what does display inline-block do? code example

Example: what does display inline-block do?

/*Compared to display: inline, the major difference is that
display: inline-block allows to set a width and height on the element.

Also, with display: inline-block, the top and bottom margins/paddings are
respected, but with display: inline they are not.

Compared to display: block, the major difference is that
display: inline-block does not add a line-break after the element,
so the element can sit next to other elements.

The following example shows the different behavior of
display: inline, display: inline-block and display: block: */


span.a {
  display: inline; /* the default for span */
  width: 100px;
  height: 100px;
  padding: 5px;
  border: 1px solid blue;
  background-color: yellow;
}

span.b {
  display: inline-block;
  width: 100px;
  height: 100px;
  padding: 5px;
  border: 1px solid blue;
  background-color: yellow;
}

span.c {
  display: block;
  width: 100px;
  height: 100px;
  padding: 5px;
  border: 1px solid blue;
  background-color: yellow;
}
