrollview .app-well-app:focus .overview-icon {
background: none;
}
#dashtopanelScrollview .app-well-app:hover > :first-child,
#dashtopanelScrollview .app-well-app:focus > :first-child {
background-color: rgba(238, 238, 236, 0.1);
}
When I place the same selectors or more specific selectors in my gnome-shell.css and try to change the background of .overview-icon, the css from Dash to Panel's stylesheet.css is used instead.
Given the CSS you provided, I was able to force the styling by using the important rule.
