How can an icon be perfectly centered inside a shape?

An icon centered inside a shape must use inline SVG. Unicode text glyphs cause alignment problems. A hand-authored SVG path ensures perfect centering.

The rule

An icon centered inside a shape must use inline SVG.

Unicode text glyphs cause alignment problems. A hand-authored SVG path ensures perfect centering.

Use inline SVG for icons placed inside shapes like circles or squares. SVG allows precise control over the icon's position. Unicode text glyphs are not reliable for exact centering. Their position changes slightly with different fonts or browsers. Adjusting them with code like padding does not fix the problem permanently. A single SVG path, created by a designer, solves this issue for all situations.

A designer creates a user interface with a 'play' icon inside a circle. If the designer uses a Unicode play symbol (▶), the icon might look off-center on some screens. If the designer uses an inline SVG with a defined viewBox, the play icon will always appear perfectly centered within the circle.
