Hey Oren,
first of all, thank you for the purchase!
The “max-width” declaration you’re after is on line 133 of the “responsive.css” file in the theme’s root folder ;) I’ve put the CSS that governs the fluid layout into a separate file in this case.
If you wish to make the website stretch the entire width of the screen, you can add the following CSS into the “Style: Add Custom CSS” tab of the Theme Options panel (or directly change the “responsive.css” line that I mentioned above):
body .container {
max-width: 100%;
margin: 0 20px;
}
Sincerely,
Andrii / Satori Studio
