How to Use the Layout Mockup Builder

To use the Layout Mockup Builder, start by clicking a block from the left palette and adding it to the canvas. Blocks will appear in the order you add them.

When to Use the Tool in Real Workflows

The Layout Mockup Builder is ideal for designers and developers who need to quickly create and preview page layouts. It's particularly useful when working on marketing pages, blog posts, and other projects where a clean, responsive design is essential. By using this tool, you can save time on the design phase and ensure that your final product is visually appealing and user-friendly.

How It Works

The Layout Mockup Builder allows you to drag-and-drop pre-designed blocks onto a canvas to create a page layout. Each block represents a different structural element of a web page, such as a header, navigation bar, or footer. Once you've added and arranged the blocks, you can preview the layout in real-time. The tool also provides an option to export the layout as clean HTML and CSS code, which can be directly used in your development environment.
