vertical centering using "table-cell" within bootstrap - html

I want to vertically and horizontally center a div using the "table-cell" method because is not requiring a specific height, but unfortunately is not working without specifying a height.
Why is not working ?
I have this markup:
<section class="content-01 v-center">
<div>
<div class="container">
<div class="slogan text-center">
<h1>VERTICAL CENTERING</h1>
</div>
</div>
</div>
and this css:
.content-01.v-center {
display: table;
width: 100%;
}
.content-01.v-center>div {
display: table-cell;
vertical-align: middle;
margin-top: 0;
margin-bottom: 0;
float: none;
}
And here is a jsfiddle
Any ideas what am I doing wrong ?
Thanks!

The problem here is that the html and body tags end before the bottom of the viewport:
At the very least you would have to tell the browser that the height of the html and body elements is at least 100%:
html, body {
height: 100%;
}
As well as specifying a height for the container section:
.content-01.v-center {
/* ... */
height: 100%;
}
Here's an updated fiddle: http://jsfiddle.net/2ntK2/3/

HTML produces white space

I am developing a page with Angular 2 and PrimeNG Design Framework. While creating a simple layout consisting out of a menu bar and a content part which should be placed below the menu and fill the whole remaining space. But anyhow there is a gap at the bottom as you can see on the picture and I can't explain myself why.
And this is my HTML- Code
#siteContainer {
height: 100%;
width: 100%;
display: table-row;
}
#menuContainer {
display: table-row;
}
#p-tabView {
height: 100%;
}
<div id="siteWrapper" style="min-height: 100%; width: 100%; display: table">
<!-- Top Menu Bar -->
<div id="menuContainer">
<app-skeleton></app-skeleton>
</div>
<!--Container for site content-->
<div id="siteContainer">
<p-tabView id="tabView" orientation="bottom">
<div id="tabPanelContainer">
<p-tabPanel>
<!--tabbody-->
<p-card>
<app-display-widgets style="{border: #7A7A7A 2em solid;}" *ngIf="sheet.id === refreshCurrentSheet()" [dashboardID]="dashboard.id"></app-display-widgets>
</p-card>
</p-tabPanel>
</div>
</p-tabView>
</div>
</div>
Add margin:0 to your html and body tag
<style>
html, body{
margin: 0;
}
#siteContainer {
height: 100%;
width: 100%;
display: table-row;
background: blue;
}
#menuContainer{
display: table-row;
}
#p-tabView {
height: 100%;
}
add this to your code see if that will fix the problem
body {
margin:0;
padding:0;
}
Check if your router outlet is maybe wrapped inside container fluid, and if so either change container's fluid css to your liking or remove the wrapping div/container

CSS Image pos middle in dynamic proportionally height/width div

Need to solve this little task:
Center vertically and horizontally IMAGE in DIV.
DIV height must be proportional to width.
DIV width is stretchable (for example 50% of parent div).
IMAGE width and height = auto (it must fill div if its width or height > than div width or height, and have primary size if its < div size, and stay proportional).
I know how to make 2 and 3.
HTML:
<div class="container">
<img src="img.png"/>
</div>
CSS:
.container {
width: 100%;
height: 0;
padding-bottom: 100%;
}
But how to center and middle IMAGE in this DIV?
There is a lot of ways to make 1 task with non proportional and non strechable div.
But I dont know how to make it all in full house of tasks.
Can you help? HTML and CSS may be any.
Did you try :
.container img {
vertical-align : middle
}
? It will verticaly align your image.
Try this:
<style>
.container
{
width :100%;
height :100%;
display :table;
}
.child
{
vertical-align :middle;
display :table-cell;
}
.child img
{
display :block;
width :50%;
margin :0 auto;
}
</style>
<div class="container">
<div class="child">
<img src="img.png"/>
</div>
</div>
Solved it by myself. Check here: http://jsfiddle.net/42trk8ux/17/

<div class="block">

Vertically aligning h1 and keeping width at 100%

I have the following HTML:
<div class="section-cover dark-cyan" ng-style="{height: getCoverHeight()}">
<div class="container">
<h1 class="intro">Some intro text.</h1>
</div>
<div class="arrow-holder" ng-click="scrollTo('video-container');">
<span class="arrow"></span>
</div>
</div>
The .section-cover div changes height dynamically based on viewport size whenever the browser is resized. I need to align the <h1> element vertically inside the section-cover div. So far I've achieved that using display: table-cell however now I can't get the width to stick at 100%. Here's a JSFiddle example:
http://jsfiddle.net/AvrrM/
How can I modify this to vertically align the <h1> and keep the width at 100%?
Maybe something like this?
http://jsfiddle.net/AvrrM/1/
.section-cover {
position: relative;
display: table;
vertical-align: middle;
width: 100%;
}
.container{
display: table-cell;
background: red;
text-align: center;
vertical-align: middle;
}
Why is itsn't working?? because table-cell is similar to html table, you need to provide a container which is table type before you can make the table-cell occupy the full width!!
working fiddle
add this CSS in your markup :
html, body {
width: 100%;
height:100%;
margin:0;
padding:0;
}
#table {
width: 100%;
display:table;
text-align:center;
}
HTML
<div id="table">
<div class="section-cover dark-cyan" style="background: blue; color: white; height: 200px">
<!-- all inner html here -->
</div>
</div>

Set div to remaining height using CSS with unknown height divs above and below

Is it possible to make the wrapper fill the window height (no scrolling) and the center div scrollable without messing around with pixels and javascript?
<div id="wrapper">
<h1>Header</h1>
<div id="center">
<div style="height:1000px">high content</div>
</div>
<div id="footer">Footer</div>
</div>
Basically I want the header to be visible at the top and the footer to be always visible at the bottom and have a scrollable content in the center which occupies the remaning height.
The header, footer and center divs' heights are all unknown (no set px or %, i.e. variable font-size or padding). Is it possible with pure CSS?
2014 UPDATE: The modern way to solve this layout problem is to use the flexbox CSS model. It's supported by all major browsers and IE11+.
2012: The correct way to do this with CSS alone is to use display: table and display: table-row. These are supported by all major browsers, starting with IE8. This is not using tables for display. You'll use divs:
html, body {
height: 100%;
margin: 0;
}
.wrapper {
display: table;
height: 100%;
width: 100%;
background: yellow; /* just to make sure nothing bleeds */
}
.header {
display: table-row;
background: gray;
}
.content {
display: table-row; /* height is dynamic, and will expand... */
height: 100%; /* ...as content is added (won't scroll) */
background: turquoise;
}
.footer {
display: table-row;
background: lightgray;
}
<div class="wrapper">
<div class="header">
<h1>Header</h1>
<p>Header of variable height</p>
</div>
<div class="content">
<h2>Content that expands in height dynamically to adjust for new content</h2>
Content height will initially be the remaining
height in its container (<code>.wrapper</code>).
<!-- p style="font-size: 4000%">Tall content</p -->
</div>
<div class="footer">
<h3>Sticky footer</h3>
<p>Footer of variable height</p>
</div>
</div>
That's it. The divs are wrapped as you'd expect.

Using overflow:auto will let you do this.
demo
So what you are talking about is a sticky footer. I went and did some more research and here is what I have for you.
<div id="wrapper" style="height:100%">
<div id="header" style="float:none;"><h1>Header</h1></div>
<div style="overflow:scroll;float:none;height:auto;">high content</div>
<div id="footer" style="clear:both;position:fixed;bottom:0px;"><h1>Footer</h1></div>
</div>
This will give you a sticky footer. The key is position:fixed and bottom:0px;
Unfortunately this means it also hovers above any content in the scrollview. So far there seems to be only Javascript to figure this out but I will keep looking.

CSS Using div to simulate tables

I'm new as webdesigner and I have to create a portion of a page that has 3 columns: a menu on the left side, the central body and a vertical banner. I can't use tables, so I've created a similar HTML:
<div class="Body">
<div class="LeftMenu">My menu</div>
<div class="Content">Foo body</div>
<div class="VerticalBanner">My menu</div>
</div>
While the CSS:
.LeftMenu {
width: 20%;
}
.Content {
margin: auto;
left: 20%;
position: absolute;
top: 0px;
width: 60%;
}
.VerticalBanner {
left: 80%;
margin: auto;
position: absolute;
top: 0%;
width: 20%;
}
So, my problem using that code is that the parent div (Body) takes the height of the first div (LeftMenu), which is not the bigger. This causes the content of "Content" and "VerticalBanner" to flow out "Body" and to go under the Footer div. If I use the float attribute, the "Body" div collapse without dimensions and then the footer div slides under the three columns inside "Body".
I also tried with display attribute, but Internet Explorer doesn't support this and some columns have strange behaviour.
What is the correct way to do this?
I think you should use floats for your DIVs. It's much easier after that to move them around.
Use display: table-*:
.Body { display: table; }
.Left, .Content, .VerticalBanner { display: table-cell; }
See e.g. this JSfiddle.
To stop the body div from collapsing you can use
.body{ overflow: hidden; }
I'm don't think you need position absolute.
<div class="Body">
<div style="width:20%;float:left;">My menu</div>
<div style="width:60%;float:left;">Foo body</div>
<div style="width:20%;float:left;">My menu</div>
<div style="height:1px;font-size:1px;clear:both;"> </div>
</div>
