Dark mode, zero page builder, delivered in 1 day: the Contabilidade Spazio website

The context

Contabilidade Spazio was founded in September 2021 in São Paulo. In 2026, with the firm growing, came the need for a website that communicated professionalism without looking generic — the problem with 90% of accounting firm websites in Brazil, which are indistinguishable from one another: white background, handshake photo, "complete advisory services for you."

The decision to go against the grain

We proposed dark mode. Not as a gratuitous aesthetic differentiator, but as positioning: dark mode in the accounting market is uncommon enough to create memorability, and technically communicable — it signals that the firm thinks differently from its competitors. The client embraced it.

The palette started from the existing logo: #08080A for the background, deep #005020 as the brand color, and bright #22C55E as the accent. Cormorant Garamond for headings — a nod to the same choice on the Crazy Diamond website — and Inter for body text. The result looks more like a premium fintech than a conventional accounting firm.

Zero page builder

Hosting was HostGator shared, no SSH, FTP access only. Environments like this tend to push you toward Elementor out of convenience — drag and drop with no terminal. We chose the opposite path: a child theme of Hello Elementor, with zero dependency on any page builder.

The reason is technical and practical. Elementor injects JavaScript even for elements that don't need JS. On shared hosting where the server responds more slowly, every KB counts. With plain PHP and custom CSS properties, the generated HTML is predictable, Lighthouse stays controllable, and future maintenance doesn't depend on any paid plugin keeping up compatibility.

9 WhatsApp CTAs — one per context

No contact form. That decision was deliberate: accounting firms in Brazil close deals over WhatsApp, not email. A form adds friction without adding conversion.

Each of the 6 services has a WhatsApp CTA with a different pre-formatted message. "I'm interested in Accounting Advisory..." is not the same message as "I'm interested in Financial BPO...". When the lead comes in, the firm already knows exactly what they want — no manual qualification needed. Add the floating button, the navbar, the hero and the banner CTA: 9 exit points, zero friction.

Security on shared hosting

Shared hosting is a higher-risk environment than a VPS — you share the server with dozens of other clients. We implemented hardening on two layers: .htaccess and functions.php.

.htaccess: forced HTTPS with a 1-year HSTS policy, X-Frame-Options SAMEORIGIN, X-Content-Type-Options nosniff, X-XSS-Protection, Referrer-Policy strict-origin-when-cross-origin, blocking of xmlrpc.php (a common vector for WordPress brute-force attacks), and blocking of author enumeration via query string.

functions.php: /users REST API endpoints removed (user exposure), author pages returning 404, Customizer fields so the client can edit their WhatsApp number, address and social links without needing a developer — and without needing code access.

Result

From briefing to live site in 1 day. 5-star review on 99Freelas: "Fast and efficient. I recommend." The client has full autonomy to update contact details without depending on Crazy Diamond. The site is indexed, has a sitemap, and uses AccountingService schema for rich snippets on Google. Production-ready from day one.
