I’ve got an online photo gallery. The thumbnail page is a grid of 150px x 150px divs, the thumbnail images are set inside them.
Since the thumbnail images are rectangular, the ideal thing would be to auto-center them inside the divs.
Reading here, I’ve figured out how to center them horizontally. I’ve also been reading that auto-centering vertically isn’t possible until CSS3 takes off. Is this true?
I've gotten the horizontal images to auto center with this:
.portrait_t {
width: auto;
height: 150px;
text-align: center;
display: block;
margin: 0 auto 0 auto;
}
But, the vertical centering doesn't work with this:
.landscape_t {
width: 150px;
height: auto;
display: block;
margin: auto 0 auto 0;
}
If there's just no way to do this until CSS3 then I'll have to come up with a workaround, but if I'm missing something, please let me know.
Thank you all in advance for your help!
You have an inline element (the <img>) that is inside a sized parent <div> element:
<div>
<img />
</div>
All you need to do is to make it center and middle aligned. You center it with text-align:center; in the parent <div> and you middle align it by giving the <div> the line-height of it's full height. Additionally, as it's an <img> tag you give that image tag the vertical-align:middle; that done it's in there, regardless of it's own size:
Example/Demo:
<style>
div {width:350px; height:350px; line-height:350px; text-align:center;}
div img {vertical-align:middle;}
</style>
<div>

This is my first post, so please be gentle. I've searched thoroughly for an answer but had no luck - I'm sure it must be something simple but I'm running out of ideas...anyway:
I'm making a responsive site but there's an image that I want to keep at a fixed size. It took me ages to work out how to do this (by removing "max-width: 100%"), however this has had the bizarre effect of changing its alignment so it is no longer centred on the page.
How can I have both? Centred and a fixed size?
Any help much appreciated.
Oh and this is what my image css is looking like at the moment:
img {
height: auto;
min-width: 100%;
display: inline-block;
margin-left: auto;
margin-right: auto;
}
Thanks for all your help so far - although this is still far from resolved I'm afraid. Figured I'd show my code in full as some of you have suggested, so I put it into jsfiddle. However it works absolutely fine there - the window can be resized with the image still retaining it's full dimensions and still remaining in the centre of the page. Yet with exactly the same code, when I load the 'index' page from my PC into Chrome, the image at the bottom either retains its size but drifts to the right when the window is shrunk, or it stays in the centre but shrinks to a ridiculous size. Any idea why there might be such a discrepancy?
Here's my jsfiddle anyway, which might have some clues:

Thanks again.
If I understand you right, you want to add an image which should still be centered even if the parent element's width is smaller than the image. This could be done by using an image wrapper div which is pretty wide and position it accordingly. Also, the image itself should be centered in that wrapper.
In the following example, the layout has two columns, each with an image of 300x300px. If you resize the viewport (use the "Full page" view mode), the images will still be centered (see how the "x" in the placeholder images stays visible).
html, body, .column {
padding: 0;
margin: 0;
}
.column {
display: block;
float: left;
width: 50vw;
height: 100vh;
background-color: #ccf;
overflow: hidden;
}
.column + .column {
background-color: #ffc;
float: right;
}
.img-wrapper {
width: 10000px;
margin-left: calc(-5000px + 50%);
text-align: center;
}
.img-wrapper img {
margin: 0 auto;
}
<div class="column">
Column 1
<div class="img-wrapper">
<img src="http://placehold.it/300x300" />
</div>
</div>
<div class="column">
Column 2
<div class="img-wrapper">
<img src="http://placehold.it/300x300" />
</div>
</div>
Can be done by wrapping the image in a <div> like so:
HTML:
<div>
<img src="..." alt="random blue sky image" />
</div>
CSS:
div {
width: 100%;
text-align: center;
}
img {
width: 250px; /* or whatever width you need the image to be */
}
Here's a demo of the code.
If that didn't help, we'll ask that you present us with the problematic code. Jsfiddle.net is an easy way to do that.
I am trying to create something like a gallery that shows different number of images per row based on the width of the browser. This has already been achieved using overflow: hidden in the outer div and float: left in the inner div.
However, what happens with this is that my images are always aligned to the left, leaving alot of whitespace on the right. How do I make it such that the gallery is always centered in the screen no matter how many images there are per row.
My code is on http://codepen.io/anon/pen/KzqAs
Thank you very much. :)
How about this: http://codepen.io/anon/full/mtBbF
HTML
<div class="container">
<div class="red box">red</div>
<div class="blue box">blue</div>
<div class="black box">black</div>
</div>
CSS
body{
text-align:center; /*You would need to define this in a parent of .container*/
}
.container{
display: inline-block;
margin: 0 auto;
text-align: left;
}
.box {
width: 300px;
height: 300px;
float: left;
}
Demonstration
You need to use an id(or class) on the main div. Set width: 300+px and margin: auto
Also your boxes should be with display: inline-block to allow them to begave "inline"
I have changed colors of the boxes a bit for better visibility.
This is my relevant page markup:
<div id="header">
<div id="logo">
Home
</div>
<div id="user_box">
test
</div>
</div>
And my relevant CSS:
#header {
width: 960px;
height: 110px;
}
#logo {
background: url('/assets/img/logo.png') no-repeat center;
width: 300px;
height: 110px;
float: left;
}
#user_box {
width: 300px;
height: 60px;
float: right;
vertical-align: middle;
}
Now, I want to position the user_box div in the vertical middle of the header div. After a lot of Google'ing and experimenting, I have learned that this isn't easy. Apparently, I can't vertical align a block element such as a div. So I'm looking for a different way to do this.
I saw the hacky display: table; method and tried using it, but it didn't change a thing. Also tried changing the element to an inline element like a span, but that didn't work either. I even tried using margin: auto 0; for some god awful reason, and that also didn't work at all.
So I'm asking for help. How do I vertically align this div inside my header div?
Thanks!
Set the line-height of user_box equal to the height of header
Working demo: http://jsfiddle.net/AlienWebguy/pyppD/
vertical align doesn't work with divs its for aligning elements in tables. In your case you could just use this
#user_box { margin-top:25px; } /*110-60 = 50/2 = 25*/
So I fiddled around with your code a little bit, and here's what I got: http://jsfiddle.net/3k8XE/
As you can see I'm using a table as the header, and applying the same id to each element, except the two inner divs have changed to td's. I've added an inner td to compensate the space between the two divs since they were originally set to float:left/right.
(Of course the borders are just to show what's actually going on here.)

At the standard zoom level the entire blog is aligned left and there is this huge no mans land to the right. How can I cut the size of the page down so the blog is centered at all zoom levels?
Ive tried some simple css and cant seem to figure it out.
Thanks!
Hmm. How about putting your main content in a div and centering that with:
margin: 0 auto;
width: /* the width of your content */
You'd have to rearrange your html markup though; I tried doing this, but it cut off your background. You'll have to take your background-image out of the div you want to center and put it around that div. If that makes sense.. Something like:
<body>
<div id="bg"><!-- give this id the background-image in css -->
<div id="maincontent">
<!-- this div contains all your content, everything that needs centering -->
</div>
</div
</body>
Then in your css:
#bg { background-image: /* blabla */ }
#maincontent { margin: 0 auto; width: /* width, as stated above */ }
Something like that.
Is this what you're looking for:
.main-width { margin: 0px auto; }
give the wrapping div a fixed width and give it a margin: 0 auto
My problem is best outlined with this schematic/image which outlines how I want it to look:
!
I have a background image and 2 divs for text over the top of it (headline, and intro-text). I also have 2 divs on either side of the headline - these are for the white horizontal stripes.
My issue is that the headline is changeable in a CMS, and I want the horizontal white stripes to automatically fill up the space to the left and to the right of it, regardless of the headline's width.
I can't figure out how to make those 2 horizontal white stripes resize automatically.
Here's my HTML:
<div id="masthead">
<div id="headline-container">
<div id="left-stripe"> </div><div id="headline">{headline}</div><div id="right-stripe"> </div>
</div>
<div class="clear-both"> </div>
<div id="intro-text">{intro_text}</div>
</div>
And here's my CSS - ignore the widths specified for the left-stripe and right-stripe - they're just placeholders:
#masthead {
height: 260px;
}
div#headline-container {
width:960px;
padding:none;
}
div#left-stripe{
float: left;
background-color:#fff;
height: 3px;
width:500px;
display: inline;
}
div#right-stripe{
float: right;
background-color:#fff;
height: 3px;
width:100px;
display: inline;
}
div#headline {
text-align:right;
color: #fff;
font-size: 200%;
float: left;
display: inline;
}
div#intro-text {
text-align: left;
float: right;
width: 300px;
color: #fff;
}
Ideas? Please let me know if I can provide more detail.
I'm a bit too busy to actually test this, but this might give you some direction. i'm not sure the exact effect you're trying to achieve (see comment about finding a live demo someone made).
Regardless, this kind of fluid layout is a bit difficult to achieve reliably with straight CSS. To make it easier I would suggest making the right-stripe a static width.
This CSS solution MIGHT work... no promises.
markup
<div class="container">
<div class="headline-container">
<div class="left-stripe"></div>
<div class="headline">Headline goes here</div>
<div class="right-stripe></div>
</div>
<div class="content"></div>
</div>
CSS
//static width for right stripe
.right-stripe { width: 20px; }
.headline { width: auto; }
.left-stripe { width: auto; }
Using javascript would make it really easy though... here's how i would do it with jQuery. Again, I would make the right-stripe a static width to achieve this effect.
(same markup...)
..
js
var totalWidth = $("#container").width();
var leftWidth = totalWidth - ($("headline").width() + $("right-stripe").width());
$("left-stripe").width(leftWidth);
You can do this dynamically, with jQuery, for example. You take the full width of the 3 div's, drop the size of the inner div and assign dynamically the widths of the 2 outer div's in which the bar should repeat horizontally.
Basically, you will need:
$("#whole-div").width() - $("#inner-div").width() for the outer div's total width. Then, depending on your positioning of the inner-div, you assign values for the outer div's.
For example: whole div has 1000px, inner div has 200px and inner div is positioned 600px left. You will then assign 600px to the left div ($("#whole-div").width() - $("#inner-div").css('left')) and 200px for the right div ($("#whole-div").width() - $("#inner-div").css('left') - $("#inner-div").width()). Of course, you will then set a background-repeat property on the outer div so that the image repeats.
Hope that helps!
UPDATE CSS only fluid solution: http://jsfiddle.net/SebastianPataneMasuelli/XnvYw/1/
it uses the same background image twice, on #masthead and on #headline-container. except ton headline container the background is offset to match its left position relative to its parent element. then we only need one div.line behind it, which gets covered by the background image under the headline and copy, giving the illusion of a seamless image.
do you mean like this?: http://jsfiddle.net/SebastianPataneMasuelli/XnvYw/
