What's the best way to achieve this:
I have two elements, both absolutely positioned and I want the child to overlap horizontally, even though its parent has overflow-x: hidden.
FIDDLE
.parent {
position: absolute;
z-index:1;
height: 100%;
min-height: 300px;
overflow-y:auto;
overflow-x:hidden;
width: 200px;
background: #ccc;
}
.child {
position:absolute;
z-index:2;
width: 300px;
height: 100px;
top: 30px;
left: 10px;
padding: 10px;
background: #555;
color: white
}
Add a third div that is a parent of both. Position both items absolutely within the outer parent.
<div class="outer-parent">
<div class="parent">
</div>
<div class="child">
</div>
</div>

There are lots of card to be showed and I need to show menu when I hover one of the cards.
I use position: absolute; for menu and use position: relative; for the card, but why the scrollbar appeared when I hover on the card ？

The scrollbar has nothing to do with your positioning, it is a result of overflow: auto; on your .box element.
overflow: auto; will show a scrolling bar if a child element overflows its parent container where overflow: auto; is set.
Seeing as the .box parent-element has a fixed size value height: 240px; while its child element .menu has height: 400px;, it will cause a scrollbar to appear because there is an overflow of 160px.
While #Yong is correct with document flow in his answer with the position: absolute; property, seeing as you have fixed height and width on all your elements, position: absolute; doesn't actually do anything in this exact reproducible example.
If I understand your problem correctly, a simple solution to your problem if you want to keep the fixed width and height on your .box element, you can simply disable the scrollbar by applying display: none; to the .box pseudo-element ::-webkit-scrollbar.
(NOTE: As of February 28th, 2022 this is still not supported in Firefox).

Example with no positioning properties & -::webkit-scrollbar
.box {
height: 240px;
width: 200px;
border: 1px dashed red;
overflow: auto;
}
.box::-webkit-scrollbar{
display: none;
}
.card {
height: 120px;
width: 120px;
border: 1px solid blue;
/*position: relative;*/
}
.menu {
display: none;
height: 400px;
width: 200px;
/*position: absolute;
top: 0;
left: 0;*/
background: linear-gradient(orange, pink);
}
.card:hover .menu {
display: block;

If you want to remove overflow altogether, you can apply overflow: hidden; to .box.
Keep in mind the fixed height of 400px on the .menu element will not apply as the fixed height of 240px on the .box element will hide the remaining 160px. I hope this solves your problem, but a little more detail would help!
absolute
The element is removed from the normal document flow, and no space is
created for the element in the page layout. It is positioned relative
to its closest positioned ancestor, if any; otherwise, it is placed
relative to the initial containing block. -MDN
.menu is positioned absolute therefore it is positioned relative to .card which is the closes positioned ancestor to it.
relative
The element is positioned according to the normal flow of the
document, ... -MDN
And because .card is positioned relative it would still take space and position according to the normal flow of the document. Therefore, it would still be taken into consideration whether the .box or its parent would overflow or not.
with set position: absolute; for .menu and position: relative; for .card you able to change the position of .menu with top bottom left right properties relative to its first positioned (not static) ancestor element( .card position ).
but in your question, the absolute or relative position is not the cause of the scrollbar appear . The reason is the owerflow property .
the default value for owerflow is visible that create no owerflowing . And you created the scrollbar by setting it auto because the size of menu is larger than card.
.box {
height: 240px;
width: 200px;
/* overflow: auto; */
border: 1px dashed red;
}
.card {
height: 120px;
width: 120px;
border: 1px solid blue;
position: relative;
}
.menu {
display: none;
height: 400px;
width: 200px;
position: absolute;
top: 0;
left: 0;
background: linear-gradient(orange, pink);
}
.card:hover .menu {
display: block;
}
<div class="box">

How can I achieve the styling shown in the picture? Consindering the following scenario: I got 2 nested div elements, by which the parent is "relative positioned" and the child is "absolute positioned"! And the child div is always "fixed to the bottom" of the body element, when browser is scaled. I don't get this to work...
Here is the code, where I am using padding-bottom: 100%. But this is not a good solution! Is there a way to realise this with only CSS 2.1 API?
body {
min-height: 100%;
background-color: grey;
}
.parent {
height: 70px;
width: 440px;
left:200px;
background-color: blue;
position: relative;
}
.child {
display: block;
position: absolute;
width: 100px;
right:0px;
background-color: yellow;
padding-bottom: 100%;
}
<body>
<div class="parent">
<div class="child">Fix to bottom</div>
</div>
</body>
Don't take 2nd div as child. You want it to stick to bottom and parent div's height will disturb it while scalling.
I hope this helps :)
body {
min-height: 100%;
background-color: grey;
}
.parent {
height: 70px;
width: 400px;
left:100px;
background-color: blue;
position: relative;
top:70px;
}
.another-parent {
display: block;
height:60%;
position: absolute;
bottom:0;
width: 100px;
right:22%;
background-color: yellow;
}
<body>
<div class="parent"></div>
<div class="another-parent">Fix to bottom</div>
</body>
Recently I have come across a problem for which I am not finding any appropriate solution.
Below is the image which gives an idea of what i am trying to achieve:
The div shown by the arrow is the mark of the problem which i am finding a solution for.
The problem is I want the div to be extended to full screen.
This div is inside a parent div who has a fixed width due to which i am not able to extend my image to full screen.
Have tried giving overflow to parent but isn't working.
I have tried below solution which is working to a certain extent but need a reliable solution.
width: 100%;
left: 0;
position: absolute;
margin-left: calc(-31.5vw);
align-content: center;
Could someone please provide some solution to this?
html, body
{width: 100%; height: 100%; overflow: hidden;}
#parent{
display: block;
background-color: yellow;
border: 1px solid red;
position: fixed;
width: 200px;
height:100%;
}
#child1{
background-color: red;
display: block;
border: 1px solid yellow;
position: absolute;
width: 100vw;
margin-left: calc(200px - 100%);
//top:0px
}
<div id="parent">parent with position: fixed
<div id="child1">child wrapper (uncomment top to fit the parent wrapper)</div>
</div>
use Viewport Sizes so it will cover the whole page (vw and vh)
#first {
width: 100px;
height: 100px;
background:gray;
position: fixed;
top: 0;
left: 0;
}
#second{
width: 100vw;
height: 100vh;
background:blue;
position:absolute;
}
<div id="first">
<div id="second">
something
</div>
</div>
The below code snippet should work, if I understand your question correctly. Setting the width of the child div to 100vw makes the div 100% of the width of the viewport (window).
Also note that in order to get the child to start at the left of the viewport and not the left of the parent, I gave the child a position of absolute and a left of 0. Because the parent is not positioned, it starts the left of the child at the left of the viewport (the closest positioned ancestor).
#parentDiv {
width: 250px;
height: 250px;
margin: 0 auto;
background-color: orange;
border: 2px solid red;
}
#childDiv {
/* 100vw is 100% of the viewport width. */
width: 100vw;
height: 50px;
background-color: lightblue;
box-sizing: border-box;
border: 2px solid green;
position: absolute;
left: 0;
}
p {
text-align: center;
}
<html>
<body>
<div id="parentDiv">
<p>Parent</p>
<div id="childDiv"><p>Child</p></div>
</div>
</body>

I've stumbled upon some unexpected behaviour when testing a layout in Firefox. It seems that when a parent is set to display:table-cell and position:relative, its children do not respect the parent width when positioned absolutely and given 100% width. Instead, the child width is set to the parent's parent width. I've recreated this issue with a fiddle:
http://jsfiddle.net/D6Rch/1/
which is structured as:
<div class="table">
<div class="cell-1">
<div class="content-1">this must be positioned absolutely</div>
<div class="content-2">as these divs will be overlapping</div>
</div>
<div class="cell-2">
<div class="advert">fixed width advert</div>
</div>
</div>
.table {
width:600px;
height:400px;
border:3px solid black;
display: table;
position: relative;
table-layout: fixed;
}
.cell-1 {
width: auto;
display: table-cell;
background: yellow;
position: relative;
margin-right:10px;
}
.cell-2 {
margin-right:10px;
width: 100px;
display: table-cell;
background: pink;
position: relative;
}
.content-1 {
position: absolute;
top: 10px;
width: 100%;
background: lightgreen;
z-index: 5;
}
.content-2 {
position: absolute;
top: 50px;
width: 100%;
background: lightblue;
z-index: 5;
}
.advert {
position: relative;
border: 1px solid red;
}
It functions as expected in Chrome & Safari, but not on Firefox. Question is, why does this happen? And is there a workaround for this or should I take an altogether different approach?
Thanks in advance,
This is a known bug in Gecko. See the Gecko Notes here - https://developer.mozilla.org/en-US/docs/Web/CSS/position
So, you'll have to wrap you content divs in another positioned div. Like so
http://jsfiddle.net/D6Rch/4/
<div class="cell-1">
<div class="wrapper">
<div class="content-1">this must be positioned absolutely</div>
<div class="content-2">as these divs will be overlapping</div>
</div>
</div>
.wrapper {
position: relative;
}
I have a div inside a div, the child both being centered in its parent and bigger than the parent making it overflow equally on both sides of it. The child has another div inside it with some text.
<div class="outer">
<div class="inner">
<div class="text">
testing testing
</div>
</div>
</div>
css:
.outer
{
width: 400px;
height: 400px;
background: beige;
margin: 0 auto;
}
.inner
{
width: 600px;
height: 200px;
background: pink;
position: absolute;
left:0;right:0;
margin: auto;
}
.text
{
margin-left: auto;
margin-right: auto;
width: 400px;
}
http://jsfiddle.net/msVVD/4/
Now, if the document width is narrowed by resizing the browser window, or in the jsfiddle case, resized by dragging the handle between "JavaScript" and "Result", the text will not stay on the same horizontal position, but "travel" to the right.
Why?
You need to set a min-width to the body (or parent container in which the absolutely positioned element is aligned according to) like so
body
{
min-width: 600px;
}
This will prevent the absolutely positioned from traveling
FIDDLE
You are not positioning the .inner element relatively to the .outer one. Add position: relative to .outer.
Changes in your CSS:
.outer
{
width: 400px;
height: 400px;
background: beige;
margin: 0 auto;
position: relative;
}
.inner
{
width: 600px;
height: 200px;
background: pink;
position: absolute;
left:0;right:0;
margin: auto;
margin-left: -100px;
padding-left: 100px;
}
