Offer content must contain exactly one HTML element

I tried creating an HTML Offer in Adobe Target, which contained HTML <div>...</div>, a style block <style>...</style>, as well as a script blocks <script>...</script>, but when I tried to insert the offer into an activity, it gave the following hard stop error message: "Offer content must contain exactly one HTML element". 

 

I wasn't sure what that means, but I could only assume for now that it's because I'm trying to include a style block and/or a script block in the offer, though the language of the error message focuses on there being more than "one" HTML element....

 

Any clarification here would be great. Thanks.

Hi @maccg12  ,

If you're seeing this error while creating an HTML offer in Adobe Target, it's because Target expects the entire offer content to be wrapped in a single root HTML element.
For example, if your offer includes this:
<div>My content</div>
<style>...</style>
<script>...</script>
You're technically including three separate top-level elements, which violates Target's requirement.
You can try by wrapping everything inside one parent <div>, for example :
<div>
<div>My content</div>
<style>
/* Your styles */
</style>
<script>
// Your script
</script>
</div>
This ensures the offer has exactly one HTML element at the top level, which satisfies the validation rule.
Inline <style> and <script> blocks may be sanitized or restricted depending on your Target setup (for security reasons).
For advanced logic or styling, consider referencing external JS/CSS files hosted on a secure domain.

Hope It helps!
Thank you !!

    Thanks for the clarification. 

    I had since learned that perhaps a better way would be to include the <style> block inside the head section using the VEC option for custom code, and then also to add the <script> block to the body by also using the custom code option for modifications in the VEC.
