How to overlap Bootstrap Navbar on Carousel?

Question

I am working on a mock up and I want a full-screen carousel with the nav bar links sitting on top of the images. Currently, the navbar is clear and when I scroll down on the image/slider it's full screen. How can I have the nav bar lay on top of the carousel on initial load? I am using BS4 alpha also.

Currently: current position of nav bar on load

Wanted: wanted position of navbar on load

Code:

html,body {
  height:100vh;
}
.carousel, .item, .active {
  height:100vh;
}
.carousel { 
  top: 0;
}
.carousel-inner {
  height:100vh;
}
.carousel-inner img {
  margin: auto;
}

Solution

As per you html file try adding the below code. Explanation when you make Carousel position:absolute with top:0, it goes on top , overlapping all html components, now to make it full screen we use 100% width. here the navbar is not visible now it is their but not visible it is behind the carousel, so to make it visible we use z-index:9;

.navbar{
 z-index:9; 
}
#fullCarousel{
  position:absolute;
  width:100%;
  top:0;
}

i hope you understand.

try using position:absolute in navbar

[KyleJayMaxwell]

@MukeshRam there is no change when I add that in the css.

[KyleJayMaxwell]

When i add the absolute positioning to the carousel with "top: 0;" the carousel goes to the top left corner.

[Admin]

try this: position: absolute; left: 0px; top: 0px; z-index: -1;

[KyleJayMaxwell]

The carousel is going to the top left corner and not extending the full width when this happens. With just absolute and top 0.

[KyleJayMaxwell]

That code worked for me. Would you care to elaborate as to why? Also the navbar z index code isn't needed. Also the width and position can be applied to both the id and class and still work.

you can use z-index:9 in navbar or you can also use z-index:-1 in carousel
