inline-block , why do we add -5px margin-right

if the max-width of the page is 100% and one of the two columns is 60% and the other 40% why do i need to add margin-right to make them sit side by side?

* {
  box-sizing: border-box;
}

#wrapper {
  max-width: 100%;
  margin: 0 auto;
}


.col {
  display: inline-block;
  padding: 10px;
  margin-right: -5px;
  vertical-align: top;
  height: 200px;
}

.primary-content {
  background: lightblue;
  width: 60%;
}

.secondary-content {
  background: pink;
  width: 40%;
}

Inline-block elements have some default white space associated with them. CSS Tricks wrote a whole article on ways to get rid of this space. Using negative margins is a common method for removing unwanted space between inline-block elements.
