Is there a way to decrease the amount of space the amount of space in the margins to increase the room for content? Would that ruin the responsive nature of the theme?
Add this code to Theme Options - Other - Custom CSS and tweak pixel value to get the padding you were looking for.
.post-inner-content {
padding: 25px;
}
No, this code won’t affect theme responsiveness as it will not adjust theme width but just content padding.
will that decrease the padding (margins) on every page? or just posts?
It should work for blog index page, pages and posts as they have the same class applied to them. If you need more specific code for posts, pages or just blog index, please let me know.
I don’t know if I am applying the code you gave me correctly but could I get code to decrease the left and right margins on pages to increase the content width?
Ok, then ignore the previously given code. Your web design terminology is a bit confusing 
Add this code to Theme Options - Other - Custom CSS
@media (min-width:1200px){
.container.main-content-area {
width:1370px;
}
}
.single-featured {
width: 100%;
}
It will make content area wider by 200px. I guess this is what you were trying to achieve, right?
You can also modify width if it looks too small or too big.
Hi,
The picture of my headboard has got margins, how may I change it to occupy tho whole width of the screen.
Thank you
