How to Build a Split-Screen Sign-In Layout with an Overlay Card Using Tailwind CSS and Alpine.js
In this tutorial, we’re building a clean, modern split-screen sign-in layout using Tailwind CSS — with a tiny Alpine.js enhancement to toggle password visibility. The left side contains the form; the right side features a full-height image with a floating overlay card positioned on top using position: absolute.
It’s a minimal, polished pattern you can drop straight into any SaaS, marketing site, or dashboard onboarding flow.
What you’ll learn:
- How to structure a responsive split-screen layout that stacks on mobile and splits on large screens
- How to design polished form fields with left-aligned icons and smooth focus states
- How to implement a password field with a show/hide toggle using Alpine.js
- How to build a right-side image panel and position a floating absolute overlay card above it
- How to apply small but important accessibility enhancements (
sr-only, labels, aria attributes)
