The ruler across the top of the Campaign Builder allows you to preview a campaign at different widths.
Click inside the ruler at the top of the Campaign Builder.
The ruler adjusts the preview of the campaign so that you can preview how the campaign will appear on different devices at different widths. ShortStack campaigns are responsive by default, so the campaign and the content on the campaign automatically adjusts to fit the device the viewer is using; though this can be compromised by changing settings and styling. Click inside the ruler to see the campaign at various preset widths:
- 320 pixels: An iPhone held vertically.
- 480 pixels: An iPhone held horizontally.
- 768 pixels: iPad width.
- 820 pixels: Facebook Page Tab App width.
- 1024 pixels: Default width.
Adjusting the ruler only changes the preview width of your campaign. It does not change the actual width of the campaign. To change the max width of the actual campaign, use the Maximum Content Width setting under the Page section under the General tab of the Style Panel.
