calc function #56

Open Nicasso opened 8 years ago

Nicasso commented 8 years ago

Hello,

I don't know if it is a bug or that the calc function is just not supported yet. But the calcfunction is not being parsed, if it is used, the whole rule set is ignored. It looks like it is the only function which is not working since functions like linear-gradient do work correct.

So this whole ruleset will be ignored. .background2 { width: calc(100% - 100px); background: linear-gradient(red,yellow,blue); }

And this one will work. .background2 { background: linear-gradient(red,yellow,blue); }

Regards, Nico

Same goes for the alpha function. 

  filter: alpha(opacity=60);

This declaration will be ignored.

Unfortunately, calc() is not supported yet and for the first look, it will require quite significant modifications in the value processing, since it can actually produce different value types (lengths, angles, integers, etc.) The filter: property would be probably easier to implement; however it seems to be quite an experimental technology at the moment.

I know it has been a long time but finally, there is now an experimental support for calc() added in the master branch.
