<强> Canvas example

var canvas = document.getElementsByTagName("canvas")[0],
    ctx = canvas.getContext('2d');

ctx.font="75px verdana";
ctx.shadowColor="black";
ctx.shadowBlur=10;
ctx.lineWidth=10;
ctx.strokeStyle = "white";
ctx.strokeText("HELLO",25,100);
ctx.shadowBlur=0;
ctx.fillStyle="red";
ctx.fillText("HELLO",25,100);

<canvas id="c" width="300" height="130"></canvas>

CSS示例

.text {font-size: 3em;
  -webkit-text-stroke: 2px white;
  -webkit-text-fill-color: black;
  -webkit-animation: fill 1s infinite alternate;
text-shadow:2px 2px 10px #000;
}

</div>
