That’s weird.

I think it is a combination. For some reason, when reduction hits the 1030px mark not only the CSS changes – which we might expect – bit it seems the HTML changes as well. This brings into play our SP ‘base-reset’ css (within the Reboot styles folder) which sets the default padding to zero. And that is what it does not seem to like…

You could try changing that – actually you would need to remove the padding statement from the base-reset (the big list of elements). Might be worth doing to see if that (a) fixes the problem and (b) to see what other knock-on effect such a change might make.

If all is well we may be able to come up with a useable long-term solution.

Thanks Andy, that theme has a separate responsive.css file that must take over when the screen reaches a certain resolution.I believe 1030px is the themes default sheet width, had to fiddle here and there to make everything fit within the containers.

Will try your suggestion tomorrow.

let us know how you make out…

Tried removing the padding line with no changes.

odd – that worked for me.
there is also a setting on the new div that the video is contained in that sets the height to zero. Try removing that as well.

Nope.. Deleted the cache, including CloudFlare but no help.

so, does it work with other themes?

Yes other themes works fine. Videos have never worked with simplepress and my Artisteer theme, just decided i like Artisteer for what is is (now abandon ware) and was hoping to figure it out.

I’m lost in code anyway.. Though getting somewhat better in my golden years. I was hoping it was a code snippet that disabled the sidebar in responsive mode, but removing that didn’t help either.

I gave up on that theme. Ran a theme test plugin and found pages of errors and obsolete code. 

The last software update was 2014. They came up with a Themlier project that was supposed to supercede Artisteer but apparently that flopped and is said to be abandon ware as well. Dumb idea using wordpress as a theme generator (in my humble opinion.) 

Too bad, Artisteer had a ton of theme design options, but they never did get the responsive option correct. Oh well.. Life goes on! 

Thanks for your help. 

sorry to hear… let us know how you get on with new theme and if you have any questions…
