CSS Tooltip (tooltip display even if display none) - html

Question

I try to make a tooltip (hide/unhide span) when a div is hovered.
I don't know where is the problem because the span is always visible and if i add display:none, all content will be hidden.
Thank you very much!
CSS:
.tooltip {
display:relative;
}
.tooltip span:before {
content:'';
display:none;
border-right: 8px solid #000000;
border-top: 8px solid transparent;
border-bottom: 8px solid transparent;
position:absolute;
z-index:8;
font-size:0;
line-height:0;
width:0;
height:0;
top: 30%;
left: 83%;
}
.tooltip span:after {
display:none;
position:absolute;
top:0%;
left:89%;
padding:5px 8px;
background: #000000;
color:#fff;
z-index:9;
font-size: 0.75em;
height:auto;
opacity: 0.8;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
white-space:nowrap;
word-wrap:normal;
}
.tooltip span:hover:before,
.tooltip span:hover:after {
display:block;
}
HTML:
<div class="tooltip">
<span>tooltip text</span>
<input type="button" class="button active" value = "HOVER ME" >
</div>

Answer 1

Start with something like the following:
.tooltip {
position: relative;
display: inline-block;
}
.tooltip span {
display: none;
position: absolute;
top: 30px;
border: 1px solid #ccc;
padding: 5px;
background: #eee;
}
.tooltip:hover span {
display: block;
}
<div class="tooltip">
<span>tooltip text</span>
<input type="button" class="button active" value = "HOVER ME" >
</div>
See this fork of your fiddle: https://jsfiddle.net/b60fcyu1/

If you're up for a JavaScript/jQuery solution, you can use mouseover and mouseout with hide() and show() element.
$(document).ready(function() {
$("input.button").mouseover(function() {
$('div span').hide();
});
$("input.button").mouseout(function() {
$('div span').show();
});
});
.tooltip {
display: relative;
}
.tooltip span:before {
content: '';
display: none;
border-right: 8px solid #000000;
border-top: 8px solid transparent;
border-bottom: 8px solid transparent;
position: absolute;
z-index: 8;
font-size: 0;
line-height: 0;
width: 0;
height: 0;
top: 30%;
left: 83%;
}
.tooltip span:after {
display: none;
position: absolute;
top: 0%;
left: 89%;
padding: 5px 8px;
background: #000000;
color: #fff;
z-index: 9;
font-size: 0.75em;
height: auto;
opacity: 0.8;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
white-space: nowrap;
word-wrap: normal;
}
.tooltip span:hover:before,
.tooltip span:hover:after {
display: block;
}
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>
<div class="tooltip">
<span>tooltip text</span>
<br>
<input type="button" class="button active" value="HOVER ME">
</div>

If you have constant values, you can do it like this. (for more effective with multiple rows)
.tooltip {
position: relative;
width: 300px;
height: 30px;
}
.tooltip span {
opacity: 0;
pointer-events: none;
transition: 0.3s;
width: 100%;
position: absolute;
background-color: rgba(0, 0, 0, 0.6);
color: #ffffff;
line-height: 30px;
bottom: 40px;
border-radius: 5px;
padding: 0 5px;
}
.tooltip span:after {
top: 100%;
left: 50%;
border: solid transparent;
content: " ";
height: 0;
width: 0;
position: absolute;
pointer-events: none;
border-color: rgba(0, 0, 0, 0);
border-top-color: rgba(0, 0, 0, 0.6);
border-width: 6px;
margin-left: -6px;
}
.tooltip:hover span {
opacity: 1;
pointer-events: inherit;
}
<p style="height:100px;">
<!-- for seperate -->
</p>
<div class="tooltip">
<span>tooltip text tooltip text tooltip text tooltip text tooltip text tooltip text tooltip text tooltip text</span>
<input type="button" class="button active" value="HOVER ME" style="width:100%;height:30px">
</div>
