Changing z-index of youtube iframe - css

In React, I have a parent component and a child component. The parent shows an iframe, returning this jsx:
<div className={cx("col-md-6", classes.BWrapper)}>
<iframe className={classes.Iframe} width="100%" src="https://www.youtube.com/embed/OVoFzu-vH4o" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>
Then the child component handles some asynchornous code and while doing that it changes the state to loading and showing a spinner
return (
<div className={globalStyles.Card}>
<div className={cx("card-header", globalStyles.CardHeader)}>
<ul className="nav nav-tabs card-header-tabs">
{formTypesJsx}
</ul>
</div>
<div className="card-body">
<div className="tab-content">
<div role="tabpanel" className="tab-panel" id="signup-form">
{this.props.loading && (<div><Backdrop show/><Spinner/></div>)}
I guess it's not ideal to show a spinner in the child component that is supposed to cover in gray the elements of the parent, but I set the spinner elements with z-index and it's working fine except the iframe window is still appearing on top of the spinner.
Spinner css:
.Center {
position: fixed;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
z-index: 200;
}
I tried different stuff including giving the spinner z-index: -1 , opacity: .99 and also tried to give the iframe an absolute positioning and a higher z-index than the spinner, and giving the spinner relative position
Is there something I'm missing? Why is only the iframe appearing on top of the spinner?
Thanks in advance

Vue transitioned element not showing after transition is complete

I'm trying to animate an element to full browser height when the user clicks on the top bar. The animation works, but once the (enter) animation is finished the container jumps back to zero height, while it's supposed to stay until the user clicks the close button.
How do I make the container stay 100vh when the animation is finished?
I tried adding height: 100vh; on the element, but by doing that the transition animation stopped working. (by removing the height, the animation works but the element disappears)
Not sure if it matters, but I changed v-if into v-show and also added a key on the container, but that didn't seem to make a difference.
Here's a link to my code. And to view the animation.
<!-- AboutMeComponent.vue -->
<template>
<div>
<div v-show="!extended" class="small-container" #click="extended = !extended">
<h4>
CLICK ME
</h4>
</div>
<ExtendTransition>
<div v-show="extended" key="1" class="main-container">
<div class="icon-container">
<a v-show="extended" href="#" #click="extended = !extended">
<font-awesome-icon icon="times"/>
</a>
</div>
</div>
</ExtendTransition>
</div>
</template>
<!-- ExtendTransition.vue -->
<template>
<transition appear name="extend" mode="out-in">
<slot></slot>
</transition>
</template>
<style lang="scss">
.extend-enter-active,
.extend-leave-active {
transition: 3s;
}
.extend-enter-to,
.extend-leave {
height: 100vh;
}
.extend-leave-to {
height: calc(20px + 1vw);
}
.extend-enter {
height: calc(40px + 3vw);
}
</style>
A transition only is applied while the transition is playing. Once the transition finished, all transition classes are removed. This means that your element must have the CSS you want it to have after the transition is finished. You can then use the transition classes to set the initial state and define the transition to get to that point, and from that point to the initial state.
The easiest way to solve this problem is by making ExtendTransition.vue the only component that worries about the transition, and using a wrapper that wraps the thing you want to extend.
<template>
<transition appear name="extend" mode="out-in">
<div class="extend-transition-wrapper" v-show="extended">
<slot></slot>
</div>
</transition>
</template>
<script>
export default {
props: {
extended: {
type: Boolean,
default: false
}
}
};
</script>
The only thing you then have to do is to set the default state of your wrapper:
.extend-transition-wrapper {
height: 100vh;
will-change: height;
position: relative;
}
In your ABoutMeComponent.vue you then use a prop to show and hide the content:
<ExtendTransition :extended="extended">
<div class="main-container">
<div class="icon-container">
<a v-show="extended" href="#" #click="extended = !extended">
<font-awesome-icon icon="times"/>
</a>
</div>
</div>
</ExtendTransition>
And finally you set .main-container to always have a height of 100%. Since we set the wrapper to have position: relative, this will force the main container to become the height of that element.

Fix element inside scrollable area

I just finnished of creating the basis for my chat... I just got around detecting the scroll positioning of the user and want to use this information to make a "Scroll down button" if the chat is not fully scrolled down and a message is recieved. I used position: sticky and that worked all well... But when i got around to testing it across web browsers it did not work very well seems to be very short term to go with it then. What kind of positioning can I use to achieve the same results cross platforms?
<div id = 'chatlogs'>
<div class='chatContainer self'>
<div class = 'imgContainer'>
<img src='displayProfilePicture.php?user_id=$id'>
</div>
<div class='content'>
<div class = 'message'>
". $extract['msg'] ."
</div>
</div>
The chatlogs is filled with multiple of the shown small "chat objects" and no i want for the popup to be placed at the bottom verticaly and center horizontaly in the chatlogs.
<span onclick = 'doScroll();' class = 'fa fa-arrow-down'></span>
</div>
position: sticky just works in chrome for now
To make the button fixed in the scroll you need to let him outside the content scrollable
<div class="scroll-wrapper">
<div class="scroll">
blah blah
</div>
<span onclick = 'doScroll();' class = 'fa fa-arrow-down'></span>
</div>
and with css you can use position absolute to let it fixed
.scroll-wrapper{
position: relative
}
.fa-arrow-down{
position: absolute;
left: 50%; // center horizontally
transform: translateX(-50%); // center horizontally
-webkit-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-ms-transform: translateX(-50%);
bottom: 10px;
}

How to overlap component?

I have the following angular component lets call it child-component
<div>
<a-component-tag></a-component-tag>
<router-outlet></router-outlet>
</div>
which is itself being rendered into another router-outlet like this
<div>
<top-component></top-component>
<router-outlet></router-outlet>
<div>
I would like the component that is rendered in the first router-outlet above to either render below a-component-tag or cover a-component-tag, depending on the user clicking a maximize, minimize button. It shouldn't cover anything but a-component-tag (i.e. it should not cover top-component).
This component is defined by
<div id="thiscomp" [ngclass]="max?cover:minimize">...</div>
I tried to define these two classes as
.cover{
position: absolute;
top: 0;
left: 0;
z-index:100;
}
.minimize {
margin-top:30px;
}
but the cover class is not working: Some of the subcomponents in the thiscomp div are rendered above some stay minimized.
You're trying to change the order in which two DOM elements appear -- there are better techniques than absolute positioning available for that.
The javascript in this example is just for demo; the work is being done in the CSS:
document.getElementById("example").onclick = function() {
document.getElementById("container").classList.toggle('flip');
}
#container {display: flex; flex-direction:column}
#container.flip {flex-direction: column-reverse}
<div id="container">
<div class="componentA">Component A</div>
<div class="componentB">Component B</div>
</div>
<button id="example">Toggle</button>

Bootstrap Modal sitting behind backdrop

So I'm having nearly the exact same problem as #Jamescoo was but I think that my issue is coming from the fact that I have already positioned a couple of DIVs to create a sliding nav panel.
Here's my exact setup replicated: http://jsfiddle.net/ZBQ8U/2/
BONUS: Feel free to grab the code for the sliding panel if you'd like :)
The z-indexes shouldn't conflict and their values would show that they are stacking correctly, but visually they are not.
Once you click the 'Open Modal' button the <div class="modal-backdrop fade in"></div> covers everything! (you'll have to re-run the code to reset it)
I don't know quite how to remedy this one...Any ideas?
Just move the entire modal outside of the rest of your code, to the very bottom. It doesn't need to be nested in any other element, other than the body.
<body>
<!-- All other HTML -->
<div>
...
</div>
<!-- Modal -->
<div class="modal fade" id="myModal">
...
</div>
</body>
Demo
They hint at this solution in the documentation.
Modal Markup Placement
Always try to place a modal's HTML code in a top-level position in your document to avoid other components
affecting the modal's appearance and/or functionality.
In my case, I could fix it by adding css for the .modal-backdrop
.modal-backdrop {
z-index: -1;
}
Although this works, form controls still seem to appear above the backdrop, clicking anywhere dismisses the modal, but it doesn't look great.
A better workaround for me is to bind to the shown event (once the page is loaded) and to correct the z-index property.
$('.modal').on('shown.bs.modal', function() {
$(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
});
In this case, if you are OK with changing the DOM on modal shown:
$('.modal').on('shown.bs.modal', function() {
//Make sure the modal and backdrop are siblings (changes the DOM)
$(this).before($('.modal-backdrop'));
//Make sure the z-index is higher than the backdrop
$(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
});
Although the z-index of the .modal is higher than that of the .modal-backdrop, that .modal is in a parent div #content-wrap which has a lower z-index than .modal-backdrop (z-index: 1002 vs z-index: 1030).
Because the parent has lower z-index than the .modal-backdrop everything in it will be behind the modal, irrespective of any z-index given to the children.
If you remove the z-index you have set on both the body div#fullContainer #content-wrap and also on the #ctrlNavPanel, everything seems to work ok.
body div#fullContainer #content-wrap {
background: #ffffff;
bottom: 0;
box-shadow: -5px 0px 8px #000000;
position: absolute;
top: 0;
width: 100%;
}
#ctrlNavPanel {
background: #333333;
bottom: 0;
box-sizing: content-box;
height: 100%;
overflow-y: auto;
position: absolute;
top: 0;
width: 250px;
}
NOTE: I think that you may have initially used z-indexes on the #content-wrap and #ctrlNavPanel to ensure the nav sits behind, but that's not necessary because the nav element comes before the content-wrap in the HTML, so you only need to position them, not explicitly set a stacking order.
EDIT
As Schmalzy picked up on, the links are no longer clickable. This is because the full-container is 100% wide and so covers the navigation. The quickest way to fix this is to place the navigation inside that div:
<div id="fullContainer">
<aside id="ctrlNavPanel">
<ul class="nav-link-list">
<li><label>Menu</label></li>
<li><span class="fa fa-lg fa-home"></span> Home</li>
<li><a><span class="fa fa-lg fa-group"></span>About Us</a></li>
<li><a><span class="fa fa-lg fa-book"></span> Contacts</a></li>
</ul>
</aside>
<div id="content-wrap">
...
</div>
</div>
DEMO HERE
None of the answers worked well enough for me.
The problem appeared to lie where the modal windows needs to be outside of the body.and it is not best
So this code done the job just prefectly:
$('.modal ').insertAfter($('body'));
$('#product_' + product_id + ' .modal ').insertAfter($('body'));
I'm wary of moving the modal content outside its original context: other JS or styles might depend on that context.
However, I doubt there are any scripts or styles that require a specific context for the backdrop.
So my solution is to move the backdrop adjacent to the modal content, forcing it into the same stacking context:
$(document).on('shown.bs.modal', '.modal', function () {
$('.modal-backdrop').before($(this));
});
It's only a slight deviation from jacoswarts' solution, so thanks for the inspiration!
Try remove the backdrop, if you don't realy need it (data-backdrop= "false"):
<div class="modal fade" data-backdrop="false" role="dialog" id="my-modal" aria-labelledby="modal-title">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h3 class="modal-title" id="modal-title">No Backdrop</h3>
</div>
<div class="modal-body">
<p>
Look! No backdrop here!
</p>
</div>
<div class="modal-footer">
<button class="btn btn-default" data-dismiss="modal">Cancel</button>
<button class="btn btn-primary">Ok</button> </div>
</div>
</div>
</div>
I know it is late, I encountered the same problem but I had to hack it out as below;
.modal-backdrop {
/* bug fix - no overlay */
display: none;
}
.modal{
/* bug fix - custom overlay */
background-color: rgba(10,10,10,0.45);
}
I was fighting with the same problem some days... I found three posible solutions, but i dont know, which is the most optimal, if somebody tell me, i will be grateful.
the modifications will be in bootstrap.css
Option 1:
.modal-backdrop {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 1040; <- DELETE THIS LINE
background-color: #000000;
}
Option 2:
.modal-backdrop {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: -1; <- MODIFY THIS VALUE BY -1
background-color: #000000;
}
Option 3:
/*ADD THIS*/
.modal-backdrop.fade.in {
z-index: -1;
}
I used the option 2.
In my case one of parents of my modal was animated and had this
.animated {
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;
z-index: 100;
}
The blocker here is animation-fill-mode: both;. I could not just move modal outside, so the solution was to override 'animation-fill-mode' to animation-fill-mode: none;. Animation still worked fine.
Another resolution for this problem is to add z-index: 0; to .modal-backdrop class in your bootstrap-dialog.css file if you don't want to modify bootstrap.css.
if we cannot delete backdrop and/or we have component framework such angular or vue we cannot move modal to the root. i did this trick: put my custom modal-backdrop container(with aditional class) as sibling for modal-dialog container and added some css
<div bsModal #moneyModal="bs-modal" class="modal fade" tabindex="-1" role="dialog">
<!-- magic container-->
<div class="modal-holder modal-backdrop" (click)="moneyModal.hide()"></div>
<div class="modal-dialog modal-sm" role="document">
<div class="modal-content">
<div class="modal-body">
....
</div>
</div>
</div>
</div>
and css
.modal-backdrop{z-index: -1}// or you can disable modal-backdrop
.modal-holder.modal-backdrop{z-index: 100}
.modal-holder + .modal-dialog {z-index: 1000}
You could use this :
<div
class="modal fade stick-up disable-scroll"
id="filtersModal"
tabindex="-1"
role="dialog"
aria-labelledby="filtersModal"
aria-hidden="false"
style="background-color: rgba(0, 0, 0, 0.5);" data-backdrop="false"
>
....
</div>
Adding style="" and data-backdrop false would fix it.
For those using ASP.NET MVC,
Needing to move the modal div just before the </body> tag but can't do it because you are using a Layout page
Define a section in you _Layout.cshtml file just before the body tag, eg:
... some html in layout page ...
#RenderSection("bottomHTML", required: false)
</body>
</html>
Then in your view
#section bottomHTML
{
<div class="modal fade" id="myModalID" role="dialog" tabindex="-1" aria-labelledby="demo-default-modal" aria-hidden="true">
... rest of the modal div HTML ...
}
This way, the modal HTML will be rendered before the body tag and the modal now should be displayed correctly..
If you use JQuery, you can use the appendTo() to append the modal to a specific element, in this case, the , in most case, a simple one line can move your modal on top of the backdrop regardless where your modal div's position
$("#myModal").appendTo("body");
here's the reference of the JQuery appendTo function:
http://api.jquery.com/appendto/
I updated it to your fiddle
http://jsfiddle.net/ZBQ8U/240/
Just remove the backdrop, insert this code in your css file
.modal-backdrop {
/* bug fix - no overlay */
display: none;
}
The problem persists if any ancestor of the [.modal] element has CSS property z-index set.
The [.modal] element inherits the CSS z-index from that container element.
While the [.modal-backdrop] is inserted into the [body] element dynamically from jQuery code, which has default z-index: 1040 from bootstrap.css.
I came out with two way CSS solution, is better than changing any other behavior of the default event and element.
Set the z-index: 1041 or higher value for the parent element of the [.modal], that ancestor element is causing the [.modal] is underneath the [.modal-backdrop].
Or
Set the z-index: 1039 or lower value for the [.modal-backdrop] in CSS file, if available. Because the HTML [.modal-backdrop] is not available in your code.
[Note: the CSS z-index property may require using !important flag]
[Note: default z-index: 1040 for [.modal-backdrop] is completely depended on bootstrap.css]
just remove z-index: 1040;
from this file bootstrap.css class .modal-backdrop
I was missing the follow html
<div class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
added it and worked without problems
Since I don't have the chance to move the modal markup since i added it in a partial template within a conditional what worked for me is add CSS bellow
.modal.fade {
display: none;
}
Then, when boostrap add class "in" through js apply display: block and everything works fine.
I Found that applying ionic framework (ionic.min.cs) after bootstrap coursing this issue for me.
If you can't put the modal to the root (if your use angular and the modal is in a controller for example), modifying bootstrap or using js is obviously a bad solution.
so saying you have your website structure:
//not working
<div>
<div>
<div>
<modal></modal>
</div>
</div>
</div>
open your code inspector and move the modal to the root, it should be working (but no where you want):
//should be working
<div>
<div>
<div>
</div>
</div>
</div>
<modal></modal>
now put it in the first div and check if it's working: if yes check the next child until it's not working and find the div that is the problem;
//should be working
<div>
<div>
<div>
</div>
</div>
<modal></modal>
</div>
Once you know which div is the problem you can play with the css display and position to make it work.
everyone has a different structure but in my case setting a parent to display: table; was the solution
Put this code wherever you want
$('.modal').on('shown.bs.modal', function () {
var max_index = null;
$('.modal.fade.in').not($(this)).each(function (index , value){
if(max_index< parseInt( $(this).css("z-index")))
max_index = parseInt( $(this).css("z-index"));
});
if (max_index != null) $(this).css("z-index", max_index + 1);
});
Many times , you cannot move the modal outside as this affects your design structure.
The reason the backdrop comes above your modal is id the parent has any position set.
A very simple way to solve the problem other then moving your modal outside is move the backdrop inside structure were you have your modal. In your case, it could be
$(".modal-backdrop").appendTo("main");
Note that this solution is applicable if you have a definite strucure for your application and you cant just move the modal outside as it will go against the design structure
just move your modal outside of all div contents, place it mostly prior to closing of body.
First make sure the modal is not in any parent div.
Then add
$('#myModal').appendTo("body")
It worked fine for me.
In Addition to all answers here, i found out, that the bootstrap4 "animated fadeIn" is also causing this error (not clickable modal behind background):
check if your modal is in the following parent tag (bootstrap animation)
<div class="animated fadeIn"></div>
I removed this tag - solved the problem for me.
this works for me.
<div class="modal fade" id="modalDecision" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="false">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-body text-center">
<asp:Label runat="server" Height="30px">Please select recovery delivery option</asp:Label>
<asp:LinkButton ID="btnEmail" CssClass="submit btn btn-primary" Width="100px" runat="server"
OnClick="ModalRecovery">Email</asp:LinkButton>
<asp:LinkButton ID="btnText" CssClass="submit btn btn-primary" Width="100px" runat="server"
OnClick="ModalRecovery">Text</asp:LinkButton>
</div>
</div>
</div>
var element = $('#modalDecision');
// also taken from bootstrap 3 docs
$(element).on('shown.bs.modal', function (e) {
// keep in mind this only works as long as Bootstrap only supports 1 modal at a time, which is the case in Bootstrap 3 so far...
var backDrop = $("<div class='modal-backdrop' style='z-index:-1;opacity:.5'></div>");
$(element).append($(backDrop));
});
i encountred this problem, and after investigating my css, the main container (direct child of the body) had:
position: relative
z-index: 1
the backdrop worked well after i removed those two properties. You may also encounter this problem if the main wraper have a position: fixed
I had a similar problem that the fade was not working and the overlay stayed on the page.
I had dynamic content added back to the page (refresh on some content only on modal action).
I also had this $('#rejectModal-'+itemId).modal('hide') (itemId is dynamic id for multiple modals in a single page for rejecting some information) but the problem was still not gone.
The overlay was staying because my layout was not set to null in the partial view
After setting this the problem was gone:
#{
Layout = null;
}
if you have nested modals this is the clue :
$('body').on('shown.bs.modal', '.modal', function (e) {
e.stopPropagation();
$(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
});

CSS absolute position alignment

I have a login form on my website that displays when a user clicks a button. It is a div that floats over other content. It only takes up a small portion of the page (directly below the sign in link).
It all works fine apart from one small thing. It displays aligned to the left of the sign in link (i attempted a diagram below).
|sign in|
|sign in stuff here|
I actually want it to look like this (align to the right of the sign in link):
|sign
in|
|sign in stuff here|
This is my HTML:
<div class="clear">
<a class="button" id="SignInBtn" href="#" onclick="toggleSignInBox(); return false;"><span id="spanSignIn">Sign In / Register <img src="../../Content/shared/arrow_down.png" border="0" /></span></a>
</div>
<div id="signinbox" style="display:none;">
<p>Who would you like to sign in with?</p>
<p>Google</p>
<p>Yahoo</p>
<p>Other</p>
</div>
And the CSS for the sign in box:
signinbox {background-color:#C1DEEE;
padding:10px; z-index:1; position:
absolute; top:66px; }
Is it possible to do this in just CSS?
Thanks
Wrap the signin info inside another div and call it inner-signin then position that relative to the absolute positioned outter div. You may also have to set the width on the absolute positioned outter div.
div.inner-signinbox {
position: relative;
right: 20px;
}
signinbox {
width: 250px; //ADD A WIDTH
background-color:#C1DEEE;
padding:10px;
z-index:1;
position: absolute;
top:66px;
}
If that does not work, why not just add a "left" property to the signingbox to set the horizontal position as well as the vertical. Is there a reason you don't can't absolute position the element with x and y?
I think you may want to try
float: right
or
text-align: right
Put the sign-in stuff inside the div containing the sign-in button.
Make the container position: relative.
Then give the sign-in stuff position: absolute; and right: 0;.
Incidentally, take care here; requiring Javascript merely to log in is pretty rude. A lot of people run NoScript for a variety of reasons.
I have created new div with class "main-pane". You can adjust the position of "signinbox". from the css by changing the value of "right" and "top".
<div class="main-pane">
<div class="clear">
<a class="button" id="SignInBtn" href="#" onclick="toggleSignInBox(); return false;">
<span id="spanSignIn">Sign In / Register <img src="../../Content/shared/arrow_down.png" border="0" /></span>
</a>
</div>
<div id="signinbox" style="display:none;">
<p>Who would you like to sign in with?</p>
<p>Google</p>
<p>Yahoo</p>
<p>Other</p>
</div>
</div>
.main-pane{
position:relative;
}
#signinbox{
width: 250px;
background-color:#C1DEEE;
padding:10px;
z-index:5;
position: absolute;
top:66px;
right:0px;
}
Thanks,
Arun Krishnan
