Style your native ad in the Guided design editor

When you select the "Guided design editor" option to create a native style, use the UI controls to style your native ad to match the look and feel of your website or app. Updates are automatically applied to the ad preview on this page, which allows for experimentation.

You can edit CSS directly, but:

• You won’t be able to make additional changes through UI controls once you do so.
• If you introduce policy errors when editing the CSS, the native style will lose Ad Exchange auction eligibility but can still serve through Programmatic Guaranteed.
• HTML is not editable in the Guided design editor. For more customization, you can choose the HTML & CSS editor option, but you’ll lose programmatic eligibility.

1. When creating a style with a “Fluid” size, you can update the “Preview width” setting to see how your ad looks on different screen sizes.
   You can also drag the blue bar to change width. Height is updated automatically.
2. Click Reorder elements to show/hide the elements within each card on the right panel and rearrange them.
   For example, you could move the call to action above the advertiser name and remove the advertiser logo. Learn more about Standard native ad formats.
3. In the right panel, expand an element and update the settings as needed. For example, expand:
   • Title to select whether you want your ad's title, or headline, to have a maximum of 30 characters (Short) or 90 characters (Long).
   • Body to change the color of the body text
   • Various elements to increase the font size.
