Sticky navigation element jumps during scroll

In Firefox especially, I've run into an issue I can't figure out how to fix.
On the following page, when scrolling down the page jumps several times - mainly on smaller screens where the page doesn't have its full size displayed. You can replicate this issue by making your browser smaller than the page so you have to scroll.
It's on this page: http://www.nucanoe.com/frontier-accessories/
If I disable the position:fixed on the navigation selector, it fixes the issue - but we need the navigation to be sticky. Is there a solution to fix this? I'm thinking we may need to use jQuery somehow.
Thanks in advance!
After seeing you asking for help on another answer, I will try and explain more clearly for you.
The Problem
Your problem is when you add position:fixed to the navigation bar, it removes it from its place and sticks it at the top of the page. This is why the rest of your content jumps up - because the navigation bar is not where it was anymore.
How To Fix
You can get around this by wrapping your navigation element in a new div - let's call it nav-wrapper - and set its height to the same as your navigation element. These are known as placeholder elements. This new wrapper and your original navigation bar must always be the same height for the 'jump' to disappear.
<div class="nav-wrapper" style="height:80px;"> <-- add this
<div class="your-original-nav" style="height:80px"></div>
</div> <!-- add this
Now, when you set the navigation bar to fixed and it disappears to the top, the new wrapper we created with the same height keeps the page's content the same. When the fixed class has been removed, it sits back in the wrapper again, without pushing the content down.
A Suggestion
From what I can see on your site, there will be a big gap where the navigation bar was until the new fixed navigation reaches that point and covers it. What you want, is a little jQuery to figure out where to make the navigation fixed and where to hide it. I'll explain:
// cache the element
var $navBar = $('.your-original-nav');
// find original navigation bar position
var navPos = $navBar.offset().top;
// on scroll
$(window).scroll(function() {
// get scroll position from top of the page
var scrollPos = $(this).scrollTop();
// check if scroll position is >= the nav position
if (scrollPos >= navPos) {
$navBar.addClass('fixed');
} else {
$navBar.removeClass('fixed');
}
});
You may want to add further functionality to this example, as it is very, very basic. You would probably want to recalculate the offsets on window resize as one addition.
A Demo
This is a little demo which might help you - I was bored and feeling helpful :)
Made it this way now: Added an element before the nav:
<div class="nav-placeholder"></div>
And the jquery:
<script type="text/javascript">
$(document).on("scroll",function(){
if($(document).scrollTop()>150){
$(".nav-placeholder").height($(".nav").outerHeight());
} else {
$(".nav-placeholder").height(0);
}
});
</script>
When I scroll down to 150 the placeholder gets the height of the nav, when i scroll up again I set it's height to 0.
Here is a fiddle: https://jsfiddle.net/herrfischerhamburg/562wu62y/
You need to have a placeholder when your nav goes from relative to fixed.
Therefore you need to make a new div.
jQuery(".nav").wrap('<div class="nav-placeholder"></div>');
jQuery(".nav-placeholder").height(jQuery(".nav").outerHeight());
jQuery(".nav").wrapInner('<div class="nav-inner"></div>');
Remember to change ".nav", "nav-inner" and "nav-placeholder" to your desire.

I solved the problem differently so on firefox as you can see in logs it scroll up itself so to stop this scrolling I made simple statement
$(document).ready(function () {
var header = $('#left-menu');
var offset = header.offset().top;
var up = true;
$(window).scroll(function () {
var scroll = $(window).scrollTop();
console.log(scroll + ' ' + offset )
if (scroll >= offset) {
header.addClass('sidebar-sticky');
if (up){
$(window).scrollTop(offset);
up=false;
}
} else {
up=true;
header.removeClass('sidebar-sticky');
}
});
});
that solution work for me when I can't specify height of div's I use.

Set div style to avoid control displacement

I have three divs which i set float:left side by side.
In all these three divs, i have one textbox, one checkbox and one button. I have set checkbox set to visible = false initially. On click of button i am setting the checkbox visibility to true. by doing this div position gets adjust to left and causing layout problem. How can i set div style to avoid this layout displacement problem.I want there should not be any control displacement while show and hiding the checkbox I am newbie in css.
Here is my fiddle link Link
How about using the css property visibility? The visibility attribute allows the element to be hidden, but leaves the space where it would have been. For more information about it, read here.
DEMO: http://jsfiddle.net/Lppme028/22/
CSS
#txt
{
visibility: hidden;
}
JavaScript
$(document).ready(function () {
$("#btn").click(function (){
$("#txt").visibilityToggle();
})
});
jQuery.fn.visibilityToggle = function() {
return this.css('visibility', function(i, visibility) {
return (visibility == 'visible') ? 'hidden' : 'visible';
});
};

Bootstrap popover - move it to the left/right side

I want to relocate my bootstrap popover in the left side, i.e. I want to move the whole popover in the left side, while the white arrow would stay in one place.
I would like to have the effect which is on google.com website, when you click blue icon you see popover but its content is relocated while the white arrow is located under the user.
I know that I can use something like this:
.popover {
top:0 !important;
margin-top:10px;
}
Unfortunately, it relocates the whole popover altogether with white arrow.
What I have now (popover is on the right side and there's no place between screen edge and my popover)
What I want to have (small distance between popover and monitor's edge):
“I want to change the position of content of this popover so that this
arrow will be placed further on the left„
When the popover is shown the arrow position is calculated in Tooltip.prototype.replaceArrow based on width/height and placement. You can force a specific position with this CSS :
.popover .arrow {
left: 90px !important; /* or 45% etc */
}
But that will affect all popovers. Popovers is injected and removed to and from the DOM, and there is by default no way to target visible popovers individually. If you want to style the arrow on a specific popover, a workaround is to hook into the shown.bs.popover event, detect which popover that is being shown, and style the arrow for that popover if needed. Example :
.on('shown.bs.popover', function() {
var $popover = $('.popover')[0];
switch ($(this).attr('id')) {
case 'a' : $popover.find('.arrow').css('left', '10px');break;
case 'b' : $popover.find('.arrow').css('left', '40%');break;
case 'c' : $popover.find('.arrow').css('left', '180px');break;
default : break;
}
})
To get this to work, there must be only one popover shown at a time (see fiddle). It can be worked out with multiple visible popovers also, but then we need to add some HTML to the popover content.
see demo -> http://jsfiddle.net/uteatyyz/
As what I have understood so far, you want to achieve the popover to the left of the button.
Please check this Plunker Link
HTML Code:
<div class="pull-right">
<button type="button" mypopover data-placement="left" title="title">Click here</button>
</div>
Angular Code:
var options = {
content: popOverContent,
placement: "bottom",
html: true,
date: scope.date,
trigger: 'focus'
};
I have edited the answer as per the images that you have shown.

redirect a div of a page but I need it redirect animate and scroll in js

I have page xyz.com that has a div id="abc". So I want to redirect to div abc from another page www.xyz.com/#abc.
can you tell me how to get xyz.com/#abc top position in number? I tried in body
var hash_value = window.location.hash.replace('#', '');// get abc
var top = $(hash_value).offset().top;
is not working . I want to redirect xyz.com/#abc will animate and scroll to #abc .
I have many div like #abc so I need something dynamic js code like
var top = $(this.hash).offset().top;
$('html, body').animate({scrollTop: top}, 500, function() {});
its working when I put
var top=1300;
1300 is the top position of #abc ;I want top position get dynamically for #add #bar
dynamically getting #abc is not possible then is it possible to pass value with
click here
Thanks in advance.
You will need javascript. You can do something as scroll. When you load the page, then after that scroll the page 28px down as
$('#abc').scrollTo(28); // scroll 28px down
You will use this function inside $('body').load(function ()
Put
#abc {padding-top:28px; margin-top:-28px;}
in your css.
Fiddle here: http://jsfiddle.net/MrLister/AGzX7/5/
You can test by showing http://jsfiddle.net/MrLister/AGzX7/5/show (normal view) or http://jsfiddle.net/MrLister/AGzX7/5/show#abc (with abc on top, starting below the menu bar).
(Make sure your window is narrow enough to enable #abc to scroll to the top, otherwise you won't see it!)
I agree with Afzaal
$('body').load(function(){
$('#abc').scrollTo(0, 28) // using plain javascript
})
or
$('body').load(function(){
$('#abc').scrollTop(28) // using jQuery
})

page size as screen size and scrollable frame inside

Here's the scenario:
I have an asp.net webpage which displays dynamic data in a gridview.
I'm using a master page to display the header and footer of the page, and this gridview is being displayed inside a div in the contentplaceholder.
The Problem:
What I want is that the size of the page that is displayed remains constant for a user and must be equal to the size of their browser's available display area and the content being visible by scrolling the div.
Sort of like the header and footer remain at the same position and the content inside it is scrollable.
I really don't know how to achieve this.
Any help on the matter is highly appreciated.
Thanks.
Try some jQuery:
function changeHeight(){
var winHeight = $(window).height();
var heightOfHeaderAndFooter = 200px; // change this to what you need
$('#myDiv').height($(window).height() - heightOfHeaderAndFooter);
}
$(window).resize(function() { // changes height with browser window
changeHeight();
});
$(document).ready(function() { // changes height on load of the page
changeHeight();
});
What you want is for your div to use width:auto and to dynamically change the height of it to always keep the footer at the bottom of the page. Also, make sure your div has overflow-y:scroll
Code snippet:
divMain.style.height --> height of div in pixel containing GridView. This div tag also has style setting of style="overflow-y:auto;"
document.documentElement.clientHeight --> height of the working/client area for your display.
document.getElementById("divMain").offsetTop --> height of content prior to divMain.
25 --> this is the height of my additional footer.
The pixel result is the height available for your divMain.
divMain.style.height = (document.documentElement.clientHeight - document.getElementById("divMain").offsetTop - 25) + "px";
Hope this helps.
