I want to make my navbar fixed on the top and push down content when I open the collapse menu like it normally do in static or just nav.

Like this: (https://getbootstrap.com/examples/navbar-static-top/) But I want the navbar to be fixed to top.

I read this before: Navbar-fixed-top pushes content on page up

but adding padding just won't work, please help me solve this xD

My code

CSS & HTML:

/*------------------------------------------------- Hero Image -------------------------------------------------*/

		.calltoaction {
		text-align: center;
		-webkit-user-select: none; /* Chrome/Safari */
		-moz-user-select: none; /* Firefox */
		-ms-user-select: none; /* IE10+ */
		/* Rules below not implemented in browsers yet */
		-o-user-select: none;
		user-select: none;
		}

		.calltoaction h1 {
		text-align: center;
		display: inline-block;
		font-size: 70px;
		/*text-transform: uppercase;*/
		letter-spacing: 2px;
		border: 8px solid #FFFFFF;
		border-radius: 13px;
		padding: 17px 20px;
		color: white;
		font-family: sans-serif;
		font-weight: 900;
		}

		.calltoaction h3 {
		color: #FFFFFF;
		font-size: 29px;
		text-align: center;
		}


		#hero-image {
		height: 870px;
		background: #e8eced url('http://twnateserver.no-ip.org/Pictures/taiwan-taipei.jpg') no-repeat center;
		}

		#hero-image h1 {
		margin: 215px 0 7px 0;
		}

		#hero-image h3 {
		margin: 3% 0 7px 0;
		}


		/*#hero-image a {
		margin: 3% 0 7px 0;
		}*/



/*------------------------------------------------- Hero Image -------------------------------------------------*/

margin-bottom: 0px;

Add padding top to the body equal than the height of the navbar. If this solution doesn't work show more code or fiddle of youre project. – Germano Plebani
It did not work. Original code added. I know it must be my own stupid problem but i just cannot find out why. Thx for helping – Nate Lo
See this fiddle with youre code jsfiddle.net/Ldrgt5df If you want the background image go under the nav this works, otherwise say what you want :) – Germano Plebani
It was still the same to me, I cannot see background image being pushed down. I want the whole page being pushed down when the collapsed navbar extended. Like this: ( getbootstrap.com/examples/navbar-static-top ) – Nate Lo
MMM you mean when you open the collapsed menu, all content pushed down? If you want this isn't possible. – Germano Plebani

If padding isn't working for you, try this for <nav>:

nav.navbar-fixed-top {
  position:fixed;
  top:0;
}

and then the below for <body>:

body::before {
  display:block;
  content: '';
  height:60px; /* or whatever */
}

Add

body {
    min-height: 2000px;
    padding-top: 70px; /*70px nabar height*/
}

see bootstrap example

I want to make my navbar fixed on the top and push down content when I open the collapse menu like it normally do in static or just nav.

I recently met with such a requirement and below jquery helped.

/* Jquery to push to content down for fixed boostrap navbars in mobile displays 
 * Replace 400px with desired value througout
 */

jQuery(function($){

$("#navbar-collapse li.expanded.active.dropdown").on("click",function(){
if($("button.navbar-toggle").attr("aria-expanded") == "true")
 $(this).trigger("data-attribute-changed");
});

$("#navbar-collapse li.expanded.active.dropdown").on("data-attribute-changed",function(){
if(!$(this).hasClass("open")){
 var dropdown_height=$(this).children(".dropdown-menu").height();
 var navbar_collapse_margin = parseInt($("#navbar-collapse").css("margin-top")) + dropdown_height;
 navbar_collapse_margin = navbar_collapse_margin + "px";
    $("#navbar-collapse").css("margin-top",navbar_collapse_margin);
   }
   else{
    $("#navbar-collapse").css("margin-top","400px");
   }
});

$(window).on("resize",function(){
if($("button.navbar-toggle").attr("aria-expanded") == "true")
 $("#navbar-collapse").css("margin-top","0px"); // Reset margin on resize
});

$("button.navbar-toggle").on("click",function(){
if($("button.navbar-toggle").attr("aria-expanded") == "true")
 $("#navbar-collapse").css("margin-top","0px"); // Dealing with regular displays
else
 $("#navbar-collapse").css("margin-top","400px"); 
});

});

navbar has a min-height of 50px as per this rule on line 4169 of bootstrap.css 

.navbar {
  position: relative;
  min-height: 50px;
  margin-bottom: 20px;
  border: 1px solid transparent;
}

so for the div after navigation menu have a margin-top of at least 50px and it should work fine..
