twitter bootstrap navbar fixed top overlapping site - html
I am using bootstrap on my site and am having issues with the navbar fixed top. When I am just using the regular navbar, everything is fine. However, when i try to switch it to navbar fixed top, all the other content on the site shifts up like the navbar isn't there and the navbar overlaps it. here's basically how i laid it out:
.navbar.navbar-fixed-top
.navbar-inner
.container
.container
.row
//yield content
i tried to copy bootstraps examples exactly but still having this issue only when using navbar fixed top. what am I doing wrong?
Your answer is right in the docs:
Body padding required
The fixed navbar will overlay your other content, unless you add padding to the top of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.
body { padding-top: 70px; }
Make sure to include this after the core Bootstrap CSS.
and in the Bootstrap 4 docs...
Fixed navbars use position: fixed, meaning they’re pulled from the
normal flow of the DOM and may require custom CSS (e.g., padding-top
on the ) to prevent overlap with other elements.
As others have stated adding a padding-top to body works great.
But when you make the screen narrower (to cell phone widths) there is a gap between the navbar and the body. Also, a crowded navbar can wrap to a multi-line bar, overwriting some of the content again.
This solved these kinds of issues for me
body { padding-top: 40px; }
#media screen and (max-width: 768px) {
body { padding-top: 0px; }
}
This makes a 40px padding by default and 0px when under 768px width (which according to bootstrap's docs is the cell phone layout cutoff where the gap would be created)
a much more handy solution for your reference, it works perfect in all of my projects:
change your first line from
.navbar.navbar-fixed-top
to
.navbar.navbar-default.navbar-static-top
Just change fixed-top with sticky-top. this way you won't have to calculate the padding.
And it works!!
The solution for Bootstrap 4, it works perfect in all of my projects:
change your first line from
navbar-fixed-top
to
sticky-top
Bootstrap documentation reference
About time they did this right :D
#Ryan, you are right, hard-coding the height will make it work bad in case of custom navbars. This is the code I am using for BS 3.0.0 happily:
$(window).resize(function () {
$('body').css('padding-top', parseInt($('#main-navbar').css("height"))+10);
});
$(window).load(function () {
$('body').css('padding-top', parseInt($('#main-navbar').css("height"))+10);
});
This issue is known and there's a workaround in the twitter bootstrap site:
When you affix the navbar, remember to account for the hidden area
underneath. Add 40px or more of padding to the <body>. Be sure to add
this after the core Bootstrap CSS and before the optional responsive
CSS.
This worked for me:
body { padding-top: 40px; }
I put this before the yield container:
<div id="fix-for-navbar-fixed-top-spacing" style="height: 42px;"> </div>
I like this approach because it documents the hack needed to get it work, plus it also works for the mobile nav.
EDIT - this works much better:
#media (min-width: 980px) {
body {
padding-top: 60px;
padding-bottom: 42px;
}
}
As I've posted in a similar question, I've had good success with creating a dummy non-fixed nav bar right before my real fixed nav bar.
<nav class="navbar navbar-default"></nav> <!-- Dummy nav bar -->
<nav class="navbar navbar-default navbar-fixed-top"> <!-- Real nav bar -->
<!-- Nav bar details -->
</nav>
The spacing works out great on all screen sizes.
The problem is with navbar-fixed-top, which will overlay your content unless specify body-padding. No solution provided here works in 100% cases. The JQuery solution blink/shift the page after the page is loaded, which looks weird.
The real solution for me is not to use navbar-fixed-top, but navbar-static-top.
.navbar { margin-bottom:0px;} //for jumtron support, see http://stackoverflow.com/questions/23911242/gap-between-navbar-and-jumbotron
<nav class="navbar navbar-inverse navbar-static-top">
...
</nav>
All the previous solutions hard-code 40 pixels specifically into the html or CSS in one fashion or another. What if the navbar contains a different font-size or an image? What if I have a good reason not to mess with the body padding in the first place? I have been searching for a solution to this problem, and here is what I came up with:
$(document).ready(function(){
$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height()) + 1 )+'px'});
$(window).resize(function(){
$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height()) + 1 )+'px'});
});
You can move it up or down by adjusting the '1'. It seems to work for me regardless of the size of the content in the navbar, before and after resizing.
I am curious what others think about this: please share your thoughts. (It will be refactored as not to repeat, btw.) Besides using jQuery, are there any other reasons not to approach the problem this way? I've even got it working with a secondary navbar like this:
$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height())
+ $('.admin-nav').height() + 1 )+'px'});
PS: Above is on Bootstrap 2.3.2 - will it work in 3.x As long as the generic class names remain... in fact, it should work independent of bootstrap, right?
EDIT: Here is a complete jquery function that handles two stacked, responsive fixed navbars of dynamic size. It requires 3 html classes(or could use id's): user-top, admin-top, and contentwrap:
$(document).ready(function(){
$('.admin-top').css({'margin-top':($('.user-top').height()+0)+'px'});
$('.contentwrap') .css({'padding-top': (
$('.user-top').height()
+ $('.admin-top').height()
+ 0 )+'px'
});
$(window).resize(function(){
$('.admin-top').css({'margin-top':($('.user-top').height()+0)+'px'});
$('.contentwrap') .css({'padding-top': (
$('.user-top').height()
+ $('.admin-top').height()
+ 0 )+'px'
});
});
For handling wrapping lines in menu-bar, apply an id to the navbar, like this:
<div class="navbar navbar-default navbar-fixed-top" role="navigation" id="topnavbar">
and add this small script in the head after including the jquery, like this:
<script>
$(document).ready(function(){
$(document.body).css('padding-top', $('#topnavbar').height() + 10);
$(window).resize(function(){
$(document.body).css('padding-top', $('#topnavbar').height() + 10);
});
});
</script>
That way, the top-padding of the body gets automatically adjusted.
use this class inside nav tag
class="navbar navbar-expand-lg navbar-light bg-light sticky-top"
For bootstrap 4
for Bootstrap 3.+ , I'd use following CSS to fix navbar-fixed-top and the anchor jump overlapped issue based on
https://github.com/twbs/bootstrap/issues/1768
/* fix fixed-bar */
body { padding-top: 40px; }
#media screen and (max-width: 768px) {
body { padding-top: 40px; }
}
/* fix fixed-bar jumping to in-page anchor issue */
*[id]:before {
display: block;
content: " ";
margin-top: -75px;
height: 75px;
visibility: hidden;
}
All you have to do is
#media (min-width: 980px) { body { padding-top: 40px; } }
Further to Nick Bisby's answer, if you get this problem using HAML in rails and you have applied Roberto Barros' fix here:
I replaced the require in the "bootstrap_and_overrides.css" to:
=require twitter-bootstrap-static/bootstrap.css.erb
(See https://github.com/seyhunak/twitter-bootstrap-rails/issues/91)
... you need to put the body CSS before the require statement as follows:
#import "twitter/bootstrap/bootstrap";
body { padding-top: 40px; }
#import "twitter/bootstrap/responsive";
=require twitter-bootstrap-static/bootstrap.css.erb
If the require statement is before the body CSS, it will not take effect.
I would do this:
// add appropriate media query if required to target mobile nav only
.nav { overflow-y: hidden !important }
This should make sure the nav block doesn't stretch downpage and covers the page content.
This works and looks good for me.
<body class="pt-5 mt-4">....</body>
I just wrapped the navbar in a
<div width="100%">
<div class="nav-? ??">
...
</nav>
</div>
No fancy hocus pocus but it worked..

Bootstrap 5 (beta) - Navbar partial Override - Sticky Top Not Working
I'm using the BS5 beta and I'm running into an odd problem with the sticky-top class - I'm relatively new to Bootstrap.
USE CASE
I want to customize the .navbar (and dependent classes). I created a complete copy of the navbar partial (not sure if this a best or bad practice, but I have too many changes to do it piecemeal.
I want to use the sticky-top class (the fixed-top class has the same problem)
IMPLEMENTATION
The custom navbar partial is imported after the off-the-shelf navbar partial.
Most of the other overrides are working fine.
ISSUES
Sticky-top only works if either:
I don't use a custom navbar partial - but obviously I don't want to modify the off-the-shelf partial.
I use a custom partial and hard-code the .navbar class position property to sticky (from relative).
So, I can make it work by hard-coding the position property - not the end of the world. But it seems to me that if sticky-top works with the off-the-shelf partial, it should work with the custom version. And I'd like to avoid unnecessary customizations...
Is this a beta bug or am I doing sth really backwards?
NAVBAR PARTIAL
.navbar {
display: flex;
// navbar position should be relative and
// sticky-top helper class should force navbar to be sticky
// this works with the off-the-shelf navbar partial, but not an overridden one
**position: sticky;** // modified - 2021.02.25
padding-top: $navbar-padding-y;
padding-right: $navbar-padding-x; // default: null
padding-bottom: $navbar-padding-y;
padding-left: $navbar-padding-x; // default: null
align-items: center;
flex-wrap: wrap; // allow us to do the line break for collapsing content
justify-content: space-between; // space out brand from logo
#include gradient-bg();
POSITION PARTIAL (not modified)
.fixed-top {
position: fixed;
top: 0;
right: 0;
left: 0;
z-index: $zindex-fixed;
}

Bulma centered navbar mobile issues
I'm creating a navbar for a current project in react (create-react-app). I'm using the Bulma framework for all css-related things. The current problem lies in the navigation bar, the elements of which should together be centered and visible on mobile.
While this isn't possible with Bulma alone, I used some scss modifications I've found to make it somewhat work:
Stylesheets
.navbar-start { // fixes is-expanded on the navbar items
flex-grow: 1;
flex-shrink: 1;
display: flex;
text-align: center;
}
.navbar-item {
border-style: solid;
border-color: black;
border-width: medium;
}
#center-item {
border-right-width: 0;
border-left-width: 0;
}
HTML (navbar only)
<div>
<nav className="navbar is-dark" role="navigation" aria-label="main navigation">
<div className="container has-text-centered ">
<div className="navbar-menu">
<div className="navbar-start">
<Link className="navbar-item is-expanded has-text-weight-semibold is-size-5" to="/">/home</Link>
<Link id="center-item" className="navbar-item is-expanded has-text-weight-semibold is-size-5" to="/visual">/visual</Link>
<Link className="navbar-item is-expanded has-text-weight-semibold is-size-5" to="/about">/about</Link>
</div>
</div>
</div>
</nav>
</div>
Finally, to make this horizontal navbar visible on mobile, I've also modified a bulma variable according to this in the scss file.: $navbar-breakpoint: 0.
In the end, the issue is the following:
This is on an iPhone 7. I haven't been able to reproduce it on desktop Firefox by resizing the window. For further examination, you can use this is the live version of the site: http://51.15.246.99/. I've tried many things in fixing this issue so any help would be appreciated.
The solution to the issue is somewhat hacky. After posting about it on GitHub's issue page for Bulma and after some careful on-device debugging the issue turned out to be caused by this (abridged) css rule in Bulma:
.navbar-menu {
margin-right: -0.75rem;
}
In quoting the creator of the framework "It's to align the navbar container with the other containers. But it should only exist on desktop". It existed on mobile as I've set the navbar-breakpoint to 0. The fix was to just include this in my custom css:
.navbar-menu {
margin-right: 0 !important;
}

Hide header and footer using Custom CSS
I am trying to hide the header and footer from a specific page on my website. I am using a theme I downloaded online. The specific page I am trying to hide is http://ai-home.com/dsme/
I installed a custom CSS plugin so that I can customize the CSS on this page. I inspected the page element and can see that I am most likely trying to hide the
div id="header-space" and div id="footer-outer"
After reading online I think the code should be
.page-id-5321 .site-header, .page-id-5321 .site-footer {
display: none;
}
or
.page-id-5321 .site-header-space, .page-id-5321 .footer-outer {
display: none;
}
When I publish, I do not see any changes to the page. I am not a developer so I want to make this edit as easily as possible without it affecting the rest of my website.
EDIT:
tried some suggestions and was able to fix most of the problem, but now I am stuck with a big grey bar on the bottom but I can't find it via inspect element.
EDIT#2: So the CSS looks like this right now, but still stuck with a grey bar on the bottom
#header-outer { display: none;}
#header-space { display: none;}
#footer-outer { display: none;}
Use the visibility property as hidden. Like [ visibility:hidden ] In your header class/id.
Please try below code for removing header-outer, header-space and footer-outer
.page-id-5321 #header-outer, .page-id-5321 #header-space, .page-id-5321 #footer-outer {
display: none;
}
I think if you use wordpress, in your specific page can use other header or/and other footer.
Change
get_header();
to
get_header('<other header file>');
same with footer
Try it
<div id="header-space" class="hide">xyz</div> and <div class="show" id="footer-outer">abc</div>
csscode:
.hide{display:none;}
.show{display:block;}
If you need to hide a block/section then just add class:hide to HTML OR for showing use class name show like mention above.
Hope it will work. Revert if it is not.
For grey bar solution
#footer-outer #copyright, body {
border: none!important;
background-color: #f8f8f8!important;
}
By changing the color of footer you can use the same background.

Header 'div' not aligned exactly to the top of screen (Simple but frustrating)
I am simply adding a header navbar to an html page.But the problem is its not aligned exactly to the top.There is a small gap between the browser and the navbar.I found a solution as setting margin:0;,but the issue I have is it will only work if I code it as by selecting the whole div... like
*{ margin:0;}
why is that so ?
I found this solution in another stackoverflow question but I cant comment and ask because I have low repuation.He is stating its because of SASS.But how is my code becoming sass because I was using normal simple procedure for CSS coding.
Linked soultion question.(Please check the comments in correct selected question)
Header not touching top of screen
My code :
<html>
<head>
<style>
* {
margin:0;
}
.new {
width:100%;
background-color: blue;
}
</style>
</head>
<body>
<div class="new">New Website</div>
</body>
</html>
Some browser have set user agent stylesheet at "body" tag
For Chrome: body have margin: 8; on body tag, so you will get a small gap between navbar.
You can set
body{
margin: 0;
}
Will solve your problem.
http://jsbin.com/luqoruqewa/edit?html,output
Don't put the margin: 0; on the div. Put it on the body or html tag. Like so:
body{
margin: 0;
}
Don't forget that you can style the html and body tags too! Making them height: 100%; might be of use in the future.
* is the universal selector. It targets all elements. When you state:
* {margin: 0}
You're removing the margin from every element on the page. That works in this case, but it will have side effects that you probably won't want on a page with more content.
Your browser is adding some padding to the body element. As amoyer pointed out, set the body margin to zero and you should be fine.
