thiv.net/mobile needs to work on mobile, and it does, however when I turn my ipod to vertical, it changes drastically, my problem is i need the whole lot, textbox, button and image to be centered vertically, or change on rotate. I think centering the div vertically is the best option, so what css would i use?
Currently i have tried:
.center
{
position:absolute
top:40%;
bottom:40%;
height:20%;
}
But that doesn't work, so maybe it should only be centered after rotating?
Any ideas?
Try following CSS :
.center {
width: 100px;
height: 100px;
position: absolute;
top:0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}
you can also follow the link of stack-overflow : Best way to center a <div> on a page vertically and horizontally?
If you know the height:
div.centered{
height: 100px;
top: 50%;
margin-top: -50px;
}
Optional: position: absolute | relative | fixed depending on what you want to achieve
the margin-top should always be 0 - half of the height of your div to center.

For the life of me I can't figure out why nothing will centre.
This image explains better than I could about what I want.
I want to centre all fields without changing which way around the kanji appear (For some reason the {{Expression}} field keeps flipping when I try to centre.
http://pastebin.com/PqEN9xMT
In your Templates wrap the Expression field with a div, give the div a class, and then center it with css styling.
If you want the absolute center of the main window try:
Front Template:
<div class='center-me'>
{Front}
</div>
Styling:
.center-me {
width: 100px;
height: 100px;
position: absolute;
top:0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}
I have a div which has its CSS initially defined as:
.mydiv {
position: absolute;
top: 60px;
left: 60px;
right: 60px;
bottom: 60px;
background-color: cyan;
overflow: hidden;
}
That is with equal distance from screen borders and I wanted to make it draggable via jQuery. This wouldn't work because of the right and bottom CSS directives.
So my next idea was to use this CSS definition:
.mydiv {
position: absolute;
width: 90%;
height: 90%;
margin-left: 5%;
margin-top: 5%;
background-color: cyan;
overflow: hidden;
}
Which according to my understanding would create a div with a width and height equal to 90% of the screen width/height and additionally the margin directives (5% on each side) would position it in the center of the screen.
This solution doesn't seem to work for 100%.
It works horizontally, the div is centered horizontally BUT vertically the space in the bottom is less than the space on top. Which is not what I want it to be.
I know I could use calc() to solve it in a different way but I want to avoid it due to browser compatibility (IE8).
I was wondering what I'm doing wrong?
i'm kind of stupid today.
i removed the margins and used:
top: 5%;
left: 5%;
and it solved my problem.
I'm looking to center text both vertically and horizontally over an image that grows when the page gets wider.
I originally had the image set as the background for a div of fixed height, in which case it was relatively easy to center it, but because background images aren't structural, I couldn't set the height to be an automatic function of the width, and I had to toss this option out when I went for a more responsive design.
So I've currently got a div with two elements in it, img and overlay text. The image width is set to 100% of the width of its container, and the height varies accordingly. As a consequence, though, I can't set the overlay text to be postion:absolute and top:80px or something, because the distance from the top will have to vary. And even doing top:25% or whatever doesn't work, because a) if that page width shrinks to squeeze the text, or if there's just more text, the vertical centering is thrown off when there are more/less lines, and b) the percentage is arbitrary -- it's not 50 or something, because that would put the top of the text overlay 50% down the image, when I want the center of the overlay to be there.
I've looked, among other things, at this post, which is definitely close -- but in both solutions, the image height is incapable of resizing, and in the former, the JS loads at page load, but then freezes, so that if I change page width/height, things get out of whack. Ideally, this solution wouldn't involve JS for just that reason (even if it reloaded on every resize, that feels non-ideal), but if that's the only solution, I'll take it.
Also, just for added details/fun, I've set a max-height on the image, because I don't want it to exceed roughly 300px height, even on a cinema display.
Basic fiddle of current attempt here, and identical code below. Any ideas? Thanks!
html
<div class='quotation_div'>
<img src='http://www.mountainprofessor.com/images/mount-ranier-mount-features-2.jpg'>
<div class='overlay'>
<p>Any reasonable amount of text should be able to go here. I want it to be able to center vertically even if it takes up 2 or 3 lines.</p>
</div>
</div>
css
.quotation_div {
position: relative;
display: table;
}
img {
width: 100%;
max-height: 300px;
}
.overlay {
z-index: 99;
width: 70%;
margin-left: 15%;
vertical-align: middle;
position: absolute;
top: 25%; /* Obvious problem, cause it's arbitrary */
}
p {
text-align: center;
color: red;
font-size: 165%;
font-weight: lighter;
line-height: 2;
}
You can use CSS background-size to set the width to 100% and the height will be calculated to maintain aspect ratio.
Here's a fiddle using that technique.
If you want the image as an HTML element then I suggest you set it's position to absolute and use the same method of disply:table-cell to center the overlay:
Here's a fiddle using that method, this one stretches the image because of the max-height.
Please Try the below css for .overlay as in your fiddle
.overlay {
z-index: 99;
width: 70%;
/* height: 100%; */
/* margin-left: 15%; */
/* vertical-align: middle; */
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}
or this is the updated fiddle link http://jsfiddle.net/hLdbZ/284/
I use this combination:
.CONTAINER {
position: relative;
text-align: center;
}
.TEXT {
text-align: center;
position: absolute;
top: 50%;
left: 0;
right: 0;
}
.IMG {
//for responsive image
width: 100%;
height: auto;
}
I just added to the html
<div align="center"></div>
to surround your existing code to get the image to center
hope that helps
I'm currently changing a PSD design to a HTML site. I've come into an issue however. I am unable to center a certain element. I've tried all the usual tricks.
http://lowhop.net/
See here the main blue header is out of line (not centered). I tried
#slider{
position:absolute;
left:0;
right:0;
margin-left:auto;
margin-right:auto;
Before, however it didn't work reliably. (Appeared only to work on my screen resolution/browser).
Thanks
You need to explicitly define a width on the element when using margin: 0 auto to center.
Block elements take up the full available viewport width unless you explicitly give them a width.
Since you explicitly set the width of the slider DIV, you can use another trick to center it:
#slider
{
z-index: 2;
background-image: url(../img/sliderbg_09_09.png);
position: absolute;
display: block;
width: 982px;
height: 251px;
left: 50%;
margin-left: -491px; /** half DIV width */
}
I'd probably steer away from having this as a position absolute DIV, doesn't look like it needs it but that's a quick and dirty centering :)
Hope that helps
If you must use absolute positioning, you can use something like my answer here.
Basically, you declare an explicit width for your element, then give it
left: 50%;
margin-left: -[your width/2];
like user showdev mentioned :
Does it need to be positioned absolutely? Does it even need to be centered? It looks like you've positioned div#navBar simply by adding margin-left: 85px. It seems that you could use that same method for div#slider.
you have
#navBar {
background-image: url("../img/navbg_07.png");
display: block;
height: 38px;
margin-left: 85px; /* attention on this */
margin-top: 31px;
position: relative;
width: 879px;
z-index: 1;
}
and this
#slider {
background-image: url("../img/sliderbg_09_09.png");
display: block;
height: 251px;
position: absolute;
width: 982px;
z-index: 2;
}
so, try 'margin-left: 85px;' your #slider.
I have a form I would like to center directly in the middle of a page. I have this CSS
#form {
width: 240px;
height: 100px
margin: 0 auto;
display: block;
}
this only does it horizontally. Is there a way to do it vertically?
I might be wrong but if I remember correctly.. this should work:
#form {
width: 240px;
height: 100px
position: absolute; /* make sure this is wrapped by an element with "position: relative" */
top: 50%;
left: 50%;
margin: -50px 0 0 -120px; /* half of the height and width */
}
If I'm wrong, then you probably have to use javascript.
Not really - you can declare an offset from the top of the page, but think about it for a moment...how tall is a webpage? What does it mean to be centered vertically?
Do you want to be centered relative to the open browser window height? Or centered relative to the height of the page (top of header to bottom of footer, regardless of browser window size).
On preview, the comments on the original post cover this well.
