Sticky Postbit CSS why not working ?

[ogulcan]

Hello why this code not working on my forum? Im using XenBase theme

/* Sticky Postbit */
@media (min-width: @xf-responsiveMedium) {
    .message-user {
        position: -webkit-sticky;
        position: sticky;
        top: 45px;

        .message-userArrow {
            right: -11px;
        }
    }
}
/**********/

Top code changed many time but not helped me.

Thank you.

Hello, looking at your site, there's this CSS loading:

[data-template="ap_ss_user_style_settings_wrapper"] .ap-ss-postbitFilter, [data-template="conversation_view"] .ap-ss-postbitFilter, [data-template*="thread_view"] .ap-ss-postbitFilter {
    padding: 10px;
    max-width: 1280px;
    height: 100%;
}

The height 100% would not allow the sticky to work.

Thank you. Will I have any problems if I remove the Height code?

I don't really know where that CSS is coming from. Maybe this? https://xenforo.com/community/resources/ap-style-suite.8282/

I don't know really know what the purpose of the CSS is.
