How to add extra outer space to inline svg?

I have an inline svg with transparent fill and a dark stroke. When it's hoverd, I want to fill it with the dark color.
The problem is that when I increase the stroke-width to make the stoke more visible, the stroke goes out the width box of the element like in the screenshot below.
So how to give the svg element an extra space for the stroke to grow?

enter image description here

svg {
  width: 10rem;
  fill: transparent;
  stroke: #222;
  stroke-width: 30;
}

svg:hover {
  fill: #222;
}
<svg 
  viewBox="0 -28 512.00002 512"

Solution

  • Adjust the viewBox attribute:

    viewBox="-25 -53 562.00002 562"

    Adds space for a 25px margin.

    Note that you have to decrease the top/left coordinates by 25 and increase the bottom/right coordinates by double the amount as your width/height must cater for 2 times the margin width.

    svg {
  width: 10rem;
  fill: transparent;
  stroke: #222;
  stroke-width: 30;
}

svg:hover {
  fill: #222;
}
    <svg
