This is my test area for webdev. I keep a collection of code here, mostly for my reference. Also if i find a good link, i usually add it here and then forget about it. more...

Random CSS Property

clamp()

The clamp() CSS function clamps a value between an upper and lower bound. clamp() enables selecting a middle value within a range of values between a defined minimum and maximum. It takes three parameters: a minimum value, a preferred value, and a maximum allowed value. The clamp() function can be used anywhere a <length>, <frequency>, <angle>, <time>, <percentage>, <number>, or <integer> is allowed.
