How do I hover over span to let a div appear? - html

Question

#hello{
font-size: 4em;
}
div.about{
display: none;
}
#hello:hover div.about {
display: block;
}
<pre id="hometext"><span id="hello">Hello!</span></pre>
<div class="about" id="about"><p>hello</p></div>
First of all, I am new to stackoverflow. Secondly, I want to over a specific part of a paragraph, the span, and then let this div appear. But it doesnt seem to work..

Answer 1

You dont have to use javascript:
#hometext:hover + #about { display:none; }

Answer 2

I am not quite sure if this is what you asked for, but you can utilize the span element's onmouseover and onmouseout attributes.
With a little bit of javascript, you can achieve what I think you want to do:
function hideDiv() {
document.getElementById("divToHide").style.visibility = 'hidden';
}
function showDiv() {
document.getElementById("divToHide").style.visibility = 'visible';
}
#divToHide {
height: 100px;
width: 100px;
background: red;
}
#hoverMe {
cursor: pointer;
}
<div id="divToHide">
</div>
<br />
<p>
This is a paragraph. If you hover <span id="hoverMe" onmouseover="hideDiv()" onmouseout="showDiv()">here</span>, it will hide the red box.
</p>

Answer 3

I think you need some javascript there:
function showOtherDiv() {
document.getElementById("about").style.display = "block";
}
function hideOtherDiv() {
document.getElementById("about").style.display = "none";
}
#hello {
font-size: 4em;
}
div.about {
display: none;
}
#hello:hover div.about {
display: block;
}
<pre id="hometext">
<span id="hello" onmouseover="showOtherDiv()" onmouseout="hideOtherDiv()">Hello!</span>
</pre>
<div class="about" id="about">
<p>hello</p>
</div>
