I want to collapse navbar when screen size is <=750px.
You can use Bootstrap's customization tool to build a modified version of Bootstrap. From here, you can alter #grid-float-breakpoint to another breakpoint defined by Bootstrap (ie, xs, sm, md, lg).
You need to modified according to highlighted red in below image.
When you're finished, navigate to the Download section, and click On Compile and Download
& then use it bootstrap js & CSS.
Did you not read the docs?
Changing the collapsed mobile navbar breakpoint
The navbar collapses into its vertical mobile view when the viewport is narrower than #grid-float-breakpoint, and expands into its horizontal non-mobile view when the viewport is at least #grid-float-breakpoint in width. Adjust this variable in the Less source to control when the navbar collapses/expands. The default value is 768px (the smallest "small" or "tablet" screen).

I'm trying to use Semantic-UI sidebar .. But it is always displayed an empty space on right in sidebar: See the grey area...
For iPads (landscape) and computers (screens larger than 640px): Show sidebar
For mobiles or ipads (widescape) (screens smaller than 640px): hide and display sidebar menu
But it is always displayed an empty space when the screen is larger than 640px.
The sidebar has a width of 101px, but seeing the css is calculating how 260px.. in chrome dev tools transform: translate3d(260px,0,0);

When I inspect this example from bootstrap, I find that the margin-bottom in navbar does not separate the navbar and the container.
That's because the navbar is fixed positioned and when you specify some element to be positioned fixed or absolute you are removing that item from document flow hence no effect on subsequent container. Try removing position:fixed on inspect from nav and you will see margin bottom in effect.
When app bar is present, the height of the app bar affects the content on the rest of the page.
For example, if the app bar has a Height of about 25px when ClosedDisplayMode="Minimal", the rest of the content on the page (rootGrid) would have its actual height of Screen Height - 25px. So the app bar is not overlay on page content.
This is visible especially when the content is VerticalAlignment="Center" or Bottom.
Is there any way to avoid this? Something like a ZIndex on the AppBar so that it is displayed over the page content and not trimming it on the bottom side of the screen.
It is possible to tell the renderer that the whole "window" should be used when rendering and not just the visible part. By calling Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().SetDesiredBoundsMode(ApplicationViewBoundsMode.UseCoreWindow) the renderer will include the areas beneath the chrome of the window (ie the system tray on top of the screen and the app bar at the bottom). The chrome will always be on top of whatever is rendered from xaml.
ApplicationView is documented here.
If you don't want the system tray on the top of the screen to overlap the content, you'll have to compensate with a margin on the root container of your visible xaml.
I'm confused as to why the navbar does not collapse at its default breaking point of 768px.
In bootstrap's own example the navbar does not collapse at 768px.
I'm having a problem with this on my own website, and went and tested on bootstraps examples.
I tested bootstraps example page here in this screen emulator. I also tested on a real ipad. Both do not collapse at 768px.

Bootstrap navbar collapse at viewport width 767px, this means your window width is 781px. If your viewport width reaches 768px or any higher value, your navbar will be displayed normally like you see it on any desktop.
Width viewport 767px
Width viewport 768px or higher
You probably was confused by the window width, anyways, if you want to display the viewport and window size like i did in those screenshots, you need web developer addon for firefox, you can also see it in the screenshot, all you need to do is to press on that Resize button and pick Display Window Size but it also has other cool options like View Responsive Layouts or Resize Window.
Hope this helps.
I have a relative div above a fixed one which acts like a navigation bar.
I want to be able to scroll past the relative div before the fixed div starts having to scroll here is my website.
as you can see from just scrolling on the site the sidebar doesn't work as intended.
Try using JavaScript to detect the scroll position of the window and then change the CSS to start scrolling like a fixed div.
Another tip, the the fixed div which contains your projects on the home page lays over your footer when you scroll to the bottom.
Use JavaScript to detect if the user is at the bottom of the page or not and then set the CSS of it to have a margin from the bottom of the page.
Hope I helped.
