How can I add custom code to my Wix website? | More resources

Adding custom code to your Wix website is straightforward with multiple methods available depending on your technical expertise and needs.

Using HTML Embed Elements

The simplest way to add custom code is through Wix's HTML iFrame element. Navigate to the Add menu in your Wix editor, insert an HTML iFrame embed element, and paste your custom HTML code directly. This method works perfectly for embedding third-party widgets, forms, maps, or chat tools without requiring coding knowledge.

Velo by Wix for Advanced Functionality

For more sophisticated customization, Velo by Wix provides a full-stack development environment within Wix Studio. With Velo, you can write JavaScript to create dynamic, interactive features, handle user events, and fetch external data. The platform also supports backend serverless code for API integrations and managing database collections. This gives developers complete control over site interactivity and logic.

Custom CSS Styling

Wix Studio allows you to add custom CSS through the Code Panel for precise design control beyond standard theme options. You can apply CSS globally or to specific components, creating custom classes and assigning them to page elements to achieve your exact design vision.

Backend API Integrations

For secure integrations, Velo supports making protected API calls from backend code using Wix's Secrets Manager to safeguard sensitive credentials. This enables you to connect with external services, handle payments, or integrate third-party APIs seamlessly while maintaining security best practices.

Development Environment Options

You can code directly in Wix Studio's built-in Code panel, use the Wix IDE (based on VS Code), or work with your preferred IDE through GitHub integration. This flexibility accommodates different development workflows and team collaboration needs.

Best Practices

Always ensure embedded third-party code comes from trusted sources to maintain site security. A premium Wix plan is required for most custom code features. When adding scripts, use async/defer attributes or backend calls to prevent performance issues.

Whether you're a beginner adding simple embeds or a developer building complex functionality, Wix provides the tools to extend your website with custom HTML, CSS, and JavaScript code.
