I have the below Ionic application example in Stackblitz. You'll see that there are a custom Angular component called <my-video></my-video>, an ion-list and a button. What I want is:
Put the ion-list on top of the video. This way, the ion-list overlaps the video.
Put the button under the video.
This is what I have now, you can see the code in the Stackblitz example (including the CSS code):
I think the problem can be that video-container hasn't the same height as its children my-video, but I don't know why.
I tried with different positioning configurations (position relative, absolute , static, etc.) with no effect.What would be the correct way to achieve this?
I believe the problem is that my-video is absolutely positioned, meaning it is taken out of the natural flow of positioning and positioning the button anywhere based on my-video very tricky, which is not what we want, so you need to make my-video's positioning relative, keep the options-list position absolute but also add top: 0 and left: 0, like so
.video-container {
position: relative;
my-video {
position: relative;
width: 100%;
background-color: red;
}
.options-list {
position: absolute;
top: 0;
left: 0;
}
}
.finish-button-container {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
padding-bottom: 32px;
position: relative;
}
now the button can go to the bottom of the screen because my-video is in the flow of positioning
Updated the stackblitz with the following css for your button :
position: absolute;
top: 40%;
left: 50%;
right: 50%;
You need to use position: absolute here in order to get your button's position relative to the .video-container div.

I want to create a slider, so here is the code:
div#list_container {
position: relative;
width: 100%;
}
div#first_list {
position: absolute;
left: 0px;
top: 0px;
}
div#second_list {
position: absolute;
left: 70%;
top: 0px;
}
<div id="list_container">
<div id="first_list">
<h1>Smth</h1>
</div>
<div id="second_list" class="aim_list">
<h1>Smth</h1>
</div>
</div>
<h2>Following elements</h2>
It kinda works (I would just change left property to move them), but since parent (div#list_container) is positioned as relative, so it doesn't cover children elements, so another elements, which will go after slider are shown above it. How can I fix it?
When you change position of child elements to absolute, they are no longer relative to their parent element. Either make parent absolute while changing children's position to relative, or add height to parent.
I also highly recommend implementing this using CSS Flexbox, otherwise it will be very difficult to maintain. See if you can work with this:
#list_container {
position: absolute;
width: 100%;
display: flex;
justify-content: space-around;
}
#list_container > *{
flex-grow: 1;
}
The problem is that, since your child elements are with absolute positioning, there is nothing that actually expands the box of the parent element. To fix it, you can add height to the div#list_container, depending on your design target.
I'm placing a fixed position modal inside a relatively positioned element with no transforms and with overflow: auto.
The problem is that when there is overflow on the parent, the modal's backdrop does not cover the scrollbars - please look at the picture attached for an example.
The scrollbar should also be covered by the semi-transparent black backdrop, but for some reason it is not. Does anyone know why, and/or how I may go about fixing this?
I want to avoid using absolute positioning for the modal container because it can be a nested element in any arbitrary hierarchy.
Here is my css for the .modal-container class which includes the backdrop.
.modal-container {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0,0,0,.5);
opacity: 1;
transition: all .1s;
display: flex;
z-index: 200;
justify-content: center;
align-items: center;}
Actually this is a problem I encountered during the developing of blogger.
I want to write a navbar on my own, but the width of parent elements limit the style width:100%, even if I set the float properties to it.
Please see the image above. Only nav's HTML/JS/CSS are configurable. So how can I configure the CSS Style of class nav to archive this goal?
Or, If you have relevent experience in developing blogger, please tell me.
Thanks a lot!
use position absolute for your nav. Look at this FIDDLE
html :
<div class="first">0</div>
<div>
1
<div class="nav">NAV</div>
</div>
<div>2</div>
css :
div { background: grey; width: 75px; height: 50px; margin: 20px auto; }
.first { margin-top: 75px; }
.nav { background: red; position: absolute; top: 10px; left: 0px; width: 100%; margin: 0; }
EDIT
Your nav is in a position:relative; well you can append your nav to your body with that jquery (HERE THE FIDDLE UPDATED):
$(".nav").appendTo("body");
To achieve that kind of 'layering' you probably need to use absolute positioning, especially if your options are limited. This has the obvious caveat of taking it out of the page's flow, so you'll need to ensure your page is never too short for it to be visible. It won't affect other elements around it either.
So, something like:
nav {
left: 0;
position: absolute;
top: 400px;
width: 100%;
}
Hopefully one of its parents has a position: relative; so the nav knows where to use as an origin point when positioning absolutely, otherwise it'll use the top left of the browser pane.
You may also need a z-index value if you want your nav to appear behind the content.
Not sure if this is what you are searching for, but you can try giving your naviation position: absolute; and width: 100%;. This will get the navigation element out of the flow of the document.
How we can add a div tag over a slideshow like in the following link
http://www.hellofresh.com/
Here the div with title "DISCOVER THE JOY OF COOKING " is placed over a slideshow.
How might I do this?
First of all, welcome to Stackoverflow (oops; this isn't your first question!). The key to placing your div over the slideshow (or over any other element) is using absolute positioning. Absolute positioning enables you to specify the exact position for an element instead of leaving it with the flow of the document. If you take a look at your example website's CSS, you can see that the div that has "Discover the joy of cooking" is styled basically like this:
position: absolute;
top: 0px;
left: 0px;
top and left act somehow like x and y in a 2-dimensional grid system, except that the origin is placed differently. top: 0px; pulls the div up and left: 0px; pulls the div left, so all-in-all, it's placed on the upper-left corner.
To achieve the effect of the translucent black, you use the opacity property. opacity: 0.5; means that the div is half-opaque, while opacity: 0; means it's not visible at all. Your favorite value might be something like opacity: 0.7; -- anything in the range 0...1.
The last piece here is to tell the browser that the div should be over the slideshow, not behind it. To do that, use the z-index property. z-index specifies the relative "stack order" of elements. So if you want your div to be over the slideshow, style it with z-index: 5; while styling the slideshow with z-index: 1;, for instance.
Hope that helped at all!
Ok, you can do something like this ( http://jsfiddle.net/YgpqX/ ):
<div class="div1"></div>
<div class="div2"></div>
.div1 {
width: 320px;
height: 200px;
background: #aa5;
}
.div2 {
width: 100px;
height: 100px;
margin-top: -200px;
background: #5aa;
}
Or ( http://jsfiddle.net/YgpqX/1/ )
<div class="div1"></div>
<div class="div2"></div>
.div1 {
position: relative;
width: 320px;
height: 200px;
background: #aa5;
}
.div2 {
position: relative;
width: 100px;
height: 100px;
top: -200px;
background: #5aa;
}
And if your block in html should be earlier then slider block, then use z-index: 9999; to get it up.
And also abolute position:
<div class="div1">
<div class="div2"></div>
</div>
.div1 {
position: relative;
width: 320px;
height: 200px;
background: #aa5;
}
.div2 {
position: absolute;
width: 100px;
height: 100px;
background: #5aa;
}
By setting the opacity property in CSS
This is some basic info on this one W3schools Css opaque
They are accomplishing this effect using CSS Positioning. Basically they are absolutely positioning the discover the joy of cooking block over the slide show. You can use z-index on the absolute position div to bring it over the relative position (slideshow) div. Basically you need to use a combination of position and z-index. I have a basic example of the CSS/HTML here: http://jsfiddle.net/jqVAe/1/
HTML:
<div id="slideshow">
Scrolling sideshow goes here. Scrolling sideshow goes here. Scrolling sideshow goes here. Scrolling sideshow goes here. Scrolling sideshow goes here. Scrolling sideshow goes here.Scrolling sideshow goes here.
<div id="over-slideshow"></div>
</div>
CSS:
#slideshow{
width: 400px;
height: 200px;
position: relative;
background: green;
}
#over-slideshow{
position: absolute;
top: 10px;
left: 10px;
width: 100px;
height: 100px;
background: red;
}
This provides a basic structure in which to put your slideshow. I would recommend finding a good slide show plugin and not trying to reinvent that functionality. I'm sure there are plenty of Jquery (Javascript Framework) plugins that will accomplish this task for you.
You may try position: absolute and z-index. z index is used to align a layer over or under a layer. You may go through;
Lesson 15: Layer on layer with z-index (Layers), Understanding CSS z-index, and A Detailed Look at the z-index CSS Property
I've a div element <div class="getBack">Get back to portfolio!</div>
and some css
.getBack{
height: 70px;
width: 100%;
position: fixed;
z-index: 99;
}
And for some reason, this position fixed doesn't work and I don't know why.
It just scrolls up, out of sight
You might need to set an actual position like top: 0; right: 0;. Also, make sure the parent element you want .getBack to be fixed relative to has a position other than static.
