I will add custom HTML, CSS and js code to fix, redesign and customize squarespace site
Marcus Johnson
About this gig
Your Squarespace site should look exactly how you imagined it. Instead something is off, a layout breaking on mobile, a font that won't change, a section that looks nothing like your vision. You've tried every setting and nothing works.
That costs you. Every day your site stays broken or generic, visitors judge your business and leave.
Custom HTML, CSS and JavaScript changes everything. Need to fix a broken squarespace website design or unlock features your template can't deliver? I write clean code that gets it right.
Here is what you get:
- CSS fixes and custom squarespace styling
- Custom javascript for popups, animations and interactions
- Sticky headers, mega menu and collapsible FAQ section
- Full mobile responsiveness on every screen
- Squarespace 7.1 CSS code injection and fluid engine support
- Custom fonts, hover effects and CSS animations
- Documented code with notes for easy future edits
- Ecommerce and portfolio squarespace custom design support
No messy injections, no code that breaks on updates, no guesswork. Revisions included until you are satisfied.
Message me before ordering so I understand your project and deliver exactly what you need.

If your Squarespace site is slow, outdated, or stuck on version 7.0, you're in the right place.
I build, redesign, and migrate Squarespace websites for small businesses and creatives who need results, not just a pretty page. From new builds to full 7.0→7.1 upgrades with SEO intact and zero downtime, every page is built manually. No AI, no shortcuts. Mobile responsive, SEO ready, and built to convert.
Message me before ordering and let's figure out exactly what your site needs.
FAQ
Will adding custom code break my existing site design?
No, all code is injected cleanly and tested on your live site before delivery. If anything looks off, revisions are included until everything is perfect.
Do you use AI to write the code?
Every line is written manually for your specific site. AI-generated code causes hard-to-trace bugs and breaks on future Squarespace updates, that is exactly what you are paying to avoid.
Will my site still work after Squarespace updates?
Code is written to be update-resistant and clearly documented so any future adjustments are quick and straightforward. Most Squarespace CSS and JS changes remain stable across updates.
Can I edit the site myself after you are done?
Yes, every delivery includes clear notes explaining what was added and where, so you stay in control of your own site.
Does this work on Squarespace 7.1 and 7.0?Does this work on Squarespace 7.1 and 7.0?
Yes, both versions are supported. Just let me know which version you are on when you message me and I will confirm exactly what is possible.
I hired someone before and they left messy code that broke everything. Why would this be different?
That is one of the most common reasons buyers come here, bad injections with no documentation, code that conflicts with the template, and no one to fix it after delivery. Every piece of code I write is clean, scoped correctly, and delivered with notes
What do you need from me to get started?
Just your Squarespace login credentials as a contributor, a clear description of what you want changed, and any reference links or screenshots that show your vision
Is this service for me if I have an ecommerce or portfolio site?
Yes, whether you run an ecommerce squarespace store, a creative portfolio, a service business, or a blog, the fixes and customizations apply equally. Just describe your site type when you message me.
