加上js代码就可以了
html代码
<span id="blink">闪烁文字</span>
JavaScript代码：
<script type = "text/javascript" >
function blinklink() {
if (!document.getElementById('blink').style.color) {
document.getElementById('blink').style.color = "red"
}
if (document.getElementById('blink').style.color == "red") {
document.getElementById('blink').style.color = "black"
} else {
document.getElementById('blink').style.color = "red"
}
timer = setTimeout("blinklink()", 100)
}
function stoptimer() {
clearTimeout(timer)
}
blinklink()
</script>
<!doctype html><html lang="en">
