Bootstrap Design Generator

A single-file Bootstrap 5 website template generator that produces complete, randomized SaaS landing pages with 201 million+ unique visual combinations. Every click generates a fully functional, responsive, dark-mode-ready website you can download as a standalone HTML file -- including video background heroes, privacy/terms modals, cookie consent, and scroll animations.

Download or use on https://pietercooreman.github.io/Bootstrap-Design-Generator/

Next: Upload any generated template to any AI-chatbot and ask to replace/add/remove texts and images.


Quick Start

  1. Open index.html in any modern browser
  2. Click the generate button (or wait -- it auto-generates on load)
  3. Click the download button to save the template as a standalone .html file

No build tools, no dependencies, no server required.

Selection Styling ::selection uses palette primary color
Gradient Border Popular pricing card uses background-clip: padding-box, border-box trick
Parallax Full-bg-glass hero uses background-attachment: fixed
Fluid Typography clamp() on hero headings for responsive scaling without breakpoints
Spring Easing Buttons use cubic-bezier(.34, 1.56, .64, 1) for springy overshoot
Smooth Scrolling scroll-behavior: smooth on <html>
Scroll Margin scroll-margin-top: 80px prevents anchors from hiding behind sticky nav
Button Glow Primary buttons have palette-colored box-shadow that intensifies on hover
Transition Orchestration All theme-sensitive properties transition on dark/light mode switch (background, color, border-color)
Video Cover Background HTML5 <video> with object-fit: cover fills hero viewport; fallback to static background image

Responsive Design

  • Navbar collapse at <lg breakpoint with Bootstrap hamburger toggler
  • Fluid typography via clamp() on all hero headings (5 different clamp values)
  • Responsive grid with col-6 / col-md-* / col-lg-* for mobile-first layouts
  • Glass float cards hidden on mobile (display: none at <768px)
  • Reduced heading sizes at <768px (h1: 2rem, h2: 1.6rem)
  • Flex wrap on button groups and CTA sections for mobile stacking
  • Cookie toast width adapts: max-width: 540px; width: calc(100% - 2rem)
  • Viewport meta tag on all generated pages
  • Overflow protection -- overflow-x: clip on <html> and overflow: hidden on hero sections prevent horizontal scrollbar from decorative elements

Accessibility

  • prefers-reduced-motion media query disables all animations and transitions
  • aria-label on all close buttons
  • aria-labelledby connecting modal titles to their headers
  • aria-hidden="true" on modals
  • tabindex="0" on <body> (required for ScrollSpy)
  • lang="en" on <html>
  • alt attributes on all images (hero, cards, avatars)
  • title attribute on dark mode toggle
  • Semantic HTML throughout (<nav>, <section>, <footer>, <label>)
  • <iframe title="Preview"> on generator preview

  • Terms of Service -- 7-section modal: Acceptance, Registration, Acceptable Use, Intellectual Property, Payment & Billing, Limitation of Liability, Governing Law (Delaware)
  • Cookie Consent -- Bottom toast with Accept/Decline + link to Privacy Policy
  • Dynamic dates -- Policy dates and copyright year use new Date()
  • Dynamic brand references -- All legal text references the generated brand name

Combination Math

The generator randomly selects from independent pools for each design dimension:

12 palettes x 10 fonts x 28 brands x 6 heroes x 5 nav styles
x 5 button variants x 5 card styles x 4 grids x 3 feature layouts
x 3 testimonial layouts = 201,600,000 base combinations

With conditional sections (8 independent toggles including announcement bar), data pool selections, video background randomization (20% chance), and section ordering randomization, the effective number of distinct templates is orders of magnitude higher.


Tech Stack

Layer Technology
Framework Bootstrap 5.3.3 (CSS + JS Bundle with Popper)
Icons Bootstrap Icons 1.11.3
Fonts Google Fonts (10 families, dynamically loaded)
Animations AOS 2.3.4 (Animate On Scroll)
Images Unsplash (97 unique verified photos + 12 avatars)
Video Mixkit (21 unique free stock MP4s via CDN, no API key required)
Generator Vanilla JavaScript (single file, no build step)
Output Self-contained HTML files (no external dependencies beyond CDN links)

Generator UI

The generator itself has a minimal dark-themed sidebar interface:

  • Generate button -- Produces a new randomized template (auto-runs on page load)
  • Download button -- Saves the current template as bootstrap-template.html
  • Mode toggle -- Three-state cycle: Auto / Force Dark / Force Light
  • Generation counter -- Tracks templates generated in the current session
  • Browser chrome -- Preview frame with URL bar showing palette, layout, and mode info

Browser Support

Generated templates work in all modern browsers that support:

  • CSS Custom Properties
  • backdrop-filter (glassmorphism)
  • CSS clamp()
  • scroll-behavior: smooth
  • HTML5 <video> with autoplay + muted (for video hero backgrounds)
  • Bootstrap 5.3.3 requirements

Graceful degradation for prefers-reduced-motion and browsers without backdrop-filter support. Video heroes fall back to a static background image if video loading fails. Works from file:// origins (local HTML files) without restrictions.
