(First run the code) In above code, I want to make the .border circle animation (when you run code and enter the mouse into the page, you can see the border on the top left) around the .menu__item circles after click. when the user clicked on the buttons I want to make that border with animation somehow around the menu buttons but I do not know how to do this responsively.

CodePudding user response：

You could create a reusable svg <symbol> and add it to your icon elements like so:

<!-- circle symbol -->
<svg  viewBox="0 0 24 24" aria-hidden="true">
  <symbol id="circle-ani" overflow="visible">
    <circle fill="none" cx="50%" cy="50%" r="70%">
  </symbol>
</svg>

Modified icon:

  <button  style="--bgColorItem: #ff8c00;">
    <svg  viewBox="0 0 24 24">
      <path d="M3.8,6.6h16.4" />
      <path d="M20.2,12.1H3.8" />
      <path d="M3.8,17.5h16.4" />
      <use  href="#circle-ani" />
    </svg>
  </button>

Additional css

You will need to make sure, the overflow is visible, since the circle element is exceeding the boundaries of your icon's viewBox:

.svgHidden{
  position:absolute;
  width:0;
  height:0;
  overflow:hidden;
}

.menu__item svg{
  overflow:visible
}

.circle{
  stroke-width:0
}
.menu__item.active
.circle{
  stroke-width:1.5
}
