Bootstrap 3附加。无法删除margin-top

Question

I cannot seem to find where the margin-top is coming from when using the affix plugin on my Navbar.

I have [a website here] that may make it easier to see.

Is this something in which I should be using Javascript? I'm not hugely advanced yet on that and so it could be I missed something to do with that. Thanks.

It's not a margin; instead .affix is being positioned 50px from the top of the viewport - just change top to 0 instead:

.affix {
    position: fixed;
    top: 0;
}
