I have a question:
There are 3 divs. 2 of them should have their background-images and their position is to the 2 sides of user-area. (one to the right, and one to the left). The 3rd div should be over them and full-width.
How can I do this with css?
Make either those two divs or the third div positioned absolutely. Assign a z-index to the third div higher than for those other two.
(Well, as far as the talk about CSS can go without example)
<style>
div.holder-for-left-and-right
{
width: 100%;
overflow: hidden;
position: relative;
}
div.left
{
float: left;
width: 100px;
height: 50px;
background: url(...) no-repeat;
z-index: 1;
}
div.right
{
float: right;
width: 100px;
height: 50px;
background: url(...) no-repeat;
z-index: 1;
}
div.on-top-of-them
{
position: absolute;
top: 0;
width: 100%;
height: 50px;
z-index: 2;
}
</style>
<div class="holder-for-left-and-right">
<div class="left">I am leftM</div>
<div class="right">I am right</div>
<div class="on-top-of-them">I am over them</div>
</div>

Hello I need to position an image as in the example. Theoretically it looks like it is positioned over 2 seperate boxes with different background colors, that is the goal, but practically it is not possible, at least for me. How to solve the problem?
Usually you'd do this with flex and vertical alignment, but since you want specifically the image to be between boxes i'd say absolute is the way to go here
.card {
display: block;
margin-left: 80px; /* image width + 20px */
}
.header, .image-container {
display: block;
margin: 0;
}
.header h1 {
margin: 0;
}
.image-container {
height: 1px;
position: relative;
}
.image-container .image {
display; inlnie-block;
width: 60px;
height: 60px;
border-radius: 50%;
background: purple;
position: absolute;
top: -50%;
left: -10px;
transform: translateY(-50%) translateX(-100%);
}
<div class="card">
<div class="header">
<h1>Header</h1>
</div>
<div class="image-container">
<div class="image"></div>
</div>
<div class="header">
<h1>Header 2</h1>
</div>
</div>
The simplest solution will be using a combination of an of z-index and position:absolute.
*A small suggestion if you may encounter the problem: you must use z-index with specifying the position (position: static will not work)
img {
width: 100px;
height: 100px;
z-index: 99;
position: absolute;
}
div {
background-color: black;
z-index: 1;
width: 200px;
height: 100px;
position: absolute;
top: 10px;
left: 5px;
}

I have this simple HTML code, but make me frustrated because it can't center vertically :
<div class="outer">
<div class="inner">
Hello World
</div>
</div>
and here's my CSS :
.outer {
position: relative;
height: 350px;
}
.inner {
position: absolute;
height: 100px;
top: 50%
}
the .inner div is really center vertically, but based on top side of it. because of top: 50%, what I want is this .inner div really centered vertically on top of .outer. how to do that?
You can center your element using css3 even if you don't know the dimensions.
.inner {
position: absolute;
height: 100px;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
}
Since you know the height of both elements you can set your top to top: 125px;
(350 - 100) / 2.
UPDATED WITH JQUERY

Actually an easy way to center a absolute div is to use margin: auto;
section {
width: 100%;
height: 800px;
position: relative;
background: #eee;
}
div {
width: 500px;
height: 300px;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
margin: auto;
background: orange;
}
<section>
<div></div>
</section>
I added borders to differentiate clearly
Is this you want?
http://plnkr.co/edit/JRct1x95gnIUl8jITzG0?p=preview
.outer {
position: relative;
height: 150px;
border : 1px solid #f00;
}
.inner {
position: absolute;
height: 80px;
top:0;
bottom:0;
margin:auto;
border : 1px solid #0f0;
}
You could use this CSS trick to make the div vertically centered (and optionally horizontally as well). This works for a parent div of any height and width, as long as they are specified.
.inner {
position:absolute;
// The height and width of the element have to be set for this to work
height:100px;
width:100px;
// Setting the top and bottom to 0px as well as the margins to auto
// causes the div to be centered vertically.
top: 0px;
bottom: 0px;
margin-top: auto;
margin-bottom: auto;
// To also center the div horizontally, do the same for
// left, right and the margins.
left: 0px;
right: 0px;
margin-left:auto;
margin-right:auto;
}
Note that this solution only works when the height of the parent div is known beforehand and is specified. So the parent element needs to have height:100px or whatever amount of pixels you need it to be. Also the height can't be percentual, meaning that if the height of the parent div is declared as height:50%, this will NOT work.
The inner div can actually have a
You can set it by line-height property set it to the height of the div as in your code it should be line-height: 100px;
.outer {
position: relative;
height: 350px;
background: gray;
}
.inner {
position: absolute;
height: 100px;
line-height: 100px;
background: blue;
}
<div class="outer">
<div class="inner">
Hello World
</div>
</div>
I have 2 divs in a row (with inline-blocks). One of them has a fixed width and the other one is supposed to automatically fill the left space. How can I do that?
My favorite solution is to use padding on the container block and absolute position on the fixed with object:
.wrapper {
padding-left: 100px;
position: relative;
}
.stay {
width: 100px;
position: absolute;
left: 0;
top: 0;
/* for demo */
height: 50px;
background-color: pink;
}
.fit {
width: 100%;
/* for demo */
height: 50px;
background-color: red;
}
HTML:
<div class="wrapper">
<div class="stay"></div>
<div class="fit"></div>
</div>
I have two containers both are relative and both are set float right. My target is that, the left container to give height 100% of the screen and in a fixed position. But when I do it, all the other elements get broken. Suggestions kindly appreciated.

<div class="outleftcontainerunder">
</div>
<div class="maincontainer">
<div class="innermaincontainer">
<div class="articlebutton"></div>
<div class="discussionbutton"></div>
<div class="editbutton"></div>
<div class="searchbar"></div>
</div>
</div>
body
{
margin: 0;
padding: 0;
}
.outleftcontainerunder
{
width: 175px;
height: 250px;
background: green;
float: left;
position: relative;
}
.maincontainer
{
width: calc(100% - 175px);
height: 1000px;
float: left;
position: relative;
}
If you remove the float on the left container, and move the main container to the right it should work how I think you want it to.
See: http://jsfiddle.net/VpxeC/2/
.outleftcontainerunder /*I want this div to be in position fixed and height as 100% of the screen. But when I do it, there is a chaos*/
{
width: 175px;
height: 250px;
background: green;
position: fixed;
height: 100%;
}
.maincontainer
{
width: calc(100% - 175px);
left: 175px;
height: calc(100% + 50px);
float: left;
position: relative;
}
Check this out: jsFiddle Demo

width: 175px;

What I am trying to is have a header image centered on the top with a different color background on either side, dynamically filling the rest of the page. The structure would look like this:
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Center"></div>
<div id="Header_Right"></div>
</div>
The Header_Center is of 960px and the Header_Left and Header_Right should fill either side of the image to the edge of the page and change width as the page width changes.
I can not get the CSS to work properly.
I assume you want those 3 divs to fill each with different content, the outsides filled fluidly or multiline. Otherwise the answer could be much 1) more simple. I also assume that the center div defines the total height of the header.
Given these two assupmtions, still a few different scenarios are thinkable of which I will give 4 examples from which you can choose the best fitting solution.
The HTML is exactly yours.
The CSS looks like:
#Header_Container {
width: 100%;
position: relative;
}
#Header_Left {
position: absolute;
left: 0;
right: 50%;
margin-right: 480px;
}
#Header_Right {
position: absolute;
left: 50%;
right: 0;
margin-left: 480px;
top: 0;
}
#Header_Center {
width: 960px;
position: relative;
left: 50%;
margin-left: -480px;
}
Now, you could change behaviour of left and right with a few extra styles:
height: 100%;
overflow: hidden;
See demonstration fiddle.
1) When the sides may be partially invisible outside the browser window (in case which you would align content in de left div to the right, and vise versa), then I suggest the solution in this fiddle demo which does not require absolute positioning at all so that any content below the header is properly cleared in all circumstances.
You must fix it using padding and box model + position : relative - it can be done without HTML Change
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
And CSS ( 100px is for example )
#Header_Container{ overflow: hidden; height: 100px; }
#Header_Container *{ box-sizing: border-box; height: 100%; }
#Header_Left{ width: 50%; padding-right: 480px; }
#Header_Right{ margin-left: 50%; width: 50%; padding-left: 480px; position: relative; top: -100% };
#Header_Center{ margin: 0 auto; width: 960px; position: relative; top: -200%; }
Example is here http://jsfiddle.net/ZAALB/2/
EDITed incorrect example
If I got you right then this might be a possible solution.
#container {
width: 100%;
height: 150px;
}
#left {
position: absolute;
left: 0;
width: 50%;
height: 150px;
background-color: #FF0000;
}
#right {
position: absolute;
right: 0;
width: 50%;
height: 150px;
background-color: #0000FF;
}
#center {
position: absolute;
left: 50%;
margin-left: -480px;
width: 960px;
height: 150px;
background-color: #888888;
}
#left basically says that the element will be positioned absolute and attached to the left side with a width of 50%. Same applies to #right just for the right side.
#center positions the element absolute pushed 50% to the left and then with a negative margin of width/2 which in your case would be 480px to position it in the center.
The order of the elements in the HTML is important for this hack.
<div id="container">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
The #center DIV must be the last element if you don't want to work with z-indexes.
Here's a fiddle to test it.
HTML:
<div id="Header_Container">
<div class="Header_Side" id="Header_Left"></div>
<div class="Header_Side" id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
CSS:
#Header_Container {
position: relative;
width: 100%;
}
#Header_Container > div {
height: 158px; /* height of the image */
}
.Header_Side {
position: absolute;
width: 50%;
}
#Header_Left {
left: 0;
background-color: blue;
}
#Header_Right {
left: 50%;
background-color: green;
}
#Header_Center {
position: relative;
width: 158px; /* width of the image */
margin: 0 auto;
background-image: url('...');
}
Also see this example.
This works, but you need to change your HTML: http://jsfiddle.net/gG7r7/1/
HTML
<div id="header_background_container">
<div id="header_left"></div>
<div id="header_right"></div>
</div>
<div id="header_content_container">
<div id="header_content"><p>Content goes here</p></div>
</div>
CSS
#header_content_container {
position:absolute;
z-index:1;
width: 100%;
height: 100%;
}
#header_content {
width: 960px;
margin: 0 auto;
background: red;
height: 100%;
}
#header_left {
background: white;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
#header_right {
background: black;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
