XF 1.2 Where to locate flexile css file

[Masterofsixpack]

Hello,
I have a xenforo website that contains xenporta and flexile theme. I went to Flexile Content Background in general style properties and uploaded the image. Theres only a small portion of it, how do I stretch it to cover the whole background besides header. Is there a css file for this? I looked everywhere on the forums and cant find my answer.

You will need to ask your question in the Flexile thread as it is a non-standard style.
