Styling and formatting in the WYSIWYG editor

Learn how to build your message using body settings, blocks, and individual content elements.

Styling sections

The editor has three styling sections, accessible from tabs in the sidebar:

  • Body — Settings that apply to the entire message.

  • Blocks —  Blocks are single- or multi-column layout sections, and they are synonymous with content columns. You can leave blocks unstyled, style columns or rows independently, and add content elements.

  • Content — Add columns, buttons, dividers, text, images, etc., individually or to a block.

Drag and drop blocks and content to create a layout, then edit settings to complete styling the message.


The last section on each tab is Responsive Design, with options:

  • Hide on Mobile/Desktop — Hides a content element from view. If you create different versions of the same content element for both desktop and mobile, use this option to make sure only the relevant version is viewable in the right context. For mobile, you may want to use this option to hide images and other elements that take up an inordinate amount of the screen in your message.

  • Do Not Stack on Mobile — Prevents columns in a row from stacking on a mobile device or when the client width is less than the Content Width (essentially the mobile breakpoint). You can set the Content Width in the Body section of the editor.


When editing a block or content element, click   to duplicate it,   to delete, and   to close the editing options and return to the top-level options for Blocks or Content.

 Tip

Use blocks or content columns to lay out your message before you add content. You can add multiple content elements to a single column. For example, you can place text above of an image, and both items will be grouped together in the collapsed mobile view.

Body styles

Body styles affect the entire body of the message.

  • Background Color — Set the background color for the entire message, both in and outside the content-width. You can override this setting at the row and column levels.

  • Background Image — Enter the HTTP/HTTPS URL of an image, then set its options.

    If your Airship plan includes CDN support, you can also upload an image or select from previous uploads.
    1. Click Upload Image.
      1. Click Choose file and select a file to upload, or select from previous uploads.

        • The default sort order is most recent upload first.
        • You can search by file name or keyword.
        • A file preview appears after upload or selection. Click   to preview audio and video files.
      2. (Optional) Add or edit keywords for the file to help organize your uploads.

        • Enter a term in the search field below the preview and select from results, or click Add keyword: [term].
        • Click   to remove a keyword.
      3. Click Insert selected media.

    2. Content Width — Set the content width of your message. This is generally helpful for email, as it represents your mobile breakpoint as well; when a client width is less than the content width, columns will collapse and cells will stack (unless you set mobile settings denying collapsibility).

    3. Font Family — Set the font for your message. You cannot override this setting at the row or column level.

    4. Links — Configure the appearance of links in the message.

    Blocks and content columns

    Blocks are identical to the Columns option in Content. They are background elements that help you layout your message before you add content. When you select a cell in a column, you can style the entire row or set styles for individual columns within the row. Most of the style options are the same for both rows and columns.

    Add a single column or row of columns, then style each column and the row. To resize the column widths, click and drag the dividers, and the width percentages display in the sidebar.

    Row properties

    Row properties affect the entire row. If you want to set properties for individual columns in a row, go to Column properties.

    • Background Color — Set the color for the entire row, extending to the entire width of the window, not just the width of the content body.

    • Content Background Color — Set the background color for content body in the row.

    • Padding — Set padding — spacing inside the border — for all columns in the row. Use More Options to change padding for individual sides of the row.

    • Background Image — Set an image as the background of the row. You can overlay the background image with other content elements. Enter the HTTP/HTTPS URL of an image, then set its options. See: Media guidelines.

      If your Airship plan includes CDN support, you can also upload an image or select from previous uploads.
      1. Click Upload Image.
        1. Click Choose file and select a file to upload, or select from previous uploads.

          • The default sort order is most recent upload first.

          • A file preview appears after upload or selection. Click   to preview audio and video files.
        2. (Optional) Add or edit keywords for the file to help organize your uploads.

          • Enter a term in the search field below the preview and select from results, or click Add keyword: [term].
          • Click   to remove a keyword.
        3. Click Insert selected media.

      Column properties

      Column properties affect an individual cell in a row. Click   to add another column to a row, or   to delete.

      • Background Color — Set the background color for the individual cell.

      • Padding — Set padding — spacing inside the border — for the cell.

      • Border — Add and style a border for the cell, helping you provide visual separation between rows and columns where necessary.

      Content elements

      Content elements consume the width of the column you place them in. Content elements that are not contained in a block are rendered full-width. Drag a content element into your message, then click the element to see its styling options.


      When configuring a content element, select the Desktop and Mobile tabs for their different settings and options. Your message view in the editor updates dynamically when you switch tabs.

        Preheader text for email

        When creating the HTML body for email using the WYSIWYG editor, the first line of text in the message also appears as the Preheader TextA short line of text that displays after or below an email subject line in an inbox. You can also have the text appear in the message body. Preheader text is an easy way to expand on your subject line and improve email open rates. Not all email clients support preheader text. in the inbox. If you want to add preheader text that appears in the inbox only:

        1. Select the Body section from the sidebar.

        2. Under Email Settings, enter text in the Preheader Text field.
