Text border using css (border around text)

Use multiple text shadows:

text-shadow: 2px 0 0 #fff, -2px 0 0 #fff, 0 2px 0 #fff, 0 -2px 0 #fff, 1px 1px #fff, -1px -1px 0 #fff, 1px -1px 0 #fff, -1px 1px 0 #fff;

body {
  font-family: sans-serif;
  background: #222;
  color: darkred;
  }
h1 {
  text-shadow: 2px 0 0 #fff, -2px 0 0 #fff, 0 2px 0 #fff, 0 -2px 0 #fff, 1px 1px #fff, -1px -1px 0 #fff, 1px -1px 0 #fff, -1px 1px 0 #fff;
}

<h1>test</h1>

Alternatively, you could use text stroke, which only works in webkit:

-webkit-text-stroke-width: 2px;
-webkit-text-stroke-color: #fff;

body {
  font-family: sans-serif;
  background: #222;
  color: darkred;
  }
h1 {
  -webkit-text-stroke-width: 2px;
-webkit-text-stroke-color: #fff;
}

<h1>test</h1>
