I have the following HTML structure:
<section class="mysection">
<div class="parallax">
<div>
<svg></svg>
</div>
</div>
</section>
<section class="back">
<div class="triangle">
<img src="img/red-triangle-bkgrd.png">
</div>
</section>
This is the CSS in LESS:
.parallax{
width: 90%;
margin-left: auto;
margin-right: auto;
}
section.back {
.triangle {
position: relative;
img {
position: absolute;
right:0;
top: 0;
}
}
}
Before using parallax on the parallax, back just sits immediately below the bottom border of mysection.
When I scale parallax by 1.11111111, the parallax uses 100% width of the viewport. However, back does not sits right beneath the parallax anymore. Instead, it overlaps with the parallax area. Here is a picture of a real-life situation:
How can I make back in the overlap area invisible? Put it another way, how can I make svg or its containers completely opaque without showing the overlaped image beneath it?
I tried 'opacity:1` on svg and its containers, but it is not working.
To be more detailed, I use a tool called ScrollMagic for this work if this is relevant.
You can set the stacking order using z-index. Try setting the following:
.mysection {
position: relative;
z-index: 1;
}
This should ensure that whatever's in your .mysection (such as the svg/map) passes over whatever intersects (assuming you don't apply a greater z-index to the other elements).

I want to have an object falling from the sky while scrolling down the page. The idea is: You have the object div not moving. It should be in the center of the page (50 px from the top of its parent) and when you scroll down it should scroll down too.
Whats the catch? The object is in another div. I only want the object to be visible inside this div. So not on the entire website.
What have I tried?
1: Fixed positioning, but then it shows up on the entire page, z-index does not work with fixed.
2: Relative positioning on the parent and absolute on the child but then the object div does not go down the page when I scroll.
Visual representation::
On scroll down:
React Component:
<div className="container">
<div className="container--object">
<img src={object}/>
</div>
</div>
CSS
.container {
min-height: 100vh;
position: relative;
}
.container--object {
position: absolute;
top: 50px;
}
My parent component is the homepage. And the siblings of this react component are other div's. The functionality to make the div move down the page is what I am struggling with, how can I move the object div down? Is there a way to base it off the top of the browser?
Ok if i understood correctly, you want something like this? I used an image and some test text
.container {
min-height: 100vh;
height: 2500px;
position: relative;
}
.container_object {
position: fixed;
top: 50px;
}
<div class="container">
<div class="container_object">
<img src="https://images.pexels.com/photos/414612/pexels-photo-414612.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500" />
</div>
<div style="position: absolute; top:500px">
TEEEEEEEEEEEEST 111111111
</div>
<div style="position: absolute; top:800px">
TEEEEEEEEEEEEST 222222222
</div>
</div>

Say I have three divs like following:
<div class="wrapper">
<div class="container">
container1
<div class="element">
fixed
</div>
</div>
<div class="container2">
container2
</div>
</div>
I want div: element to be fixed when it is inside div: container, but its position should become absolute when div: container2 becomes visible, it should not overlap with div - container2, but scroll away at that time with div: container.
A pure CSS solution is preferable, but if not possible I may go for a JS or jquery solution. I have created a fiddle for this, and tried some solution suggested here, which are not working.
What I would suggest is to use javascript to recognize when the scrolling is at a certain point with window.pageYOffset
When it reaches your desired window Y Offset you can start an event that modifies the css value of the positioning from fixed to absolute (by setting the parent container to relative) and bottom at 0.
Check out this jsfiddle https://jsfiddle.net/zq0kkkcx/2/
Also, this is the code that I'm talking about:
document.addEventListener("scroll", function(event) {
if(window.pageYOffset >= 1200){
console.log("1200");
// this is where you want your element to become absolute
// positioned to his parent container
// write your css changes here and apply them to elements
// add relative to container and absolute with bottom 0 to element
} if (window.pageYOffset <= 1200){
console.log("<1200");
}
});
If you want a CSS solution, here is a trick that you can do using z-index. Other than this there is a JS solution.
.wrapper {
width:100%
}
.container {
width:300px;
margin:0 auto;
height:1200px;
background:#ccc;
position: relative;
z-index: -1;
}
.container2{
width:300px;
margin:0 auto;
height:1200px;
background:#fcf;
z-index: 1;
}
.element {
background:#f2f2f2;
position:fixed;
width:50px;
height:70px;
margin-left:250px;
border:0px solid #d6d6d6;
}
<div class="wrapper">
<div class="container">
container1
<div class="element">
fixed
</div>
</div>
<div class="container2">
container2
</div>
</div>
You're looking for a sticky header. There is currently no way to make a header sticky at an arbitrary scroll position using pure CSS - you'll have to look into a JavaScript solution to accomplish that.
Yes, it is 100% possible to do this without any JavaScript
I updated your fiddle
Markup should be like this
<div class="wrapper">
<div class="outer-scroller">
<div class="scroll-container">
container1
<div class="fixed-header">
fixed
</div>
</div>
</div>
<div class="last-container">
container2
</div>
</div>
and css
.wrapper {
width: 100%;
height: 300px;
}
.outer-scroller {
height: 140px;
overflow-y: scroll;
}
.scroll-container {
padding-top: 70px;
width: 300px;
height: 1200px;
background: #CCC;
}
.last-container {
width: 300px;
height: 600px;
background: #FCF;
}
.fixed-header {
background: #F2F2F2;
position: absolute;
width: 300px;
height: 70px;
top: 0;
pointer-events: none;
}
You'll see I've added an outer-scroller div.
The next bit is changing your CSS slightly
The new outer-scroller div is double the height of your fixed-header (for the purposes of this example) and it has an overflow-y: scroll on it.
The container inside there is still the same.
The next change is turning your position: fixed into a position: absolute and then adding padding to the top part of the div you want to scroll in order to push its content "below" the new "fixed" header.
Scrolling over the outer-scroller div then makes its content scroll, and because its height is set with an absolute element on top it then scrolls "under" the fixed header.
Once the bottom of its child content scroll-container is reached, the whole page then continues scrolling, and you get the illusion of the header disappearing.
The last bit is pointer-events: none on the header so that it doesn't scroll away when the cursor is over it (but the div below does)
The template I am working with has a container, with content and navigation divs. The code looks something like this:
<div id="user_content" class="user_content">
<div class="main_content"> some content, text and whatever else, can be pretty long!</div>
<div class="content_nav">
<div class="col-md-3"><a id="prevB" href="http://google.com">CLICK HERE TO GO BACK!</a></div>
<div class="col-md-3"><a id="nextB" href="http://yahoo.com">CLICK HERE TO GO NEXT!</a></div>
</div>
</div>
See Figure 1 below for drawing.
Relevant CSS for the main_content div:
.main_content {
position: relative;
left: 0px;
width: 100%;
display: block;
transition: transform 0.5s ease 0s;
height: auto;
}
I can change the PHP to generate the BACK and NEXT links without its own div, so it will look like this:
<div id="user_content" class="user_content">
<a id="prevB" href="http://google.com">CLICK HERE TO GO BACK!</a>
<div class="main_content"> some content, text and whatever else, can be pretty long!</div>
<a id="nextB" href="http://yahoo.com">CLICK HERE TO GO NEXT!</a>
</div>
</div>
What I don't understand is the proper CSS to make the <a> BACK and NEXT links to be on the left and right side of the main_content container. See Figure 2 below for drawing.
Here is a link to the JFIDDLE that I've tried: https://jsfiddle.net/7wet25zn/
Position absolute your anchors at top 50% and subtract 0.5em (half the font-size, or any other value):
.user_content {
position: relative;
background: #eee;
height: 160px;
}
.user_content a {
position: absolute;
top: calc(50% - 0.5em);
}
.user_content a.next {
right: 0;
}
<div class="user_content">
<div class="main_content"></div>
<a class="prev" href="#!">PREV</a>
<a class="next" href="#!">NEXT</a>
</div>
If your {content} part is tall and prev and next button should be in the middle of the viewport (not tall div), you may add display:block; position:fixed; top:50%; to prev and next links so it will be visible regardless of height of div.
I recently experienced a similar problem building tooltips on a page. It wasn't something I had encountered before and wanted to do it with HTML and CSS. What ended up working for me was defining a parent container and making the content you want floating like so:
<div class="parent-container">
<div class="child"></div>
<div class="child"></div>
</div>
And defining the CSS as such:
.parent-container {
position: relative;
}
.child {
position: absolute;
}
This allows you to set width and height on the child class as relative to the position of the parent container. Good luck!
To start off I'm relatively new to CSS, Bootstrap and HTML. I want to position a responsive element at the bottom of the screen.
So I have this code which makes it behave responsively:
<div class="col-sm-12">
test
</div>
But how do I get it to stick to the bottom of the page? I already tried ID/ Class selectors with an absolute position. It moved the element to the bottom, but it wasn't responsive anymore.
One solution might be to wrap the desired element in another div, then target the wrapper element to fix it to the bottom of your screen. Your markup could look like:
<div class="fixed-container">
<div class="col-sm-12"><!--your content here--></div>
</div><!--end .fixed-container-->
And you styles could look like:
.fixed-container {
position: fixed;
bottom: 0;
left: 0;
width: 100%;
}
This would affix the .fixed-container element to the bottom left of the viewport, and would set the width to 100% of the viewport. The layout-specific rules applied to .col-sm-12 would remain intact.
<div id="my-element" class="col-sm-12">
test
</div>
#my-element {
position: fixed;
bottom: 0;
}
Here is a simple solution to your problem.
Make sure your elements are in a wrapping div. Since you are using Bootstrap, use:
<div class="container-fluid">
Inside this container place your elements/sections including your footer:
<footer class="col-md-12">
Your footer should have the following CSS.
footer {
position: absolute;
bottom: 0;
height: 100px /* Height of your footer */
width: 100%;
}
Here is a fiddle. You can see the footer is at the bottom of the container which has a black border.

I've been tasked with changing a website around a bit, and right now, the website has a responsive layout that is 95% of the viewports width, body-wise, so it will adjust if resized.
This is great, I want it to keep doing that, but I want the footer to have a side-to-side calm blue background, and I'm not able to come up with a way to do that for some reason.
Can anyone help?
Try this - DEMO
HTML
<div id="container">
<h1>TITLE</h1>
<section>MAIN CONTENT</section>
<footer> FOOTER </footer>
</div>
CSS
#container {
width: 95%;
margin: auto;
background: honeydew;
}
footer {
position: absolute;
width: 100%;
background: beige;
margin-left: -2.5%;
}
body contains all the other elements. You thus aren't supposed to have one larger than body inside of it.
Although you could position it absolutely to the bottom-left corner (position: absolute; bottom: 0px; left: 0px;) with a width of 100% and possibly make it work, I'd suggest you instead make a container element, perhaps a div, inside of the body element that contains your 95%-width elements and place the footer outside of that container.
I am not sure of which method is more reliable, however.
Have You tried to wrap existing 'header'component by other 'wrapper' component (div, span, etc.)? Example:
<div id="wrapper" width="100%"
<div id="header" width="95%">
some header stuff here
</div>
<!-- foo bar -->
<div id="footer" width="100%">
my footer
</div>
</div>
