I am trying to have my background cover the page to create the parallax effect. Its the only thing missing as of now. Each "slide" div should cover the page. Here is the jsfiddle displaying the problem.
For my slides i am using the css styles:
.slide { background-attachment:fixed; width:100%; height:100%;
position: relative; padding:30px;}
and the html
<div class='slide' id='slide1' data-slide='1' data-stellar-background-ratio='0.5'>
<div class='container'>
<div class='row'>
<div class='col-md-6 slide-1-logo'>
<img src="img/MCP-LOGO-64x55.png" class='mainimg'>
</div>
<div class='col-md-6'><h1> Welcome!</h1></div>
</div>
</div>
<a class='button' data-slide='2' title=''></a>
</div>
You're .main class should have
height: 100%.
for the content to stretch fully.

I have two columns in a row with bootstrap 4. I want to use the whole screen to show the image. This is my code:
<div class="container-fluid" style="padding-left:0px;">
<div class="row">
<div class="col-md-6 ">
<img class="img-fluid" src="jumbo_background.jpg" />
</div>
<div class="col-md-6">
<div class="contact-wrapper">
<p>Test</p>
</div>
</div>
</div>
</div>
Everything is working good and responsive but this is the result I get from this code:
The preferred result I want is this:
The picture I use the dimension are 6000 X 4000
The solutions I have tried:
html, body {
height: 100%;
}
I have inspected the browser with the Google dev tool and I can see the the body is 100% but still not the result I want.
I have used h-100 from bootstrap and still get the same result.
I have used height: 100vh; but on smaller devices it's not responsive
I have checked this link:
Height not 100% on Container Fluid even though html and body are
Still don't get the result I want.
How can I give the image a full height in bootstrap 4?
UPDATE:
After nikolay solution on resolution: 1156 x 1013
You seem to want to use the image as a background. So my suggestion would be to do just that, as the cross-browser support is better (I'm not saying it can't be done with <img> alone, only that it's easier with background-image). Do note I'm leaving the <img> tag in for two reasons:
SEO indexing (if you need it)
sizing the column properly on mobile devices.
However, the <img> is not rendered. You're always looking at the background image of the <div>.
Here's a solution which grabs the src attribute of the first <img> element in each .column-image and uses it as <div>s backgroundImage. For it to work, make sure the <div> has the image-column class:
$(function() {
$('.image-column').each(function() {
const src = $('img', this).eq(0).attr('src');
if (src) {
$(this).css({ backgroundImage: `url(${src})` })
}
})
});
.image-column {
min-height: 100vh;
background: transparent no-repeat center /cover;
}
.image-column .img-responsive {
visibility: hidden;
}
#media(max-width: 767px) {
.image-column {
min-height: 0;
}
.image-column .img-responsive {
width: 100%;
height: auto;
}
}

<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js#1.16.0/dist/umd/popper.min.js"></script>

<div class="container-fluid">
<div class="row">
<div class="col-md-6 image-column">
<img src="https://i.picsum.photos/id/237/600/400.jpg" class="img-responsive">
</div>
<div class="col-md-6">
<div class="contact-wrapper">
<p>Test</p>
</div>
</div>
</div>
</div>
Note: even though it's used as both src of the <img> and background-image of the <div>, the resource (image) is only loaded once.
Here's a solution:
html, body,
.container-fluid .row,
.container-fluid .row .col-md-6,
.container-fluid .row .col-md-6 img {
height: 100vh !important;
}
Add example for the responsive mobile view as you made above, so I can write a solution.
I'm teaching myself how to create a parallax hover image using 5 layers, which is working perfectly, and I am able to resize the layers alright, but I'm having trouble with the positioning.
When resized to 150vw/vh the layers spill over the bottom and right side. I've tried a few things but not sure if I'm putting the css properties in the right place. 100vh/vw positions in the center but is too small for my header.
Should I be positioning in #scene or .img? And whats best practice for this kind of thing?
Heres what I have so far anyway:
<div class="section--parallax">
<div id="scene">
<div data-depth="0.2">
<img src="resources/img/layer1.png">
</div>
<div data-depth="0.6">
<img src="resources/img/layer2.png">
</div>
<div data-depth="0.3">
<img src="resources/img/layer3.png">
</div>
<div data-depth="0.6">
<img src="resources/img/layer4.png">
</div>
<div data-depth="0.2">
<img src="resources/img/layer5.png">
</div>
</div>
</div>
CSS
header {
background-size: cover;
background-position: center;
height: 100vh;
background-attachment: fixed;
}
#scene {
}
.section--parallax img {
width: 150vw;
height: 150vh;
}
JS
var scene = document.getElementById('scene');
var parallaxInstance = new Parallax(scene);
I have had some problems to resolve this situation.
I have a div "header" with no set height because could have a variable value depending on browser.
Inside her I have two more divs and I want to place one div exacly at the bottom of the another but I never know height "header" height. I tried to define a height for div "header" but sometimes it fails.
Use position:absolute in combination with a positioning context on the parent, for example:
<header>
Ohai
<div>
Noes!
</div>
</header>
CSS:
header {
position:relative;
height:25%;
background:#eee;
}
div {
position:absolute;
bottom:0;
left:50%;
margin-left:-50px;
width:100px;
background:red;
}
The header's size is unknown, since it's based on the viewport height, and the div is locked to its bottom with the combination of position:absolute and bottom:0. The header needs the position:relative to designate it a positioning context used by absolutely positioned child elements.
Fiddle here.
One way to do this would be to set position:relative on the header div, and position:absolute and bottom:0 on the child div you want to sit on the bottom of the header.
jsFiddle example
just use clear:both for the second div at bottom ,and set the height of the header as height:auto
Sample:
<div id="header">
<div id="first">
first
</div>
<div id="second">
second
</div>
</div>
CSS:
#header{height:auto}
#first{}
#second{clear:both}
DEMO
<div id="header">
<h2>Some title..</h2>
<div class="right">
<p style="color: black;display: inline">
Some data.....
</p>
</div>
<div class="left">
<form action="#" >
<input type="text" placeholder="put here..." required="required">
<button type="submit">Validar</button>
</form>
</div>
</div>
CSS:
#header{position: relative;height: 150px; border:1px solid black}
.right{right: 0; bottom: 0; top:auto; position: absolute}
.left {left: 0; bottom: 0; top:auto; position: absolute}
This work just fine in Chrome and Firefox but is not working in IE.
The div which have the left css is not being placed at the bottom of the "header".
<div>
<div>
div1
</div>
<div>
div2
</div>
</div>
A div in which I would be sliding in images , I want the images to appear in only a certain area of the div, say a triangle shaped area. The rest of the div should just show whatever is underneath the div.
CSS:
#overlay {
width: 700px ;
height: 300px ;
position: absolute;
top: 50px;
left: 50px;
z-index: 100;
background: url("img/overlay.png");
background-repeat: no-repeat;
}
HTML:
<div class="boxcat" id="websitesbox">
<div id="overlay"></div>
<div id="websitesSlider">
<img src="img/seanswers.PNG" alt="Seanswers screenshot">
<img src="img/stories.png" alt="Seanswers screenshot">
<img src="img/PerfectUpload_1.png" alt="Seanswers screenshot">
</div>
</div>
Here I would be sliding in the images into overlay, BUT I don't want the images to show up completely , instead just a part of the overlay div should be covered in the image.
Not sure If I am making any sense. If I am is this possible ?
Thanks
You want to use mask-image however it isn't widely supported by the browsers.
Here you can read about the spec: http://www.w3.org/TR/css-masking/
And here you can see the support: http://caniuse.com/#search=mask
you can next websitesSlider into overlay:
<div class="boxcat" id="websitesbox">
<div id="overlay">
<div id="websitesSlider">
<img src="img/seanswers.PNG" alt="Seanswers screenshot">
<img src="img/stories.png" alt="Seanswers screenshot">
<img src="img/PerfectUpload_1.png" alt="Seanswers screenshot">
</div>
</div>

I have a large image, and a bunch of divs that I'm using as fake buttons on top of said image. Currently, I'm using absolute positioning to place the divs where I want them to be, but I've got a lot of divs, and finding the x/y coords by trial and error is time I don't want to take. Is there an easier way to position them, or am I stuck?
I'm using jQuery and Javascript in this project, so these can be used for solutions.
CSS:
#test0 {
position:absolute;
left:381px;
bottom:100px;
}
HTML:
<div id="image">
<div id="test0" class="button" onclick="$('#modal').dialog('open');" style="postion:absolute">
Click me to test Modal!
</div>
<div id="test1" class="button" onclick="$('#modal').dialog('open');" style="postion:absolute">
Click me to test the same Modal!
</div>
<img src="testImage.jpg" alt="testtest" />
</div>
HTML:
<div id="image">
<div id="container-of-fake-divs">
<div class="fake-div">FAKE DIV</div>
<div class="fake-div">FAKE DIV</div>
</div>
<img src="image.jpg" />
</div>
STYLE:
#image { position:relative; }
#container-of-fake-divs { position:absolute; top:0; left:0; }
.fake-div { display:block; }
