Center an SVG inside a DIV

Question

I have a div with an SVG inside it:

.svg * {
  display: block;
  margin: 0 auto;
  fill: red;
}

<div class="foo ball design">
  <svg class="svg pen" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="48px" height="48px" viewBox="0 0 48 48">

    </g>
  </svg>
</div>

I want to center the SVG inside the div. Is this not the right way to center an SVG when it is in its "html-like" code form? (Not sure what it's called.)

I know I am targeting my sass correctly as fill: red is working.

Please Advise and let me know if you need to see more of my code, thanks for your time!

Answer 1

• Make the div position:relative and the svg position:absolute
• For the svg give it top:(calc 50% - 24px) and left:(50% - 24px)

That's 50% of containing div's height minus half the height of svg and 50% of containing div's width minus half the width of svg. A position:absolute element (i.e. svg) boundaries are it's position:relative parent's (i.e. .foo) borders.

.svg {
  display: block;
  margin: 0 auto;
  position: absolute;
  top: calc(50% - 24px);
  left: calc(50% - 24px);
}
.foo {
  height: 150px;
  width: 150px;
  position: relative;
  border-radius: 50%;
  border: 20px solid brown;
  background: black;
}
