Our engineering process focuses on the long-term health, security, and scalability of your digital asset.

Engineering Insights & FAQ

Why is a custom WordPress theme a better investment than a premium template?

Premium templates are designed to fit every possible use case, which leads to massive “code bloat” – hidden scripts and styles that slow down your site even if you don’t use them. A custom theme by Special Case is engineered from a blank slate. You get a lightweight, secure, and ultra-fast digital asset where 100% of the code serves your specific business goals.

Will our marketing team be able to manage content without developers?

Absolutely. We specialize in building “Marketing-Friendly” environments using the native WordPress Block Editor (Gutenberg). We provide your team with a library of bespoke, drag-and-drop blocks that act as “guardrails”. This allows anyone to create new, high-converting pages that always stay on-brand and never break the layout.

How do you ensure the theme is optimized for Core Web Vitals?

Performance is not an afterthought – it is baked into our engineering process. We use modern techniques such as critical CSS generation, intelligent asset loading, and native image optimization. Our custom themes typically achieve PageSpeed scores of 90+ out of the box, ensuring superior user experience and better search engine rankings.

Can you convert our existing Figma or Adobe XD designs into a theme?

Yes. High-fidelity design-to-code conversion is one of our core services. We ensure pixel-perfect accuracy, translating your brand’s visual language into semantic, responsive, and interactive frontend code. Unlike template-based developers, we don’t “force” your design into a pre-existing layout; we build the layout around your design.

What happens when WordPress releases a major core update?

Your site remains stable. We follow strict WordPress Coding Standards (WPCS) and use native APIs rather than relying on heavy third-party “builder” plugins. This clean approach ensures that your theme is forward-compatible, secure, and significantly cheaper to maintain in the long run.

Do we own the source code after the project is finished?

Yes, 100%. We believe in total transparency and zero vendor lock-in. Once the project is complete, you receive full access to the Git repository and own all intellectual property rights. The code is well-documented, allowing any professional developer to maintain or scale it in the future.
