A floating label input — where the field's label starts inside the input box, then smoothly animates up and shrinks once the field is focused or filled — saves vertical space while keeping the label always visible, unlike a plain placeholder that disappears once typing starts.
Customize the accent color, click into the preview input to see the label smoothly float upward, then copy the complete HTML and CSS needed to add the same floating label behavior to your own form inputs.
This technique uses the CSS `:focus` and `:not(:placeholder-shown)` pseudo-classes to detect when the label should float, meaning it requires no JavaScript at all — the animation triggers purely through CSS state selectors.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
Frequently asked questions
Does this require JavaScript to work?
No, this floating label effect is achieved purely through CSS using the :focus and :not(:placeholder-shown) pseudo-classes — no JavaScript is needed.
Why does the input need a placeholder attribute even though it's not visually shown as a placeholder?
The CSS technique relies on the :placeholder-shown pseudo-class to detect whether the field is empty, so an (even blank) placeholder attribute is required for the detection logic to work correctly.
