Bootstrap container-fluid padding

Answer 1

In this case, the column is actually causing the padding, which is written into the bootstrap .css file.

You didn't mention what version of Bootstrap you're using, I assume 3.x?

I usually add a custom class to my own .css file to eliminate padding when it's not wanted, such as:

.noPadding {
padding: 0 !important;
}

Then add the class to your column like so:

    

        

            test

Bootstrap 4 will include padding and utility classes to manipulate padding more precisely. Read about it here
