About this gig

Sometimes, a standard template isn't enough. If you're struggling with layout limits or need a feature Fluid Engine can't provide, you need a Squarespace expert who speaks code.


I specialize in custom CSS and JavaScript to break the boundaries of standard design.

I provide clean, optimized code to enhance your site without slowing it down. I bridge the gap between "out-of-the-box" templates and truly bespoke web design.


What I Do:

  • Custom Styling (CSS): Unique fonts, buttons, and gradients.
  • Interactive Elements: Hover effects, animations, and scroll triggers.
  • Functional Scripts (JS): Custom logic and third-party integrations.
  • Layout Fixes: Precision adjustments to margins and mobile alignment.
  • Platform Polish: High-end styling for the "Add to Cart" bar and more.


Click 'Continue' to unlock your site's full potential!
