I am using addthis as a vertical toolbox with the popup to be displayed on hover in a fixed element.
But when scrolling, the popup is displayed somewhere else. I tried using configs of offset top and left, but there were of no use. Is there any solution for this ???
DEMO here ----> http://jsfiddle.net/vaakash/QzjxR/1/embedded/result/
I tried using the code using jQuery and fairly satisfied my needs. So. here i used the on "mousemove" event to position the popup and it did worked.
$('.addthis_button_compact, .addthis_bubble_style').mousemove(function(e){
$('#at15s').css({
'top': e.pageY - 200 ,
'left': e.pageX - 200
});
});
Apparently there is no fix, according to the AddThis people.
This happens because we don't
recalculate the position of the DIV
after the menu is invoked. What I
would do is disable the compact menu
and set the button to only use the
expanded (full) menu, which is auto
centered.
So change <a class="addthis_button_compact"></a> to <a class="addthis_button_expanded"></a>

I ran into a similar situation where I had a div that dynamicly changed from normal to fixed positioning based on the scroll position (it was a sticky menu halfway on the page).
In the end I fixed it with this code:
// begin Fix for the AddThis menu positioning..
$(".sharing").bind("mouseenter", function (e) {
var isSticky = $(".sharing").hasClass("sticky");
var buttonPos = $(".addthis_button_compact").offset();
addthis_config.ui_offset_top = isSticky ? buttonPos.top - 9 : 0;
});
// config for the AddThis menu positioning, needs to be in the global scope..
var addthis_config = { ui_offset_top: 0 }
See AddThis menu offset for help on the addthis_config parameter.

Using w3css with a pinned navbar (ie enclosed in a with class w3-top) how can I know the height of the navbar (which will vary with screen size) so I can leave this much space at the top of my non-pinned content so the navbar doesn't overwrite content?
My best solution so far is to duplicate the navbar in javascript and insert that at the top of the page without the w3-top class so that there is a hidden element which is always the same size at the top of the page.
...
<div id="pinned_nav" class="w3-top">
<ul class="w3-navbar w3-light-grey w3-border">
<li>
...
<script type="text/javascript">
//Duplicate the nav without pinning it to the top - this means that the other content will adjust to height of pinned nav
var nav = document.getElementById("pinned_nav");
var nav_copy = nav.cloneNode(true);
nav_copy.classList.remove("w3-top");
nav.parentElement.insertBefore(nav_copy, nav);
</script>
...
Since this seemed less error prone than just copy and pasting the HTML block.
But it's still rather clunky and I just wondered if there was a simpler way I was missing.
Other questions like this one which are not w3css specific suggest using a fixed margin to skip a pinned toolbar but I can't see how to determine this margin height with a responsive navbar.
You could use a Javascript script to get the height and append it however you want to use it.
function getHeight() {
var nav = document.getElementById("pinned_nav");
var nav_height = nav.offsetHeight; //append this var where you need to.
alert(nav_height);
};
window.onload = getHeight();
window.onresize = getHeight(); //edit, added for if you resize the page
#pinned_nav {
height: 100px;
/*as example */
background-color: red;
}
<div id="pinned_nav" class="w3-top"></div>

Added resize event subscription.
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.
I am using jQuery-UI Tabs vertically at my site and was having no issues until I started loading content in the tab panels and found that the parent tab panel div does not grow with the content, e.g. tab "Static Info". I can "fix" the issue by setting the parent div class CSS to overflow: auto, which then creates a vertical scrollbar on the parent div. However, I would really prefer if the parent div would just grow with the child content. I did try a couple of clearfix options, including:
$( ".tabs" ).tabs().addClass( "ui-helper-clearfix" );
when intializing the document, but none of the clearfixes made any difference. As I was seeking solutions, I did try adjusting the heightStyle and tab refresh to see if either of those would make a difference. What I found was that this did nothing:
$( ".tabs" ).tabs({ heightStyle: "fill" }); I also tried "content" and "auto" with also no luck.
However, when I tried the alternative as documented at api.jquery.com/tabs:
var heightStyle = $( ".tabs" ).tabs( "option", "heightStyle" );
$( ".selector" ).tabs( "option", "heightStyle", "fill" );
the tabs layout completely broke. The content was all there, but the ul list was at the top of the page with no tabs, followed by all the panel content. I got the same result with:
$( ".tabs" ).tabs( refresh );
I did verify that my jQuery UI in general was working (e.g. I tried
$( ".tabs" ).tabs({ event: "mouseover" }); which worked fine.
This seems like it should be simple, but I've reached a relative dead end with CSS, and I don't understand what is going on with the jQuery- why it breaks with heightStyle and refresh. Any ideas or advice on getting my content to behave itself are very much appreciated... thanks!
Adjust the following from:
#tabs-left > div {
height: 35em;
}
to:
#tabs-left > div {
min-height: 35em;
}
See the following post for a picture highlighting my question and a potential solution:
CSS overflow-y:visible, overflow-x:scroll
However, this strategy breaks when you actually move the scrollbar. In the suggested implementation (position: fixed;), the tooltips display next to child div in its position pre-scroll. So, as you scroll new child-divs into view, the tooltips begin falling off the bottom of the page.
See here for a demo of the bug: http://jsfiddle.net/narcV/4/
Any ideas how I can make the tooltips display next to the child div at all times?
I ended up implementing this using javascript, using the getPos function from this question.
The end product looks like:
var scrollPanel = ...;
var tooltip = ...;
function nodeHovered(e) {
var hovered = e.srcElement;
var pos = getPos(hovered);
pos.x += hovered.offsetWidth;
pos.y -= scrollPanel.scrollTop;
tooltip.style.setProperty('left', pos.x);
tooltip.style.setProperty('top', pos.y);
}
Basically, I calculate where on the page the node is currently displayed (taking into account the scrollbar position), and manually place the tooltip in the right spot on the page.
Too bad there's no elegant/CSS way to do this, but at least this works.
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.
