## Where to use it

A good match for copy buttons with a bit of personality, like the discount code in an online shop's promo banner or the coupon at the end of a newsletter. The two colors come from your palette, so the tooltip feels branded instead of the usual black label. This CSS tooltip opens below the button.

Pick two colors the text stays readable on, because the message sits right on top of them. If your brand colors are pale, darken them a notch. And keep the message short: the halves look best closing around two or three words.

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 “Split tooltip” block (Tooltips) from AIMRAN Library to my project.

## What it is
Two color halves slide in from each side and meet in the middle, forming the tooltip below the button.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Copied to clipboard"

## 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.
