I am going crazy, I'm trying to center some divs (relatively to the viewport).
The problem is that those divs that I want to center are nested in some rotated div (4deg).
.inner-wrap{
width: 200vw;
position: relative;
padding: 20vh 0;
right: -50vw;
left: -50vw;
bottom: -50px;
transform-origin: bottom left;
transform: rotate(-4deg);// HERE THE ROTATION
margin: auto;
}
I corrected the angle for the text in the article nested in the .inner-wraps
article{
transform: rotate(4deg);
max-width: 960px;
margin: auto;
}
THE PROBLEM:
The two rotations let the content slide a bit on the left resulting a bit annoying see the link :)

How can I fix this?
You can try giving a width to the titles, then position it relative to your window with 50% and margin-left: -(half of the width of the element) In this case I used -140px
section.who article.logo {
max-width: 280px;
position: relative;
left: 50%;
margin-left: -140px;
}
Ok, I'm an idiot! I setted the rotation origin as bottom left instead of center ....
This is the website I am modifying: sb460training.org
Here is the code snippet:
#apdiv1 {
position: absolute;
width: 2815px;
height: 276px;
z-index: 1;
top: 1px;
left: 0px;
background-color: #000;
}
#apdiv2 {
position: absolute;
width: 3150px;
height: 115px;
z-index: 2;
left: 0px;
top: 230px;
}
#apdiv3 {
position: absolute;
width: 221px;
height: 411px;
z-index: 3;
left: 0px;
top: 259px;
background-color: #FFF;
}
#apdiv4{
position: absolute;
width: 2853px;
height: 115px;
z-index: 4;
left: 219px;
top: 401px;
}
Do you know what the width dimensions should be so I can get rid of the annoyingly extra space that shows up to the right of the web page?
Thanks
Like the other answers, I agree that your CSS should change the fixed widths to 100%.
However, in your HTML you have img elements with explicit widths, to substitute background colours. For example, in the "apDiv2" DIV element, you have an in-line image containing white, "SB460_Pic/Secondary title2.jpg". This image is set to 2128px wide, causing the page to extend horizontally.
I would recommend removing the images that are being used to pad the right of each DIV, and instead set background colours in CSS.
UPDATE
Quick and dirty example:
http://pastebin.com/4PmZN1r4
change all your container widths to 100%.
give your html a width:100%; margin:0;
give your body a fixed width:1200px or so.
set your body with a margin: 0 auto if you want it centered.
I've heard the same similar issue.
all you need to do is try working with margin set to 0 and auto.
in most cases, try eliminating the use of 'position absolute' and work more with margin, padding and position relative.
I'm not finding any information on this. Might be because my approach is incorrect.
I'm having my image positioned absolutely under a div which uses full window width.
I'm using margin-left: 30%, so that images are always positioned 30% from the left border.
Everything else is set for responsive image handling..
I got the code correct that it scales like I want if the browser-window gets resized.
But because the image is not centered, the scaling happens "too late", so the right part will be hidden outside view.
Can I solve this with the scaling starting "earlier"?
Or using sth different than margin-left: 30% or left: 30% ?
see here: JsFiddle - Image out of view when resizing window
img.aaa
{
position: absolute;
max-width: 85%;
max-height: 85%;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin-top: auto;
margin-right: auto;
margin-bottom: auto;
margin-left: 30%;
}
You can use margin-left: auto which will center the image. If it has to be a certain distance from the left, use a container div and the following css. This will prevent the image from going outside the body and getting cut off.
.container {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
padding-left: 30%;
//text-align: center; //remove padding and uncomment this to center image in div
}
img.aaa {
max-width: 100%;
max-height: 85%;
box-shadow: 0 5px 10px rgba(0,0,0,0.8);
}

For past several hours I try to figure out why only one of absolute positioned divs with image backgroung appears. Here is my css code for absolute positioned div
.nastip {
position: absolute;
width: 64px;
height: 20px;
background-image: url(https://s3.amazonaws.com/assets.heroku.com/addons.heroku.com/catalogs/287/small.png);
right: -36px;
bottom: 2px;
}
Here is the whole code http://jsfiddle.net/6uAvq/
I need to display both images in absolute positioned divs.
I use chrome browser. Thank you for any advice.
You have a semicolumn in your css prior to .aakcia rule which terminates any more styles appearing after that.
; /*Remove this*/
.aakcia {
position: absolute;
width: 64px;
height: 20px;
background-image: url(https://s3.amazonaws.com/assets.heroku.com/addons.heroku.com/catalogs/287/small.png);
right: -36px;
bottom: 20px;
}
;

I would like to make a position: fixed; popup box centered to the screen with a dynamic width and height. I used margin: 5% auto; for this. Without position: fixed; it centers fine horizontally, but not vertically. After adding position: fixed;, it's even not centering horizontally.
Here's the complete set:
.jqbox_innerhtml {
position: fixed;
width: 500px;
height: 200px;
margin: 5% auto;
padding: 10px;
border: 5px solid #ccc;
background-color: #fff;
}
<div class="jqbox_innerhtml">
This should be inside a horizontally
and vertically centered box.
</div>
How do I center this box in screen with CSS?
If your div has a known width and height, then you basically need to set top and left to 50% to center the left-top corner of the div. You also need to set the margin-top and margin-left to the negative half of the div's height and width to shift the center towards the middle of the div.
position: fixed;
width: 500px;
height: 200px;
top: 50%;
left: 50%;
margin-top: -100px; /* Negative half of height. */
margin-left: -250px; /* Negative half of width. */
Or, if your div has a dynamic/undefined width and/or height, then instead of the margin, set the transform to the negative half of the div's relative width and height.
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
Or, if your div has at least a fixed width and you don't care about centering vertically and old browsers such as IE6/7, then you can instead also add left: 0 and right: 0 to the element having a margin-left and margin-right of auto, so that the fixed positioned element having a fixed width knows where its left and right offsets start. In your case thus:
position: fixed;
width: 500px;
margin: 5% auto; /* Will not center vertically and won't work in IE6/7. */
left: 0;
right: 0;
Again, this works only in IE8+ if you care about IE, and this centers only horizontally not vertically.
I want to make a popup box centered to the screen with dynamic width and height.
Here is a modern approach for horizontally centering an element with a dynamic width - it works in all modern browsers; support can be seen here.
Updated Example
.jqbox_innerhtml {
position: fixed;
left: 50%;
transform: translateX(-50%);
}
For both vertical and horizontal centering you could use the following:
Updated Example
.jqbox_innerhtml {
position: fixed;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
You may wish to add in more vendor prefixed properties too (see the examples).
Or just add left: 0 and right: 0 to your original CSS, which makes it behave similarly to a regular non-fixed element and the usual auto-margin technique works:
.jqbox_innerhtml
{
position: fixed;
width:500px;
height:200px;
background-color:#FFF;
padding:10px;
border:5px solid #CCC;
z-index:200;
margin: 5% auto;
left: 0;
right: 0;
}
Note you need to use a valid (X)HTML DOCTYPE for it to behave correctly in IE (which you should of course have anyway..!)
Add a container like:
div {
position: fixed;
bottom: 0;
left: 0;
width: 100%;
text-align: center;
}
Then put your box into this div will do the work.
Edit: as mentioned in the comments, the inner content needs to be set to display: inline-block assuming there're two divs like:
<div class="outer">
<div class="inner">
content goes here
</div>
</div>
Then the CSS for the inner needs to be:
.outer {
position: fixed;
text-align: center;
left: 0;
right: 0;
}
.inner {
display: inline-block;
}
Together with the outer div having a left: 0; right:0; and text-align: center this will align the inner div centered, without explicitly specifying the width of the inner div.
Just add:
left: calc(-50vw + 50%);
right: calc(-50vw + 50%);
margin-left: auto;
margin-right: auto;
Center fixed position element
(the simple & best way I know)
position:fixed;
top: 0; left: 0;
transform: translate(calc(50vw - 50%));
For centering it horizontally & vertically (if height is same as width)
position:fixed;
top: 0; left: 0;
transform: translate(calc(50vw - 50%), calc(50vh - 50%));
Both of these approaches will not limit centered element's width less than viewport width, when using margins in flexbox, inside centered element
#modal {
display: flex;
justify-content: space-around;
align-items: center;
position: fixed;
left: 0;
top: 0;
width: 100%;
height: 100%;
}
inside it can be any element with diffenet width, height or without.
all are centered.
This solution does not require of you to define a width and height to your popup div.
http://jsfiddle.net/4Ly4B/33/
And instead of calculating the size of the popup, and minus half to the top, javascript is resizeing the popupContainer to fill out the whole screen...
(100% height, does not work when useing display:table-cell; (wich is required to center something vertically))...
Anyway it works :)
left: 0;
right: 0;
Was not working under IE7.
Changed to
left:auto;
right:auto;
Started working but in the rest browsers it stop working!
So used this way for IE7 below
if ($.browser.msie && parseInt($.browser.version, 10) <= 7) {
strAlertWrapper.css({position:'fixed', bottom:'0', height:'auto', left:'auto', right:'auto'});
}
I used vw (viewport width) and vh (viewport height). viewport is your entire screen. 100vw is your screens total width and 100vh is total height.
.class_name{
width: 50vw;
height: 50vh;
border: 1px solid red;
position: fixed;
left: 25vw;top: 25vh;
}
You can basically wrap it into another div and set its position to fixed.
.bg {
position: fixed;
width: 100%;
}
.jqbox_innerhtml {
width: 500px;
height: 200px;
margin: 5% auto;
padding: 10px;
border: 5px solid #ccc;
background-color: #fff;
}
<div class="bg">
<div class="jqbox_innerhtml">
This should be inside a horizontally and vertically centered box.
</div>
</div>
I just use something like this:
.c-dialogbox {
--width: 56rem;
--height: 32rem;
position: fixed;
width: var(--width);
height: var(--height);
left: calc( ( 100% - var(--width) ) / 2 );
right: calc( ( 100% - var(--width) ) / 2 );
top: calc( ( 100% - var(--height) ) / 2 );
bottom: calc( ( 100% - var(--height) ) / 2 );
}
It centers the dialog box both horizontally and vertically for me, and I can use different width and height to fit different screen resolutions to make it responsive, with media queries.
Not an option if you still need to provide support for browsers where CSS custom properties or calc() are not supported (check on caniuse.)
This one worked the best for me:
display: flex;
justify-content: center;
align-items: center;
position: fixed;
left: 0;
top: 0;
width: 100%;
height: 100%;
To fix the position use this :
div {
position: fixed;
left: 68%;
transform: translateX(-8%);
}
simple, try this
position: fixed;
width: 500px;
height: 300px;
top: calc(50% - 150px);
left: calc(50% - 250px);
background-color: red;

According to the

6pt is about 8px
In the case of this demo the background

3 lines (with space between the lines)
times 80pt is about
~3*(1.3)*80pt*(8px/6pt)~ 416px
50% from the 416px = 208px

Try using this for horizontal elements that won't center correctly.
width: calc (width: 100% - width whatever else is off centering it)
For example if your side navigation bar is 200px:
width: calc(100% - 200px);
This works wonderfully when you don't know the size of the thing you are centering, and you want it centered in all screen sizes:
.modal {
position: fixed;
width: 90%;
height: 90%;
top: 5%; /* (100 - height) / 2 */
left: 5%; /* (100 - width) / 2 */
}
What I use is simple. For example I have a nav bar that is position : fixed so I adjust it to leave a small space to the edges like this.
nav {
right: 1%;
width: 98%;
position: fixed;
margin: auto;
padding: 0;
}
The idea is to take the remainder percentage of the width "in this case 2%" and use the half of it.
Had this problem so I concluded that using a (invisible) container is the best option (based on answer #Romulus Urakagi Ts'ai). To make it with flexbox:
.zoom-alert {
position: fixed;
justify-content: center;
display: flex;
bottom: 24px;
right: 0;
left: 0;
z-index: 100000;
width: 100%;
&__alert {
flex: 0 0 500px;
padding: 24px;
background-color: rgba(212, 193, 105, 0.9);
border: 1px solid rgb(80, 87, 23);
border-radius: 10px;
}
}
(the syntax is SCSS but can be easily modified to pure CSS)
Center element of a div with the property of
position:fixed
Html and Css code
.jqbox_innerhtml {
position: fixed;
width:100%;
height:100%;
display: flex;
justify-content: space-around;
align-items: center;
left: 0;
top: 0;
width: 100%;
height: 100%;
border: 5px solid #ccc;
background-color: #fff;
}
<div class="jqbox_innerhtml">
This should be inside a horizontally
and vertically centered box.
</div>
Another simple solution is to set the width of the element to fit-content and set the left and right to 0px;
width: fit-content;
position: fixed;
left: 0px;
right: 0px;
This is useful if you don't know the width of the element.
The only foolproof solution is to use table align=center as in:
<table align=center><tr><td>
<div>
...
</div>
</td></tr></table>
I cannot believe people all over the world wasting these copious amount to silly time to solve such a fundamental problem as centering a div. css solution does not work for all browsers, jquery solution is a software computational solution and is not an option for other reasons.
I have wasted too much time repeatedly to avoid using table, but experience tell me to stop fighting it. Use table for centering div. Works all the time in all browsers! Never worry any more.
