I have two sticky navbars, the first white one from Wordpress with its own sticky function, and the black one below is html/css-only (no bootstrap), and it has a strange movement on mobile, it's hard to explain so let me show you:
When I first load the page, it looks good like this:
But when I scroll down, even if just a little bit, the black navbar kind of bounces suddenly and very quickly and makes the content "jump". I have no idea why this is happening since there is no bug when loading the webpage from a computer! It's only a matter of mobile phones. :S
jQuery(window).scroll(function () {
if (jQuery(window).scrollTop() > 0) {
jQuery('#navbar_reservas').addClass('navbar-fixed');
}
if (jQuery(window).scrollTop() <= 0) {
jQuery('#navbar_reservas').removeClass('navbar-fixed');
}
});
CSS
.navbar-fixed {
top: 60px;
z-index: 1000;
position: fixed;
width: 100%;
}
HTML
<div id="navbar_reservas">
<div id="reservas_left">
<div class="nav-item_reservas" id="inner_reservas_left">

<br /><span id="totalprice">0,00€</span>

<div class="dropdown-content_reservas" id="myDropdown">
<ul id="dropul" class="unoul">

From what I can see you only add the position: fixed when scrollTop is not 0. That will create a new stacking context when the class is applied. That means it'll no longer be "visible" to the elements around it in terms of positioning. And as such the content below it will jump up to fill the gap.
If you know the height of the navbar already, there is a really simple solution:
When the navbar do not have the navbar-fixed class, apply position: absolute on it so it's always in its own stacking context. Then add the height of the navbar as top padding/margin to the content below it.
If you do not know the height:
You'll need to do the same as above, but calculate the height of it with JavaScript on load. If it changes height on say resize or you have some dynamically changing content, you'll need to make sure to update the height used for the above method when those events happen.
If you can work with relatively new code:
There is a CSS property for all this! position: sticky combined with top: 0 Will make the navbar stick to the top of the screen when it otherwise would scroll up behind the viewport.
However, browser support isn't very impressive:

I have a simple html code where I have a left menu. I want to scroll content on click of menu within the same page. Also I don't want to scroll menu.
The problem is, I am using AngularJS so compiler is confused between routing and segment logic.
Here is my menu:
<div class="container">
<div style="float: left;width:150px;">
<ul class="list-group">
<li class="list-group-item">overview</li>
<li class="list-group-item">Clinical features</li>
<li class="list-group-item">Diagnosis</li>
<li class="list-group-item">Testing laboratories</li>
<li class="list-group-item">Result interpretation</li>
</ul>
</div>
<div class="col-md-10" id="clinical">
<div class="row">
<div class="col-md-2">Result interpretation</div>
<div class="col-md-10">
<p style="text-align: right;">Back To Top</p>
</div>
</div>
<hr>
<p>Hey this is just to test.</p>
</div>
</div>
This is not a problem specific to AngularJS or anything else. It's just a tiny CSS problem:
You're aligning your menu using float: left, which will cause it to appear on the left border but it won't follow you down when scrolling (as you've noticed).
The solution is pretty simple, just attach your menu in a different way. There are many different ways to do this, also depending on whether you're using any JavaScript library (like Bootstrap), but the most simple approach would be pinning the menu using CSS:
.menubar {
/* A fixed alignment will ignore scroll bar positions */
position: fixed;
/* Stretch the bar by forcing offsets and a width */
top: 0;
left: 0;
bottom: 0;
width: 150px;
}
Last but not least you'll have to move your content so it's not hidden by the menu bar (which would otherwise overlap):
.content {
padding-left: 150px; /* of course this could use positioning as well */
}
You can try the whole thing in this jsFiddle.
From your question it's not clear whether you're also looking for soft scrolling, but for that you'll most likely want some additional JavaScript library - or you could just use some library that provides everything for you (including menu bar CSS etc.), like Bootstrap or UI Kit.
My website consists of a navigation bar (class .nav-primary), a widget box (id #mw-panel) and an article. Recently, I tried to move the widget box up to the top, by applying the following changes to my CSS file:
.mw-panel{top: 50px;}
The problem with this option was, that my element was fixed to a specific position. Instead I wanted the widget element to be exactly 100px under the menu bar (and moving when I am scrolling down the page). Instantly, I knew that JavaScript would be the correct way to solve this problem.
Because I had no success, I asked the StackOverflow community, which helped me a lot.
The JavaScript code in the JS section of the attached code snippet, was partially done by me, but it does not work as it should.
Can someone explain me what I need to change to get this JS code working? Again, #mw-panel has to be positioned exactly 100px beneath .nav-primary.
var menu = document.getElementsByClassName("nav-primary")[0];
var widget = document.getElementById("mw-panel");
var difference = widget.offsetTop - menu.offsetBottom;
if (difference > 100) {
document.getElementById("mw-panel").style.top = (menu.offsetBottom + 100) + "px";
}
.content .entry {
margin-top: 40px;
padding-bottom: 400px;
}
<body class="full-width-content">
<link rel="stylesheet" id="child-theme-css" href="http://vocaloid.de/wp-content/themes/Vuturize/style.css" type="text/css" >

There's No such property as offsetBottom. Redo your code ONLY considering offsetTop + offsetHeight to get bottom number.
Example:
var menu = document.getElementsByClassName("nav-primary")
var TrueOffset=menu[0].offsetTop+menu[0].offsetHeight;
You're getting the error because there is no offsetBottom property.
Do console.log(menu) in chrome to see the objects available properties
**Update:
Add this to your css:
.mw-panel{
position: absolute;
}
Here it is in action

After re-reading your question, I missed one key detail: you're trying to do this JavaScript. This is your problem.
If I understand correctly, you have three items: a nav, an article, and a widget box. You want the widget box to stand 100px below the nav, and then move with the page when you scroll.
if this is the case (if not, correct me), then there's only a few things you need to do:
Keep your nav the way it is. Good job here.
I'm assuming you want the widget next to the article (on the left?). So you'll need to make two columns (some sort of containers, each height: 100%). Your widget container will have the property position: fixed; and the article will have position: static; (or relative, you decide).
Each container will have a width, you might choose 30% for the widget container and 70% for the article, for example.
Now you have two columns, one will move with the page as you scroll.
Here are some links to get you started:
Best Way to do Columns in HTML/CSS
https://css-tricks.com/guide-responsive-friendly-css-columns/
http://www.456bereastreet.com/lab/developing_with_web_standards/csslayout/2-col/
for example ,this is a js code: befor scrolling
<div style="left: auto; position: relative;">
<ul>
<li></li>
<li></li
</ul>
</div>
after scrolling
<div style="left: 375.6px; position: fixed; top: 0px;">
<ul>
<li></li>
<li></li
</ul>
</div>
then I enlarge the page 120% ,this div style does not follow it becoming 120%? I mean in IE7
Actually your Style will be working, as I think you have applied CSS in pixels, now please tell me how can a css be applied to a control which change it's position on enlarging it!! You need to use "%" instead of "px", pixels will make the things static, if I am applying CSS using my Laptop and I try to run the same application on my Desktop whose Screen is much wider than Lapi then how can things may work similarly on both the Screen's!! So, just try to apply CSS in % and not in px.
My new home page has a position fixed header at the top of the page and the container holding the content scrolls up underneath that.
Theres a text box that on the left which I want to fix so that its always visible when the rest of the content scrolls up.
The container which holds all copy is positioned relative with auto margins so that it sits central onscreen.
I haven't been able to find code online that will enable me to keep the div in the container and therefore obey the central alignment of the container, but be fixed below the header while the rest of the container scrolls.
Any ideas how I could do this please? Is it javascript or CSS?
Any help would be greatly appreciated.
I have tried putting the text box and header in one div together, but then the content gets pushed down. I read that floating should work but doesn't. I have looked at 'sticking' the text box to the bottom of the header div, but can't seem to get that to work.
See www.broadleydesign.co.uk/test3
NB. Apologies if the header isn't stuck at the top in IE on your machine; I haven't sorted any workaround yet. There should be a white space at the top with the logo and top links in. The images should scroll up underneath that. I haven't got a pc to check it!
You need to move the ul into the head section and give it position: fixed css, not position: absolute. See my example below using your code:
<div id="header-cont">
<h1><img src="images/background/logo.jpg" alt="Broadley Design, Graphic design and image production"></h1>
<div id="home">
<ul id="titles">
<li>home
</li>
<li>profile
</li>
<li>contact
</li>
</ul>
<ul id="sideheads">
<li class="firstsub">
<img src="images/headings/broadley_design_co.png" alt="">
</li>
<li><span class="bold"> Diane Broadley</span>
</li>
<ul class="sublistwider">
<li>A freelance graphic designer specialising in print, providing a one
<br>to one service, design solutions and production to ensure that your business gets into the hands of the people who
<br>matter to you.</li>
<li>Working both directly with small businesses, designers and publishers
<br>in the South West.</li>
</ul>
</ul>
</div>
</div>
Give the position:fixed css property to the target div.
<div class="fixed">Fixed Text</div>
and style it as:
.fixed {
position: fixed;
top:10px;
left:10px;
}

I have suggested a jQuery(javascript) plugin HERE
There are various JQuery plugins that can help you do what you want.
This functionality is called as "sticky scroll"
Working in a hackathon and we are having an issue with our phone mockup. We want to anchor the text stream to the bottom: seems like a great opportunity for position: absolute...right? Well that makes it so that our scrolling doesn't work. Right now it is anchored to the top, positioned relative, and scrolling does work.
Try clicking the "I said..." button a few times. Ideally those buttons should be anchored (along with the text boxes that appear) to the bottom.
This is the temporary URL:
http://gotinto.com/text/
AND a PERMANENT JS Fiddle URL:
http://jsfiddle.net/Qyn7V/
Here is the simple HTML:
<div class="convoPhone">
<div class="phoneDisplay">
<div class="convoCont">
<div class="actualConvo">...(the actual text convo goes here)...</div></div></div></div>
Any solutions? We would be open to javascript, CSS, any combination. Thanks in advance!
Have you tried position: fixed? Observing your link, as a proof of concept, something like this should do:
<div class="addLine" style="position: fixed; bottom: 60px; width: 290px;">
Edit:
Put three place holder conversations as place holders with visibility: hidden (this ensures they occupy space).
<div class="convoCont">
<div class="actualConvo" style="">
<div class="invisibleFirst">
<div style="visibility: hidden;" class="textInputCont isaid"><div class="author">Me:</div><textarea class="isaid"></textarea><div class="delete">Remove</div></div>
<div style="visibility: hidden;" class="textInputCont isaid"><div class="author">Me:</div><textarea class="isaid"></textarea><div class="delete">Remove</div></div>
<div style="visibility: hidden;" class="textInputCont isaid"><div class="author">Me:</div><textarea class="isaid"></textarea><div class="delete">Remove</div></div>
</div>
</div>
<div class="addLine" style="position: fixed; bottom: 60px; width: 290px;">
<div class="isaid textLine">I said...</div>
<div class="tsaid textLine">They said...</div>
</div>
<br class="clear">
</div>
Then for each of the first 3 real entries, remove one of the place holders. If you want more precision, you can replicate the same place holder effect with padding-top on actualConvo. Just reduce the padding-top by a fixed value until it bottoms out at 0. If you want to make the buttons scrollable, just removed the styling and apply the padding-top at a higher DOM level.
I ended up positioning the buttons absolute, then using a bit of jquery/javascript to make a minimum height. Thanks for your help everyone!
var contH = $('.phoneDisplay').css('height');
if($('.convoCont').css('height') < contH) {
$('.convoCont').css('height',contH);
}
