Editor warnings re size expressed in vh

cager · 10-14-2014, 09:25 AM

Recently I am getting epub books which the Editor Check Book is giving red warnings for invalid CSS 2.1 when the property is like
height: 100vh;

I understand that this is a new measurement unit in CSS3.

I am converting the epub to AZW3 for a basic Kindle.

Do I:
1. Ignore;
2. Delete the line so there is no reported error;
3. Change the 100vh to something else?

vh is not a valid unit in CSS 2.1. WHat to do with it depends on the target device(s) you are amking the book for. If you can check it works, ignore the message, if you check and find it doesn't work, delete/replace it.

Thanks kovidgoyal for a quick response.
Hope all is well with the baby and you are getting some sleep.

Downside to the editor is that before it was there all I worried about was - could I read the book. Now I look for potential problems where there are probably none.
