I am trying to create a variable that is equal to nothing. I have tried the following..
$false:null; -and-
$false:" "; What I am trying to use it with is this...
@mixin myMixin($myVariable:"", $myOtherVariable){ $false:null; @if $myVariable == $false { //do something } @if $myVariable != "" { //do something else } } @include myMixin("", $myOtherVariable); I am using two variables for this example, but I plan to have more than two.
Basically what I want to do is have the option to exclude a variable without having to use empty quotes. And the problem with $false: ""; Is that it still expects empty quotes. So I am wondering if there is something built into SASS to designate "null / or nothing". I thought it might be null. But that doesn't seem to be the case..

Description. You can set the default values for variables by adding ! default flag to the end of the variable value. It will not re-assign the value, if it is already assigned to the variable.
Sass variables are simple: you assign a value to a name that begins with $ , and then you can refer to that name instead of the value itself.
To make a dynamic variable is not possible in SASS as of now, since you will be adding/connecting another var that needs to be parsed once when you run the sass command. As soon as the command runs, it will throw an error for Invalid CSS, since all your declared variables will follow hoisting.
null or false will work (null is new in the latest version of Sass). Both will work for your example. The only advantage of null is that it disappears if you use it with a property.
