Dynamically created elements are hiding Bootstrap popover - javascript

This is a pretty straight forward problem. It only occurs in Safari. I have a popover on an element. This is all well and good so far. I have an interactive element that dynamically adds a div to the DOM. Once this element is added, any popover that occurs in the same position is behind the dynamically added element (vision is obscured).
EDIT: Just to be clear the dynamic element is an iframe. I attempted adding a static iframe to the page and the problem still occurs in Safari. Is there some sort of crazy auto iframe styling that happens in Safari?
EDIT2: Maybe code examples will help show that I have tried z-index
css for dynamic element
.active_tv_screen{
position:absolute;
left:0;
top:0;
width:100%;
height:100%;
border-radius:5px;
z-index:3 !important;
}
custom styling for popover to try and force it in front of dynamic element
.popover {
z-index: 1001 !important;
position:absolute;
max-height:500px !important;
}
Reminder: this problem is Safari speicific

set the 'z-index' of the element you want to remain visible higher than the 'z-index' of the other elements. don't forget you'll need to specify a position: absolute | relative | etc...

Here is the fix - add ?wmode=opaque to the end of the embed url (the src attribute) and it will be fixed. The problem is the new flash player.

Bring element on top of modal backdrop

I am trying to build a guide functionality for my application. As a part of this functionality, it is expected that a tooltip is shown next to the target HTML element and this target element is brought on top of modal backdrop that appears together with the tooltip.
The problem is that after significant effort I still cannot make HTML element show on top of the modal backdrop. Simple tricks like z-index: 10000 !important; position: relative do not help. Also changing parent elements' z-index by disabling it in Firefox Developer Tools (and leaving z-index: 10000 !important; position: relative for the target element that is supposed to be on top of the modal backdrop) does not help.
HTML of the application is quite complex with many elements. But I want to be able to "highlight" any given element by bringing it on top of the modal overlay knowing only its id. Is there an easy way to do that with JavaScript/React?
Hopefully there is a way to do this without modifying the DOM, which would be highly preferable.
UPD: Code demo - press hat button to show guide/tooltips
Remove the z-index from .form-wrapper and apply relative position with z-index for the targetted elements.
I did this by adding
d.classList.add("tooltip-active-element");
to App.js#77
Also added the class to the css file:
.tooltip-active-element {
position: relative;
z-index: 2;
background: red;
}
and removed the z-index value from other classes, the key one being the .form-wrapper class.

scroll and position: fixed inside overflow: scroll div

I have a position: fixed div besides a div with long text inside a div with overflow: scroll. I want the text to scroll even if my cursor is hovering over the fixed div (which is the normal behavior when the window would be the scrolling element).
I made a fiddle: http://jsfiddle.net/jM2Eh/1/
I basically want the text to scroll while scrolling hovering over the red box.
UPDATE: I am using Twitter bootstrap in this particular case and updated the fiddle accordingly.
If JavaScript is needed for that, that would also be ok.
UPDATE2: I also tried this solution, but that causes weird flickering effects:

Have you tried using padding-left on your text node instead of using two columns?
http://jsfiddle.net/j5BLm/15/
.text {
padding-left: 50%;
}
Another possible solution is to use pointer-events: none if you don't care about IE:

How to set a target="_blank" in a DIV tag?

Got a page that displays some buttons (background images, etc) and they are all clickable. What I want this specific button to do is open the target page in another browser tab using *target="_blank"*. The way it is setup as the href in a div I cannot do this. Any ideas on a work around for this?
<div class="dashboard_navbutton" href="Home/RequestRedirect" style="background-image: url('#Url.Content("~/Content/images/Form_button.png")');">
<p>Insert witty text here</p>
</div>
Just make that div an a and add display:block; to the style.
EDIT: Ensure that your chosen DOCTYPE supports the use of p inside an a element. More generally, it should use the computed style for display rather than the tag name to determine if an element is inline or block in terms of having one in the other. I believe the HTML5 one is fine: <!DOCTYPE html>.
trap the onclick event for the div, call a javascript function, have the function openthe window.
html snippet
onclick="opennewwin()"
function opennewwin(){
var awindow = window.open(loc, "blank", "height=500px,width=500px");
}
I was trying to dynamically add divs that would also function as links.
This was my solution using CSS.
First the container needs relative positioning.
.container {position: relative;}
Next, the link needs to fill the container.
.container a {position: absolute; width: 100%; height: 100%; top: 0; left: 0;}
Like I said, I dynamically assembled the div, but the html would look something like this:
<div class='container'>[some other content]</div>
The container must be position relative, otherwise the position absolute link fills its first position relative ancestor (probably the whole viewport).
Of course, you can add styling to the div or the link. Note, I was using a position: sticky nav-bar, and I had to set it's z-index high in order to avoid collisions with the div buttons.
Pros: whatever styling and targeting you set for your links will apply. Good 'style': doesn't put a block element inside an inline (should avoid browser issues, though I haven't thoroughly tested it). Does not require any other languages or frameworks.
Cons: Not as simple as Niet's answer, but shouldn't be Doctype dependent.

Place something on top of a drop down (z-index doesn't work)

How can I place a html element (e.g. div or img) on top of a select with it's options using javascript, jquery and/or css? Z-index doesn't work in any browsers.
You will need to use an iframe "shim" with a higher z-index. You can then put you element "on top" of that.
another way would be to show/hide the drop-down whenever you hide/show the div/img or use an iframe.
If you use z-index and you want to layer one item on top of another without showing or hiding them, the best way will be to set absolute positioning on the top layer or possibly both DOM elements.
#item1, #item2{
position: absolute;
left:10px;
top:10px;
z-index:1;
}
#item2{
z-index:2;
}

adjusting height of div based on internal div

I have a set of divs like so:
<div id="textArea">
<div id="text"></div>
</div>
CSS properties:
#textArea {
height: auto !important;
min-height: 2em;
overflow: hidden;
}
#text{
display: none;
}
I'm filling in the div with the id of "text" with error messages coming back from a POST request using jQuery. The size of the data coming back is not static, but my problem is that the div is not adjusting.
I am basically trying to mimic the Ruby on Rails default flash message that will push divs further down the page with a dynamically adjusted div.
I think you are simply doing too much - A div should automatically expand to fit the text content inside it, unless you have a specific rule saying otherwise. Do you have a rule that specifies a height for all divs? Is that why you have the height: auto !important here? Are you using a reset stylesheet? Something external to these rules is affecting your divs.
Hope that this points you the right way.
Div's should update height and width automatically unless otherwise told to. What is your jQuery code to update the div? What are you using to reveal the div to the browser (since it's currently set to display:none)? Have you tried using firebug to inspect the elements?
