By default, any Button layers in your designs will be set to be fluid on mobile and expand to the width of the Column (depending on the size of the mobile device screen viewing the email).

You can change this behavior on mobile by clicking your Button layer, then clicking the Settings layer in the plugin header, and toggling the Full Width Button on Mobile toggle option on or off.

If the width of your Button in the Figma (desktop) design exceeds 300px, the button will automatically be exported as Fluid, otherwise the longer fixed width button would push out the side of the layout on smaller screens.

If your Button layer itself is set to Fill container in your Figma design, Emailify will also preserve the button's horizontal auto-layout alignment in the exported HTML. This means you can left align, center align or right align the button text inside a full-width button by changing the button's auto-layout alignment in Figma.

If a long variable or placeholder makes your button too wide before it is replaced with a shorter label, set the text layer inside the Button to Fixed width and enable Figma's Truncate text option with Max lines set to 1. Follow the button placeholder sizing steps.

You can apply settings in bulk by opening Settings, then selecting multiple Emailify layers of the same type in Figma. Any setting you change will be applied to all selected layers.
