custom css in "enfold restaurant theme"

Hi.
I import restaurant theme in clean wordperess
I would like to have my first section in center container (like other section).
All of my sections are in center and have css style like : max-width:1310px.

But in my first section I have extra style:
.home #av_section_1 .container{
max-width:none !important;
padding:0px 0px !important;
}

where cam I find and change it. (it’s not in enfold custom css!)
