I believe that in order to better your knowledge base, it takes a lot of failing in order to succeed. I don't consider anything a failure as long as you get back up and you learn from your own mistakes.

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.
