post has its own background

Hello,

The easiest way to have your post use a different background is to use post template style 8: http://demo.tagdiv.com/newspaper/td-post-2015-awards-all-of-the-best-and-worst-moments-from-the-show/ this will grab the post featured image and use it as a background.
As an alternative, you can override the post background with css. You will need the unique post id you can get from here: http://screencast.com/t/MONR30SLy2u
Then you can use this id as a css class and use this code to change the background:

.postid-957 .td-backstretch {
display:none!important;
}
.postid-957 .backstretch{
background-image: url('http://wowslider.com/sliders/demo-5/data/images/saarschleife.jpg');
background-repeat: no-repeat;
background-size: 1920px 1080px;
}

I hope this helps.
Thank you!

Hello,
Unfortunately it cannot be full width. Our theme depends on a fixed with and all the elements are positioned based on this fixed with. It will be a very difficult task in making the site full width as all the elements need to be adjusted. If you really need this customization, we recommend you hire a freelancer from sites like studio.envato.com
Thank you!

Hello,
We always try to improve our theme as much as we can on every update. We will add more and more post styles and blocks and modules with every major update. This is one of our goals, to offer as many options as possible so the user can chose from a large amount of features, but this takes time and effort and cannot be done quickly.
Thank you for your suggestion. I will add this to our list of updates and pass this information on to the dev team.
thanks.
