[sass|scss] support css variables to property

[tamascsaba]

If I use css variables:

.element {
  --main-bg-color: brown;
}

sass-lint throw: no-misspelled-properties

With the version 1.10 I am having following error when using css variables:

413:1  error  Please check validity of the block starting from line #413  Fatal

So it is not an enhancement anymore but an issue

Have the same issue. Since CSS custom property not equal to Sass variables we have too many reasons to have both in sass file.

Hi guys, you need to report this to Gonzales-pe which is the AST we use.

The fatal errors you're encountering are because the AST doesn't currently support CSS variables / modules

Seems like this issue is related tonyganch/gonzales-pe#197

If this is any help to anyone, I've managed to get around this by changing

:root {
  --custom-var: white;
}

to

:root {
  #{--custom-var}: white;
}

Not great but it suppresses the error thrown for the time being. I've not found any issues yet.
