Circle around div when hover

I have a sun shape div. I just want to show a border when hover it with transparent gap between hover border and object.

在此输入图像描述

First I tried with box shadow but cant make white gap. It requires solid color, then I tried with this way. But the gap is not appearing.

Here is my code.

  .sun-quote-pages{ border-radius: 50%; background-color: #f4953b; width: 4.1em; height: 4.1em; border: 2px solid transparent; transition: transform 0.5s ease, background 0.5s ease, box-shadow 0.5s ease; } .sun-quote-pages:hover { transform: scale(1.3); border: 2px solid #f4953b; margin: 2px; padding: 2px; } .wrapper{ margin-left:150px; margin-top:50px; } 
  <div class="wrapper"> <div class="sun-quote-pages"> </div> </div> 

What am I missing here?

The solution is 'background-clip' found here:

https://css-tricks.com/transparent-borders-with-background-clip/

With it you can prevent the background color from flowing under the border and padding. It is widely supported:

https://caniuse.com/#search=background-clip

so your CSS would become:

.sun-quote-pages{
  border-radius: 50%;
    background-color: #f4953b;
    width: 4.1em;
    height: 4.1em;
    padding: 2px; 
    border: 2px solid transparent;
    background-clip: content-box;
    transition: transform 0.5s ease, border 0.5s ease;
}

.sun-quote-pages:hover {
    border: 2px solid #f4953b;
    transform: scale(1.3);
}


.wrapper{
  margin-left:150px;
  margin-top:50px;
}

Or why not have a double border?

See: https://jsfiddle.net/auzjv4rp/13

 .sun-quote-pages:hover { transform: scale(1.3); } .sun-quote-pages:hover::after { border: 2px solid #f4953b; } .sun-quote-pages{ width: 4.1em; height: 4.1em; margin: 20px auto; border-style: ridge; border: 2px solid transparent; border-spacing:10px; border-radius: 50%; position:relative; background-color: #f4953b; transition: transform 0.5s ease, background 0.5s ease, box-shadow 0.5s ease; } .sun-quote-pages:after { content: ''; position: absolute; top: -10px; left: -10px; right: -10px; bottom: -10px; border: 2px solid transparent; border-radius: 50%; } .wrapper{ margin-left:150px; margin-top:50px; } 
  <div class="wrapper"> <div class="sun-quote-pages"> </div> </div> <style> 

Try This..

Try this

 .sun-quote-pages{ border-radius: 50%; background-color: #f4953b; width: 4.1em; height: 4.1em; border: 2px solid transparent; transition: transform 0.5s ease, background 0.5s ease, box-shadow 0.5s ease; position:relative; box-sizing: border-box; } .sun-quote-pages:hover { border: solid 2px #f4953b; padding: 5px; background-clip: content-box; /* support: IE9+ */ background-color: #f4953b; transform: scale(1.3); } .wrapper{ margin-left:150px; margin-top:50px; } 
 <div class="wrapper"> <div class="sun-quote-pages"> </div> </div>

You can implement like using :before property. Add following CSS and try:

.sun-quote-pages:before{
    content: "";
    position: absolute;
    top: -5px;
    right: -5px;
    bottom: -5px;
    left: -5px;  
    border-radius: 50%;
}

.sun-quote-pages:hover:before {
    border: 2px solid #f4953b;
}

See JSfiddle : https://jsfiddle.net/qsb6y0rc/75/

You can create the sun element with background-color , shadow and border with width: 0

<div class="sun"></div>

.sun {
    background-color: #f4953b;
    height: 80px;
    width: 80px;
    box-sizing: border-box;
    border-radius: 50%;
    box-shadow: 0 0 0 3px #f3f5f6 inset;
    border: solid 0 #f4953b;
    transition: border-width 0.3s linear;
}

Then on hover, just animate the border-width :

.sun:hover {
    border-width: 3px;
}

Here is a working demo :

You can use css pseudo selector :after , which size is bigger than the original element. Set this element transparent background and the same border color as the original element like this:

 body { background: gray; } .sun-quote-pages{ border-radius: 50%; background-color: #f4953b; width: 70px; height: 70px; transition: transform 0.5s ease, background 0.5s ease; } .sun-quote-pages::after { content: "\\00a0"; display: block; background: transparent; height: 80px; width: 80px; border-radius: 50%; border:2px solid #f4953b; opacity: 0; box-sizing: border-box; transition: opacity 0.5s ease 0.5s; transform: translate(-5px,-5px); } .sun-quote-pages:hover { transform: scale(1.3); } .sun-quote-pages:hover::after { opacity: 1; } .wrapper{ margin-left:150px; margin-top:50px; } 
 <div class="wrapper"> <div class="sun-quote-pages"> </div> </div> 

Here is an idea using radial-gradient

 .sun-quote-pages { border-radius: 50%; background: radial-gradient(circle at center,#f4953b 54%,transparent 56%,transparent 65%,#f4953b 66%); background-color: #f4953b; width: 4.1em; height: 4.1em; border: 2px solid transparent; transition: transform 0.5s ease, background 0.5s ease, box-shadow 0.5s ease; } .sun-quote-pages:hover { transform: scale(1.3); background-color:transparent; } .wrapper { margin-left: 150px; margin-top: 50px; } 
 <div class="wrapper"> <div class="sun-quote-pages"> </div> </div>
