# Screw-on lens filters

> Screw glass filters onto the lens; they stack up and the image adds the effect of each one.

## Where to use it

Photographers stack polarisers, ND and warming filters on their lenses, and this control does the same with checkboxes. Each filter screws on as a knurled ring with a short spin, and the view through the glass combines nested CSS filters, so two or three can work together. Use it in photo editors, camera apps or lessons about optics.

Change the brass accent and the barrel colour with the colour controls, and edit the list to add a mist filter or a red filter for black and white. Replace the SVG view with your own photo when you ship it.

## 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 “Screw-on lens filters” block (Filters) from AIMRAN Library to my project.

## What it is
Screw glass filters onto the lens; they stack up and the image adds the effect of each one.

## Chosen settings
- Main color: #e8a33d
- Secondary color: #1b1d22
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Filtros de objetivo"

## 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.
