<svg> Tag

  • Embeds scalable vector graphics.
  • <svg> is the <svg> HTML element. HTML uses this tag so the browser (and screen readers) know what the piece is, not only how it looks.
  • Board: <svg>…</svg> Put it in body. Check it in the browser. Attributes go on the opening tag.
  • Trap: wrong nesting or missing a required attribute. CSS can still style it — don’t pick a tag only because of default italics.
  • Interview: name the tag, one attribute if it has a famous one (href, src, alt, for, type), one mistake.
