I have a layout like so:
<div class='foo'>
<div class='bar'>
<div class='baz'>
Content stuff...<br/>
Content stuff...<br/>
Content stuff...<br/>
Content stuff...<br/>
</div>
</div>
</div>
with CSS like so:
.foo{
position:absolute;
left:20px;
top:20px;
}
.bar{
width:0px;
border-left:1px solid blue;
border-right:1px solid yellow;
}
.baz{
padding-left:35px;
padding-right:27px;
}
... a pretty standard way to get a full height columns. But I also need bar to be a fixed width (in this case 0px). Is there any way to get the content div, baz, to have its old width (when bar had auto width), and still keep bar full height?
Using CSS alone, I don't think so; At least none I can't think of.
Why not set the width to auto in CSS, using jQuery you can set the width to a variable, and then you can set the width to 0px...
That way you've got a variable that you can set .baz to.
Am I making sense?

I have a square image within .img-container. Sometimes it takes a few seconds for an image to load and the .img-container collapses and only takes the full height when the image loads. However, I would like it to keep the full height (as if the image is there) while the image is loading.
I would've easily done this by setting a min-height on img-container class, however it's a fluid grid and the image is responsive (notice bootstrap's img-responsive helper class) which makes it hard to set the min-height to an appropriate value for different screen sizes (although achievable with media queries as a last resort).
Solving this by putting a placeholding image sounds like an overkill (especially performance wise on mobile). Also, not sure what would load first then, the placeholder image or the actual image.
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-4">
<div class="card">
<span class="img-container thumbnail clearfix">
<img alt class="pull-left img-responsive" src="http://...">
</span>
<div class="caption">
<a href="http://.." class="card-title lead">
Some text
</a>
</div>
</div>
</div>
EDIT DUE TO COMMENT
If you do not specify a source at all (not even a dummy, temporary one), the browser will not even try to "guess" the image's height, and so it collapses. If you know the ratio of the image (it's obviously 1:1 in case of a square picture), you can use the following trick to preoccupy the space, and scale the image along with the div.
Set the following CSS:
.test-div-inner {
padding-bottom:100%;
background:#EEE;
height:0;
position:relative;
}
.test-image {
width:100%;
height:100%;
display:block;
position:absolute;
}
Then you can use the following HTML:
<div class="test-div-inner">
<img class="test-image" src="http://goo.gl/lO9SUU">
</div>
Here is the working example: http://jsfiddle.net/pQ5zh/3/
Note that the fiddle contains another div element, this is only required if you would like to give it all a padding or border, since the padding-bottom calculates the padding in pixels based on the width of the div INCLUDING THOSE PARAMETERS, which is NOT the effect we want to achieve (the image would be a little taller than it should be).
For non-square images:
If you would like to change the ratio of the picture, just change the padding-bottom of the container div accordingly. For example, if you would like to place an image with a ratio of 2:1, change the padding to 50%. To keep it short: the ratio of the container div's width and padding should always be equal to the ratio of the image's width and height.
There is an easy way to do exactly this, but it only works for square images.
Specify the width of the image (using CSS) to be 100%. This way the browser will automatically assume that the image height is the same as it's width, and preoccupy the place.
http://jsfiddle.net/pQ5zh/2/
.test-image {
width:100%;
}
Note: There is a way to achieve this for non-square images too, but that is a bit more complicated.
EDIT: See above.
Ok, assuming all images are square, we can do it. Add an extra div around your image like this:
<div class="img-container">
<div class="image-wrap">IMAGE HERE</div>
</div>
Then we want CSS along the lines of
.img-container {
position:relative;
background: #ccc;
width:200px; /* Remove this width */
color:#000;
}
.img-container:before{
content: "";
display: block;
padding-top: 100%;
}
.image-wrap {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
See this in action:

You'll want to remove the width set in .img-container
test http://o7.no/U5w2EV
The structure for this is:
<div id='container'>
<div id='play'>▶</div>
<div id='res'>RES</div>
<div id='bar'>test</div>
<div id='time'>0</div>
</div>
The styles are:
for #container
#container
{backgroundColor:'#CCCCCC',
position:'absolute',
bottom:'-40px',
width:'100%',
height:'40px'}
for Buttons #res and #bar
#res , #bar
{width:30px;
height:30px;
border:1px solid #DDDDDD;
margin:5px;
font-weight:bold;
cursor:pointer;
float:left}
for #time
#time
{float:'left',fontSize:'16px',margin:'12px 5px'}
Note: the width of the container of the container (where it takes the 100%) changes dinamically.
How to set the CSS as to the #bar div fill all the space remaining from the other divs?
You've got incomplete code posted above. It's also formatted incorrectly (css).
But I "think" if you remove the css float on the inner <div>'s and instead make them display: inline-block; you should be able to declare CSS width: percentages on the inner <div>'s and have them fill your container.
You can add another <div> at the bottom after <div id='time'> and set the style clear:both
I couldn't do it with CSS in a satisfactory manner so I added a JavaScript listening to resize attempts which would keep it the right size mathematically.
I am trying to add two divs inside the parent div, which has a button inside each div.
I need to fix the width in pixels only for the second div and the 1st div should be having width in % so that the button inside the 1st div should be covering the entire space of the browser.
I need all the widths in % and also I don't want to change either html structure and css because it is already implemented so i just need changes in css property.
Here is my demo
http://jsfiddle.net/zuyyT/2/
P.S : When I scale the browser, the second div is coming in next line. Please scale it and check once.
Fiddle is working on and off ... you can go either one of two ways; using floats (need to change the order of your markup) or positioning - like such ...
<div class="block">
<div class="block_right"> <span>last button</span> </div>
<div class="block_left"><a href="" class="scButton score" > <span>Lorem ipsum</span></a></div>
</div>
and your CSS ...
.block {
display:block; background-color:#FFC; width:100%; float:left; height:30px
}
.block_left{
background-color:#C93; margin-right: 150px;
}
.block_left a{
background-color:#CCC; border-radius:4px; padding:4px; width:100%; display:block
}
.block_right{
float:right; width:130px; background-color:#CC9
}
... using position, you'll need to add position:relative to .block and then right:0 to .block_right; keep the margin on .block_left
Using positioning, you won't need to change the order of the elements in your markup (should that be an issue).
This may be what you require. :-)
.block_right{
position :absolute;
right:0;
top:0;
float:right; width:130px; background-color:#CC9
}
If you give your block_left a width:100% and then use margin-right:-130px; you can leave your html exactly as it is.
The negative right margin leaves space on the right hand side for other elements to fit into even though the element has a 100% width.
This is happening because of the width of right div..u gave 100% to the parent and 80% to the first child..so,when the browser size is 500px(say),the first child will occupy 400px(80%) of it...And when u give 130 px to the second child,it'll come to the next line..that's pretty obvious coz it doesn't have enough space in the first line...so it should be <=100px(for this example)...
I am new to Css. I have an HTML page.
<body>
<div id="viewer">
<div id="flow">
<img src="images/beatles.jpg">
<img src="images/blink.jpg">
<img src="images/doves.jpg">
<img src="images/flash.jpg">
<img src="images/floyd.jpg">
<img src="images/jurassic.jpg">
<img src="images/naked.jpg">
<img src="images/prodigy.jpg">
<img src="images/xx.jpg">
<img src="images/zabiela.jpg">
</div> <!--end of <div id="flow"> -->
<ul>
<li id="left">
Left
</li>
<li id="right">
Right
</li>
</ul>
</div> <!--end of <div id="viewer"> -->
</body>
Each image is 200x200. Now i am confused with the css of it. Here i show it step by step
#viewer {
width:700px;
height:220px;
padding:100px 0 30px;
margin:auto;
border:1px solid #000;
position:relative;
}
You define width and height of main Div. Define padding, means each element that is place inside div will place 200px from top, no sapce from left and right, 30px space from bottom of div. Also i want to ask here we define position relative. Is it relative with respect to body or html?
We didn't define the #flow div width and height. So it calculated by the padding. The #flow div width is same as the #viewer width, but place 30px below from top of #viewer div, it's height is 190px, place 30px above from bottom. Please tell me if i am wrong.
#flow:after {
content:"";
display:block;
height:0;
clear:both;
visibility:hidden;
}
Now we are defining content that we want to enter after the #flow div. We set it's visibility hidden, means it is there, taking up the space but not showing. Is it? The thing that i want to ask here is this, that we are using clear:both here. What are we clearing here? we didn't set any float property in the #viewer div?
Now comes the confusing part
#flow img {
display:block;
margin-left:-165px;
position:relative;
top:-15px;
left:245px;
float:left;
background-color:#fff;
}
Now we are setting images, that are in the #flow Div. First thing that i notice which is confusing that if i set it's top property to 1px. Then it align with respect to # flow div. Which is fine because it's position is relative, and it is inside #flow div, so it is aligning with respect to #flow div.
But when i change it's left property to 1px. Then it goes beyond the both divs(#viewer and #flow). Align itself somewhere between the mid of scree left corner and left of div. Why it is happening. If it's position is relative, then it should remain inside the #flow div. This is my confusion.
Also images are shrink to accommodate inside the div. I think it's because of the dov size. That each image is 200x200. Our #flow width is 700px only.
Another thing we set margin-left:-165px;. Right now images are arrange horizontally and also shrink to accommodate in the div. But if i change to margin-left:165px;. Then images are expand vertically and all images are shown. Images are not shrink. Also we set top:-15px;. When are we set values in negative?
It's not an assignment or homework. I am just practicing and i want to know how things are working. Here are the remaining css
#viewer li {
list-style-type:none;
position:absolute;
bottom:10px;
}
#left {
left:20px;
}
#right {
right:20px;
}
Thanks
A good start to find out how the css works is to install firefox with firebug. In firebug, you can hover over elements to see their styling.
Secondly, I would place the images in li tags for better organization.
I currently have a div with width:auto to fill the entire screen width but I want to put a side bar on the right hand side.
When I float the width:auto div left and fixed width div to the right it goes under instead.
I'm basically looking for something similar to what reddit have with there search bar on the right width the content auto adjusting to the page width.
Thanks
You can make it like this:
Say you have those 2 divs inside a parent container, which expands to fit the page:
<div id="container">
<div id="autowidth">text expands her...</div>
<div id="fixed">This is a fixed column</div>
</div>
In your CSS:
#container {
width:100%;
border:1px solid black;
padding-right:200px;
}
#autowidth{
width:100%;
background-color:red;
float:left;
}
#fixed{
width:200px;
background-color:green;
float:right;
margin-right:-200px;
}
Basically, the parent container holds everything together. It has a padding of 200px (the width of the right col), so that its content doesnt goes beyond that point. In turn, the right col has a margin of -200px, so that it forces the boundaries imposed by the parent padding and places itself always at the foremost right. The other div, actually, now has only the spaces provided by the parent container, constrained by its padding, so its 100% would be, in fact, (100% - (parent's padding)). You can see a working result of this here: jsfiddle.
I'm pretty sure there might be more elegant solutions out there, so bear with me.
if you want to give a background, like it were 2 cols, you can go for the classical 'faux columns' background (see example at a list apart )
You don't strictly need a container div. I did css inline for brevity.
<div style="float:right; width:14em; background-color:#CCC;">
<p>This div is fixed-width.</p>
</div>
<div style="background-color:#EEE; margin-right:14.5em;">
<p>This div is auto-width.</p>
</div>
The answer doesn't work for me, I think it's outdated. Now you have to specify box-sizing: border-box for padding to count to width, but thanks for inspiration. This is my solution.
#autowidth {
float:left;
width:100%;
padding-right:200px;
box-sizing:border-box;
}
#fixed {
float:right;
width:200px;
margin-left:-200px;
}
