A client came to me recently with a classic request: “I want my WooCommerce product gallery to look like Pinterest.” That sounds simple and it never is. Anyone who has spent time in the WordPress world knows that a clean CSS masonry layout has been miserable to build for a decade. I have tried all of it: multi-column layouts that break reading order, heavy JavaScript libraries that tank Core Web Vitals, even some sketchy SVG hacks.
Normally I would reach for a library like Masonry.js, but on a high-traffic shop another 20KB of render-blocking script just to position a few boxes feels like a defeat. It is a sledgehammer for hanging a picture frame. So the news about grid-lanes is genuinely welcome to anyone building sites for a living.
The “clever” hack that fell apart
About two years ago I thought I had outsmarted the problem. I built a masonry grid out of standard CSS Grid by giving the container a 1px row height and calculating grid-row-end: span X for every item in PHP. It felt elegant right up until the client started uploading images with odd aspect ratios, and the layout turned into a jigsaw puzzle assembled by a toddler. Faking masonry with standard grid math is how you earn a 3 AM support call.
CSS-Tricks has the story of how that argument finally ended with a native solution. The answer turned out to be a new display property called grid-lanes rather than a “Pinterest mode” switch.
Why grid-lanes and not a masonry keyword
The CSS Working Group spent years on this. Some members wanted to add a masonry keyword to the existing grid properties, which would have bloated the layout engine. They landed on display: grid-lanes instead. It is cleaner, and it understands how items should flow when their heights do not match. Here is what theme code is going to look like:
/* The future of CSS masonry layout */
.bbioon-product-grid {
display: grid-lanes;
gap: 1.5rem;
/* You can still use familiar grid template logic */
grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
}
/* We can even control the packing logic */
.bbioon-product-grid-compact {
display: grid-lanes;
item-flow: collapse;
}The performance side is the part I care about. Moving the layout logic into the browser engine means we can ditch the heavy JS libraries we have leaned on for years, which is the same instinct behind any complex WordPress performance optimization: less code doing more of the work.
Is it ready for production?
Not yet. Chromium, WebKit and Mozilla have all agreed on the grid-lanes syntax, but it is still rolling out behind flags. You can follow progress on the Chrome Status page or read the current implementation guides on MDN Web Docs. For now a lightweight polyfill may still be the right call, though the multi-col hacks are on their way out.
Where that leaves you
- Do not over-engineer this. Native CSS positions boxes faster than JavaScript ever will.
- Wait for support before you refactor anything, but start planning the move off external scripts.
- Readable templates matter, and
grid-laneskeeps both your markup and your CSS easy to maintain.
This stuff gets complicated fast. If you are tired of debugging a broken layout and you just want a site that is fast and looks right on every screen, drop me a line. I have been doing this for 14 years, and I have probably already solved the exact mess you are staring at.
