Which parts became utilities, which stayed CSS, and why.
- The
@media (max-width:768px)block disappears entirely. One column andhiddenon the aside are the base state;md:adds the split. Mobile-first is not a style preference here — it deletes code. focus-visible:ring-4 focus-visible:ring-tlf01-ringreplaces a hand-writtenbox-shadow:0 0 0 4px oklch(...), and the ring colour becomes a token every other demo element can reuse — the submit button's outline reads the same one.text-[27px]/[1.28]carries size and line-height in one utility, which is the single biggest readability win of the port on a marketing panel like this.- UI change from the CSS original: type moved from
'Segoe UI'to Plus Jakarta Sans, the muted body colour went from#69708atooklch(0.5 0.03 270)(4.6:1 on the stage, up from 4.1:1), and the testimonial caption from#aeb7ddtooklch(0.79 0.04 270)so it clears 4.5:1 on the deep brand navy.

Demo: Tailwind Split-Screen Brand Hero Login Form
Source: https://codefronts.com/components/tailwind-css-login-forms/tailwind-split-screen-brand-hero-login-form/
The high-conversion SaaS classic: a 50/50 desktop split with an isolated minimal form on one side and a branded panel — headline, testimonial, gradient mesh — on the other. The port's win is the collapse: grid-cols-1 md:grid-cols-[1.05fr_1fr] replaces a media query with a mobile-first default, so the single-column case is what the markup says by default rather than an override at the bottom of a stylesheet.

Demo: Tailwind Split-Screen Brand Hero Login Form
Source: https://codefronts.com/components/tailwind-css-login-forms/tailwind-split-screen-brand-hero-login-form/
The high-conversion SaaS classic: a 50/50 desktop split with an isolated minimal form on one side and a branded panel — headline, testimonial, gradient mesh — on the other. The port's win is the collapse: grid-cols-1 md:grid-cols-[1.05fr_1fr] replaces a media query with a mobile-first default, so the single-column case is what the markup says by default rather than an override at the bottom of a stylesheet.

```How this works
The media query becomes a breakpoint prefix. The CSS version ends with @media (max-width:768px){ grid-template-columns:1fr; .brand{display:none} } — the mobile case as an afterthought. Tailwind inverts it: one column and a hidden aside are the base, md: adds the split. The narrow layout is now unmissable in the markup instead of buried 40 lines away.
Each cell still owns its padding. p-12 on the brand body and p-9 sm:p-12 on the form panel, never on the grid itself — so the collapse keeps clean edges, exactly as the original insisted.
The form is unchanged where it matters. Real <form>, wrapping <label>s, type=email / type=password with autocomplete: Tailwind moves style, not semantics, and password managers see the same DOM they did before.
Make it yours
- Split ratio: edit the one arbitrary value,
md:grid-cols-[1.05fr_1fr]. - Put the brand on the right with
md:order-2on the aside — nodirectionhacks. - Retheme from
--color-tlf01-acc: button, links, avatar and focus halo all read it. - Drop a real logo or testimonial avatar in — the flex column already reserves the space.
Gotchas — read before shipping
- Pad the cells, not the grid container, or the mobile collapse inherits a double gutter.
- Keep the panel a real
<form>; a<div>of inputs silently disables autofill and the Enter key. hidden md:flexand notmd:block— the aside is a flex parent, andhiddenresetsdisplay, so the responsive utility has to restate the layout mode it wants.
