Is there any way to skip/remove/block ads before video on this website? - http://motobanda.pl/motocyklista-uderza-w-jelenia-na-drodze

To reproduce, click play button on video and you will see ads.

I tried this rule ||motobanda.pl/uploads/avid/*.mp4$media, but it does not work, because with this rule video does not play.

I observed that after ads, this element id="mvideo" changes z-index from -1 to 1.
So it would be nice if uBlock had an option to change style for elements on websites, something like Adguard has - https://adguard.com/en/filterrules.html#cssInjection

With Adguard I can change style for this element using this rule - motobanda.pl#$#body #mvideo { z-index: 1!important; }
and I can watch video on this website without ads.

With this it would be also possible to skip timer on some other websites, for example here - http://gahe.pl/graonline,17859,boom-bad-piggies-wysadzanie-%C5%9Bwi%C5%84
Now I must wait 20 seconds to play a game.

If it would be possible to change style for elements, I could play a game immediately.
As an example again rule for Adguard - gahe.pl#$#body #flashgame { display: block!important; }

and here - http://alltube.tv/film/minionki-the-minions-2015/27966
I must wait about 10 seconds to watch video.

With this rule I can skip this - alltube.tv#$#body #iframe-container { display: block!important; }

and here - http://www.vipfullhdfilmizle.org/13-saat-bingazinin-gizli-askerleri-turkce-dublaj-izle/2/
I must wait about 6 seconds to skip ads.

With these rules I can skip this:
vipfullhdfilmizle.org###VideOnrekLam
||savoy.storage.cubecdn.net/bm/vipfullhdfilmizle/*.mp4
vipfullhdfilmizle.org#$#body #kendisi{ display: block!important; }

So it would be nice if uBlock Origin had an option to change css style for elements on websites.
Or maybe someone have an idea how to skip/remove/block ads/timer using uBlock Origin on these websites without changing css style?
