css - sass background mixins using url -

this question has answer here:

guys create background mixin instead writing repeated url

 @mixin bgimage($name){   $url:"../images/$name.png";  background: url($url);}

and,it never accept valuee $name variable

i called

     @include bgimage(name.png);

and in css output came wrong this

     background: url("../images/$name.png");

is there way write url in mixin ? ot how in short way

try variable interpolation of #{$name}

@mixin bgimage($name) {   $url:"../images/#{$name}.png";   background: url($url); }

and pass filename, without extension, mixin parameter:

@include bgimage(your-png-file-without-extension);

since appended in $url variable of mixin
