Login Page Background

Hello all,

I have a website that I am currently working on and I loved this plugin. However, I couldn’t get rid of this #f7f7f7 background comes with the login shortcode.

Here’s a screenshot https://puu.sh/FzmG3/60b0dffc25.png to give you more insight.

Can anybody help me to make it transparent, please? I also need the labels in white if possible 🙁

The page I need help with: [log in to see the link]
