Given this example:
<div class="main">
<div class="container">
<div id="banner-message">
<p>I want to be hidden</p>
<p id="el">I want to be visible</p>
</div>
</div>
</div>
the .main and the .container have position:relative, the #banner-message and the #el have position: absolute because I need to move them around inside the .container which has overflow: hidden with the purpose of hidding all elements that overflow, except the #el, and here is my question:
Given this structure and positioning is it possible to make only #el visible when it overflows the .container?
heres's a fiddle as repro:

Is there an easy way (without manually setting any heights) to make sure a parent element always wraps/contains a child, even if the child has been relatively positioned?
<div style="background-color: red;">
<div style="background-color: pink; position: relative; top: 20px">
one.
</div>
</div>
<div>
two.
</div>
In the example above the "one." div flows out of its parent and overlaps/hides the "two." div, but my desired effect is to have the parent div contain the whole of the child and the "two." element flowing underneath.
top is used to position element so that it has no effect on the surrounding elements. Use margin-top if you want to affect the parent as well, otherwise top doesn't affect the other elements.
<div style="background-color: red; display: flex;">
<div style="background-color: pink; position: relative; margin-top: 20px">
one.
</div>
</div>
<div>
two.
</div>
In the example image, I have navigation. Example code below shows potential markup. If the image and the text below need to move together (slide side to side), how can I anchor the position the navigation using only CSS. I suspect that I'll have to rely on some JavaScript without knowing heights of elements, but I would rather not have to.
To be clear, the navigation here appears to be centered, but they are not. They need to be floated at the bottom of an arbitrary image height.
UPDATE
Example code (see CodePen):
<div class="carousel">
<div class="indices">
<div class="dot"><div class="ghost">Carousel slide 1</div></div>
<div class="dot"><div class="ghost">Carousel slide 2</div></div>
<div class="dot"><div class="ghost">Carousel slide 3</div></div>
</div>
<div class="gutter">
<div class="content">
<div class="img"><img src="https://cdn.pixabay.com/photo/2016/05/25/13/55/horses-1414889_1280.jpg" alt="Horses"></div>
<div class="text">This text content can really be any arbitrary height, so it wouldn’t work to just use negative margins on the navigation, unfortunately.</div>
</div>
<div class="content">
<div class="img"><img src="https://upload.wikimedia.org/wikipedia/commons/d/de/Nokota_Horses_cropped.jpg" alt="Other Horses"></div>
<div class="text">Also, images can be arbitrary heights.</div>
</div>
<div class="content">
<div class="img"><img src="http://maxpixel.freegreatpicture.com/static/photo/640/Water-Turtle-Nature-Reptile-649667.jpg" alt="Turtles"></div>
<div class="text">Turtles</div>
</div>
</div>
<div class="nav">
<a class="item prev" href="#" aria-label="Previous carousel story"></a>
<a class="item next" href="#" aria-label="Next carousel story"></a>
</div>
</div>
My code is very flexible; I can move things around if need be.
Have you tried to use position: relative and position: absolute (like in this simple example)? You wrap your image slide and bullet navigation in a div where you set the position to relative. Then set the navigation wrapper to absolute position (bottom: 0 to place it at the bottom of the parent div). It will normally stay in place even if the image changes as the height of the parent div will depend on the img height.
.outer-div {
position: relative;
}
.bullet-nav {
position: absolute;
bottom: 0;
left: 50%;
transform: translateX(-50%); /* to center nav */
}
I'm pretty much trying to copy what you see in the following picture. I have three sections. Between section 1 and section 2 (the blue section) you can see the white arrow-box. That's what I can't place properly without messing things up.
Now I already got this "working" by placing the arrow box inside the blue section, and then gave both the arrow-box and the blue section absolute positions, and then gave the arrow box some minus margin from top. The problem with this is, that for some reason I can't create section 3 that is supposed to come after the blue section. I can't place anything under the blue section if its position is absolute. If I give the blue section a relative position, things obviously start working normally again, but then the arrow box gets out of place and something like this happens:
My code looks something like this, HTML:
<section id="first-section">
<!-- bunch of stuff here -->
</section>
<section id="blue-section">
<div class="arrow_box">
<p>How can I help you?</p>
</div>
</section>
<section id="third-section">
<!-- More stuff here -->
</section>
CSS:
#blue-section {
position: relative;
}
.arrow_box {
position: absolute;
width: 500px;
height: 100px;
left:0;
right:0;
margin-left:auto;
margin-right:auto;
margin-top: -50px;
}
OK, then here you go:
HTML
<section class="container" id="first-section">
<!-- bunch of stuff here -->
</section>
<section class="container" id="blue-section">
<div class="arrow_box">
<p>How can I help you?</p>
</div>
<div class="col"> <img src="http://www.andalucesdiario.es/wp-content/uploads/2014/09/tyrion_lannister.jpg" alt="" /> </div>

<div class="col"> <img src="http://www.andalucesdiario.es/wp-content/uploads/2014/09/tyrion_lannister.jpg" alt="" /> </div>
</section>
<section class="container" id="third-section">
<!-- More stuff here -->
</section>
CSS:
.container{position:relative; background:#ccc; padding:40px; width:100%; height:auto; min-height:100px; text-align:center;}
#blue-section{background:#06c}
.arrow_box{position:absolute; background:#f9f9f9; position:absolute; top:-50px; left:50%; margin-left:-100px; height:100px; width:200px;}
.col{width:30%; padding:1%; display:inline-block;}
.col img{width:200px; height:200px; border-radius:50%;}
As you can see, you weren't that wrong, you just need to understand that absolute positioning requires a relatively positioned div in order to be positioned itself.
See the possible values so you understand (from Mozilla MDN)
static
This keyword lets the element use the normal behavior, that is it is laid out in its current position in the flow. The top, right, bottom, left and z-index properties do not apply.
relative
This keyword lays out all elements as though the element were not positioned, and then adjust the element's position, without changing layout (and thus leaving a gap for the element where it would have been had it not been positioned). The effect of position:relative on table-*-group, table-row, table-column, table-cell, and table-caption
elements is undefined.
absolute
Do not leave space for the element. Instead, position it at a specified position relative to its closest positioned ancestor or to the containing block. Absolutely positioned boxes can have margins, they do not collapse with any other margins.
fixed
Do not leave space for the element. Instead, position it at a specified position relative to the screen's viewport and doesn't move when scrolled. When printing, position it at that fixed position on every page.
sticky
The box position is calculated according to the normal flow (this is called the position in normal flow). Then the box is offset relative to its flow root and containing block and in all cases, including table elements, does not affect the position of any following boxes. When a box B is stickily positioned, the position of the following box is calculated as though B were not offset. The effect of ‘position: sticky’ on table elements is the same as for ‘position: relative’.
And if you made it here, you get a free fiddle

I Want to place a div over another div without using height in pixels.I have used this code
<div style="position: relative;height:78px;">
<div style="width:425px;position: absolute;top: 0;left: 0;">
Content for First div
</div>
<div style="z-index:10;position:absolute;top: 0;left: 0;">
Content for Second div
</div>
</div>
The first div content will change dynamically . So is their any way to put height auto some thing like in parent div
both child divs are taken out of the flow, so the parent will have no natural height (which normally is "stretched" by it's children).
since you have pre-loaded data on the first child div, make the second match to it.
HTML:
<div id="parent">
<div id="firstChild">
Content for First div
</div>
<div id="secondChild">
Content for Second div
</div>
</div>
CSS:
#parent{
position:relative;
}
#firstChild{
width:425px;
}
#secondChild{
width:425px;
position:absolute;
top:0;
bottom:0;
}
NOTE: watch out for collisions in your styles, i used ID here. replace accordingly
height: 100% should make it the height of the parent div which is 78px;
<html>
<head>
<style type="text/css">
div
{
background-color:#ccc;
}
</style>
</head>
<body>
<div>
<div style="float: left;">This is a text inside a div element.</div>
<div style="float: right;">We are still in the div element.</div>
</div>
</body>
</html>
Why isnt the background color showing up in between those 2 divs?
When you float elements you should provide the width of the floated elements. Otherwise you may encounter unexpected behaviors accross different browsers.
Check this tutorial, there is good info on floating in css. [link is dead]
Basically, if you provide an overflow:hidden; to the container div and provide width to the floated elements, your problem will be solved.
<div style="overflow: hidden;">
<div style="float:left; width: 300px;">Some text</div>
<div style="float:right; width: 300px;">Some text</div>
</div>
Similarly, you can add another div wherever you want to normalize the flow ike this:
<div>
<div style="float:left; width: 300px;">Some text</div>
<div style="float:right; width: 300px;">Some text</div>
<div style="clear:both;"></div>
<div>This div will be at the same place
as if the previous elements are not floated</div>
</div>
Both will work :)
EDIT
Another method which I use frequently in these days is to float the first element and set a margin-left to the following element. For instance:
<div>
<div style="float: left; width: 300px;">Some text</div>
<div style="margin-left: 300px;">Some text</div>
<div style="clear: both;"></div>
</div>
The advantage of this method is that the following element (the second div in this case) does not need a fixed width. Plus, you may skip the third div (clear: both;). It's optional. I just add it in case that the floated div is longer in height than the second div since if you don't add it the parent div will always get the height of the second div.
Just set the container div to overflow: hidden;.
If you set elements to float they won't be in the normal 'flow' of the document anymore.
div { background: #ccc; overflow: hidden; }
And you didn't even made a freehand circle ;)
A floating element doesn't affect the size of the parent, unless the parent specifically contain the children using the overflow style.
Your outer div has the same background colors as the child divs, but the height of the parent is zero, so you don't see its background.
It's because both the divs are floated so the containing divhas no height. If you were to add a third child div whic wasn't a float, give it a height of 0 and clear:both you should see the background colour appear.
The white space you are showing is a body part and you set the background color to the div but not in the body. That is the reason the body part is empty.
To color the empty part you should add following code:
<html>
<head>
<style type="text/css">
div
{
background-color:#ccc;
}
body{
background-color:#ccc;
}
</style>
</head>
<body>
<div>
<div style="float: left;">This is a text inside a div element.</div>
<div style="float: right;">We are still in the div element.</div>
</div>
</body>
</html>
You can change the body background color by changing the background color in body style.
