I'm trying to make a small username and password input box.
I would like to ask, how do you vertically align a div?
What I have is:
<div id="Login" class="BlackStrip floatright">
<div id="Username" class="floatleft">Username<br>Password</div>
<div id="Form" class="floatleft">
<form action="" method="post">
<input type="text" border="0"><br>
<input type="password" border="0">
</form>
</div>
</div>
How can I make the div with id Username and Form to vertically align itself to the center? I've tried to put:
vertical-align: middle;
in CSS for the div with id Login, but it doesn't seem to work. Any help would be appreciated.
I'm pretty late to the party, but I came up with this myself and it's one of my favorite quick hacks for vertical alignment. It's crazy simple, and easy to understand what's going on.
You use the :before
css attribute to insert a div into the beginning of the parent div, give it display:inline-block
and vertical-align:middle
and then give those same properties to the child div. Since vertical-align
is for alignment along a line, those inline divs will be considered a line.
Make the :before
div height:100%
, and the child div will automatically follow and align in the middle of a very tall "line."
.parent:before, .child {
display:inline-block;
vertical-align:middle;
}
.parent:before {
content:""; // so that it shows up
height:100%; // so it takes up the full height
}
Here's a fiddle to demonstrate what I'm talking about. The child div can be any height, and you never have to modify its margins/paddings.
And here's a more explanatory fiddle.
If you're not fond of :before
, you can always manually put in a div.
<div class="parent">
<div class="before"></div>
<div class="child">
content
</div>
</div>
And then just reassign .parent:before
to .parent .before
In my firefox and chrome work this:
CSS:
display: flex;
justify-content: center; // vertical align
align-items: center; // horizontal align
Unless the aligned div has fixed height, try using the following CSS to the aligned div:
{
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
display: table;
}
if you are using fix height div than you can use padding-top according your design need. or you can use top:50%. if we are using div than vertical align does not work so we use padding top or position according need.
This can be done with 3 lines of CSS and is compatible back to (and including) IE9:
.element {
position: relative;
top: 50%;
transform: translateY(-50%);
}
Example: http://jsfiddle.net/cas07zq8/
have you try this one?
.parentdiv {
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
height: 300px; // at least you have to specify height
}
hope this helps
Vertically aligning has always been tricky.
Here I have covered up some method of vertically aligning a div.
<div style="display:flex;">
<div class="container table">
<div class="tableCell">
<div class="content"><em>Table</em> method</div>
</div>
</div>
<div class="container flex">
<div class="content new"><em>Flex</em> method<br></div>
</div>
<div class="container relative">
<div class="content"><em>Position</em> method</div>
</div>
<div class="container margin">
<div class="content"><em>Margin</em> method</div>
</div>
</div>
em{font-style: normal;font-weight: bold;}
.container {
width:200px;height:200px;background:#ccc;
margin: 5px; text-align: center;
}
.content{
width:100px; height: 100px;background:#37a;margin:auto;color: #fff;
}
.table{display: table;}
.table > div{display: table-cell;height: 100%;width: 100%;vertical-align: middle;}
.flex{display: flex;}
.relative{position: relative;}
.relative > div {position: absolute;top: 0;left: 0;right: 0;bottom: 0;}
.margin > div {position:relative; margin-top: 50%;top: -50px;}
You can vertically align a div in another div. See this example on JSFiddle or consider the example below.
HTML
<div class="outerDiv">
<div class="innerDiv"> My Vertical Div </div>
</div>
CSS
.outerDiv {
display: inline-flex; // <-- This is responsible for vertical alignment
height: 400px;
background-color: red;
color: white;
}
.innerDiv {
margin: auto 5px; // <-- This is responsible for vertical alignment
background-color: green;
}
The .innerDiv
's margin must be in this format: margin: auto *px;
[Where, *
is your desired value.]
display: inline-flex
is supported in the latest (updated/current version) browsers with HTML5 support.
It may not work in Internet Explorer :P :)
Always try to define a height for any vertically aligned div (i.e. innerDiv) to counter compatibility issues.
I found this site useful: http://www.vanseodesign.com/css/vertical-centering/ This worked for me:
HTML
<div id="parent">
<div id="child">Content here</div>
</div>
CSS
#parent {
padding: 5% 0;
}
#child {
padding: 10% 0;
}
I needed to specify min-height
#login
display: flex
align-items: center
justify-content: center
min-height: 16em
If you know the height, you can use absolute positioning with a negative margin-top
like so:
#Login {
width:400px;
height:400px;
position:absolute;
top:50%;
left:50%;
margin-left:-200px; /* width / -2 */
margin-top:-200px; /* height / -2 */
}
Otherwise, there's no real way to vertically center a div with just CSS
I found a way that works great for me. The next script inserts an invisible image (same as bgcolor or a transparant gif) with height equal to half the size of the white-space on the screen. The effect is a perfect vertical-alignment.
Say you have a header div (height=100) and a footer div (height=50) and the content in the main div that you would like to align has a height of 300:
<script type="text/javascript" charset="utf-8">
var screen = window.innerHeight;
var content = 150 + 300;
var imgheight = ( screen - content) / 2 ;
document.write("<img src='empty.jpg' height='" + imgheight + "'>");
</script>
You place the script just before the content that you want to align!
In my case the content I liked to align was an image (width=95%) with an aspect ratio of 100:85 (width:height).Meaning the height of the image is 85% of it's width. And the Width being 95% of the screenwidth.
I therefore used:
var content = 150 + ( 0.85 * ( 0.95 * window.innerWidth ));
Combine this script with
<body onResize="window.location.href = window.location.href;">
and you have a smooth vertical alignment.
Hope this works for you too!
Centering the child elements in a div. It works for all screen sizes
#parent {
padding: 5% 0;
}
#child {
padding: 10% 0;
}
<div id="parent">
<div id="child">Content here</div>
</div>
for more details, you can visit to this link
simplest way to center your div element is to use this class with following properties.
.light {
margin: auto;
width: 50%;
border: 3px solid green;
padding: 10px;
}
divs can't be vertically aligned that way, you can however use margins or position:relative to modify its location.
@GáborNagy's comment on another post was the simplest solution I could find and worked like a charm for me, since he brought a jsfiddle I'm copying it here with a small addition:
CSS:
#wrapper {
display: table;
height: 150px;
width: 800px;
border: 1px solid red;
}
#cell {
display: table-cell;
vertical-align: middle;
}
HTML:
<div id="wrapper">
<div id="cell">
<div class="content">
Content goes here
</div>
</div>
</div>
If you wish to also align it horizontally you'd have to add another div "inner-cell" inside the "cell" div, and give it this style:
#inner-cell{
width: 250px;
display: block;
margin: 0 auto;
}
