How to concatenate Sass variables

Question

How can I concatenate a Sass variable?

This is the the code in the scss file.

$url = 'siteurl.com';

#some-div{
    background-image: url(+ $url +/images/img.jpg);
}

I want the result in the CSS file to be:

#some-div{
    background-image: url('siteurl.com/images/img.jpg');
}

I found this question, but it didn't worked for me: Trying to concatenate Sass variable and a string

Answer 1

Multiple issues here, the correct syntax is

$url: 'siteurl.com';

#some-div{
  background-image: url($url + '/images/img.jpg');
}

• When you assign a value to the variable, you need to use : and not =
• You should quote the image path as it's a string.
• Remove the stray + symbol before $url
