FAQ
Will custom code affect my site’s mobile responsiveness?
I ensure all custom CSS and JavaScript is written with a "mobile-first" approach. I test every customization on multiple screen sizes to ensure your site remains perfectly responsive and functional.
Will this code slow down my website loading speed?
I prioritize lightweight, clean, and optimized code. I write only what is necessary to achieve your vision, ensuring your site remains fast and performance-friendly according to Squarespace’s best practices.
What if Squarespace updates its platform? Will my custom code break?
I use standard, well-documented coding practices. While no custom code can be 100% immune to major platform engine changes, I write my code to be as modular and stable as possible. I also provide clear comments in the code so any future developer can easily manage it.
Can you implement features that aren't native to Squarespace?
I can add functionality like custom sliders, interactive animations, dynamic filtering, or custom third-party integrations using JavaScript. If a feature is fundamentally impossible within the Squarespace environment, I will be upfront and offer the closest possible workaround.
Do I need a Business or Commerce plan for this?
Yes. To use CSS and Code Injection, Squarespace requires a Business plan or higher. Please ensure your account is upgraded before we begin so we have access to the necessary code-injection areas.
