The text-stroke property

The text-stroke property sets the color and thickness of text character outlines. As a value, the property should be given the outline thickness and the outline color separated by a space.

Syntax

cssselector {
  text-stroke: outline thickness and color;
}

Basic example

Simple text outline:

html<div class="stroked-text">
  Lorem ipsum dolor sit amet
</div>

css.stroked-text {
  font-size: 48px;
  font-weight: bold;
  -webkit-text-stroke: 2px red;
  text-stroke: 2px red;
}

Результат:

Outline only

Now let's make the text color match the background color (white in our case). As a result, only the outline will remain:

html<div class="stroked-text">
  Lorem ipsum dolor sit amet
</div>

css.stroked-text {
  font-size: 48px;
  font-weight: bold;
  color: white;
  -webkit-text-stroke: 2px black;
  text-stroke: 2px black;
}

Результат:

Gradient outline

Let's create a gradient outline using the background-clip property:

html<div class="gradient-stroke">
  Lorem ipsum dolor sit amet
</div>

css.gradient-stroke {
  font-size: 42px;
  font-weight: bold;
  background: linear-gradient(to right, #ff8a00, #e52e71);
  -webkit-background-clip: text;
  background-clip: text;
  color: transparent;
  -webkit-text-stroke: 1px #333;
  text-stroke: 1px #333;
}

Результат:

Multiple outline

Double outline effect using text-shadow:

html<div class="double-stroke">
  Lorem ipsum dolor sit amet
</div>

css.double-stroke {
  font-size: 40px;
  color: white;
  -webkit-text-stroke: 3px #000;
  text-stroke: 3px #000;
  text-shadow: 
    0 0 5px #000,
    0 0 10px #000;
}

Результат:

Animated outline

Adding an animation to change the outline:

html<div class="animated-stroke">
  Lorem ipsum dolor sit amet
</div>

css.animated-stroke {
  font-size: 38px;
  color: white;
  -webkit-text-stroke: 1px #ff0000;
  text-stroke: 1px #ff0000;
  animation: pulse 2s infinite;
}

@keyframes pulse {
  0% { -webkit-text-stroke: 1px #ff0000; text-stroke: 1px #ff0000; }
  50% { -webkit-text-stroke: 3px #ff0000; text-stroke: 3px #ff0000; }
  100% { -webkit-text-stroke: 1px #ff0000; text-stroke: 1px #ff0000; }
}

Результат:
