Tabindex and overflow:hidden - javascript

I have a problem. I have an Instagram feed by Instagrams API, which pulls image, likes, comments and description. The description under the image is shorted by this css:
#instagram-feed .meta-data p {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
color: #000;
}
I have also added a script which creates links on hashtags, so you can click them directly in the feed.
This works great. Until you are starting to tab the page. Since the text/hashtags is hidden after one row, it is still in the HTML-structure, just not visible.
So what happends when I am tab the the page and get to the Instagram feed is that the tabindex finds the hidden hashtags. But they are invisible. Only the focus frame shows around the hidden hashtags.
tabindex="-1" removes element from tabindex which I want to add to overflowing/hidden links, but I can't do this manually since the description is dynamically created. I need better CSS (If possible) or somekind of jQuery. But I have no idea how.
So my question is, how do I remove hidden links from tabindex? :)
Edit:
Trying this to see what elements is inside or outside the parent:
http://jsfiddle.net/fprm7mgd/8/. The link inside the third paragraph should be red.
On the site the position().left; in the third p is something like 670px, when running console.log. But in reality the a is about 130px right from its parent left side. It seems like position().left; goes from parent div, not from parent p...

The solution is to add... position:relative ... to the paragraphs.
position().left use its offset element, which in this case is <html>. In other words, position().left works exactly as position: absolute in CSS. If the parent is not position: relative it counts from the <html>-element.

"Priority Nav" breaks when div is floated

I'm using the "Priority Navigation" design pattern. For those who aren't quite sure what this is, basically when the viewport width is reduced and there isn't enough space for all the list-items to fix horizontally, they're moved into another nested list so they can still be accessed. This is within a "more" link at the end of the list.
At a basic level, this works fine in my example (below):
http://codepen.io/moy/pen/RrRJBe
The problems I'm having are:
1) Because I have another item alongside the navigation, which is floated (and of unknown width), I needed to set overflow:hidden; on the nav. This means when the width of the container changes, the nav stays alongside the other content rather than dropping onto the next line. It's fixes that ...the problem is it also means the dropdown on the end isn't visible as it's displayed below the navigation and overflow: hidden; is set.
Any alternative (CSS) fixes for this?
2) Another issue is the nav links need to be positioned to the right. No problem, just float the div right, yeah? Unfortunately it doesn't like this and the page almost crashes - must be something to do with the script trying to calculate the widths? As soon as the nav or it's parent is floated, it breaks!
The list-items are floated left so they display horizontally. Instead I tried using display: inline-block and text-align: right;. This positions the text correctly but when there's not enough horizontal space the items either wrap or all collapse into the "more" link rather than one-by-one.

Browser requirements: It's worth noting that my browser support is IE8+, so flexbox is unfortunately out the window. Even if it worked, it would mean that I'd have to find a fix for IE8/9.
Is anyone able to help with this, or maybe there's a plug-in I should take a look at. This script works great when the nav is isolated but as soon as another item is in it's path it becomes a bit tricky. On a previous attempt I got the width of the item which was in the way and subtracted it for the available space. But that isn't that flexible/scalable - but that again, maybe there isn't another way?
Thanks, hope someone can help!
Part 1
You can use clearfix instead of overflow: hidden.
Add the following to the parent element containing nav:
.wrap:before, .wrap:after {
content: '';
display: table;
clear: both;
}
But if you need to support IE8, you can just add element like below to the bottom of the parent element containing nav
html
<div class="clear"></div>
.clear {
clear: both;
}

Bootstrap Collapse over an element

I'm using Bootstrap 3 to make a responsive website. However, I'm making a "portfolio".
You can see the website here as well as my "error".
http://basic-models.com/b/
Scroll down to "Our models" and click on "Informations". When you click on that button, it will collapse a new element below the profile picture of a model.
But that collapsible element is pushing the picture below the element to right for one column.
I guess I don't have to place code here since you can just right click > source code it.
Also, this is my first question on Stack Overflow, so I'm sorry if it is not formatted properly. Thank you for all the help.
You can change the CSS position attribute of the collapsing div to absolute. That way, the element will float over the below item - but you`ll have to apply styles a bit.
Try it like that:
.model-outer div.collapse {
position: absolute;
z-index: 1000;
background-color: white;
width:100%;
left:0px;
margin-top:10px;
}
You see, positioning and styles are not that good, but I assume you can start from there.
Since you are already using Bootstrap, I would suggest you to use default bootstrap dropdown . The problem with current code is that the div which shows the information is not absolutely positioned. So, whenever that div is displayed, it takes up the extra space and breaks the layout of the grid. Bootstrap dropdown uses absolute positioned div and hence it doesn't break the layout. Try using it and it will definitely solve this issue.

How to use angularjs $anchorScroll on div only if div is hidden?

I'm using angularjs to develop a web application. I have several nested div. Each of them correspond to an item that the user can select.
A good example of my div display is in the official angularJs documentation :
http://plnkr.co/edit/qncMfyJpuP2r0VUz0ax8?p=preview
In my code each div have a ng-click="gotoAnchor(x)" event so when I click on a div if it is partially hidden, it pull it up on the page and the user can see all the clicked div.
But I have a header in my page so the first div with an anchor and a click event is not directly at the top of the page. And if I click on the first div, it will scroll and the header won't be visible.
So my question is, is there a way to activate the anchor only if the div isn't fully displayed on the screen ?
If you have an other solution than anchors, I take it.
Thank you in advance.
If I understand your question correctly the issue is that when using $anchorScroll your header is either
a: Being covered up by the div scrolled into frame,
or
b Partially covering up the div that is scrolled into frame.
Either way there are two solutions you should review:
First
make sure you're employing CSS to properly layer your elements, your header (if fixed) should have a z-index that supersedes your divs.
.header { position: fixed; top:0; width: 100%; z-index: 99}
.content { position: relative; margin-top: 10px; z-index: 1;}
REMEMBER Z-index only works on positional elements (See ref)
Second
Employ $anchorScroll.yOffset to make sure your scroll distance is bumped down to compensate for the header height. As seen in the Angular docs, you can use this method in your application:
.run(['$anchorScroll', function($anchorScroll) {
$anchorScroll.yOffset = 50; // always scroll by 50 extra pixels
}])
Update 50 to be the pixel height of your header.
Regarding visibility
There are a few great libraries and directives for checking the visibility of an element - try https://github.com/thenikso/angular-inview as you can specify whether you want to enable an action when only the top, bottom or none of the div is visible.
Note Posistioning the first div correctly on the page will prevent any scroll from being necessary as seen in this plunkr.

CSS positioning full width and height of multiple elements

Good evening gentlemen (and of course ladies),
I'm currently experiencing some problems with CSS and the dynamic positioning of some elements in one big container. And I hoped that anyone of you could probably know the solution for my problem.
Maybe I just start with the explanation, which I will split in three parts to make it easier to understand. In the end of this post, there are two links, one for the steps to visualize them and one for the example jsfiddle for step two.
Step one:
There is one div.container which has the height 255px and a dynamic width of 33.3%. This container contains two divs: div.left and div.right. The div.left has exactly 150px width, which should bring the div.right to fill up the whole remaining space.
I already tried to solve it this way, which works, but not for the next steps.
.left {
float: left;
width: 150px;
}
.right {
overflow: hidden;
}
Step two: Now, there should be three different elements in the div.right, a h3, span and p element. The h3 and span should just behave like a regular element, and use the space they want to use (like for displaying text). But the p element should take the whole remaining height of the div.right. I achieved this single step by using the code in the jsfiddle link in the end of this post. And it looks really cool, but it's not compatible with the next step. As you maybe already guessed it.
Step three:
As the p.description element contains a description, I want to put as much information into this small element as possible. Therefor, I hoped to use overflow:hidden in combination with text-overflow:ellipsis, but this didn't work. Due to some strange reason, the p.description element was placed right of the h3 and span elements after I added the overflow:hidden style.
And additionally, there is an extra div in the footer of the div.right, which is div.btns. This div contains about 3 plain links and is placed absolutely in the right bottom of div.right, and I only want to have the p.description element to wrap the text around it.
Right now, I doubt, that all of these steps are solvable by only using css. At least, I wanted to have the positioning of the elements with css and the truncating of the text could be done in Javascript.
Is there anybody out there, who has an idea, how I could solve my problem?
Many thanks in advance!

In css: the max-height of the ellipsis in lines(52 & 61) are now 200px,
this can be changed with jQuery if you want to, on window resize or load.
max-height: 200px; /*This value could be changed with jquery*/

How to insert an html element before another without shifting the originals position

I would like to be able to insert an element that a user can navigate (left) to without disturbing what the user currently sees. that is, the new element will be inserted offscreen, to the left, but the currently "focused" element (and the other visible ones) shouldn't be seen to move.
Currently I am doing this using insertbefore, measuring the clientWidth of the new element and subtracting that from the margin of the container element. However, clientWidth is expensive to get, and this method is proving problematic when I add transitions. Is there a cleverer way to do this? I would have thought it's a fairly common problem - insert an element before another without shifting everything else.
You could use some CSS to achieve this. Insert a wrapping div with no height, but overflow: visible, insert the elements you want inside this div:
.wrapper {
height: 0;
overflow: visible;
}
.wrapper div {
margin-left: 100%;
}
