最初的netscape <blink>具有80％的占空比。这很接近，尽管实数<blink>仅影响文本：
.blink {
animation: blink-animation 1s steps(5, start) infinite;
-webkit-animation: blink-animation 1s steps(5, start) infinite;
}
@keyframes blink-animation {
to {
visibility: hidden;
}
}
@-webkit-keyframes blink-animation {
to {
visibility: hidden;
}
}
This is <span class="blink">blinking</span> text.
