Works in Divi without touching code
Every download includes a ready-made Divi 5 section for each shader (packs also include one file with all five). Import it, change the words, save. Hand the page to a client and they edit it like any other section, while the shader keeps running behind it.
01
Import
In the Visual Builder, open Portability, choose Import and pick the .divi.json file.
02
Edit
Heading, text and button are normal Divi modules. Set height in Design > Spacing or Sizing.
03
Publish
Save. The animated background shows on the live page and in preview.
// Plan B Code module fallback. If the import doesn't work on your Divi version, paste code-module/<shader>.html into a Code module at the top of any section. Needs an Administrator account so WordPress keeps the script.
// Not on Divi? HTML drop-in. Upload one .js file, add <div class="shader-bg" data-shader="…"> and the background mounts behind its content. Works on any HTML site.
// 02 Overview
What it does
Slow violet ink smoke drifts through the void, with one small curl of chartreuse tucked into the upper-right corner. Visitors can drag to stir the fluid and click to release a burst. Soft forces, strong damping and long emitter paths keep the motion unhurried, and autonomous emitters keep the ink moving with no input.
Part of Shader Pack 1: Cyberpunk Neon.
What’s included
- Original standalone HTML page (
02-neon-ink.html) - HTML drop-in: one JavaScript file, a copy-paste snippet and a demo page
- Divi 5 section (JSON import via Portability) plus a manual Code module fallback
- README files with install steps and settings
- LICENSE.txt (Schimke Studios Shader License)
Formats
HTML: a JavaScript file that mounts the shader as a full-bleed background behind a container such as <div class="shader-bg" data-shader="neon-ink">.
Divi 5: a section layout (JSON, imported through Divi Portability) with the shader as the section background behind a heading, text and button.
Settings: colours, speed and intensity can be set with a data-config attribute or in the CONFIG object at the top of the code. README files document the install steps and settings for both formats.
Under the hood
A GPU stable-fluids solver written from scratch: vorticity confinement, midpoint semi-Lagrangian advection with damping, a warm-started Jacobi pressure solve and projection, on half-float ping-pong render targets, with relief lighting from the dye gradient. Plain WebGL2 with inline GLSL ES 3.00, no external libraries.
Settings: colours, speed, simResolution, dyeResolution, pressureIterations, curl, velocityDissipation, dyeDissipation, splatRadius, splatForce, neonChance, ambientEmitters, ambientStrength, neonAmount, shading, grain.
Performance and accessibility
- Resolution-capped for high-DPI screens; pauses when scrolled out of view or when the tab is hidden
- Respects
prefers-reduced-motion(slowed or frozen) - Shows a static CSS gradient if WebGL2 is unavailable
Browser support
Any current browser with WebGL2: Chrome, Edge, Firefox and Safari 15+, on desktop and mobile. Needs the EXT_color_buffer_float WebGL extension (supported by nearly all desktop and modern mobile GPUs).
// 03 Fallback chain
Safe to hand off
Plain WebGL2 with no external libraries. Every shader steps down on its own, so a client's visitors never get a broken section.
