A landing page that can't break the rest of the store
Steadyrack needed a campaign landing page for their ProFlex rack, a long-form page designed band by band: hero, steps, reviews, a before-and-after slider, comparison table, FAQs. The design work was done. The build question was the one that decides whether a landing page is cheap now or expensive later: do you bend the store’s existing sections to match the design, or give the page its own?
What we did
Before deciding, we measured the blast radius. The theme’s main banner section is used by seventy-two templates. The featured products section by thirty-four, the FAQ section by thirty-one. Editing any of them to satisfy one campaign page means every one of those pages is exposed to the change, and campaign pages get tweaked constantly, right up against deadlines, which is exactly when nobody is re-checking seventy-two other pages.
So every section on this page is its own fork, fourteen of them, each carrying its own styling scoped to its own instance. We audited every selector to confirm nothing leaks: the landing page’s CSS is emitted only on the landing page, and the coupling runs one way, drawing on the store’s design tokens without writing anything back. The page can be restyled, rearranged or deleted and the rest of the store cannot feel it.
The comp also got upgraded where it drew pictures of controls. The before-and-after slider’s drag handle was an image in the design; it shipped as a native slider control, focusable and keyboard-operable, because a control drawn as an image is a control some customers cannot use. The FAQs are native disclosure elements that need no JavaScript at all.
What to take from it
Landing pages have a habit of being built quickly against shared code, and the cost surfaces later as mystery regressions: a heading that changed sitewide, a banner that shifted on pages nobody was looking at. The isolation is invisible in the launch screenshot, which is why it is worth asking for by name. When someone builds you a campaign page, ask what else on the site can change when it does. The right answer is nothing.
