The styles, as they are will work. the problem is that, with ja blokk, when the dark setting on the site is used, the color scheme on jomsocial remains light. your new templates are too beautiful to use the jomsocial themes as they are.
see: https://news.national-coalition.net. and select the dark template option in the top left position.
If transparency or opacity settings were added to jomsocial, then jomsocial could be adjusted to match the template’s color scheme much better.
i use the default theme, or the js-shadow theme.
