hi, this is the code for the body in global.css:

body {
background-image: url(images/titanic.jpg);
opacity: 75%;
bbackground: #2f3236;
color: #E4E4E4;
text-align: center;
line-height: 1.4;
margin: 0;
font-family: Tahoma, Verdana, Arial, Sans-Serif;
font-size: 13px;
overflow-y: scroll;
}


the picture i have put in is "titanic.jpg"
and it is 3840x2160 pixels, while my monitor
is a full-hd 21/9.

what i want is to have the full picture inside my
forum, while i have to scroll up and down, because
i have many categories and forum, but i don't want
to scroll left and right in the page.

thank you very much.

just use background-size properties

 background-size: cover;
background-position: center;
