Elevation-Based CSS Shadow Generator Specification
Overview
A high-performance, browser-based utility tool designed to help developers and UI designers generate precise, professional-grade CSS box-shadow values. The tool focuses on "elevation"—the visual layering of components—providing a live preview and easy-to-copy code snippets.
Technical Requirements & Constraints
- Architecture: Single-file HTML/CSS/JS (no external build tools).
- Storage: No
localStorage,sessionStorage, or cookies. State is managed via JS variables. - Compatibility: Sandboxed iframe compatible.
- Aesthetic: High-end SaaS light-mode design (clean, airy, professional).
- No Branding: Ensure all UI labels are generic and purely descriptive.
UI Layout
1. Header
- Clean, minimalist title: "Elevation Shadow Generator".
- A brief, helpful subtitle explaining the primary function.
2. Main Tool Area (Two-Column Grid)
- Left Column (Controls):
- Elevation Level: A range slider (0-24) mapped to standard UI elevation levels.
- Shadow Color: A color input allowing the user to change the shadow's base color (default:
#000000). - Opacity Slider: A slider to control shadow alpha (0.00 to 1.00).
- Blur Radius: A fine-tuning slider for the blur amount.
- Spread Radius: A fine-tuning slider for the spread amount.
- Right Column (Preview):
- A large, centered "Card" container that updates in real-time as controls are adjusted.
- A "Copy Code" button prominently displayed below the card.
3. Results Section
- A read-only
<textarea>containing the generated CSS code (e.g.,box-shadow: 0 10px 15px -3px rgba(0,0,0,0.1);). - A subtle "Copied!" toast notification that appears upon successful copy.

- Pure Vanilla JS: Handle all DOM updates through standard events (
input,change). - No Popups: Do not use
alert(). Create a customdivfor feedback messages. - Accessibility: Ensure high contrast ratios and keyboard navigation support for all inputs.
- Responsive: Use CSS Grid with
frunits. On mobile, stack columns vertically; on desktop, display side-by-side. - Clean Code: Use semantic HTML5 elements (
<header>,<main>,<section>,<aside>).

Frequently Asked Questions
Everything you need to know about using this application.
How do I use this elevation-based shadow generator?
To use this tool, simply adjust the elevation slider to select your desired depth level, typically ranging from 0 to 24dp. You can further customize the shadow color and opacity using the provided color picker and alpha slider to match your specific UI design requirements. Once the preview card reflects your desired appearance, click the 'Copy CSS' button to instantly copy the corresponding code to your clipboard. This makes it easy to paste high-quality, professional shadow effects directly into your stylesheet.
Are these CSS shadow snippets production-ready?
Yes, all generated CSS code is written in standard, production-ready format. The code utilizes the standard box-shadow property, which is supported by all modern web browsers and follows best practices for performance and visual consistency. By ensuring that these snippets work across browsers without vendor prefixes, you can integrate them into your web projects with confidence. We focus on clean, optimized output to keep your development workflow efficient.
Does this tool store my previous designs or settings?
This application operates entirely in-memory for security and performance. We do not use cookies, localStorage, or any other form of persistent storage to save your settings. Because this tool is designed to run within a sandboxed environment, your data is cleared whenever the application is refreshed. This ensures a clean, privacy-focused experience every time you load the tool.
Can I adjust the shadow blur and spread values?
Yes, the tool allows for granular control over the shadow properties. While the elevation presets follow standard design principles, you can manually override the blur radius and spread values to create custom depths and styles. Adjusting these parameters in real-time allows for immediate visual feedback. You can experiment with different combinations until you achieve the exact visual weight required for your user interface components.
