Write a function, called px-to-rem, that accepts the parameters $target and $context. Set the default value of $context

How can I get this to work??

$base-font-size: 16px;
$context: $base-font-size;

// Write your function here
@function px-to-rem($target, $context){

}
´´´

```style.scss
$base-font-size: 16px;

// Write your function here
@function px-to-rem($target, $context){

}

Hi Philip,

The assignment is to set a default value for $context. 

$base-font-size: 16px;
@function px-to-rem($target, $context: $base-font-size){

}

By writing $context: $base-font-size you are telling the compiler that if the px-to-rem() is called without the second $context argument, that it should default back to $base-font-size. Which is a variable defined as 16px. Cool huh?
