Build a Banner for Mobile Devices

To deliver the best customer experience for your customers, you may want to limit certain Monetate experiences to certain device types. This Action Builder and Web experience use case includes building an action to display a particular banner and adding it to an experience so that the banner appears only when a customer arrives on your site using a mobile device.

Inspecting the Site in Device Mode

Follow these steps to use the Google Chrome browser and its Developer tools (DevTools) to gather key information about your site that you'll need for the action you build.

  1. Load a page of your site in the Chrome browser, launch Chrome DevTools, and then click Toggle Device Toolbar in the top navigation bar.

    Chrome DevTools' Device Mode is not 100% accurate, but you can nevertheless use it for reference. Monetate recommends that you test experiences on specific devices. Refer to Google's Simulate mobile devices with Device Mode documentation for more information about the tool's limitations.

  2. Click Dimensions at the top of the window, and then select a mobile device option.

    Callout of the Dimensions selector and a view of its device options in Chrome DevTools' Device Mode

  3. Find an element on the page that appears only on mobile devices. First, click Inspect to the left of Toggle Device Toolbar in Chrome DevTools, and then place your mouse pointer on various elements to find one that only appears on mobile devices.

  4. In the Styles panel of Chrome DevTools, find the @media only screen and (max-width: [value]) property, and then copy and preserve the information for later use. If the @media only screen doesn't appear in the CSS in the Styles panel, it may in the CSS for a theme that's applied to the element. Click the theme link to view and, if necessary, search for the @media only screen and (max-width: [value]) property.

    The max-width property defines the maximum width of the mobile device viewport. See CSS @media Rule from W3Schools for more information.

Once you've recorded the @media only screen and (max-width: [value]) property, you can build the banner action in Action Builder.

  8. Take the following actions to center the banner image below the navigation bar:
    1. Input into Banner Div Inline Style the CSS to center the banner container.
      width: 100%;
      display: block;
      padding: 0;
      margin: 0;
      position: relative;

      The Details tab in Action Builder, with the required CSS added to the 'Banner Div Inline Style' field

    2. Input into Image Element Inline Style the CSS for the banner image. The value of max-width should be 1 pixel larger than the value of the max-width property for mobile devices.
      display: block;
      width: 100%;
      max-width: 552px;
      margin: 0 auto;

      The Details tab in Action Builder, with the required CSS added to the 'Image Element Inline Style' field. The action preview shows the banner placeholder centered in its correct position relative to the header.

  9. Click the Styles tab in Action Builder, and then take the following actions:
    1. Copy and paste this CSS into the editor:
      #monetate_selectorBanner_[unique ID] {display: none !important;}
      @media only screen and (max-width: [value]){
        #monetate_selectorBanner_[unique ID] {display: block !important;}
    2. Replace the [value] placeholder in @media only screen and (max-width: [value]) with the actual value you recorded in the final step of Inspecting the Site in Device Mode.

    3. Use Chrome DevTools to inspect the banner preview, and then copy the unique ID (for example, id="monetate_selectorBanner_4557ca77_00").

    4. Return to the Styles tab, and then paste the unique ID to replace the two placeholders in the CSS.

      Because the completed CSS prevents the banner from appearing when the viewport is greater than 551 pixels, Action Builder's preview function can no longer show the banner action in progress on your site.
