I'm using the latest versions of Community Builder (2.0.9) and CB Connect (7.0.0-Beta.3) on my site, and am wondering - is there any way to have the "sign in with facebook" (for example) page open up in a pop up as opposed to a full page login screen in the current window? In other words, I'd like for the facebook login screen to show as a pop-up of sorts when my users click "sign in with facebook" (or any of the other social media networks). Is this possible to do?
You can't, it doesn't utilize popup usage for many reasons. It doesn't work on mobile, many browsers will block the popup, and it requires a JS hook to wait for the window to close before an internal redirect can be made to perform the login behavior on the main window.
Also, is it possible to change the color of the buttons to something other than the default blue?
Each button has a unique CSS class based off its provider so it can be styled however you like using those classes (e.g. cbConnectButtonFacebook). Right click and inspect element in Chrome or Firefox for their classes. Please note their colors are based off the social sites guidelines.
