Input cursor that is blinking

Question

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="|"/>

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

Answer 1

Just add autofocus attribute. See the link here

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

The autofocus attribute is a boolean attribute. When present, it specifies that an element should automatically get focus when the page loads.

Answer 2

Try this solution

<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; }
}
