While Wix templates provide an excellent starting point, truly memorable websites require advanced customization. This guide reveals professional techniques to push Wix beyond its standard capabilities, helping you create unique, brand-aligned websites that stand out in today's crowded digital landscape.

7. Performance Optimization
Implement advanced techniques to maximize site speed and efficiency.
1. Mastering Custom CSS
Wix's built-in editor has limitations, but adding custom CSS unlocks unlimited design potential. Access the custom CSS panel under Settings > Advanced > Custom CSS.
#button1 {
background: linear-gradient(135deg, #4361ee, #4cc9f0);
border-radius: 50px;
box-shadow: 0 10px 30px rgba(67, 97, 238, 0.4);
transition: all 0.3s ease;
}
#button1:hover {
transform: translateY(-5px);
box-shadow: 0 15px 40px rgba(67, 97, 238, 0.6);
}
2. Leveraging Velo by Wix
Velo (formerly Corvid) opens a world of possibilities with JavaScript. Access the Dev Mode from the top menu to unlock:
- Custom database collections and relationships
- API integrations with external services
- Dynamic page content based on user data
- Complex form handling and validation
- Custom user authentication flows
3. Creating Advanced Animations
Go beyond basic animations with these techniques:
Pro Tip
Use Intersection Observer API with Velo to trigger animations when elements enter the viewport for professional scroll effects.
const observer = new IntersectionObserver((entries) => {
entries.forEach(entry => {
if (entry.isIntersecting) {
entry.target.classList.add('animate__animated', 'animate__fadeInUp');
}
});
}, { threshold: 0.2 });
// Observe elements
document.querySelectorAll('.animate-on-scroll').forEach(el => {
observer.observe(el);
});

4. Responsive Design Control
While Wix offers device-specific editing, true responsive control requires CSS media queries:
@media (min-width: 768px) {
.custom-section {
flex-direction: row;
}
}
@media (min-width: 992px) {
.feature-card {
width: calc(33.333% - 30px);
}
}
"The most successful Wix sites we've customized implement at least 3 advanced techniques. Custom CSS is used in 92% of projects, Velo in 78%, and advanced animations in 65% of premium customizations."
5. Creating Custom Elements
When Wix's built-in elements don't suffice, create your own with HTML iframes or Velo components:
- Custom Navigation: Build mega menus with advanced functionality
- Interactive Data Visualizations: Create dynamic charts and graphs
- Unique Form Elements: Design specialized input fields
- Custom Sliders & Carousels: Implement bespoke content displays
