Hi there. Is there any possibility to detect mobile devices on the hubl (server) side? Like in WordPress, there’ s function wp\_is\_mobile() which returns true or false. Or php library mobiledetect which does the same thing. I am creating a custom module, a hero block and it should follow this logic: If desktop → show video as background Else → show image as background I did not see anything like this in documentation, just wondering if it is possible. If not, will have to do it with javascript. ---

@MartinsC - If you really need to do it in HUBL and you’re up to the task, you can use the request headers hubl to detect the user agent and then create a switch to show relevant content: `{{request.headers['user-agent']}}` However, it’s much easier to create both headers and just hide the video background section on mobile and show that version on desktop using CSS media queries * * * If this answer helped, please, mark as solved 😄 * * * [tim@belch.io](mailto:tim@belch.io) | [forms.belch.io](https://forms.belch.io) | Design your own Beautiful HubSpot Forms; No coding necessary.
