Overriding sclogin default.css to change username width?

We have a full Themeing the SCLogin module document, which has more of the gory details about what to do. The best answer is:
* Copy media/sourcecoast/themes/sclogin/default.css to /templates/<YOUR_JOOMLA_TEMPLATE>/html/mod_sclogin/themes/default.css
Edit away.

Better yet, copy that file to /templates/<YOUR_JOOMLA_TEMPLATE>/html/mod_sclogin/themes/my-custom-theme.css and select that theme in the SCLogin module parameters. The benefit of that is it will be easier to switch between "Default" and "My Custom Theme" in the future so that you can more easily detect any changes we make in the next release(s) of SCLogin. While your changes won't be overwritten going forward, you will want to ensure that you try to incorporate any changes we make into your custom theme.

I hope that helps, but if you have any questions, just let me know!

In the Login View Settings, the first option (I believe) is "Theme". Use that drop-down and (hopefully) you'll see your new file in there. If not, let me know.

No problem for the help. That's what we're here for. If you have any other questions, just let me know.

Finally, if you haven't already, please consider leaving a rating and review for SCLogin, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:
