Fit div to inside contents - html

Question

I have a background div that I use to create a "box" effect. I need this div to fit its contents but what I searched and tried to do, did not worked as expected. I'm using bootstrap.
I already tried in my div css:
display:inline-block;
display:inline-block !important;
This is my page without above css:
This is my page with above css
And this is what I need. My background "box" limit in the red line:

Answer 1

The main issue I see is you're using the Bootstrap col- classes so your contents are being forced to fit in the grid. Specifically, it appears most the rows of your layout are only using 6 out of the 12 columns of the grid, which results in the form taking up only half the available width.
You'll want to make sure the col- classes add up to 12 for each row.
For the purposes of this demo I've used the col-xs- classes so the layout fits within the narrow demo frame below. You'll probably want to use the responsive classes to the form works well across more viewport sizes.
.input-content-boxed {
background-color: #ffffff;
padding-left: 15px;
padding-right: 15px;
padding-bottom: 15px;
padding-top:15px;
border-radius: 3px;
box-shadow: 2px 2px 3px #888888;
display:inline-block;
}
