Can't block div and video

[BratSinot]

On some site we have HTML5 video-player with ads.
P.S. For example this video.
If we block www.xn----etbbecbrbp5ahkja1ae7v.xn--p1ai/videoreklama advertising will not be displayed.
But in code we have 2 tags div and video with elite_vp_videoPlayerAD class.
Then i try block they, like this "##.elite_vp_videoPlayerAD", or this "##div[class="elite_vp_videoPlayerAD"]" uBlock just didn't seem them.

I use Chromium 58.0.2988.0 and latest uBlock Origin.

It's inside an iframe, the picker works only on top document, not embedded document.

Duplicate of #1744.

If you know the hostname of the iframe which contains .elite_vp_videoPlayerAD, then just manually add the filter in "My filters" pane: example.com##.elite_vp_videoPlayerAD.

Looking at your screenshot, you might have been looking for kingisepp-today.ru##.elite_vp_videoPlayerAD.
