When a video file (.mp4) have a thumbnail, the image overlap the title, like the example below:

Hi @gtso86
Could you please provide me with more information? What field type did you use? If you could share the JSON export of the field group, that would be great.
Thanks!
Hi @gtso86
Could you please tell me how did you add the thumbnail? It seems I can’t do it in my installation.
I believe you can fix it by using a custom CSS code. You can use the “acf/input/admin_head” hook to add the custom CSS code. This page should give you more idea about it: http://www.advancedcustomfields.com/resources/acfinputadmin_head/.
I hope this helps.
Sure!
You Media and edit a video file and select a image via featured image box. The imaged selected will be attached to the video.
Hi @gtso86
This is weird. I already did that, and the field thumbnail doesn’t change at all. But I believe you can fix it using this code:
function my_acf_admin_head() {
?>
<style type="text/css">
.acf-file-uploader .file-info {margin-left: 100px;}
.acf-file-uploader .file-wrap {min-height: 100px;}
</style>
<?php
}
add_action('acf/input/admin_head', 'my_acf_admin_head');
I hope this helps.
