Let's say that I want to have layout that doesn't scroll (meaning width=100, height=100) with one container and
two child elements. Now, when you don't apply any of the positioning context, all the elements follow natural flow of the document which means they stack below each other. How do I achieve positioning along the z-axis (stack them in front of each other) without using absolute positioning?
To be precise, here is fiddle:
https://jsfiddle.net/Rokke/wb10ozme/7/
<div class="wrapper">
<div class="child-01">Child-01</div>
<div class="child-02">Child-02</div>
</div>
html {
width: 100%;
height: 100%;
overflow: hidden;
}
.wrapper {
width: 100%;
height: 100%;
background-color: black;
}
.child-01 {
width: 350px;
height: 450px;
background-color: red;
}
.child-02 {
width: 650px;
height: 350px;
background-color: blue;
}
What I want to achieve: child-01 centered horizontally on the page along the bottom edge of the screen, child-02 centered horizontally as well but in front of child-01. I accomplished this by using absolute positioning but then when you open up the developer tools it moves (because of the bottom: 0 property). If I was to use position relative I would have to use negative margin to bring them in front of each other. Does anyone have some idea how this can be achieved in a much better way?

I know how to make an element scrollable (inner element absolute and parent relative), but what if I want the whole scrollable element to be positioned as absolute? (to move it around a parent div and overlap something underneath). Am i correct to assume it's not possible? Is there a way to do it via javascript?
I already tried to wrap the relative parent into an absolutely positioned grandparent but obviously it doesn't work :/
Ok I actually solved it by moving the scrollable element into a component (I'm working in React), importing it into the main component, and then I set the position of the component to absolute. However, I'm still interested in knowing if other people have other solutions
Can you just add an overflow on the absolute positioned item?
Something like this?

I am currently building a website with weblflow but run into a problem that someone here might be able to help me with. The is an issue I have for multiple projects, so I would really appreciate someone's help.
Basically, if you have an image full screen size (set as background image, 100vw and 100vh), and then want to put headings/labels on top of that image pointing to specific sections in that image, how do I get these headings/labels always move with the image when someone would resize the browser?
As for now I used absolute positioning for the headings/labels and used % margins to position them where I want them to point to on the image. The image itself I have set to position relative. However, with that solution the headings/labels never exactly continue to point to the same spot on the image when resizing the browser.
I think the main issue is that when someone only changes the browser's width, the image gets (for example) smaller bc it keeps it's ratio. Vertically the headings/labels don't move bc the height was unchanged, it's just the browser's width that was changed. So horizontally it's still fine but vertically the headings are off now since the image got smaller due to resizing the browser's width. So I guess I do know why it's not working but I don't know how to fix this. If someone has a solution for this, please let me know.
As an example: if you open this page: http://nestin.bold-themes.com/classy/ and scroll down to the section ‘True value is always inside’, there is an image with 5 numbered labels, no matter how you resize the browser, these labels/numbers stay in the same spot of the image. I see this quite often on websites. How was this achieved?
Would appreciate any help!
You create a parent wrapper, put inside the image and all the divs.
the parent is relateive and the divs are absolute.
here's a small demo.
* {
box-sizing: border-box;
margin: 0;
}
img {
max-width: 100%;
display: block;
width: 100%;
}
.parent {
position: relative;
}
.parent .box {
position: absolute;
width: calc(1.6vw + 10px); height: calc(1.6vw + 10px);
border-radius: 50%;
background-color: #fff;
display: -webkit-box;
display: flex;
-webkit-box-pack: center;
justify-content: center;
-webkit-box-align: center;
align-items: center;
}
.parent .box.window {
top: 0;
left: 39%;
}
.parent .box.light {
top: 16%;
left: 46%;
}
.parent .box.pool {
top: 90%;
left: 50%;
}
.parent .box.plant {
top: 55%;
left: 3%;
}
<div class="parent">
<div class="box plant">1</div>
<div class="box window">2</div>
<div class="box light">3</div>
<div class="box pool">4</div><img src="https://images.pexels.com/photos/4075088/pexels-photo-4075088.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260" alt=""/>
</div>

You can achieve this with percentage positioning. For example,
In the parent div
position: relative;
In the child div
position: absolute;
top: 50%;
left: 30%;
Now the child div will always position itself 50% from the top and 30% from the left of the parent div. It does not matter what size the parent div is. I suggest you take a parent div and put the image and texts inside it.
Your example website also uses this technique.

Another technique would be using HTML canvas. But for something simple like this, HTML canvas would be overkill.
I am trying to build a layout where I have two divs in the background that span 100% of the page and then a full height wrapper div of a smaller size for content that sits centered on the page. The issue I am having is while I can get the wrapper to sit correctly on top of the top div; I cannot get it to behave correctly on the bottom div. Here is an example:
html,
body {
height: 100%;
margin: 0 !important;
padding: 0 !important;
}
.index-banner {
background: #265f7a;
height: 60%;
width: 100%;
}
.wrapper {
background: #444;
height: 200%;
margin: 0 auto;
position: relative;
top: -60%;
left: 0;
right: 0;
width: 50%;
}
.footer-bg {
background: #888;
height: 250px;
position: relative;
top: -85%;
left: 0;
right: 0;
width: 100%;
z-index: -1;
}
<body>
<div class="index-banner"></div>
<div class="wrapper"></div>
<div class="footer-bg"></div>
</body>
Now the issue with the above code is by using a negative positioning, then I leave a massive gap at the bottom of the page. However I have also tried:
Using an absolute positioning on the wrapper div. Works perfect in keeping the page the correct size however then the bottom div floats to the bottom of the viewport
Using a faux method of making the bottom div look like a full width div by using a background image on body; unfortunately this just sticks it to the bottom of the viewport instead of the bottom of the page due to no content being between both background divs.
Now I have thought about keeping the wrapper occurring naturally between both of the background divs so they do not overlap at all and then put divs inside of those background divs lined up with the wrapper however that becomes a bit of a nightmare that I want to avoid because then I have to struggle to try and align the content that overlaps them as each of those "section divs" would have to be split into two (imagine trying to make a paragraph look like one because it is spread between two divs).
So my question is - am I going about this the wrong way and overlooking something that I could be doing differently to make this work?
I've been handed a bunch of pages to code up with weird irregular layouts. Below is an example of what I need to create.
The key points about this are;
The elements need to be positioned pixel perfect as per the mockups.
Upon window resize, all elements and the positions need to size down/up
proportionately.
The size of the container needs to resize proportionately also, because there will be more content under the layout.
Considering each element needs to have specific positioning, it's obvious to use absolute positioning. I also note that because the layout needs to stay proportionate, positioning needs to be done in percentages.
For images I can set the widths to be a percentage and height auto. And elements can be positioned with a percentage along the x axis.
But the problem arises when I need to position from the top.
If I declare an element to be say 20% from the top, this positioning won't change proportionately when I resize the page. Also, the containing block will need to have a declared height.
The only way I can see this working is with some javaScript trickery.
But this seems fussy for a seemingly simple layout. And it's not advisable to rely on javaScript to maintain a layout.
There must be a better solution, I've seen irregular layouts like this often.
I've looked into Flexbox, but I can't think of how it can help me in this situation.
How would you tackle this layout?
You can wrap everything in a wrapper that uses the "padding-bottom trick" to maintain its ratio based on its width. Because the height of the parent element is now dependent on the width of the document, all percentage values you give to top and bottom properties of child elements will be affected by the width of the page, instead of the height.
main {
position: relative;
width: 100%;
height: 0;
padding-bottom: 120%;
}
div {
background: red;
position: absolute;
}
.one {
width: 40%;
height: 40%;
top: 10%;
left: 40%;
}
.two {
width: 50%;
height: 20%;
top: 55%;
left: 15%;
}
.three {
width: 20%;
height: 30%;
top: 60%;
left: 70%;
}
<main>
<div class="one"></div>
<div class="two"></div>
<div class="three"></div>
</main>
Try using this trick to scale your container proportionally
<div class="container">
<div class="container-inner-wrap">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>
</div>
.container {
position: relative;
display: inline-block;
width: 75%; // Choose the width you want.
}
.container:after {
padding-top: [$height / $width * 100] %;
content: '';
display: block;
}
.container-inner-wrap {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
Where $height and $width are numbers - the value of the height and width you want your container to be. The real value you should put in there is what you get when you divide the ideal height by the width and multiply that by 100% (the unit is going to be %). What you get then is the aspect ratio of your container, and it will stay that size and shape no matter your browser size.
You can use that on all your boxes too, just make sure that you have that inner wrap that's absolutely positioned just inside. If I was building this layout, I'd use this trick for sure.
Here's an example of someone else using this: http://wellcaffeinated.net/articles/2012/12/10/very-simple-css-only-proportional-resizing-of-elements/
I'm essentially displaying a banner image on a page. At the base of that image is an overlay (the abs. pos. div) with a semi-transparent background image to make a "see through" effect. Everything is positioned properly and working fine except the overlay at a width of 100% expands outside of my container div. I've tried setting the overflow to hidden of the container div but that does not seem to work. My parent container has a position relative as well. This is responsive so the overlay with need to shrink and expand to the image width. Here's my code:
.hero-img-wrap {
position: relative;
margin-top: 35px;
padding-left: 15px;
padding-right: 15px;
}
.hero-img-wrap img {
width: 100%;
height: auto;
}
.hero-img-wrap .trans-overlay {
position: absolute;
bottom: 0;
z-index: 9;
height: 19px;
background-image: url('../images/semi_transparent_white.png');
width: 100%;
}
<div class="hero-img-wrap">
<img src="images/banner_image.jpg" alt="">
<div class="trans-overlay"></div>
</div>
I could pull this off with JQuery but I'd like to avoid that. For what it might be worth - this code is within a Bootstrap 3 column.
Since you've defined the height, why not a negative value
position: relative;
top: -19px;
Just a thought, heres a fiddle for ya
http://jsfiddle.net/g11yggap/
Try
Width:inherit;
On overlay div
