I need get hover effect in a div from the cursor position.
I have this html and css
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
border-radius: 100px;
}
.s {
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
margin: 75px 0px 0px 75px;
transition: width 1s, height 1s, margin 1s;
}
.s:hover {
width: 100px;
height: 100px;
background-color: black;
margin: 50px 0px 0px 50px;
}
<div class="f">
<div class="s"></div>
</div>
And I need something like this:
I'm open to js or jquery solutions.
I have a jquery solution:
$("div.f").mousemove(function(e) {
$('div.s').css({
left: e.clientX - 28,
top: e.clientY - 24
});
});
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
border-radius: 100px;
/* comment or remove the overflow if necessary */
overflow: hidden;
}
.s {
position: absolute;
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="f">
<div class="s"></div>
</div>
But i need the circle make the over animation like first snippet.
Original question here
To change position of inner circle you can use pageX and pageY on mousemove. To change size of inner circle you can create one class that will scale div and toggle that class on hover over .f.
var s = $('.s')
var f = $('.f')
var oTop = f.offset().top + (s.height() / 2);
var oLeft = f.offset().left + (s.width() / 2);
f.hover(function() {
s.toggleClass('change')
})
f.mousemove(function(e) {
var x = e.pageY - oTop
var y = e.pageX - oLeft
s.css({
top: x + 'px',
left: y + 'px'
})
})
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
overflow: hidden;
border-radius: 100px;
}
.s {
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
position: absolute;
pointer-events: none;
opacity: 0;
transition: transform 0.5s linear, opacity 0.3s linear;
}
.change {
transform: scale(2);
opacity: 1;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="f">
<div class="s"></div>
</div>
Here is a jQuery solution.
$("div.f").mousemove(function(e) {
$('div.s').css({
left: e.clientX - 28,
top: e.clientY - 24
});
});
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
border-radius: 100px;
/* comment or remove the overflow if necessary */
overflow: hidden;
}
.s {
position: absolute;
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="f">
<div class="s"></div>
</div>
$('.f').on('mousemove', function(e){
var par = $(this);
if((e.pageX <= par.width() && e.pageX >= 0) && e.pageY <= par.height() && e.pageY >= 0){
$('.s').css({
position: 'relative',
left: e.pageX - (par.width() / 2),
top: e.pageY - (par.height() / 2)
});
} else {
$('.s').css({
position: 'initial'
});
}
});
.f {
width: 200px;
height: 200px;
background-color: grey;
position: fixed;
border-radius: 100px;
}
.s {
width: 50px;
height: 50px;
background-color: black;
border-radius: 100px;
margin: 75px 0px 0px 75px;
transition: width 1s, height 1s, margin 1s;
}
.s:hover {
width: 100px;
height: 100px;
background-color: black;
margin: 50px 0px 0px 50px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="f">
<div class="s"></div>
</div>
