Youtube-Video don't show up in right size

Hello Astghik

Did you find something new about this issue?
In between, I've realized that it's the same issue here in this forum. This youtube video here, has the same black bars, when I view it here on my imac:

So it's probably a generall issue, that could be solved in a softare update?

Thanks for your reply

Hi Daniel,

Please remove the code I provided in the previous code, put the following one and check again. 

#wpforo-wrap .wpforo-post-content .wpf-video, #wpforo-wrap .wpforo-post-content .wpf-video iframe{
    max-width: 98% !important;
}

Hello Astghik

Thanks for your reply.

I've checked it with this code, but it didn't work as well.
In between I've found a solution, that is ok for me so far.

Hope this issue can be solved in further software updates.

Thanks for your help.

Hello, I want the videos to be 100% in width and height.
I can put 100% for the width but I cannot put a percentage in the height. If I put "0" for the height, it doesn't save the value.
I want help.
thanks in advance

Hello, I have cleared the cache after each modification. If I put a number in the height, it works but it is not responsible (normal, it is in pixels). Can't we have 100% in width and 100% in height?
Good night
