How do I centre an svg path in an svg circle?

I have an svg of the GitHub logo (taken from Simple Icons).

I would like to centre this svg in a circle so it looks something like this:

enter image description here

I've tried taking the path from the svg and creating another svg with that path and a circle, like:

svg {
  padding: 5px;
  fill: none;
  stroke: black;
  stroke-width: 1px;
  stroke-linejoin: round;
}

svg:hover {
  stroke: red;
}
<svg height="90" width="90">
  <circle cx="48%" cy="48%" r="48%" />
  <path d="M12 .297c-6.63 0-12 5.373-12 12 0 5.303 3.438 9.8 8.205 11.385.6.113.82-.258.82-.577 0-.285-.01-1.04-.015-2.04-3.338.724-4.042-1.61-4.042-1.61C4.422 18.07 3.633 17.7 3.633 17.7c-1.087-.744.084-.729.084-.729 1.205.084 1.838 1.236 1.838 1.236 1.07 1.835 2.809 1.305 3.495.998.108-.776.417-1.305.76-1.605-2.665-.3-5.466-1.332-5.466-5.93 0-1.31.465-2.38 1.235-3.22-.135-.303-.54-1.523.105-3.176 0 0 1.005-.322 3.3 1.23.96-.267 1.98-.399 3-.405 1.02.006 2.04.138 3 .405 2.28-1.552 3.285-1.23 3.285-1.23.645 1.653.24 2.873.12 3.176.765.84 1.23 1.91 1.23 3.22 0 4.61-2.805 5.625-5.475 5.92.42.36.81 1.096.81 2.22 0 1.606-.015 2.896-.015 3.286 0 .315.21.69.825.57C20.565 22.092 24 17.592 24 12.297c0-6.627-5.373-12-12-12"/>

But I don't know how to centre the path in the circle, how would I do that?

Solution

  • The moment you start with translate
    you will continue to stack <g> groups and translates like empty sushi plates at a party of 10

    Instead, learn to edit MDN: SVG paths

    Tool of choice: SVG Path Editor https://yqnn.github.io/svg-path-editor/

    • Copy/paste d-path
    • reduced presicion to 0 (for explanation purposes, but its always good to lower precision.
      there is no point in stuffing 10000 svg "pixels" into 1 screenpixel with N.1234 precision)

    The path is:

    M12 0c-7 0-12 5-12 12c0 5 3 10 8 11c1 0 1 0 1-1c0 0 0-1 0-2c-3 1-4-2-4-2C4 18 4 18 4 18
c-1-1 0-1 0-1c1 0 2 1 2 1c1 2 3 1 4 1c0-1 0-1 1-2c-3 0-6-1-6-6c0-1 1-2 1-3c0 0-1-2 0-3
c0 0 1 0 3 1c1 0 2 0 3 0c1 0 2 0 3 0c2-2 3-1 3-1c1 2 0 3 0 3c1 1 1 2 1 3c0 5-3 6-6 6
c0 0 1 1 1 2c0 2 0 3 0 3c0 0 0 1 1 1C21 22 24 18 24 12c0-7-5-12-12-12

    • Learn SVG: M and m are moves C and c are curves

    • capital M and C are absolute positioned points, we don't want those when we alter the path, because they would always stay at the absolute position

    • Convert to relative in the path editor

    The path is:

    m12 0c-7 0-12 5-12 12c0 5 3 10 8 11c1 0 1 0 1-1c0 0 0-1 0-2c-3 1-4-2-4-2c-1 0-1 0-1 0
c-1-1 0-1 0-1c1 0 2 1 2 1c1 2 3 1 4 1c0-1 0-1 1-2c-3 0-6-1-6-6c0-1 1-2 1-3c0 0-1-2 0-3
c0 0 1 0 3 1c1 0 2 0 3 0c1 0 2 0 3 0c2-2 3-1 3-1c1 2 0 3 0 3c1 1 1 2 1 3c0 5-3 6-6 6
c0 0 1 1 1 2c0 2 0 3 0 3c0 0 0 1 1 1c6-1 9-5 9-11c0-7-5-12-12-12

    • That first m12 0 is the start DRAWING position

    • In the editor we see:

      • the top-left is 0,0
      • the (square) image is 24 units wide
        (SVG is a vector format, they are not pixels)

    • to add space for a circle the image needs to be moved 6 units right and 6 units down

    • That changes the viewBox="0 0 24 24" to: viewBox="0 0 30 30"

      • A viewBox="0 0 W H" is the most comfortable for your future SVG adventures.
      • A viewBox="-15 -15 15 15" is great when you do a lot of drawing around a (0,0) center point.

    • Now instead of using transform="translate(x y)",
      you change the d-path start position from M12 0 to: M15 3

      • new x = x + 6/2 = 12 + 3 = 15

      • new y = y + 6/2 = 0 + 3 = 3

      • since it is the first path move, it doesn't matter if its m15 3 or M15 3

      • add a temp style pink to always see the viewBox size

    <svg height="90" width="90" viewBox="0 0 30 30" style="background:pink">
  <circle r="48%" cx="50%" cy="50%" fill="none" stroke-width="1" stroke="red" />
  <path d="M15 3c-7 0-12 5-12 12c0 5 3 10 8 11c1 0 1 0 1-1c0 0 0-1 0-2c-3 1-4-2-4-2c-1 0-1 0-1 0
c-1-1 0-1 0-1c1 0 2 1 2 1c1 2 3 1 4 1c0-1 0-1 1-2c-3 0-6-1-6-6c0-1 1-2 1-3c0 0-1-2 0-3
c0 0 1 0 3 1c1 0 2 0 3 0c1 0 2 0 3 0c2-2 3-1 3-1c1 2 0 3 0 3c1 1 1 2 1 3c0 5-3 6-6 6
c0 0 1 1 1 2c0 2 0 3 0 3c0 0 0 1 1 1c6-1 9-5 9-11c0-7-5-12-12-12"/>
</svg>

    End result:
