Use dashed border style for outline  Draw background-color with  before or  after pseudo element    Note  This method will allow you to have maximum browser support   Output Image      x000D   x000D     box-sizing  border-box   x000D   x000D   box   x000D    border  1px dashed  fff  x000D    position  relative  x000D    height  160px  x000D    width  350px  x000D    margin  20px  x000D    x000D   x000D   box before   x000D    position  absolute  x000D    background  black  x000D    content      x000D    bottom  -10px  x000D    right  -10px  x000D    left  -10px  x000D    top  -10px  x000D    z-index  -1  x000D    x000D   lt div class  box  gt  x000D   x000D   lt  div gt  x000D   x000D   x000D

You may also use box-shadow and add transparency to that dashed border via background-clip to let you see body background   example   x000D   x000D  h1   x000D    text-align  center  x000D    margin  auto  x000D    box-shadow  0 0 0 5px  1761A2  x000D    border  dashed 3px  1761A2  x000D    background  linear-gradient  1761A2   1761A2  no-repeat  x000D    background-clip  border-box  x000D    font-size  2 5em  x000D    text-shadow  0 0 2px white  0 0 2px white  0 0 2px white  0 0 2px white  0 0 2px white  x000D    font-size  2 5em  x000D    min-width  12em  x000D    x000D  body   x000D    background  linear-gradient to bottom left  yellow  gray  tomato  purple  lime  yellow  gray  tomato  purple  lime  yellow  gray  tomato  purple  lime   x000D    height  100vh  x000D    margin  0  x000D    display  flex  x000D    x000D    first-line   x000D    color  white  x000D    text-transform  uppercase  x000D    font-size  0 7em  x000D    text-shadow  0 0 x000D    x000D  code   x000D    color  tomato  x000D    text-transform  uppercase  x000D    text-shadow  0 0  x000D    x000D  em   x000D    mix-blend-mode  screen  x000D    text-shadow  0 0 2px white  0 0 2px white  0 0 2px white  0 0 2px white  0 0 2px white x000D    x000D   lt h1 gt transparent dashed border lt br  gt  x000D     lt em gt with lt  em gt   lt code gt background-clip lt  code gt  x000D   lt  h1 gt  x000D   x000D   x000D    Pen to play with  render in firefox

IE doesn t support outline-offset so another solution would be to create 2 div tags  one nested into the other one  The inner one would have a border and be slightly smaller than the container    x000D   x000D   container   x000D    position  relative  x000D    overflow  hidden  x000D    width  400px  x000D    height  100px  x000D    background   000000  x000D    padding  10px  x000D    x000D   inner   x000D    position  relative  x000D    overflow  hidden  x000D    width  100   x000D    height  100   x000D    background   000000  x000D    border  1px dashed  ffffff  x000D    x000D   lt div class  container  gt  x000D     lt div class  inner  gt  lt  div gt  x000D   lt  div gt  x000D   x000D   x000D
