Move placeholder above the input on focus - html

Question

I'm looking for css code that move the placeholder text above the input on focus. I found this code here. This code is perfect but my input tag is wrapped inside <span> and for that reason general sibling selector is not working. Any ideas how to edit this css?
<div>
<span class='blocking-span'>
<input type="text" class="inputText" />
</span>
<span class="floating-label">Your email address</span>
</div>

Answer 1

You can use the CSS pseudo-selector :placeholder-shown in this case to detect when to move a fake placeholder out of the way. See example below:
label {
margin:20px 0;
position:relative;
display:inline-block;
}
span {
padding:10px;
pointer-events: none;
position:absolute;
left:0;
top:0;
transition: 0.2s;
transition-timing-function: ease;
transition-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1);
opacity:0.5;
}
input {
padding:10px;
}
input:focus + span, input:not(:placeholder-shown) + span {
opacity:1;
transform: scale(0.75) translateY(-100%) translateX(-30px);
}
/* For IE Browsers*/
input:focus + span, input:not(:-ms-input-placeholder) + span {
opacity:1;
transform: scale(0.75) translateY(-100%) translateX(-30px);
}
<label>
<input placeholder=" ">
<span>Placeholder Text</span>
</label>

With the given links CSS etc, simply move the floating-label inside the blocking-span.
By using position: relative on the div the floating-label will still re-position as if it were outside the blocking-span
div {
position: relative; /* make label relate to div */
padding-top: 10px; /* make space for label */
}
.inputText {
font-size: 14px;
width: 200px;
height: 25px;
}
.floating-label {
position: absolute;
pointer-events: none;
left: 15px;
top: 18px;
transition: 0.2s ease all;
}
input:focus ~ .floating-label,
input:not(:focus):valid ~ .floating-label {
top: -6px;
}
<div>
<span class='blocking-span'>
<input type="text" class="inputText" required/>
<span class="floating-label">Your email address</span>
</span>
</div>

If you change html structure then your reference example is work but if you don't want change html structure then you need to write little jQuery. You can check this.
$(function(){
$('.blocking-span input').on('focus', function(){
$(this).parents('.parents-elm').addClass('foucs-content'); // When focus the input area
});
$(document).mouseup(function(e){
if($(e.target).parents('.blocking-span input').length==0 && !$(e.target).is('.blocking-span input')){
$('.parents-elm').removeClass('foucs-content');
}
});
});
div{
position: relative;
}
.blocking-span{
display: block;
}
.blocking-span input{
border: 1px solid #eaeaea;
height: 80px;
padding-top: 30px;
padding-left: 20px;
padding-right: 20px;
width: 100%;
}
.floating-label{
display: inline-block;
font-size: 15px;
left: 20px;
line-height: 20px;
position: absolute;
top: -webkit-calc(50% - 10px);
top: -moz-calc(50% - 10px);
top: calc(50% - 10px);
transition: top 0.3s ease-in-out 0s;
}
.foucs-content .floating-label{
top: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="parents-elm">
<span class='blocking-span'>
<input type="text" class="inputText" />
</span>
<span class="floating-label">Your email address</span>
</div>

I have used contact form 7 and it gaves me this additional span. But I already found solution how to block this additional span. There is a filter that can remove this contact form 7 span. Here is the link.
