# Custom

The **Custom Block** gives you the freedom to design completely personalized layouts within your customer account pages — no coding required. Use it to create anything from simple callouts to full dashboard-style sections that perfectly match your brand and needs.

### Key features

* **Visual builder:** Build layouts with a flexible drag-and-drop interface — add grids, text, headings, stacks, and more.
* **Dynamic data:** Insert customer-specific variables like `{{ customer.first_name }}` to personalize content automatically.
* **Conditional display:** Use Custom Blocks as *static* (always shown) or *dynamic* (shown based on conditions) for tailored experiences.
* **Shopify-native:** Runs inside Shopify’s Customer Accounts using UI Extensions — secure, fast, and fully integrated.
