I'm using Ant Design for my website frontend, a similar framework like Bootstrap for React JS, but not really relevant here, since this is a pure CSS question.
The framework uses rows and columns that are relative. Now I want to overlay the parent element with an absolute element that is nested deep inside in it. I don't want to change the CSS of the rows or columns and I don't want to move the absolute container outside of my nested elements.
Is this possible, if so, how?
.row { /* copied from Antd */
position: relative;
height: auto;
margin-right: 0;
margin-left: 0;
zoom: 1;
display: block;
}
.col { /* copied from Antd */
flex: 0 0 auto;
float: left;
position: relative;
min-height: 1px;
padding-right: 0;
padding-left: 0;
}
.test {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-color: #333;
}

<div class="row">
<div class="col">
<div class="test"></div>
</div>
</div>
</div>
</div>
</body>
</html>
The desired effect looks like this, but I'm unsure if this is really possible:
The test container should start where its parent column starts, but be greedy. Is this even possible? I have no problems to add more divs around the test container, though.
Make the absolute element big enough and hide the overflow where you want:
.row {
/* copied from Antd */
position: relative;
}
.col {
/* copied from Antd */
position: relative;
}
.test {
position: absolute;
top: -100vh;
right: -100vw;
bottom: -100vh;
left: -100vw;
background: rgba(0, 0, 0, 0.8);
z-index: 2;
}
<div>This line should stay visible.</div>
<div class="row">
<div class="col">
<div>Right below this line it should be darken:
<div class="row" style="overflow:hidden"> <!-- hide here -->
dark content here
<div class="col">
dark content here
<div class="test"></div>

How to overlay images
(11 answers)
Closed 3 years ago.
I am trying to to center text over multiple images using bootstrap and css. Most googling says i need to use position: absolute;
However the most i am able to do is center the text in the middle of the screen but not over the image. I believe its something with bootstrap but i cannot find what is blocking it
The goal is for the text to have animation over the image moving forward like fading in and such
I have already checked multiple post about this but they all seem to only work if its one image. Trying to do with with multiple images seems to require a different approach
EDIT:
Since this got marked as a duplicate i would like to point out that the other post only show this working with ONE image. The other post do not work when it comes to multiple images
The portion of the code in question:
.imgText {
position: absolute;
z-index: -1;
}
.imgList {
z-index: -2;
}
<div class="row justify-content-center mt-3">
<div class="ml-4 imgList">
<img src="https://via.placeholder.com/200x200">
<div class="imgText justify-content-center m-auto">
test text
</div>
</div>
<div class="ml-4 imgList">
<img src="https://via.placeholder.com/200x200">
<div class="imgText justify-content-center m-auto">
test text
</div>
</div>
</div>

You need to set the parent element to be position: relative, so it's relative to the absolute positioned element, in this case the text.
This centers the element horizontally and vertically:
top: 50%;
left: 50%;
transform: translate(-50%, -50%)
Also you need to apply z-index in order for the text to appear above the image.
.ml-4 {
position: relative;
}
.imgText.m-auto {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
z-index: 10;
}

I've been working on a personal website and am trying to get a particular scrolling effect, where the page is separated into sections and each section overlaps the next section. Meanwhile, the content of each section stays fixed so that the content for each section never moves, but rather is revealed by each section scrolling into place.
My issue is that with the code I have now, I have achieved this effect in Safari, but when I open the same file in Chrome, it doesn't work at all. I isolated the particular effect I am going for in the following code:
* {
box-sizing: border-box;
padding: 0;
margin: 0;
}
.section {
height: 100vh;
overflow: hidden;
position: -webkit-sticky;
/* position: -moz-sticky;*/
/* position: -ms-sticky;*/
/* position: -o-sticky;*/
top: 0;
}
.fixed {
position: fixed;
top: 50%;
left: 50%;
}
#first {
background-color: lightgrey;
z-index: 1;
}
#second {
background-color: lightblue;
z-index: 2;
}
#third {
background-color: black;
color: white;
z-index: 3;
}

<div class="section" id="third">

</html>
If you open this code in Safari, you will see the effect, but if you open it in Chrome, it is completely different.
I am assuming the problem lies in my CSS file, but from the research I have done, I cannot find any disparity in the way Chrome treats any of the individual CSS properties I used compared to how Safari treats them. Is there something I am missing?
I'm using wordpress with a custom template and I want to display a div the width of the window. This is my html code:
<section id="calltoaction" class="calltoaction " style="background-position: 50% 15px;">
<div class="blacklayer"></div>
<div class="container">
<div class="row">
<div class="col-md-12">
<h2>Title Text</h2>
<p>Test Text</p>
</div>
<div class="col-md-12 text-center">
Download
</div>
</div>
</div>
</section>
This is my css code:
.calltoaction {
background-position: unset !important;
position: absolute;
left: 0;
right: 0;
background-image: url(http://roguelevels.com/wp-content/uploads/2018/04/DSC6507-683x1024.jpg);
background-size: cover;
padding: 80px 0 90px 0;
}
The problem is, everything I create gets placed within this div class:
.row {
margin-right: -15px;
margin-left: -15px;
}
So i'm trying to write custom css to create a div that displays over the top of this class as I don't have access to the template's code directly.
At the moment the result is this. I want that image to fit the width of the page.
Any help would be greatly appreciated.
See attached code-snippet for how to stack divs ontop of each other, assuming one div has setting: position: absolute; . I moved the lowest div slightly so it is visible.
.div-1 {
position: absolute;
z-index: 1;
background-color: red;
height: 100px;
width: 100px;
margin: 10px 0px 0px 10px;
}
.div-2 {
position: relative;
z-index: 2;
background-color: green;
height: 100px;
width: 100px;
}

I have a parent DIV with a child DIV that I'd like to have stretch to the bottom of the parent. At present it does not despite having height:auto!important; A screenshot illustrating the issue can be seen here.
The relevant HTML (as a Jade template) is as follows:
.main.top0
.infoPanel.koneksa_bg_blue
.innerPanel.mtop0.mbottom0
.infoCaption.font8em.koneksa_white 404
.infoCaption.koneksa_white We can't find the page you are looking for
.infoCaption.koneksa_white
| Don't worry. Just try to go back or
a.koneksa_white.underline(href='/') home
.footer.stickyBottom.koneksa_bg_gray.koneksa_fg_light_gray
The main DIV is the parent and the infoPanel is the child (colored in blue in the image above) that I am struggling to stretch.
The corresponding CSS is as follows:
.main {
width:100%;
min-height:700px;
height:auto!important;
overflow: hidden;
z-index: 1;
top:3em;
position: relative;
}
.infoPanel {
width:100%;
height:auto!important;
display: block;
padding:0;
}
.innerPanel {
width:90%;
padding:40px 0;
height:auto!important;
margin:0 5%;
display: block;
}
I'm aware that this is a fairly common question but it seems like the answer is always to include a hard-coded height. I would like to avoid this because while that was a perfectly fine solution for the desktop styling this is intended to be displayed on mobile devices and as such I'd like it to be a bit more responsive than a hard-coded height.
Thanks for any insights that you can provide.

One solution that works in all modern browsers is to do the following:
html, body {
height: 100%
}
.main {
position: absolute;
top: 3em;
bottom: 0;
width: 100%;
}
This seems an unusual solution but modern browsers will actually respect all 4 sides being defined at the same time and stretch the element to match. Here is an example jsFiddle: http://jsfiddle.net/nqt7vqs1/2/
You can do the same with all child elements as well because position: absolute implies position: relative for the purposes of positioning child elements.
If this solution doesn't work, another option is to do the following:
html, body {
height: 100%
}
.main {
position: absolute;
top: 0;
height: 100%;
margin: 3em 0 -3em 0;
overflow: hidden;
}
This is a "hidden margin" trick that also works in all modern browsers. Same Fiddle with these settings: http://jsfiddle.net/nqt7vqs1/3/
Is there a way to make a div appear half off-screen using just CSS without knowing the width of the div?
Unless I've misunderstood the question, I think it is possible with CSS, as I hope should be clear from this jsfiddle.
Example HTML
<div class="container one">
<div class="half">Hello there.</div>
</div>
<div class="container two">
<div class="half">Hello there, you old dog.</div>
</div>
<div class="container three">
<div class="half">Hello there you old dog. Been up to your old tricks?</div>
</div>
The CSS
.container {
position: absolute;
}
.half {
position: relative;
right: 50%;
}
.two {
top: 30px;
}
.three {
top: 60px;
}
Actually, no.
The div will have it's top positioned at 50% the screen... you could assume values that would "sort of" make it look like it would be in the middle if you knew more or less the height of the div before-hand. But in short, no.
Only with tables or Javascript.
i made something from jQuery. Hope its what you are after - http://jsfiddle.net/6Guc8/1/. it gets half the width of the element and then chucks half of it out the screen.
here is the jquery
$(document).ready(function(){
var half_width = $("div").width() / 2;
$("div").css("left", -half_width);
});
here is the css
div{
background: #555;
height: 100px;
width: 100px;
position: absolute;
}
here is the html
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.7.1.min.js" type="text/javascript"> </script>
</head>
<body>
<div>
</div>
</body>
</html>
It is absolutely possible in CSS only. You need 1 wrapper div, however:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
div#wrapper {
position: absolute;
left: 0;
}
div#wrapper div {
position: relative;
padding: 30px;
background: yellow;
left: -50%;
}
</style>
</head>
<body>
<div id="wrapper">
<div>this div is halfway hidden, no matter what size it is.</div>
</div>
</body>
</html>
