You see tons of sites with their content very nicely centered, like dribbble.com for example. Even when the window is resized, the content stays centered and when it hits against the side of the page, stops.
I would really like to get this behavior on my website but I'm not really sure how to go about the CSS to make this happen... I'm aware of the position property and using percentages for the left/right positioning but it doesn't seem to be quite that simple.
Can someone help me figure out how to do something like this?
The standard practice is to have a div that wraps your centered content, such as...
<div id="container">
...everything you want to center
</div>
And the in your CSS:
#container {
width: 970px;
margin: 0 auto; /*first value the margin for top and bottom, auto puts automatic margins in the left and right to center the content*/
}
I'm aware of the position property and using percentages for the left/right positioning but it doesn't seem to be quite that simple.
It's simpler.
selector-that-matches-a-container {
width: <some length>
margin: auto;
}
Maybe with this CSS:
.content {
position:absolute;
left:100px;
right:100px;
}

I'm trying to implement a basic image viewer using HTML and CSS, where the image remains centered in the page, except for when it's too big to fit. In that case, the user should be able to scroll to see the rest of the image with no margins. If only one dimension is too big to fit, the other dimension remains centered. There is nothing else on the page other than the image.
However, the size of the image needs to be specified by a scaling factor so that I can enlarge or shrink it relative to its original size. This means I can't use an explicit width/height in pixels or size it relative to the size of the page. I've tried adjusting its transform css property, i.e. transform: scale(2.5) but that generally causes the top of the image to be cut off. I've also tried doing this by making the image's display property by set to inline-block and its height property set to auto so that I can set its width to the percentage I want it to be scaled by, but I can't figure out how to keep it centered on page as described in the above paragraph.
How can I accomplish this? So far I've tried around a dozen different ways of centering an element on the page, and none of them result in this exact behavior I'm shooting for. For example, I've used flexboxes to keep the image centered horizontally and vertically, but as soon as it grows too tall to fit, (again) the top of the image gets cut off.
You can use flexbox and center with margin to obtain this:
body {
min-height:100vh;
margin:0;
display:flex;
}
body > img {
margin:auto;
}
<img src="https://picsum.photos/500/500?image=1069" >
And in case you don't want scroll apply max-height/max-width:
body {
height:100vh;
margin:0;
display:flex;
}
body > img {
margin:auto;
max-width:100%;
max-height:100%;
}
<img src="https://picsum.photos/500/500?image=1069" >
there are several ways to achieve horizontal and vertical alignment. However, they are usually done separately and in different ways. You can have a look at W3Schools, they do a few tutorials on each:

Also if you are willing to use bootstrap (makes everything much easier, especially centering) you can have a look at the following link:

Below is a quick method on for centering. Credit goes to: This Post with some minor improvements from myself.
.outer {
display: table;
position: absolute;
height: 100%;
width: 100%;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
margin-left: auto;
margin-right: auto;
width: 400px;
text-align:center;
/*whatever width you want*/
}
<div class="outer">
<div class="middle">
<div class="inner">
<h1>The Content</h1>
<p>Once upon a midnight dreary...</p>
</div>
</div>
</div>
I am trying to position a footer under #cont, but inside the #container.
I tried making it so that when there is more content in #content, it would keep the footer inside the div, and allow me to scroll the page, but I got lost. Any idea how I should do it?
http://jsfiddle.net/a9jv7/
As you can see, more content will push it down(because it's not inside the other div, but if it's not inside, I can't set the footer to always be on the bottom of the page)
You can change the floating elements to display: inline-block, so you have more control over them and the container will adapt to their height.
#footer {
background-color:#FFA500;
text-align:center;
max-width:960px;
width: 100%;
}
The example: http://jsfiddle.net/frapporti/TPbCG/
EDIT:
In general, I'd really like to advice you against the use of floating elements for layout, as they were pushed beyond they original intended use from the very beginning, and now we have flex who does magic :)

http://jsfiddle.net/Cerebrl/ZkQnD/
If I understood what you want to achieve correctly, than this is one way to do it:
http://jsfiddle.net/a9jv7/1/
On #container add:
border-bottom:30px solid transparent; // used to add spacing bottom
margin-bottom:-30px; // used to add spacing bottom
overflow:hidden; // to give the container height, because it has none since the elements inside it are float-ed; (google clear-float).
So I know this is another centering question but I've been roaming around Google and SO for a couple days now without a solution so I'll ask now.
What I'm trying to do is horizontally center a fluid section element with a max width that has absolutely positioned elements inside it. The problem is, as you can see in my jsFiddle, the margins take up 50% of the available space with the other 50% used by the section. What I would like to do is keep the section perfectly centered but make the margins get smaller as the browser window closes in while keeping the section from re-sizing until the edges of the window gets to it.
I'd like to keep from using any table, table-cell solution because I read on CSS-Tricks that absolutely positioning elements inside table cells can be a real pain.
Edit Basically, the goal is to have the content take up as much space as possible without resizing until the view port width forces the content to be responsive.
Thank you for any bump in the right direction.
HTML:
<section id="wrapper">
<section id="content">
<p>Absolutely positioned imgs, btns, etc. go in here</p>
</section>
</section>
CSS:
#wrapper {
position:absolute;
width:50%;
height:300px;
margin-left:25%;
margin-right:25%;
outline:1px solid red;
}
#content {
position:absolute;
width:100%;
height:100%;
max-width:500px;
background:rgb(225, 112, 75);
}
You can use
#content {
display:inline-block;
text-align:center;
}
to center your elements that will have a display:inline-block; property too.
EDIT: Now that I've better read your question, you can also use
#content {
margin:0 25%;
}
to center your second section.
here's your fiddle updated. As you can see by this fiddle everything is centered AND responsive now.
EDIT-2: Maybe you want to add some media query to reach your goal. Just add something like this at the end of your CSS file:
#media screen and (max-width:720px){
#content{width:100%; margin:0px;}
}
this says that when screen reaches the width of 720 and under, #content (and every ID/CLASS you put in there) will behave as declared.
NOTE that #media queries are not crossbrowser, you may want to add a script to make them work on every browser, I find respond.js a nice tool to do this job.
Also note that the #media queries must be placed at least under the default properties that you are about to change on screen resizing, that is why is suggested to add them at the bottom of your css file.
HERE is another fiddle with media applied (just try to resize the box to see the effect)
I wonder if this is what you were looking for: jsfiddle
I changed your wrapper to this:
#wrapper {
position: fixed;
top: 50%;
left: 50%;
margin-top: -150px;
margin-left: -200px;
width:400px;
height:300px;
outline:1px solid red;
}
So that your div now sits in the middle of the screen
I have a variable width header that must have a background color that is as wide as the text (no wider). The only way I can think of doing this (with no extra markup) is to set the display to inline-block or float it to the left. The problem then though is that I cannot center the header (another requirement).
The closest I have got so far is by setting position: relative; on a floated header, pushing it across 50% from the left and then pulling it back 25% with negative margin, however this does not consistently center the header. It must remain in the flow of the document so position: absolute; is another no-go.
If you are aware of a way to do this using CSS only with no extra markup please let me know (pseudo-elements are fine, I'm not hassled about IE7 support)!
Solved using display: table; on the heading (with margin: 0 auto;).
you can give text-align:center; to the body as a global arrtibute & give display:inline-block to your header div. So,it's center your dynamic width in center like this :
CSS:
body{margin:0; padding:0;text-align:center}
p{text-align:left;}
.header{background:red;display:inline-block;}
Check this example http://jsfiddle.net/vpcXS/
replace the p tag with center as my markup is
<div id="header">
<center>hello</center>
</div>
and it's CSS is
body{
width:100%;
}
#header{
text-align:center;
}
#header center{
display:inline-block;
background:red;
}
We have a login page that is designed to have a 200px-high DIV vertically centered in the middle of the page. That is, it creates a 200 pixel blue band left edge to right edge (with form elements in it) that ideally should remain vertically centered in the viewport no matter how the browser window is resized.
This must be a CSS solution.
So let's say here's some sample markup:
<body>
<div id="mainDiv">
<div id="centerDiv" style="height:200px;background-color:blue;color:white">
Center this baby vertically in the #mainDiv, please!
</div>
</div>
</body>
Assume that my CSS dictates that the #mainDiv is stretched to cover the viewport top and bottom, which is easy enough to do. Are there CSS rules that I can apply to any of the elements or the page that will reliably and cross-browser (incl. IE6) vertically center #centerDiv? In a perfect world we should just be able to say
#centerDiv {
margin: auto 0;
}
And even in an OK world we should be able to address this issue with a few styles. But to quote Ving Rhames' character from Pulp Fiction, We're pretty %&#!ing far from OK.
I've looked at the solutions offered in Related Questions and scoured the Web. Nothing I can find really works 100%. Maybe this is unsolvable, but I thought I'd give the collective brains here the problem and see if I can get lucky. Thanks in advance.
If you have a fixed height, you can do it. Give the child div a top of 50% and a margin-top of -100px (or vice-versa) and you should be set.
if height unknown:
http://jsfiddle.net/Limitlessisa/a7xw6b2c/
.centerdiv{
background:red;
position:absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
For true automatic positioning in the center, the inner DIV would need to know the boundaries of the containing DIV. If your container does not have hard boundaries, there is no way for the inner DIV to calculate its own position automatically. It simply has no frame of reference.
The closest I think you can make it with a simple CSS solution is this:
#mainDiv
{
border: 1px dashed #000000;
}
#centerDiv
{
margin: 33% auto;
height: 200px;
}
