How do you fake 3D depth with just text-shadow?

The effect stacks many text-shadow layers, each offset by one more pixel along the chosen angle than the last (using cos/sin of the angle to get consistent x/y steps), so the layers build up into a solid-looking wall of color behind the front-facing text — like a staircase of shadows.

How many layers (depth) should I use?

Somewhere between 15 and 30 layers looks solid for most font sizes without visible gaps; fewer layers (5-10) reads as a simpler drop-shadow-with-thickness look, while pushing past 40-50 mostly adds rendering cost without a visible difference since the layers already fully overlap.

Does a large depth value hurt performance?

Each layer is one more shadow the browser has to paint, so a very high depth on a lot of animated or frequently-repainted text can be noticeably slower — for static headlines it's fine, but keep depth modest if the text itself is animating.

Can I change the direction of the extrusion?

Yes — the angle control changes which way the 'depth' falls (straight down, down-right, etc.), the same way you'd rotate a 3D object's light and shadow; 45 degrees down-right is the classic retro-game look.

Is this generated locally?

Yes — the shadow stack is computed with client-side JavaScript and nothing is uploaded or stored.

How to build 3D extruded text

1
Type your headline text.
2
Pick a preset or set the extrusion angle and depth (how many layers thick it looks).
3
Choose the extrusion color and the front face color.
4
Increase depth for a chunkier block look, or keep it shallow for a subtle lift.
5
Copy the generated text-shadow CSS and HTML.
