i noticed that in the following example, note the classes, i am using 960gs in case the classes css interfered
html
<section id="main" class="container_12">
<div class="grid_12">
<article>
...
css
header, footer, section, article, nav, aside { display: block; }
#main { background: #fff; }
i noticed that #main has a height of 0 in firebug. also if i do a
#main .grid_12 { background: #fff; }
it works
i noticed that if i use a div instead of section the css works
UPDATE
turns out that its because of the div.grid_12 or rather div.grid_x that causes the problem, if i remove that <div> it will work even if i am using <section>
<section id="main" class="container_12">
<div class="grid_10"> <!-- <<< this div -->
From the spec:
The section element is not a generic container element. When an element is needed for styling purposes or as a convenience for scripting, authors are encouraged to use the div element instead. A general rule is that the section element is appropriate only if the element's contents would be listed explicitly in the document's outline.
i found the answer, grid_x has float: left i need to clear it

I am trying to build a horizontal scrolling layout, composed of image blocks:
<div class="container">
<div class="item">
<img src="http://placehold.it/200x300">
</div>
<div class="item">
<img src="http://placehold.it/400x300">
</div>
<div class="item">
<img src="http://placehold.it/300x300">
</div>
</div>
I used display:inline-block and white-space: nowrap; properties to achieve this, and it does work but browsers don't seem to recompute block widths on resize?
Check here: https://jsfiddle.net/g597w3Lr/2/ and try resizing the browser..
Here is a screen grab to better understand what is my problem:
https://youtu.be/VxKo4gysc1o
At first all images are well positioned and i can scroll horizontally: perfect.
I then resize the browser
images are resizing, not the .item wrappers. White gaps appear :(
Basically i was expecting same feature as with vertical scrolling, i.e. adapting width depending on content size.
I actually dont even understand the logic here..
Is there any way to get over this?
Thanks!
Original answer
EDIT 2: Looking at your video I think the new approach is what you are looking for.
You have to display your divs with .item class as inline and remove your white-space: normal property.
.item {
display: inline;
height:100%;
}
Updated JSFiddle.
Explanation:
I am not an expert of CSS so if someone see some mistake please correct me.
When you display an element as inline-block as the official documentation says:
inline-block
Causes an element to generate an inline-level block container. The inside of an inline-block is formatted as a block box, and the element itself is formatted as an atomic inline-level box.
which means that the element that you display as inline-block acts like a block but you can set it inline (in the same line). This means that you can set a div (which is display: block as default) in a single line. You can also see it here:
The div element, short for division, is the block level generic container.
Also, inline elements cannot get height/width properties so this is the reason why when you display your divs with .item class as inline, they wrap the content but not get the height/width that they should correspond to take (from their parents in your case, as you put them with %).
If you display them as inline-block it does not changes anything about their default height/width properties. Just allows you to display them in a single line.
JSFiddle to see the three divs (inline/ inline-block / block, as default).
You will have to modify slightly your css
HTML
<div class="container">
<div class="item">
<img src="http://placehold.it/200x300">
</div>
<div class="item">
<img src="http://placehold.it/400x300">
</div>
<div class="item">
<img src="http://placehold.it/300x300">

CSS
html,body {
height:auto;
}
.container {
display: inline-block;
white-space: nowrap;
height:auto;
}
.item {
display: inline-block;
white-space: normal;
}
.item img {
width:100%;
height:100%;
}
Fiddle
check it see that's what you want ?
I manage your classes with border:solid 1px red;
and use width:100% in some classes.
also in class item:
width:100%;
https://jsfiddle.net/g597w3Lr/6/
I have markup that goes something like this
<div class='wrap'>
<div class='container'>
Body Container content
</div>
<div class='container'>
Footer Container content
</div>
</div>
I want to display a header containing, amongst other things, a logo above the first, body, container. This I accomplished by defining
.container::before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
The above works. The problem is that the logo ends up not onlyu above the body content but also above the footer content which is not quite the desired result. I have played around with various combinations of
.container::before:nth-of-child(1)
{
}
.container:nth-of-child(1)::before
{
}
but I haven't quite found the right syntax to target the ::before pseudo element for the first .container instance. I hope that someone here will be able to tell me how it should be done.
If the worst comes to the worst I can do it with a spot of jQuery but I would like to avoid that.
Would you consider using <main> W3 4.4.14 The main element and <footer> 4.4.9 The footer element per HTML5 elements with class of .container on each? That way you can reference/target those elements without psuedo elements
main::before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
This way the header/logo you are looking for would only appear above the first container only. Then if you need to apply pseudo elements to <footer> you could do something like:
footer::before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
OK so I'll add another answer because it doesn't appear that anyone has solved all of your issues.
First, there is a typo in your css: background-image(url(path/to/image.jpg) is missing the closing paren.
To do what you want, however, there is a simple css selector :). In your example, you try nth-to-child(), but the correct syntax for what you want is nth-child(). Look below for two options, with a working demo.
.container:first-child:before
{
display: block;
content: "Before Element";
/* other styling that you choose*/
}
/* the following selector will also work
.container:nth-child(1):before
{
display: block;
content: "Before Element";
}
*/
<div class='wrap'>
<div class='container'>
Body Container content
</div>
<div class='container'>
Footer Container content
</div>
</div>
Note that the display: block; part is so that the before content appears on it's own line, since :before elements by default are display: inline-block;.
I dont think that there is a way to making it work with nth-of-child, but it will definitely work with first-child (if you always need it only in the first element with class .container):
.container:first-child:before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
My first thought here is that there should be an additional class for the header, or use the <header> and <footer> elements in place of divs. For example:
<div class="wrap">
<div class="container header">
Header
</div>
<div class="container footer">
Footer
</div>
</div>
and
.header::before {
// stuff to make your logo
}
However, if for some reason you can't change the html, then the :first-child selector should work for your needs, as others have answered.
If you want to use nth-child() you need to add it to the parent of the element that you want to select. In this case .wrap.
.wrap:nth-child(1):before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
I was trying to parse from a complicated html page, but someone told me a better way is to inject my own css into that html. So I have the following situation:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css" />
</head>
<body>
<div>
layer one div
<div id="center">
layer two div
<div>
layer three div
</div>
</div>
</div>
</body>
</html>
As you can see the div with id is sandwiched between a parent div and a child div.
I wonder if it is possible to hide the parent and child, making the page only show layer two div line. I try doing
div { display: none; }
div#center { display: inline;}
but without success.
I am using the indent method now, thank you for all the help, guys! : )
Here is kind of a hack, but it works:
HTML
<div>
layer one div
<div id="center">
layer two div
<div>
layer three div
</div>
</div>
</div>
CSS
div {
text-indent: -9999px;
}
div#center {
text-indent: 0px;
}
div#center div {
display: none;
}
Fiddle: http://jsfiddle.net/fPdda/2/
As far as I know, there is no option to show element which is placed under hidden element. So CSS will not do the trick. The only possible option is use javascript, which move element which is supposed to be visible out of parent. This can be easily done with jQuery.
However I don't know why you need this and what you mean with word "parse". CSS will affect only what you see, but under "parse" I understand processing data - and for processing is not important how it is shown. Maybe if you specify more detailed what you need, I can help.
This method will not work. Sadly, because your displayed div is inside a hidden div, you're sunk if you're stuck with that markup. You could get fancy and use text-indent: -9999px instead of display: hidden, then text-indent: 0px on the one you want to show, but the negative indented elements will still take up vertical space. Alternately, you could use JS to duplicate the node and re-insert it into the DOM at a different point, maybe inside an element that isn't hidden.
var nodeToShow = document.getElementById('center').cloneNode();
nodeToShow.setAttribute('id', 'centerClone');
document.body.appendChild(nodeToShow);
I don't think that is possible. Hiding the parent div takes precedence on the child, so your child with id is visible but only in the scope of parent div which is hidden. In order to accomplish what you trying to do just wrap the parent text in a span and hide the span;
div span{
display:hidden;
}
div#center div{
display:hidden;
}
You can't hide a parent yet make a child element visible, it just doesn't work that way. I would suggest doing something like this:
<div class="layer-one">
<span class="layer-one">layer one div</span>
<div id="center">
layer two div
<div>
layer three div
</div>
</div>
</div>
.
div,
span.layer-one {
display: none;
}
div.layer-one,
div#center {
display: block;
}
I'm trying to convert my site from using tables to just using css and divs but I'm running into a lot of problems with trying to figure how to exactly do it, I've been looking for tutorials on centering a site with css and how to put divs side by side but I can't really find one that does both and I keep getting confused by how to exactly achieve this, I asked around a bit and I got told to use absolute positioning but still I can't really wrap my head around this.
So basically how would I arrange the 2 central div side by side while keeping the whole thing centered in the browser? The following image is the layout I'm trying to achieve:
the blue boxes are eventual other stuff I might want to put in them, such as a blog requiring again the use of side by side divs.
right now I have the following layout:
<div id="wrap">
<div id="banner"> banner </div>
<div id="navbar"> navigation links </div>
<div id="body"> stuff </div>
<div id="footer"> stuff </div>
</div>
General idea: http://jsfiddle.net/JjbJE/
A little specific but provide you a great adventure to learn HTML | CSS : http://jsfiddle.net/JjbJE/3/
float:left|right this property does the side by side trick
clear:both this property clear away the float property
Other things are pretty easy to learn, just head to W3Schools
First you need a main container to center everything. Then two separate divs. See the HTML below:
<div id="main">
<div class="box">Left Box</div>
<div class="box">Right Box</div>
<div class="clear"></div>
</div>
Here is the CSS you will need:
#main{
width:960px;
margin:0 auto;
}
.box{
width:450px;
float:left;
border:solid 1px #000000;
}
.clear{
clear:both;
}
Hope that helps.
Here's my general overview on converting to a CSS based layout - if you have a table based layout, this is a good plan - in the end you can do more, Google will like you more, and it's much cooler.
My strategy is to look at all the groups of things on your page. Whatever needs to go into a group together, put inside a div. Assign this div a class and/or id to style it. If the divs are grouped, put them together in a div too.
In your case, you have two chunks of content to group inside of divs. Style them to be the size and shape you like, background, border, whatever is needed. Then group them together in an additional div, and center it. This and the rest of the page content can go inside a container div, which will determine the width of the page, how it's aligned, etc.
One possibility is to have a centered wrapper class and contain the divisons inside of that:
<div class="wrapper">
<header></header>
<div id="middle">
<div class="main-article clearfix"></div>
<aside></aside>
</div>
<footer></footer>
</div>
Then to style, center the wrapper, float the aside and main-article:
.wrapper { width: 1024px; margin: 0 auto; /* the auto centers it */ }
header, footer, aside, { display: block; }
.main-article { width: 50%; float: right; }
aside { width: 50%; float: left; }
.clearfix:before, .clearfix:after { content: ""; display: table; }
.clearfix:after { clear: both; }
.clearfix { *zoom: 1; }
Note: This is untested, and uses the clearfix from the HTML5 Boilerplate.
Update 01.22.2014: This "Holy Grail Layout" has ben solved by Flexbox. Check out Solved By Flexbox for more information on recreating this layout (and many more).
Suppose my web page has a struture like this:
<body>
<div id="fee">
<div id="fi">
<div id="actual_content">
<p>Content</p>
<div id="some_important_stuff">Blah</div>
<p>More content</p>
<span class="and_another_thing">Meh</span>
...
</div>
<div id="fo>
...
</div>
...
</div>
<div id="fum">
...
</div>
...
</div>
<div id="fazz">
...
</div>
...
</body>
I want to create a print CSS style that hides everything except for the contents of actual_content.
My first attempt was like this:
body * {
display: none; /* Hide everything first */
}
/* Show content div and all of its ancestors */
body > #fee {
display: block;
}
body > #fee > #fi {
display: block;
}
body > #fee > #fi > #actual_content {
display: block;
}
/* Unhide contents of #actual_content */
#actual_content * {
display: block; /* Not ideal */
}
However, since there's no "display: auto" or "display: default", I mess up the styles of actual_content's items when I try to unhide them. I also don't like hard coding the path to actual_content since it might change.
You probably want to use the visibility property. W3Schools describes the difference between the display and visibility properties: the visibility property affects the visibility of an element without affecting its structure, i.e. the space it would normally occupy on the page.
on the top level div set visibility:hidden, then on the div you want set visibility:visible
You'll need to go in and target everything that you don't want to show up individually by setting display:none. If you can change class names, etc, you should un-nest the actual_content <div>, then add classes like hide_div to the other <div>s so they're easy to turn off.
I know your tags show you want a CSS solution, but the PrintArea jQuery plugin is perfect for your needs:
PrintArea sends a specified dom element to the printer, maintaining
the original css styles applied to the element being printed.
