I understand a lot of what is going on in the CSS file main.css – I know it is being post processed to create a final CSS, and that there are lots of variables that allow for lots of flexibility. Something I have not seen before, and am trying to understand is the square bracket notation in this snippet for the Simple theme:
[type=text],
[type=url],
[type=tel],
[type=number],
[type=email],
[type=search],
textarea,
select { ...
These might be css features I am not aware of, or something unique to Publii.
Looking for some enlightenment.
Thanks
