UI Shape Lab.
Toggle the switches to explore layout mechanics.
1. CSS Polygons
Using clip-path: polygon(). SURGICAL FIX: We let the native rounded-xl sit underneath the shape without toggling it off. This eliminates the nasty corner flashing you saw on close!
A. The Cyber Notch
B. The Diagonal Reveal
C. The Chat Bubble
D. Banner Ribbon
E. Sci-Fi Octagon
F. Parallelogram
G. The Cross Cutout
2. Inline SVGs & Shadows
CSS polygons can't do curves easily. For organic shapes, we define paths in a hidden <svg> block at the top of the file using clipPathUnits="objectBoundingBox" so they scale responsively from 0 to 1.
A. Folder Tab
System Files
B. Ticket Stub
C. Liquid Drip
Organic Drop
D. Cloud Header
Bubbly Top Edge
E. Sine Wave
Smooth Base
F. Zig-Zag Edge
Receipt Teeth
G. Arch Notch
Sweeping Arch Cutout
3. Mask Images
Unlike clip paths which use coordinate boundaries, mask-image acts like a physical stencil overlay. You can use external SVG files, gradient fades, or repeating patterns. Black pixels equal 100% visible; transparent pixels equal hidden.
A. External SVG Mask
B. The Themed Icon
C. Gradient Opacity Mask
This text block will smoothly fade into transparency at the bottom when toggled. Incredibly useful for UI elements indicating there is more content to scroll down to.
D. Halftone Dot Pattern
E. Repeating Stripes
F. Barcode Stencil
G. Vignette Fade
4. CSS Hover Morphing
SURGICAL FIX: Stripped rounded-xl off these elements completely so they maintain their sharp, strict geometric profiles during the morph!
5. View Transitions API
Instead of animating CSS properties, the browser natively screenshots the active DOM elements, tracks where they move to, and interpolates their size, position, and clipping instantly.
A. Grid List to Modal
B. Thumbnail to Lightbox
C. Toast to Inbox
D. FAB to Bottom Sheet
E. Dynamic Sorting (Click to top)
- Project Alpha
- Project Beta
- Project Gamma
F. Search Bar to Overlay
G. Mini Player to Fullscreen
H. List to Hero Header

The Future of UI
By combining standard CSS layout with native hardware rendering techniques, we can create experiences on the web that are indistinguishable from downloaded mobile applications.
6. Text Clipping & Flow
Typography doesn't have to be boring. We can clip backgrounds inside text or force text to wrap organically around circular shapes instead of standard square boundaries.
A. Image Background Clip
STUNNING
B. Gradient Text Clip
NEON GLOW
C. Organic Text Wrapping
shape-outside property allows content to flow dynamically along a specified geometry, creating an editorial, magazine-like aesthetic on the web that feels highly polished and completely breaks the traditional rectangular grid system.
D. Outline Text Stroke
HOLLOW
E. Diagonal Text Wrap
shape-outside property, this paragraph text is forced to wrap along a harsh diagonal slant. Notice how the text cascades perfectly down the hypotenuse of the triangle! This allows for incredibly dynamic layouts without complex grid tricks.
F. Blend Mode Knockout
