Greetings
I have serius problem, I need to move div in div in a div, but it doesn't work.
My question is if there couldn't be some problems with negative margins or child element of element with margin problem.
It seems negative margin is collapsing with positive margin in child element.
The margin of child element is moving parrent element.
here is fiddle
of my problem.
What I want to achieve is that:
a. Article div is overlaping main heading, I tried to avoid using absolute position, so I went for negative margin.
b. Text is margined inside of an article div. From top.
<div class="container">
<div class="main-heading"><h1>Main Heading</h1></div>
<div class="wraper">
<div class="article">
<div class="text"><p>Text</p></div>
</div>
</div>
</div>
Also here is some of problem in css:
div {
width: 100%;
}
.container {
}
.heading {
}
.wraper {
margin-top: -100px;
height: 500px;
}
.article {
margin-top: 0;
height: 200px;
}
.text {
margin-top: 120px;
height: 50px;
}
As I said, margin of text element seems to move article element from top as well. It's me or where is the problem, and what's the solution or workaraund? Preferably even without absolute position, but if you really need to use them, don't worry, but clear it somehow so it can be used as part of column and wont interact with upper/bottom content.
Thank you verry much for your time
edit: picture of what I want to achieve
That black rectangle is wrapper,
cat is article
text is text, but the margins move whole article now.
I found a related toppic on this, it happens in all mayor browsers, and there is a simple solution on that. There is a must to use overflow attribute in CSS...
I used
overflow: auto;
On parrent element, and it worked.
Based on your comment and what I think you're asking:
<div class="image">
<p>PRESTO</p>
</div>
.image {
display:block;
position:relative;
background-color:grey;
width:300px;
height:200px;
}
p {
display:none;
position:absolute;
top:0;
width:100%;
text-align:center;
color:orange;
font-size:2em;
}
.image:hover > p {
display:block;
}

Simple one that I can't wrap my head around. Look at the code below; in my understanding of the box model, the 60px margin on #content should push the entire .main div down, and the .main div's margin should start 60px down the page, but in practice the .main margin overlaps with the #content margin (here's a codepen)
<head>
<style>
#content{
margin-top:60px;
}
.main{
margin-top:20px;
}
</style>
</head>
<body>
<section id="content">
<div class="main">
<h1>Here's some content</h1>
</div>
</section>
</body>
Why is this happening?
Edit: And what are some proposed solutions? Note that adding overflow:hidden to the parent element is one solution but it isn't an appropriate fix; if I put an h1 inside .main and try to put a top-margin on that, the same issue happens - and I don't want to be applying overflow:hidden to everything!
It's because of collapsing margins which you can read about here.
That is happening because you have not specified height of your content div. So when you give in something like .main in your #content div then the content div takes up the height of .main div because that is what the content requires.
So to make it a bit clear, if your .main div is taking up a height of 50px then #content will also be just 50px in height because you have not specified otherwise. So the margin-top of .main div is collapsing with .margin-top of #content.
This is default behavior of the box model as per w3c (reference)
Now to overcome this you need to float the elements as below
#content {
margin-top: 20px;
float: left;
width: 100%;
}
.main{
float: left;
width: 100%;
margin-top: 40px;
}

I have wasted an hour on this stupid problem. I have made projects and it worked. I deleted that code in rage.
I wanted to center an image but there was a heading above the image. So, i wrapped them in a div and gave them a id[x].
What i tried #x - margin:0 auto width:50%; margin:auto; width:50%; margin: 0 auto; width:50%; margin-left:auto; margin-right:auto; and changing positions to relative.
What worked [not wrapped in a div] -
img {
display:block;
height: 200px;
width: 200px;
margin: auto;
}
h1 {
color:blue;
text-align:center;
}
But this code had a problem as the image is clickable, the whole width of where the image was became clickable, i don't know why.
You cannot have a block element inside an inline element. The anchor that the image would be wrapped in is an inline element. When you turn the child into a block element it will make the anchor take the entire width of the line, because you don't have a width setting on the anchor.
To fix this issue, display:block; should be display:inline-block;
Use text-align: center to center the image.
#test {
text-align: center;
}
img {
display: inline-block;
height: 200px;
width: 200px;
}
h1 {
color:blue;
}
<div id="test">
<h1>Hi, I am guy!</h1>
<a href="#">
<img src="//lorempixel.com/200/200">
</a>
</div>
if I understand your problem you want to both center the header and image that are wrapped in a div. You do not want the entire area of the div clickable just the image. Below is a fiddle.
If the above is correct it seems you just need to add the a tag around the img tag and not the div itself.
<div>
<h1>Header</h1>
<img src="https://placeholdit.imgix.net/~text?txtsize=33&txt=200%C3%97200&w=200&h=200" />
</div>

UPDATE:
display: block will take up the width of the parent element everytime, as others have said use inline-block.
Only apply size to the img tag, and apply display to the a tag. The wrapper class with text-align: center is actually taking care of centering the img as well.
Here is the updated fiddle:
https://jsfiddle.net/gward90/7s45osxa/3/
Here is also your fiddle updated with my suggestions
https://jsfiddle.net/gward90/aLxecdk6/5/
I have a CSS
.nav {
width: 200px;
line-height: 50px;
float: left;
}
.content {
margin: 0px 0px 0px 230px;
}
.container {
border: 1px solid red;
}
And here is the HTML
<body>
<div class="container">
<div class="nav">Some text
<br>more text
<br>even more text
</div>
<div class="content">
<h1>Home</h1>
<p>Text paragraph</p>
</div>
</div>
</body>
This gives me menu on the left and the content on the right. And a red box around the content on the right, but only the half menu on the left.
But I would like to have the red box also around the complete nav-div Can anyone help?
Thanks

Add overflow:auto to your container div's CSS:
.container {
border: 1px solid red;
overflow:auto;
}
jsFiddle example
Floating the child div removes it from the flow of the document and the container essentially collapses as if it didn't exist. Adding the overflow restores the behavior you're after.
I think this is a quick fix if you float your container it should solve the problem your having. See here http://jsfiddle.net/1540sscj/
.container {
border: 1px solid red;
float:left;
width:100%;
}
Floating an element removes it from the normal flow of the page with one side effect being that its parent's dimensions won't expand to fit it.
So, what you need to do is clear the floated item. The best way to do this, without using additional markup or using the overflow property, which may cause other issues, depending on your layout, is to use the :after pseudo class on the parent element, like so:
.nav{
width:200px;
line-height:50px;
float:left;
}
.content{
margin:0px 0px 0px 230px;
}
.container{
border:1px solid red;
}
.container::after{
clear:both;
content:"";
display:block;
height:0;
width:0;
}
<body>
<div class="container">
<div class="nav">Xalsdk fjaskldfj alskdfj asädf<br>asdf<br>asdf</div>
<div class="content">
<h1>Home</h1>
<p>Bla bla.</p>
</div>
</div>
</body>
More information on clear
More information on pseudo elements
Best way imho would be to add a div like:
<div style="clear:both;"></div>
Under your floating elements: FIDDLE
This way you don't need to use oveflow:hidden on your container that may give you problems once you have more stuff in your project.
Also you shoudn't use a margin-left for your content as the previous element is already floating left. The best practise if you want to add some margin between nav and content would be to make your content float left as well and then use margin left (the exact size you want) with respect of the nav and not with the left of the window.
Finally, if you don't want to add the clear:both div to the html you could add somethign like
.content:after {
content:'';
display:block;
clear: both;
}
it's a bit less browser (old ones) compatible but cleaner
You have to add overflow:auto to .container in your css
Check my js fiddle
Also the css that modified.
.container {
border: 1px solid red;
overflow:auto;
}
Description of property overflow from MDN
The overflow property specifies whether to clip content, render
scrollbars or just display content when it overflows its block level
container.
this is my html (for example)
<div id="wrap">
Some relative item placed item
<div id="fixed">hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii</div>
</div>
here is my css:
#wrap{
float: left;
position: relative;
width: 80%;
background:#ccc;
}
#fixed{
width:inherit;
}
I want to make the second div that is 'fixed' to have same width as the first 'wrap'. I tried a lot, but i can't do it.
Is it possible to do this without any javascript?
Any suggestion..please.
here is the fiddle for this:
http://jsfiddle.net/sris/tktdf1kk/
You need to leave your width alone. Divs already expand 100% of their containing div. The reason your text is not wrapping is because it's all one word. Add the CSS:
#fixed {
word-wrap: break-word;
}
I have a page in which a header consists of three divs - one that's floated to the left, one that's floated to the right, and one that's in between them. I'd like for that central div to be centered, yet sadly float: center doesn't exist and I can't just float it to the left and add padding as it'd have to change depending on the window size.
Is there something simple I'm overlooking? Or how would I do such a thing?
Update:
In addition, I'd like to find a way of centering that middle div in the space between the divs in case that looks better.
If you have two floated divs, then you know the margins. The problem is that the float:right div should be put before the middle div. So basically you will have:
left-floated | right-floated | centered
Now, about the margins: usually you can just use margin:0 auto, right? The problem is that right now you know the values of the margins: floated divs! So you just need to use:
margin:0 right-floated-width 0 left-floated-width
That should work.
Years later edit
Meanwhile, a new toy is in town: flexbox. The support is fairly good (i.e. if you don't need to support lower than IE 10) and the ease of use is way over floats.
You can see a very good flexbox guide here. The example you need is right here.
Indeed, the important part is that the centered div come after the left and right divs in the markup. Check out this example, it uses margin-left: auto and margin-right: auto on the centered div, which causes it to be centered.
<html>
<head>
<style type="text/css">
#left
{
float: left;
border: solid 1px red;
}
#mid
{
margin-left: auto;
margin-right: auto;
border: solid 1px red;
}
#right
{
float: right;
border: solid 1px red;
}
</style>
</head>
<body>
<div id="left">
left
</div>
<div id="right">
right
</div>
<div id="mid">
mid
</div>
</body>
</html>
Here's a JS Bin to test: http://jsbin.com/agewes/1/edit
Usually you can use flexbox instead of floats:
https://jsfiddle.net/h0zaf4Lp/
HTML:
<div class="container">
<div>left</div>
<div class="center">center</div>
<div>right</div>
</div>
CSS:
.container {
display: flex;
}
.center {
flex-grow: 1;
}
The element with the centered content needs to be specified after both floated elements. After that, simply set the middle element to text-align: center. The text in the centered element will squeeze in between the floats.
See here:
http://jsfiddle.net/calvintennant/wjjeR/
Try this (make sure to use better class names):
.left {
float:left;
width:200px;
}
.right{
float:right;
width:200px;
}
.center {
overflow:hidden;
zoom:1;
}
The center div will fit between the two floats.
If you want to create a gutter between that centered div and the two floats, then use margin on the floats, not on the center div.
Because of "zoom", the CSS will not validate, but that layout will work in IE 5.5 and 6.
Note that source order is important here: the two floats must come first, then your "centered" div.
In some cases, you have a limitation and cannot change the page markup by moving the middle div after the right-floated div. In that case, follow these instructions:
For container: position: relative
For middle div: position: absolute; left: [containerWidth - middle-width / 2]
I hope you got the idea.
A simple solution without having to change the order of the divs (sometimes we can not do this) could be an absolute positioning for the center div as follows:
.container {
position: relative;
}
.container div {
width: 200px;
background: red;
}
.left {
float: left;
}
.right {
float: right;
}
.center {
position: absolute;
top: 0;
left: 0;
right: 0;
margin: auto;
}
<div class="container">
<div class="left">left</div>
<div class="center">center</div>
<div class="right">right</div>
</div>
