Variables in Media queries in Sass

Reading an article about variables in media queries in Sass i saw this code:

You're not limited to using variables in the numerical part of a @media test. Go ahead and set the whole test as a variable. (Note the need for the interpolation braces #{})>

$information-phone: "only screen and (max-width : 320px)";

@media #{$information-phone} {
  background: red;
}

Unfortunately there is no further explanation about interpolation braces #{}

Can anyone give some more information about it?

P.s. here is the article itself http://thesassway.com/intermediate/responsive-web-design-in-sass-using-media-queries-in-sass-32

Hi K SA,

You can find more information about interpolation in Sass at the below link.

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#interpolation_

In the past you needed interpolation a lot more then now as the Sass compiler has been upgraded vastly since the release of 3.2 so you don't need #{} everywhere in your code, for your example above you can simply use the variable you have inline after @media.

@media $information-phone {
  background: red;
}

Interpolation braces #{} evaluate a statement within the braces and print it's result. so if you place a variable in the interpolation braces, the value of the variable will be evaluated and used in its place. 

$information-phone: "only screen and (max-width : 320px)";

@media #{$information-phone} {
  background: red;
}

/* Will evaluate to: */

@media only screen and (max-width : 320px) {
  background: red;
}
