<label> Tag — HTML Technical Interview Questions & Answers

A caption bound to a specific form control.

<label> Tag

  • A caption bound to a specific form control.
  • <label> is caption bound to an input. HTML uses this tag so the browser (and screen readers) know what the piece is, not only how it looks.
  • Board: <label for="n">Name</label> Put it in body. Check it in the browser. Attributes go on the opening tag.
  • Trap: placeholder instead of label. 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.

Technical Interview Tip: <label>: caption bound to an input. Example: <label for="n">Name</label>
