Fixed and relative elements within a div - javascript

I'm trying to position a fixed element WITHIN a div (not the whole page) in my website.
I want the navigation (deadspin, gawer, awl, other) to be fixed within the writing section so that even when user scrolls, the nav is still there. But currently it's fixed for the whole page.
As you can see on my test page, the navigation is fixed the way I want it to be.
I tried messing around with position:relative/position:fixed for the #small-box-links but that doesn't help.
.home_writing {
display: block;
position: relative;
background: rgba(50, 50, 50, 0);
height: 1000px;
text-align: left;
}
#small-box-container {
border: 1px solid black;
background: rgba(10, 200, 10, 0);
width: 980px;
height: 800px;
overflow: auto;
}
#small-box-links {
position: relative;
margin-left: 700px;
height: 25px;
margin-top: 10px;
}
<div id="small-box-container">
<div id="small-box-links">
deadspin |
gawker |
the awl |
other
</div>
<div style='overflow:hidden; width:980px;'>
<div style='overflow:scroll; width:988px'>
<div id="small-box1" class="small-box">
<h2>deadspin</h2>
<h3>How Pat Summitt Ruined The Best Thing About Women's Basketball</h3>
<!-- etc. for other boxes -->
I found this related question and yet when I try top / left, etc., the element is still fixed to the page, not writing div. (I tried making the parent element, .home_writing, relative but this doesn't fix my issue.)
(On another note, I can't figure out why my Playfair in the paragraphs doesn't look like the sidebar navigation. It's styled the same way).

position:fixed always uses the viewport as the frame of reference, so you can’t use that here.
But the solution is rather simple - use position:absolute instead to position the navigation inside a container element that has position:relative (and a fixed height), and then have the content as a sibling inside that container as well, with fixed height and overflow:auto for that element:
<div style="position:relative; height:800px;">
<div style="position:absolute; top:0; …"> [link link link] </div>
<div style="height:800px; overflow:auto;">
Lorem ipsum, dolor sit …
</div>
</div>

Marquee-like horizontal scroll without scrollbars?

I have seen both overflow scrolling with no scrollbars and Hide scrollbar for mobile devices while keeping the scroll ability ; unfortunately, both of these suggest a solution with position: absolute; and I think that I cannot really apply that to my problem.
The code in this example renders this:
Basically, the red outline boxes are divs of class .myBox, with a fixed width. These divs are side-by-side, in a container that is horizontally centered inside its container div. The top part is reserved for titles, which may be long. I'd like the titles to be rendered as on the right side one - but if they have focus, then I'd want the titles to scroll left-right with either keyboard arrow buttons, mouse wheel - or (also for mobile) dragging left and right.
Of course, since the right box's title has overflow: hidden;, there is no possibility to scroll. If I leave the scrollbar visible (overflow-x: scroll;) as on the left box, then the title is not visible at all (and I cannot scroll anyways).
So is it possible somehow to allow scrolling in the title parts of these boxes in this way (sort of like a marquee scroll behavior, but manual)?
Bonus question: is there a sort of a JavaScript library (or even better, a plain CSS solution), that would allow something similar - except, if the text is too long, it is truncated and ellipsis is added (so, instead of "My even longer" it should show "My even lon..." at start), then as you drag right to left, it also calculates ellipsis at start and at end - and when you come to the right end, it takes away the right ellipsis?
The example code is:
.mainHolder {
font-size: 14px;
border: 2px solid #999;
text-align: center; /* centers the span */
}
.centerer {
border: 2px solid #555;
display: inline-block; /* makes the span have the same width as its div contents*/
margin: 0;
padding: 0;
}
.myBox {
width: 8em;
border: 2px solid #F55;
border-radius: 0.5em;
display: inline-block; /* enables two myBox side-by-side */
}
.heading {
height: 1.25em;
border-radius: 0.25em;
background-color: #94B6F7;
overflow: hidden;
overflow-x: scroll;
}
/*just as example, remove the scroller of box2*/
#box2 .heading {
overflow-x: hidden;
}
<div class="mainHolder">
<span class="centerer">
<div id="box1" class="myBox">
<div class="heading">
My very long title
</div>
<div class="data">
Data: 1
</div>
</div>
<div id="box2" class="myBox">
<div class="heading">
My even longer title
</div>
<div class="data">
Data: 2
</div>
</div>
</span>
</div>

How to scroll beyond fixed position elements on a page with TOC without using JS?

Any ideas how to fix this problem: On a page with TOC (table of contents) with links pointing to hashtags within the same page, when the browser scrolls down other fixed position elements hide it. The browser should scroll further down to avoid being hidden by the fixed elements.
Fiddle to demonstrate this problem: https://jsfiddle.net/fcro6mth/ Click Section One or Section Two - the browser scrolls down to it but its hidden by the fixed header
Solution with JS: https://jsfiddle.net/fcro6mth/1/
Can you think of any solution that doesn’t involve JS?
Code from JS fiddle:
HTML:
<header>
This is the fixed position header
<nav>
Section One
Section Two
Section Three
</nav>
</header>
<div class="body">
This is the body.
<section id="section1">This is section one</section>
<section id="section2">This is section two</section>
<section id="section3">This is section three</section>
</div>
CSS:
section {
background: lightgrey;
margin: 20px 0;
padding: 20px 10px;
height: 300px;
}
header {
background-color: grey;
position: fixed;
top: 0;
padding: 10px;
width: 100%;
box-sizing: border-box;
left: 0;
color: white;
}
.body {
margin: 70px 10px 0 10px;
}
JavaScript:
$("nav a").click(function (event) {
var $target = $(event.currentTarget),
$scrollToTarget = $($target.attr("href")),
$header = $("header"),
prop = {
scrollTop: $scrollToTarget.offset().top - $header.outerHeight(true)
},
speed = 1000;
$('html, body').animate(prop, speed);
});

Nice example to make hidden anchors for offsetting your sections.
Updated version of your fiddle:

Solution
I wrapped your sections in div-wrappers gave them the IDs, padded them down and pulled them back up with a negative margin.
This results in the exact same appearance, but the links do what you want them to do.
Example:
HTML:
<div id="section1" class="wrapper">
<section >This is section one</section>
</div>
CSS:
.wrapper {
padding-top: 50px;
margin-top: -50px;
}
I have struggled with this issue a lot in designing a webpage with a combined banner / navbar of about 300px fixed at the top of a page full of short items linked to by anchor links from the website's home page.
The problem I have found with the "margin-top: -XXpx; padding-top: XXpx" approach is that the invisible padding overlaid the preceding item, meaning that active content (ie. links) were blocked. I overcame this by applying positioning to the anchored elements and setting the z-index so that the first item was on top of the stack with each subsequent item lower in the stack - like this:
CSS
.anchored-element {
padding-top: 300px;
margin-top: -300px;
position: relative;
}
HTML
<div class="anchored-element" style="z-index: 99">FIRST ITEM</div>
<div class="anchored-element" style="z-index: 98">SECOND ITEM</div>
<div class="anchored-element" style="z-index: 97">THIRD ITEM</div>
... etc
This provided a fix that worked for me across Firefox, Safari and Chrome on my desktop, and on my iOS devices. I hope this helps others tackle this very frustrating issue in bootstrap!

bigvideo.js - stack DIVs over and under bigvideo container

So I've started playing around with bigvideo.js (which is built on top of video.js) and it works fine for the basic usage of having a fixed background video over the whole screen. I have also managed to show it inside of a div.
My problem though, is that I can't seem to stack other DIVs with other content over or under the bigvideo.js container div, and I can't seem to figure out how to solve this.
My HTML:
<div style="float: left; width: 100%; height: 300px;">
<h1>hi there</h1>
</div>
<div style="float: left; width: 100%; height: 500px;" id="intro-video-container">
</div>
JS firing up bigvideo:
$(function() {
var BV = new $.BigVideo({container: $('#intro-video-container'),useFlashForFirefox:false});
BV.init();
BV.show('intro.mp4',{ambient:true});
});
So the video container div ALWAYS gets stuck up to the left top of the body, no matter if I try to force it down with margin-top, or place divs before it, etc.
Any ideas?
Update, here is an illustration of what I kind of what to achieve:
Try to use container div (so called wrapping) in your page where you will place the desired content (as on the plugin's example page):
CSS
.box {
background:#444; background:rgba(0,0,0,.6);
padding:20px;
border-radius:5px;
margin-bottom:20px;
}
.main {
position:relative;
margin:50px 50px 440px 220px;
min-width:300px;
-webkit-transition-duration:0.6s;-moz-transition-duration:0.6s;-ms-transition-duration:0.6s;-o-transition-duration:0.6s;transition-duration:0.6s;
}
.dimmed {
color: #ccc;
}
#big-video-wrap {
height: 100%;
left: 0;
overflow: hidden;
position: fixed;
top: 0;
width: 100%;
}
HTML
<div id="big-video-wrap"></div>
<div class="main">
<div id="overview" class="box">
<h1>BigVideo<span class="dimmed"><small>.</small>js</span></h1>
<h2>Simple Ambient Video Example</h2>
</div>
</div>
JavaScript
$(function() {
var BV = new $.BigVideo({container: $('#big-video-wrap'),useFlashForFirefox:false});
BV.init();
BV.show('intro.mp4',{ambient:true});
});
EDIT:
Now, it is more clear what you are trying to achieve, the simplest solution is to include an iframe on place of the div, which points to your full-screen video page.
I.e. create page video.html with all initializations and plug-in includes, then use it as source of your iframe on main page. Your iframe can be styled to match the desired dimensions (for example 100% width and 300px height).

"float" a DIV to bottom of parent DIV not working. (Using Pos: rel, Bottom 0 etc)

Trying to get a DIV to "float" to the bottom of the div its in. I've got the position set to relative on the parent div and kid, and bottom to 0 on the kid; but it still just sits at the top in the middle.
Parent DIV:
.detailsContainer
{
width: 100%;
height: 30%;
overflow: hidden;
position: relative;
background-color: blue;
}
Kid DIV
.obutton
{
text-align: center;
font-weight: bold;
width: 80%;
height: 29px;
background:rgba(204,204,204,0);
position:relative;
bottom: 0;
display: inline-block;
color: #666;
}
Current actual setup:
<div class="detailsContainer">
<a href="javascript:unhide(\'BookDetails'.$row->BookID.'\');">
<div class="detailview"><b>Book Details<br></a></div>
<div id="BookDetails'.$row->BookID.'" class="hidden">
<table>
<tr><td>Total Stock </td><td>'.$row->TotalStock.'</td>
<td>Current Stock</td><td>'.$row->CurrentStock.'</td></tr>
<tr><td>Awards </td><td>'.$row->Awards.'</td>
<td>Film</td><td>'.$row->Film.'</td></tr>
</table>
</div>
';?>
<br><center><a href = "javascript:void(0)"
onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">
<div class= "obutton feature2">Reserve Book</div></a></center>
<div id="light2" class="white_content"></div>
<div id="fade" class="black_overlay"></div>
</div>
Its kind of a lot to post for this, but want to make sure nothing is interfering that you guys might spot. It jumps out of php near the bottom, I'll post the entire article if you think the issue might be else where.
I tried to make a jsfiddle of it, but there is so much php and variables that by time I gutted it, it'd just be 2 normal divs, having lost its uniqueness and the issue will probably have been deleted.
Thanks -Tom
.obutton position needs to be absolute... for bottom to work the way you're intending.

Position badge over corner of image automatically

I have a layout where images "float" within a certain area. The layout looks like this:
The source like this:
<div class="free_tile">
<a class="img_container canonical" href="/photos/10">
<img class="canonical" src="http://s3.amazonaws.com/t4e-development/photos/1/10/andrew_burleson_10_tile.jpg?1303238025" alt="Andrew_burleson_10_tile">
<!-- EDIT: I am aware that I can put the badge here. See the edit notes and image below. -->
</a>
<div class="location">Houston</div>
<div class="taxonomy"> T6 | Conduit | Infrastructure </div>
</div>
The CSS looks like this (in SCSS):
div.free_tile { width: 176px; height: 206px; float: left; margin: 0 20px 20px 0; position: relative;
&.last { margin: 0 0 20px 0; }
a.img_container { display: block; width: 176px; height: 158px; text-align: center; line-height: 156px; margin-bottom: 10px; }
img { margin: 0; border: 1px solid $dark3; display: inline-block; vertical-align: middle; #include boxShadow;
&.canonical { border: 1px solid $transect; }
}
.location, .taxonomy { width: 176px; }
.location { font-weight: 700; }
.taxonomy { line-height: 10px; font-size: 10px; text-transform: uppercase; height: 20px; overflow: hidden; }
}
div.transect_badge { height: 20px; width: 20px; background: url('/images/transect-badge.png'); }
So, basically the images are sitting vertically-aligned middle and text-aligned center, and they have a maximum width of 176 and max height of 158, but they're cropped to maintain the original aspect ratio so the actual top corner of each image falls differently depending on which image it is.
I have a badge that I'd like to put in the top corner of certain images (when the image is "canonical"). You see the style for this above (div.transect_badge).
The problem, of course, is I don't know where the top corner of the image will be so I can't hardcode the position via CSS.
I assume that I'll need to do this via jQuery or something. So, I started with a jQuery method to automatically append the badge div to any canonical images. That works fine, but I can't figure out how to position it over the top left corner.
How can this be done? (ideally using just HTML and CSS, but realistically using JS/jQuery)
--EDIT--
Here's the problem: The image is floating inside a container, so the corner of the image might fall anywhere inside the outer limits of the container. Here's an example of what happens if I try to use position:absolute; top:0; left:0 inside the same container the image is bound by:
It took some tryouts, but here it is: the size independent image badge positioner.
HTML:
<div class="tile">
<span class="photo">
<img src="/photos/10.jpg" alt="10" /><ins></ins>
</span>
<p class="location">Houston</p>
<p class="taxonomy">T6 | Conduit | Infrastructure</p>
</div>
CSS:
.tile {
float: left;
width: 176px;
height: 206px;
margin: 0 20px 20px 0;
}
.photo {
display: block;
width: 176px;
height: 158px;
text-align: center;
line-height: 158px;
margin-bottom: 10px;
}
a {
display: inline-block;
position: relative;
line-height: 0;
}
img {
border: none;
vertical-align: middle;
}
ins {
background: url('/images/badge.png') no-repeat 0 0;
position: absolute;
left: 0;
top: 0;
width: 20px;
height: 20px;
}
Example:
In previous less successful attempts (see edit history), the problem was getting the image vertically centered ánd to get its parent the same size (in order to position the badge in the top-left of that parent). As inline element that parent doesn't care about the height of its contents and thus remains to small, but as block element it stretches to hís parent's size and thus got to high, see demonstration fiddle. The trick seems to be to give that parent a very small line-height (e.g. 0) and display it as an inline-block. That way the parent will grow according to its childs.
Tested in Opera 11, Chrome 11, IE8, IE9, FF4 and Safari 5 with all DTD's. IE7 fails, but a center-top alignment of the photo with badge at the right position isn't that bad at all. Works also for IE7 now because I deleted the spaces in the markup within the a tag. Haha, how weird!
EDIT3: This solution is very similar to my original solution. I didn't really look at your code much so I should have noticed this earlier. Your a tag is already wrapping each image so you can just add the badge in there and position it absolute. The a tag doesn't need width/height. Also you must add the badge image at the beginning of your a tag.
Demo: http://jsfiddle.net/wdm954/czxj2/1/
div.free_tile {
width: 176px;
height: 206px;
float: left;
}
a.img_container {
display: block;
margin-bottom: 10px;
}
span.transect_badge {
display:block;
position: absolute;
height: 20px;
width: 20px;
background-image: url('/images/transect-badge.png');
}
HTML...
<a class="img_container canonical" href="/photos/10">
<span class="transect_badge"></span>
<img class="canonical" src="path/to/img" />
</a>
Other solutions...
In my code I'm using SPAN tags so simulate images, but it's the same idea. The badge image, when positioned absolute, will create the desired effect.
Demo: http://jsfiddle.net/wdm954/62faE/
EDIT: In the case that you need jQuery to position. This should work (where .box is your container and .corner is the badge image)...
$('.box').each(function() {
$(this).find('.corner')
.css('margin-top', ( $(this).width() - $(this).find('.img').width() ) / 2);
$(this).find('.corner')
.css('margin-left', ( $(this).height() - $(this).find('.img').height() ) / 2);
});
EDIT2: Another solution would be to wrap each image with a new container. You would have to move the code that you use to center each image to the class of the new wrapping container.
Demo: http://jsfiddle.net/wdm954/62faE/1/
$('.img').wrap('<span class="imgwrap" />');
$('.imgwrap').prepend('<span class="badge" />');
Technically you can just add something like this to your HTML though without using jQuery to insert it.
Use an element other than <div>, e.g. <span> and put it inside your <a> element after the <img> element. Then, give the <a> element position:relative; and the <span> gets position:absolute; top:0px; left:0px;. That is, if you don't mind the badge also being part of the same link - but it's the easiest way. Also, the reason for using <span> is to keep your HTML4 valid, <div> would still be HTML5 valid, however.
I did find one solution using jQuery. I don't prefer this because it noticably impacts page loading, but it is acceptable if nothing else will work. I'm more interested in NGLN's idea which seems promising but I haven't entirely figured out yet. However, since this thread has picked up a lot of traffic I thought I'd post one solution that I came up with for future readers to consider:
Given this markup:
<div class="free_tile">
<a class="img_container canonical" href="/photos/10">
<img class="canonical" src="http://s3.amazonaws.com/t4e-development/photos/1/10/andrew_burleson_10_tile.jpg?1303238025" alt="Andrew_burleson_10_tile">
<span class="transect-badge"></span>
</a>
<div class="location">Houston</div>
<div class="taxonomy"> T6 | Conduit | Infrastructure </div>
</div>
Same CSS as in question except:
span.transect-badge { display: block; height: 20px; width: 20px; position: absolute; background: url('/images/transect-badge.png'); }
Then this jQuery solves the problem:
$(function() {
$('img.canonical').load( function() {
var position = $(this).position();
$(this).next().css({ 'top': position.top+1, 'left': position.left+1 });
});
});
Like I said, though, this incurs noticeable run-time on the client end, so I'd prefer to use a non JS solution if I can. I'll continue to leave this question open while I test out and give feedback on the other solutions offered, with hopes of finding one of them workable without JS.
