easy contact form plugin

I can’t seem to adjust the width of the form. I’m trying to place an image next to the form in the normal flow of elements on the content page but it appears that the form uses a clearfix styling attribute, pushing any objects in succession beneath it. To work around this, I need to place the image on the page using absolute positioning. When the width of the screen decreases and the inherent responsive design features kick in, the absolute positioned image upsets the adjusting flow of content. Any ideas?
