  1. Thanks for the greate article, but i have small question about button, can you explain it. Why in body must have display: grid?. When i remove display: grid from body, the pseudo element display on the left of button, but when use display: grid, the pseudo element will disappear. and Sorry my english grammer is not good. Have a nice day

  2. Thanks for this great work.
    In the example with “hover me”, the bt css property shouldn’t be defined on “inline” otherwise the property “overflow” doesn’t work.
    “display:inline-block” inside bt section works.
