What is this?

SVG embeds scalable vector shapes directly in HTML — crisp at any zoom.

Why should you care?

MarkupVerse icons, logos, and chart overlays stay sharp on retina displays.

What happened?

Inline SVG is DOM — style with CSS.
viewBox handles scaling.
Use aria-hidden on decorative icons.

Practice next

Draw a rect + text logo.
Add a status circle.
Resize with CSS width only.
Animate the circle with CSS.
Swap fill for dark mode via currentColor.

Remember

Vector = scalable. Inline = styleable. Hide decorative SVG from SR.
