Traditionally min(something1, something2) means minimum from this values.
So this notation will confuse those who knows e.g. JavaScript where min is
function.
In our case min is not a function but a parameter-constrain.
Min/max constraints is a property of relative unit values like em,ex,%,%%.
Min/max are not independent entities.
font-size: 3em (min:10pt, max:20pt);
Choices are:
1)
width: 50% (min:20px, max:100px)
here 50% is a function name and at the same time its main value.
It calculates as occurs calculation of percentage - in runtime. That is main
difference
with calc() approach - it calculates once.
Also we may consider different brackets like
50% [min:20px, max:100px]
50% {min:20px, max:100px}
For clearnes of formal grammatic/syntax rules "( ... )" is better.
Try to imagine that in document having 5 independent styles applied someone
set e.g. p{ min-width:50%; max-width:20em } at the very first sheet.
Nightmare.
