Cleaning Up the Mess with Modern CSS Architecture

A client came to me recently with a WooCommerce store that felt like it was stuck in 2012. It looked okay on the surface, but the navigation was clunky—lots of white flashes between pages. They’d previously hired a dev who tried to “modernize” it by throwing a massive JavaScript library at the problem to handle smooth page transitions. Here’s the kicker: that library ended up hijacking every internal link, breaking their Google Analytics tracking and half their checkout fragments. Total nightmare.

My first instinct, honestly? I tried to fix the JS bridge. I spent a good few hours digging into lifecycle hooks and trying to force the scripts to re-initialize after each page swap. I thought I could just patch the mess. Trust me on this—that was a mistake. I was fighting the browser instead of working with it. The real solution was to strip out the bloat and lean into modern CSS architecture.

The Power of Modern CSS Architecture

We’re entering an era where the browser handles things we used to need 50kb of script for. I’ve been following a lot of these updates lately, especially through some great roundups like the one over at CSS-Tricks. One of the most promising shifts is toward native View Transitions. Instead of a heavy JS library, you can now trigger different transitions based on the URL context. Bramus pointed out that CSS navigation matching is on the horizon, which means we’ll soon handle complex page flows without a single line of JavaScript. That’s the kind of clean architecture that actually scales.

Another thing I see devs mess up constantly is naming conventions. They use generic classes like .btn or .card and wonder why their styles leak everywhere. In 2025, you should be namespacing everything. If you’re building a design system, use a prefix. It keeps your CSS semantic and prevents the “specificity wars” that usually end with a hundred !important tags.

/* The right way to namespace your UI components */
.bbioon-ui-button {
    all: unset;
    display: inline-flex;
    padding: 0.5rem 1rem;
    paint-order: markers fill stroke; /* A neat trick for SVG text effects */
}

@property --bbioon-accent-color {
  syntax: '<color>';
  initial-value: #0073aa;
  inherits: false;
}

I also caught an interesting point about accessibility tokens. Geri Reid suggested annotating design system components for things like ARIA labels and zoom preferences as tokens. This isn’t just “nice to have”—it’s essential for high-traffic sites where you can’t afford a lawsuit or a frustrated user base. When you bake accessibility into the HTML markup and CSS tokens from day one, you don’t have to retroactively fix it when it breaks.

Stop Fighting the Browser

Whether it’s using paint-order for better text rendering or implementing displacement maps for high-end effects (shoutout to Ana Tudor for some wild demos on Bluesky), the goal is always the same: do more with less code. Projects like Interop 2026 are making sure these features actually work consistently across Chrome, Firefox, and Safari. So, there’s no excuse to keep using outdated, heavy-handed workarounds. Period.

Look, this stuff gets complicated fast. If you’re tired of debugging someone else’s mess and just want your site to work with the browser instead of against it, drop my team a line. We’ve probably seen it before.

Are you still relying on jQuery for page transitions, or are you ready to give the native View Transitions API a shot? Trust me, your lighthouse score will thank you.
