I am trying to put simple divs and arrange them, but my child div disappearing from parent div even though I am using parent div with relative and child div with absolute positioning. I want connect_us_01 and registeration divs insideheader_block1. I am working towards responsive webdesign. Many thanks.
JSFiddle
<div id="header">
<div id="header_block1">
<div id ="registeration">reg</div>
<div id ="connect_us_01">social media</div>
</div>
<div id="header_block2">
<div id="crown_logo">logo</div>
<div id="nav">navigation</div>
<div class="contact_No_01">020324234233</div>
</div>
</div>
css
#header {
position: relative;
width: 100%;
background-color: #ff6a00;
}
#header_block1 {
position: relative;
margin: 0 auto;
width: 90%;
background-color: pink;
}
#header_block2 {
margin: 0 auto;
width: 90%;
position: relative;
background-color: aqua;
}
/*----social media & connect us block*/
#connect_us_01 {
position: absolute;
width: 300px;
height: 50px;
right: 0;
background-color: blue;
}
#registeration {
position: absolute;
left: 1px;
width: 200px;
height: 50px;
background-color: brown;
}
Elements with position: absolute are taken out of the content flow, meaning they have no inherent height. Since the children have no height, the parent gets no height either, rendering the children invisible. You could resolve it by giving the parent a static height (as in, for instance, height: 100px), but that's not very practical and not responsive at all.
What you're looking for isn't position: absolute; it's float: left and float: right. Apply those properties to the children and give the parent overflow: hidden (or whatever method of clearing floats works best with your layout) and it'll work just fine.
To show block you refering to just add to #header_block1 a height parameter also.
#header_block1 {
position: relative;
margin: 0 auto;
width: 90%;
height: 50px;
background-color: pink;
}

I have a div element wrapping other div elements like so:
<div style="overflow:hidden">
<div id="a"></div>
<div id="b"></div>
</div>
I have other css rules that manage the dimensions of the outer div. In my actual code, I want to position the div#a exactly 10 px below the outer div. However, I want div#b to still be cut off by the outer div's overflow:hidden.
What is the best way to achieve this?
Method 1
A good way to do it is by setting the overflowing element to position:fixed (which will make it ignore the parent overflow), and then positioning it relative to the parent using this technique:
.parent {
position: relative;
.fixed-wrapper {
position: absolute;
.fixed {
position: fixed;
}
}
}
One caveat is that you cannot have any of the top,right,left,bottom properties set on the fixed element (they must all be default 'auto'). If you need to adjust the position slightly, you can do so using positive/negative margins instead.
Method 2
Another trick I recently discovered is to keep the overflow:hidden element with position:static and position the overriding element relative to a higher parent (rather than the overflow:hidden parent). Like so:
http://jsfiddle.net/kv0bLpw8/
#wrapper {
width: 400px;
height: 50px;
position: relative;
z-index: 1000;
left: 0px;
top: 0px;
}
#wrapper #insideDiv {
width: 400px;
height: 50px;
overflow: hidden;
position: absolute;
z-index: 2000;
left: 0px;
top: 0px;
}
#wrapper #a {
position: absolute;
height: 30px;
width: 100px;
bottom: -40px;
z-index: 1000;
left: 0px;
}
<div id="wrapper">
<div id="a">AAA</div>
<div id="insideDiv">
<div id="b">BBB</div>
</div>
</div>
The easiest and most convenient way is to wrap your container div inside another div and set position: relative on the external div.
.outer-container {
position: relative;
height: 50px;
}
.container {
background: gray;
overflow: hidden;
height: 50px;
}
#a,
#b {
height: 100px;
width: 100%;
}
#a {
background: green;
position: absolute;
top: 60px;
}
#b {
background: red;
font-size: 60px;
}
<div class="outer-container">
<div class="container">
<div id="a"></div>
<div id="b">Cut off</div>
</div>
</div>
as people said, the element must be presented outside the parent in order to be not cropped. But you can do this with JavaScript to achieve the similar concept without having to change your actual markup:
function breakOverflow(elm) {
var top = elm.offset().top;
var left = elm.offset().left;
elm.appendTo($('body'));
elm.css({
position: 'absolute',
left: left+'px',
top: top+'px',
bottom: 'auto',
right: 'auto',
'z-index': 10000
});
}
then pass the element you want to exclude from the cropping of its parent:
breakOverflow($('#exlude-me'));
I have a parent div that contains two children, side by side. The first child is an image that must be height 100% and 58% width, margin auto and overflow hidden. The second child contains text, and the length of the text determines the height of the parent. This is a template for several pages, with different length of text, and therefore different parent height. Is it possible to do what I'm trying to do without using JS? Thanks for your input! Code below.
HTML:
<div id="product-summary">
<div class="product-image-container">
<img />
</div>
<div id="product-details">
<h3 class="product-title"></h3>
<div class="product-description"></div>
</div>
</div>
CSS:
.product-image-container {
position: absolute;
top: 0;
left: 0;
width: 58%;
height: 100%;
overflow: hidden;
img {
position: absolute;
top: 0;
left: 50%;
margin: auto;
transform: translateX(-50%);
min-width: 100%;
height: 100%;
}
}
#product-details {
float: right;
border: solid thin #777;
height: ~"calc(100% - 2px)";
width: 41%;
text-align: center;
}
The problem is your #product-details is floated, which creates a new BFM (block formatting context), and the parent gets collapsed.
I suggest you read more about BFMs here: http://yuiblog.com/blog/2010/05/19/css-101-block-formatting-contexts/
There are several ways to fix this:
You could clear the parent, a way to do that is by adding overflow: hidden; to the #product-summary element.
You could remove the float: right from #product-details, and use flexbox to align it instead.
I don't know any preprocessor wizardry, but using inline-block works good, as well as keeping positioned absolute elements wrapped in a relative parent for control. It wasn't mentioned how the image is displayed, so I assume aspect ratio unchanged and no cropping.

I do not understand whats wrong with my code. I mean, section element has the height, display value of my DIV element is definitly block and i really dont know how it works and how to combine these two elements differently positioned. Please give me your solutions and advices to learn something new today.
div {
position: relative;
margin: 0 30%;
}
div section {
position: absolute;
top: 0;
right: 0;
left: 0;
height: 100px;
background-color: yellow;
}
hr {
height: 2px;
background-color: blue;
}
<div>
<section></section>
</div>
<hr>
You want your hr on the bottom of the first div, right ?
However, this is not working because the parent div have an default height: auto property.
This mean that the parent div will have the height of his children.
When you set a position: absolute on a child, you are breaking this system.
The parent will no longer take care of his child.
So, if you want to make it works, you have two solutions:
- set a custom height (height: 100px) on the parent div (not good)
- remove the absolute position on the child section (default :position: relative)
div {
position: relative;
margin: 0 30%;
}
div section {
height: 100px;
background-color: yellow;
}
hr {
height: 2px;
background-color: blue;
}
<div>
<section></section>
</div>
<hr>
Your element has height set to AUTO. If you want to change your div height you need to write this in css.
div {
position: relative;
margin: 0 30%;
height: 200px;
background-color: red;
}
I think This is because your div has no height itself that's why it is not visible and it is increasing according to its child element which is section and is in absoulute position. I am not sure what you are up to but If you want to show the section inside the div along with the div's height the you must include the css for your div .
I provided an assumption solution for you hope it helps you
div {
position: relative;
margin: 0 30%;
background-color: green;
height: 150px;
}
section {
position: absolute;
top: 50px;
right: 0;
left: 0;
height: 50px;
background-color: yellow;
}
div hr {
height: 10px;
background-color: red;
}
<html>
<head>
</head>
<body>

<p>your div</p>

I have this following chunk of my page.
Style:
.featuredcontainer {
width: 450px;
height: 700px;
margin-left: auto;
margin-right: auto;
position: relative;
right: 160px;
top: 30px;
border: 1px groove grey;
}
.navcontainer
{
margin-left: auto;
margin-right: -8px;
position: relative;
top: 75px;
height: 600px;
width: 300px;
}
And example HTML:
<div class="featuredcontainer">
content
</div>
<div class="lessonnavcontainer">
menu
</div>
When the page is displayed. the navcontainer is to the right of (as it should) but under the featuredcontainer. When I move the navcontainer up using relative positioning, it looks right, but there is a bunch of empty space at the bottom of the page. What do I do?
Surround your two divs with a "wrapper" div like so:
<div id="wrapper">
<div class="featuredcontainer">content</div>
<div class="lessonnavcontainer">menu</div>
</div>
Then to center them, add margins to the wrapper:
#wrapper { margin: 0px auto; }
Then to have the two divs be side by side, add a float:
.featuredcontainer { float: left; }
.lessonavcontainer { float: left; }
In order for the centering to work, you need to declare a width on the wrapper:
#wrapper { width: 800px; }
Put both the nav and the featured containers into another wrapper div.
HTML
<div class='wrapper'>
<div class="navcontainer">
menu
</div>
<div class="featuredcontainer">
content
</div>
</div>
And get rid of all the relative positioning. Relative positioning is not recommended for basic layout issues like this. Use floats instead. The wrapper should have a fixed width, which allows it to be centered properly with margin: 0 auto.
CSS
.wrapper{
width:752px;
margin: 0 auto;
overflow:auto;
}
.featuredcontainer {
width: 450px;
height: 700px;
float:left;
border: 1px groove grey;
}
.navcontainer{
float:left;
height: 600px;
width: 300px;
background:#ff0;
}
JSFiddle http://jsfiddle.net/5w5SC/
Use the float property. Using float, css can position divs next to each other horizontally.
.featuredcontainer {
width: 450px;
height: 700px;
margin-left: auto;
margin-right: auto;
position: relative;
right: 160px;
top: 30px;
border: 1px groove grey;
float: left;
}
.navcontainer
{
margin-left: auto;
margin-right: -8px;
position: relative;
top: 75px;
height: 600px;
width: 300px;
float: left;
}
Thats a starting point, try to use float left or float right and see what happens. Fiddle with it until it looks exactly how you want it.
To get them side-by-side you need to add the float attribute in the CSS. To get them to resize with page width you need to add relative widths to them. To center them on the page (horizontally) you need to put the divs inside a relative positioned div in the html. Here is a fiddle. http://jsfiddle.net/Ne5zs/
Be sure to introduce a clearfix (there are many versions of this technique) on any floated object; then center their containing block element using margin: 0 auto.
I'm tidying up another developer's work who seems to have done a shoddy job with the CSS.
There is the main "wrapper" div on the page, and inside this is a logo and images for the navigation. The images are using "position: absolute" and using the CSS "top" property to offset them. However, Firefox and IE seem to start their offset from a different point, meaning the logo is about 100px above where it should be in IE.
Is this an IE CSS bug or known thing?
Example in question: http://barry.cityjoin.com/mccamb/
If you want to position elements absolutely within a wrapper using top, right, bottom and/or left, the position of the wrapper has to be set as relative explicitly. Otherwise the absolute elements will get positioned within the view port instead.
A little working example:
<style>
.wrapper
{
position: relative;
height: 100px;
width: 800px;
}
.absoluteLogo
{
position: absolute;
top: 10px;
left: 10px;
height: 60px;
width: 80px;
}
.absoluteElement
{
position: absolute;
top: 80px;
left: 320px;
height: 20px;
width: 80px;
}
</style>
<div class="wrapper">
<div class="absoluteLogo">Logo</div>
<div class="absoluteElement">Element</div>
</div>
Another possibility would be to position the absolute elements using margins:
<style>
.wrapper
{
height: 100px;
width: 800px;
}
.absoluteLogo
{
position: absolute;
margin: 10px 0 0 10px;
height: 60px;
width: 80px;
}
.absoluteElement
{
position: absolute;
margin: 80px 0 0 320px;
height: 20px;
width: 80px;
}
</style>
<div class="wrapper">
<div class="absoluteLogo">Logo</div>
<div class="absoluteElement">Element</div>
</div>
The result is the same and should be working across all browsers.
