# Save button with floppy disk

> Type and an unsaved dot appears; save with the floppy or Ctrl+S and the metal shutter slides while the drive light blinks.

## Where to use it

Saving is one of the most repeated actions in any editor, and this block turns it into a small piece of nostalgia. The button is a 3.5 inch floppy drawn in CSS: on save the metal shutter slides, the disk dips as if entering a drive and a green light blinks. It suits note apps, settings panels and document editors.

Typing marks the file as unsaved with an amber dot, and Ctrl+S or Cmd+S saves from anywhere inside the block. Change the main color for the disk plastic and the secondary for the light, and keep the timestamp so people know when they last saved.

## Prompt for AI assistants

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “Save button with floppy disk” block (Microinteractions) from AIMRAN Library to my project.

## What it is
Type and an unsaved dot appears; save with the floppy or Ctrl+S and the metal shutter slides while the drive light blinks.

## Chosen settings
- Main color: #1d4ed8
- Secondary color: #22c55e
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Guardar"

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
