Explanation
Option B is correct because the placeholder attribute displays hint text inside a form field (e.g., "Enter your email") that disappears once the user starts typing - it's a short description of the expected input, not a persisted value. Option A is wrong because tooltips are created with the title attribute, not placeholder. Option C is incorrect since CSS classes are assigned via the class attribute. Option D is a common mix-up - labels are created with the <label> element and its for attribute, which is a separate, accessible mechanism for describing a field.
Memory tip: Think of a placeholder as a "ghost" inside the input box - it shows you what belongs there, then vanishes when you take over. If it stuck around after you typed, it would be a value, not a placeholder.

Hiroshi T.Mar 23, 2026B is correct. The placeholder attribute displays hint text inside a form field that disappears when the user starts typing, giving a visual cue about the expected input, not a persisted default value like the value attribute provides. The HTML5 spec (section 4.10.18.5) distinguishes placeholder from label, tooltip (title), and CSS class (class), so the other options describe entirely different mechanisms.
Fatima Z.Mar 26, 2026Hiroshi nailed it, and here is the sticky hook to cement it: think PLACEHOLDER equals PHANTOM TEXT, it haunts the field until you type, while VALUE is the actual ghost that stays permanently, so the spec is really just saying a ghost is not a resident.
Carlos M.Apr 4, 2026B is right, placeholder shows hint text inside the input, not a real value.
Fatima Z.Apr 20, 2026B nails it, placeholder shows hint text that vanishes once you start typing.
Hiroshi T.Apr 21, 2026Fatima is right that the disappearing hint is the expected behavior, but keep in mind that some accessibility guidelines (WCAG 2.5.3 and the supporting techniques) recommend pairing the placeholder with a persistent visible label so users do not lose context mid-entry if they pause to verify what the field requires.
Brenda K.Apr 10, 2026I almost picked D because labels and placeholders both describe what goes in a field, but then I remembered that placeholder text sits inside the input box itself and disappears when you start typing, which is exactly what a default value does, so B is the one. Watch your clock on this one, it is a quick 20-second read and move on, do not let the wording on D pull you into a two-minute debate with yourself.
Carlos M.Apr 11, 2026Solid reasoning on B, but just to sharpen it, placeholder text and a default value are not quite the same thing, since placeholder disappears on focus or first keystroke while a default value sits there until you actively clear it, which is a distinction that shows up on accessibility questions too so worth keeping in the back of your head.
Samuel O.Apr 24, 2026B is right, though I'd call it hint text, not a default value since it vanishes on input.
Fatima Z.Apr 26, 2026Lock it in with PAID: Placeholder And Input Disappear, which is exactly why "hint" fits and "default" falls flat, since a true default sticks around until the user overwrites it.
