Can I style the share boxes differently?

Yes, you can definitely change the styling if you’d like.

Shared Counts includes some pre-built styles which you can customize yourself using CSS in your theme.

Or you can register new style options using the shared_counts_styles filter. Here’s a tutorial: https://sharedcountsplugin.com/2019/05/13/creating-new-button-styles/

Hello,
following on from this topic.

I was wondering if you could advise me on how to change the colour of my share buttons to black in css?

Here is a link to a page of my site.

Thankyou!

@rosiemalachi, you could add the following css to your theme.
Appearance -> Customise -> Additional CSS

.shared-counts-wrap.style-buttons .shared-counts-button {
  background-color: #000000 !important;
}

.shared-counts-wrap.style-buttons .shared-counts-button:hover {
  background-color: #323232 !important;
}

great!
That has worked a treat.
thanks for your help ??
