Get started with Handoff

 

 

The Handoff Tool is the ultimate bridge between your design and development teams in Marvel.

Handoff automatically turns designs and prototypes into pixel-perfect development specifications including code and assets, right next to the interactive prototype.

With Handoff, your project in Marvel is the spec doc - No need for the time-consuming task of red-lining or creating never-ending PDFs each time your design changes. Simply share your Marvel prototype with your developer and they can get all the information they need to create the screens to your exact specification. Everything stays updated in real-time so you’ll always know that Marvel is the source of truth for your project.

How to get started

Enable and view Handoff on your projects

The Handoff tool is automatically enabled for images synced from Sketch or images created using our Design tool

If you're syncing artboards from Sketch, please ensure you're using the latest version of the Sketch plugin which you can download here.

Is the Handoff button disabled?

This is likely because the image wasn't uploaded from Sketch or Marvel's built-in Design Tool

 

Access Handoff:

Open your project and hit the Play button in the top right-hand corner 

In the bottom left-hand corner of the screen, click on the Handoff button to access the developer specifications and assets

Note: If the designs haven’t been uploaded using Marvel for Sketch or our Design tool, then the button will be greyed out.

 

Using Handoff:

Once Handoff is open, it’s an absolute breeze to start getting measurements, code and assets. When you first enter Handoff without any elements selected, you’ll see the screen level properties.

Here you’ll find two sections: Artboard and Assets

Downloading assets

The Asset section stores all the layers and assets for the screen which you can download individually or as one ZIP file with everything contained.

You can export the same element in multiple sizes e.g. 1x, 2x etc based on your layers.

Note: Sketch users will need to mark layers as exportable in the formats needed. Here's how.
