Does this help?? This code appears at 320px but it probably should be by default.
#bbpress-forums div.wp-editor-container {
width: 100%;
overflow: auto;
}
Thanks, @robkk!
This adds a vertical scrollbar only, same cut off width (have it at 320er query already).
Hugging all elements of the forms (tested via form-reply.php) with a new, then styled div, as the form-legend shall be also responsive, also does not work.
Just don’t find the reason, will have another look.
ok found it, it’s caused by the GD bbPress Attachments plugin I’m using. sorry and thanks!
