title: When you value Flex-Basis as a percentage, why doesn't it do the same with Flex Grow?
body: <p>I have also examined various documents but could not understand the logic in the code below. Let's say we gave 25% for Flex-Basis. As you can see when we give Flex-Grow 0.25 to the other box with the same features, the dimensions are different, but shouldn't it be the same?</p>
  <p>Also, what is the difference between using the flex basis as a percentage and using flexible growth? Thank you very much for your interest in advance.</p>
