Question

Hi @masterpiece8931

Some providers have strict guidelines for the appearance of the social buttons, and we try to design the style of all social buttons according to the official guidelines.

Because of these reasons, we don’t really want to give people settings that they can use to modify the styles, otherwise they would make the buttons no longer comply with the mentioned guidelines.
A typical example is Meta ( Facebook ) App review process. If their staff reviews your App, and they find your custom social buttons violating their Sign In Branding guidelines, they will most likely disable your Facebook App. And they will only enable your App again, after you made the modifications they asked, and they approved the changes.

Here I need to mention that I have also met customers where the social buttons were completely customized and their App hasn’t been disabled. But I also met cases where the social buttons only had a little but style modifications, yet Facebook disabled their App. So I assume it depends on the person who reviews your site.

In either ways, if you don’t mind risking your App, then with a custom CSS like this you could customize the border radius of your social buttons:

div.nsl-container .nsl-button{
  border-radius: 99px!important;
}

but as I mentioned above I don’t suggest modifying the design.

Best regards,
Laszlo.
