What is the difference between pixel and percentage?

Question

How we change pixel into percentage? Like 1% mean 1pixel or 120 = to 1%?

Answer 1

• % is relative unit of measurement in css (divide the total width or hight of screen in 100 parts and a single part will be 1%)
• px is absolute ( every device may have different pixel of width and height)
You can use javascript to cheque how much pixel does 1 percent of screen contain.
to get it use the code
var width = window.innerWidth;
console.log(width/100)
