输入光标闪烁 [英] Input cursor that is blinking

问题描述

我无法使输入光标闪烁。如何制作动画，使光标 |输入字段（占位符）中的指示灯持续闪烁。
我的代码是这样的：

i am having trouble with making the input cursor to blink. How do you make an animation that the cursor "|" inside the input field (placeholder) keeps blinking. The code that i have is this:

<input type="text" class="rq-form-element" placeholder="|"/>

我不知道该如何开始。有建议吗？

I have no idea on how to get this even started. Any suggestions?

推荐答案

尝试此解决方案

<div class="cursor">
<input type="text" class="rq-form-element" />
<i></i>
</div>

CSS

.cursor {
    position: relative;
}
.cursor i {
    position: absolute;
    width: 1px;
    height: 80%;
    background-color: gray;
    left: 5px;
    top: 10%;
    animation-name: blink;
    animation-duration: 800ms;
    animation-iteration-count: infinite;
    opacity: 1;
}

.cursor input:focus + i {
    display: none;
}

@keyframes blink {
    from { opacity: 1; }
    to { opacity: 0; }
}
