  flex-wrap: wrap;

}

#about ul {
  display: flex; /* Makes use of flex box, which is sort of a new way to do grids (kinda simply said) */
  justify-content: center; /* makes every child element start from the center and then outwards */
  flex-wrap: wrap; /* whenever the content inside the <ul> is bigger than the window size, it should wrap to a new line, thus the <li> elements go underneath each other when on mobile */
}
