Setting the width in % as you did in the Simple Post Editor does not work, also tried a max-width attribute to no avail.
Let me say I've always been using fixed resolutions for videos via the Advanced Post Editor. Any video's optimal resolution can be obtained selecting “Nerd statistics” in the drop down right click/long tap video window menu.
Just tried setting the video width in % in the Dimensions left, horizontal box, using the Advanced Post Editor. It actually works, albeit it will look garbled while editing and Preview gets broken. Here it is set at 70% width:
Well, the width porcentual parameter does not work with videos; the forum engine fails to actually detect the correct video parameters and set its height accordingly when used that way. My advice, thus, is to set an actual valid video resolution. Here it is at 854 × 480:
As I mentioned before, this happens in both Firefox and Chrome, only in Simple Post Editor, and only in this thread. Any other thread - it works fine. Just found it very odd.
Does anyone else get the same error when trying Simple Post Editor in this thread?
Dunno, it works for me in Chrome and Firefox. Please try clearing the browser cache or force-refreshing the page now that I made the CSS tweak mentioned before.
Very weird indeed. Could be an extension interfering? It’s something to do with the Javascript on that page. Or maybe somebody inserted some Javascript in one of the posts that is messing with the editor. I guess it’s not a big deal as long as it’s just that one page.
Understanding how to correctly size images is a bit of worthwhile knowledge. If seeing an image that you consider too large or small and then getting into a twist about it is just silly. Maybe not everyone knows what is considered an appropriate size to post. Older people can not see as well as teens and young adults. A large image can be helpful to us old farts. Peace.
