Mixing cookies and css with php

So I have really simple css file that is generated based on cookie that is fetched using php. Whole css is also displayed using php so it

<?php header("Content-type: text/css");
$rand = $_COOKIE['randTopic'];

echo '
body {
    margin-top: 50px;
    margin-bottom: 50px;
    background: none;
}

.full {
  background: url("http://loremflickr.com/1920/1080/' . $rand . '") no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  }
';
?>

Loremflickr is just a service that gives me random image from flickr, I can also choose topic what I am doing actually. So the output css looks exactly like this:

body {
    margin-top: 50px;
    margin-bottom: 50px;
    background: none;
}

.full {
  background: url("http://loremflickr.com/1920/1080/wall
") no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  }

As you can see there's a linebreak that I didn't really want, no idea why it's here. I think it could cause the problem, what do you think?

Thank you kindly in advance for any help.

Quick fix for that is to use trim() function on data from cookie.

But first of all I would check why is there line break. Inspect your code.

trim() the variable in your output - 

echo '
....
background: url("http://loremflickr.com/1920/1080/' . trim($rand) . '") no-repeat center center fixed;
....
';
