How to find center of native cursor and align the custom cursor to it?












1















I have created a custom cursor using two div elements, both of them are circles. First one is the main cursor and other one is its follower. They use jQuery to track mouse coordinates. My problem is, when the cursor is not moving I want to make both look like concentric circles(both circle have same center) but they are not at center. I have tried it using (e.PageX -(offset - radius of circle)) but it doesn't return any value.
I am not able to explain this properly sorry new here, I have linked the codepen below:



$(document).mousemove(function(e){
$('#cursor').css({
"left" : (e.pageX + 'px'),
"top" : (e.pageY + 'px')
});
$('#cursorFollow').css({
"left" : (e.pageX + 'px'),
"top" : (e.pageY + 'px')
});
});

  • Can you show what you tried? It works for me when I change the positions in the codepen to, e.g. ((e.pageX-6) + 'px').

  • @MrLister Yes it works when you subtract pixels but I was looking for a more perfect way. I tried subtracting the (offset - radius) from the e.Page coordinates each. But it doesn't return any values, it returns NaN. Anyways got the solution below, Thanks for contributing

The thing is you are getting the left and top of the cursor's point to set the position of both circle and one is smaller than other so they are being painted from that exact position



If you want to center the circle to the pointer of the cursor use transform: translate(-50%, -50%); in both element it will move the circles half its size in both directions (center)






$(document).mousemove(function(e){
$('#cursor').css({
"left" : (e.pageX + 'px'),
"top" : (e.pageY + 'px')
});
$('#cursorFollow').css({
"left" : (e.pageX + 'px'),
"top" : (e.pageY + 'px')
});
});

*{
/* cursor:none; */
}
body{
height: 300vh;
}
.cursor{
position: absolute;
height: 8px;
width: 8px;
border-radius: 50%;
background-color: #000;
transform: translate(-50%, -50%); //new
}
.cursor-follower{
position: absolute;
height: 20px;
width: 20px;
border-radius: 50%;
opacity: 0.4;
border-radius: 50%;
background-color: #000;
transition: 0.2s ease-out;
pointer-events: none;

  • @Ryuzaki98 it is laggy because the transition: 0.2s ease-out; that makes it take 0.2 seconds to reach the cursor and the ease-out make it fast/abrupt at the beginning, slow at the end, check this css-tricks.com/ease-out-in-ease-in-out to a better understand in transition-timing-function Can you please upvote the answer too?
