22 CSS Split Screen Layouts

Q: How do I make a split-screen layout responsive?

Every demo here uses CSS grid (e.g. grid-template-columns: 50% 50% ) and switches to a single column under 720px via @media (max-width: 720px) . The layout stacks vertically on mobile with the visual side first, then the text side. Watch out for fixed widths or absolute-positioned overlays — those break the stack; relative + flex/grid is more forgiving.

Q: Can I animate the split ratio?

Yes. Use CSS transitions on grid-template-columns with named percentages ( 30% 70% ↔ 50% 50% ) — that's how the Music App Toggle and Two Seasons demos shift live. Pure CSS via :has(:checked) on a hidden checkbox or radio input. No JavaScript needed.

FAQ

Frequently asked questions

What is a CSS split-screen layout?

A split-screen layout divides the page into two (or more) full-bleed regions side by side. Common uses: hero + visual, image + text storytelling, sign-in + brand, before/after compare, two-product reveal. Unlike sidebar layouts (which are persistent page chrome), split-screens are usually a single full-height section that drives one moment of the page.

Should the split be exactly 50/50?

Not always. 50/50 is the default for compare layouts (before/after, two-product reveal). 60/40 emphasizes one side as the hero and the other as supporting content. 70/30 works well when one side is a featured project and the other is metadata or an index. Pick based on which side is the subject and which is the support.

How do I make a split-screen layout responsive?

Every demo here uses CSS grid (e.g. grid-template-columns: 50% 50%) and switches to a single column under 720px via @media (max-width: 720px). The layout stacks vertically on mobile with the visual side first, then the text side. Watch out for fixed widths or absolute-positioned overlays — those break the stack; relative + flex/grid is more forgiving.

Can I animate the split ratio?

Yes. Use CSS transitions on grid-template-columns with named percentages (30% 70% ↔ 50% 50%) — that's how the Music App Toggle and Two Seasons demos shift live. Pure CSS via :has(:checked) on a hidden checkbox or radio input. No JavaScript needed.

What's the difference between a split-screen and a sidebar layout?

A sidebar is persistent page chrome — it stays visible across all pages of the app, contains navigation, and the main content scrolls beside it. A split-screen is a single full-height section that's typically used once per page (hero, sign-in, comparison) and doesn't persist as the user navigates. They use similar CSS techniques (grid, flex, clip-path) but serve completely different jobs. If you need to tell a story across a sequence of moments instead of contrasting two at once, look at the [CSS timeline layouts](/layouts/css-timelines/).

CSS Center a Div

The complete guide to centering a div in CSS in 2026 — covering all 5 production techniques with live interactive demos. Flexbox (the modern default, works for 95% of cases): <code>display: flex; align-items: center; justify-content: center</code> on the parent. CSS Grid (one-line shorthand): <code>display: grid; place-items: center</code>. Absolute positioning + transform (for overlays and modals): <code>position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%)</code>. Margin auto (for block elements with a known width): <code>margin: 0 auto</code> (horizontal only) or <code>margin: auto</code> with <code>position: absolute</code> + <code>inset: 0</code> (both axes). All methods side-by-side comparison — see every technique render the same content with visible axis crosshairs so you can see exactly where each method lands the element. All 5 demos are 100% pure CSS, MIT-licensed, copy-paste ready, with detailed explanations of which method to use when.
