Centering wide div inside a thinner mask div - css

I'm trying to center a wide div inside a smaller one, and center it. Can this be done?
I've got this:
HTML
<body>
<div id="full_container">
<div id="machine_mask">
<div id="machine_container">
<!---- SOME CONTENT HERE --->
</div>
</div>
<div class="machine_footer">
<img src="sprites/base_maquina.png" alt="panel de control" />
</div>
</div>
</body>
CSS
body {
margin :0;
}
div#full_container {
width: 100%;
height: 100%;
background: #805080;
}
div#machine_mask {
margin-top: 30px;
width: 100%;
display: inline-block;
height: 600px;
background: #805080;
position: relative;
overflow: hidden;
}
div#machine_container {
width: 1230px;
height: 500px;
background: #805080;
position: relative;
margin-left: auto;
margin-right: auto;
overflow: hidden;
}
When the window is wider than 1230px, it centers, but I really need for it to be centered when the window is smaller...
Is there a way to do this? (I was thinking about using jQuery and repositioning it, but I'd really prefer to do this in css)
Thank you very much!

You could use the absolute positioning hack.
div#machine_container {
width: 1230px;
height: 500px;
background: #805080;
position: absolute;
left: 50%;
margin-left: -615px; //half of 1230px
overflow: hidden;
}

Image is larger than overlay element by 1px

I am trying to overlay an image using a pseudo-element that is aligned to the bottom of a parent element. Then parent then hides part of both the image and the pseudo element using overflow: hidden. This should make the parent clip both the image and the pseudo element at the same place. However the image extends beyond the pseudo element by 1px. This happens in both Chrome and IE at specific breakpoints.
I inserted the code to stackoverflow but I can not reproduce using their code viewer. I can however reproduce on codepen using a screen width of 800px:
https://codepen.io/dwigt/pen/PXyrXq
.wrapper {
margin: auto;
}
.item {
background: lightgrey;
max-height: 500px;
min-height: 500px;
height: 100%;
max-width: 800px;
}
.image {
overflow: hidden;
max-height: 250px;
position: relative;
}
.image img {
max-height: 100%;
width: 100%;
position: relative;
}
.image::after {
z-index: 10;
content: "";
position: absolute;
left: -50%;
top: calc(80%);
width: 200%;
height: 200%;
display: block;
background: lightgrey;
border-radius: 100%;
}
<div class="wrapper">

Can't define relative vertical position of div within nested structure

I'm using Swipe.js to create a page with several screens. Swipe requires a structure of 3 nested divs, with some style defined. I want to position an element 70% towards the bottom of one of the screens, but I'm finding that its Y position remains at the top when defined as a percentage. My guess is that the height of the containing div is somehow still 0, though I have set all min-height properties to 100%.
I'm testing on Chrome in desktop, for now. My stylesheet:
/* required by swipe.js */
.swipe {
overflow: hidden;
position: relative;
min-height: 100%; /* added this everywhere I could just in case */
}
.swipe-wrap {
overflow: hidden;
position: relative;
min-height: 100%;
}
.swipe-wrap > div {
float: left;
width: 100%;
min-height: 100%;
position: relative;
}
.page {
min-height: 100%;
}
html,body {
height: 100%;
margin: 0px;
padding: 0px;
}
/* element I want to position */
.myElement {
position: relative;
width: 200px;
top: 70%;
left: 50%;
transform: translate(-50%, -50%);
}
Body:
<div id="slider" class="swipe">
<div class="swipe-wrap">
<div class="page">
<div class="myElement">
<h1>I should be more than halfway down.</h1>
</div>
</div>
</div>
</div>
The result is that the inner div is centred horizontally, but vertically it's at the top (in fact, cut off because of the transform offset).
I have tried using flex and align-items: center. That does work. I'm not sure if I can use flex to define arbitrary relative positions, though.
Please check below example
.swipe {
overflow: hidden;
position: relative;
height: 100%;
}
.swipe-wrap {
overflow: hidden;
position: relative;
height: 100%;
}
.swipe-wrap > .page {
display: table;
width: 100%;
height: 100%;
table-layout: fixed;
text-align: center;
}
.myElement{
display: table-cell;
vertical-align: middle;
}
.page {
min-height: 100%;
}
html,body {
height: 100%;
margin: 0px;
padding: 0px;
}
<div id="slider" class="swipe">
<div class="swipe-wrap">
<div class="page">
<div class="myElement">
<h1>I should be more than halfway down.</h1>
</div>
</div>

css - footer wont stick at the bottom

Im building a website and the footer wont stick at the bottom. Could someone help me with this issue?
CSS
#footer {
background-color: #454245;
bottom: 0;
float: right;
height: 200px;
left: 0;
margin-top: auto;
overflow: hidden;
position: relative;
width: 100%;
}
Try like this: LINK
HTML:
<div class="wrapper">
<p>Your content goes here.</p>
<div class="push"></div>
</div>
<div class="footer">
<p>Footer content</p>
</div>
CSS:
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -155px; /* the bottom margin is the negative value of the footer's height */
}
.footer,.push{
background-color:#ccc;
height: 155px;
}
You will have to provide position as absolute and it will only work when you can provide a wrapper or a parent div with position relative.
Look at this fiddle [http://jsfiddle.net/tLyC6/]1
You can have a sticky footer by setting its position: fixed (not relative) with bottom: 0
#footer {
background-color: #454245;
bottom: 0;
height: 200px;
overflow: hidden;
position: fixed;
width: 100%;
}
If you want footer to stick at the bottom, you can do it with using less code.
#footer {
background-color: #454245;
height: 200px;
margin:0 auto;
width: 100%;
}

Automatically inherit height of div for top attribute of another div?

Here's my working example:
http://jsfiddle.net/UGhKe/2/
CSS
#body {
height: 200px;
background: black;
width: 100%;
}
.header {
position: fixed;
top: 0;
background: #369;
z-index: 1;
width: 100%;
height: 5em;
}
.content {
position: absolute;
top: 5em;
overflow: hidden;
height: 1000px;
background: #936;
z-index: 0;
width: 100%;
}
.footer {
position: fixed;
bottom: 0;
background: #396;
width: 100%;
}
.large {
font-size: 120%;
padding: 2em;
}
HTML
<div id="body">
<div class="header">
<div class="large">Header</div>
</div>
<div class="content">
Content, you should be able to see this when you scroll to top.
</div>
<div class="footer">
<div class="large">Footer</div>
</div>
</div>
I want the content to be positioned below the header when you scroll the top (but hidden when you scroll down, under header) - this works fine...
However I need to remove top: 5em and use something like "inherit the current height of the header" - is it possible without JS?
If it's really not possible without JS, then I can just use JS but I'd rather try and find a solution in pure CSS.
EDIT:
I should note that the reason I can't use top: 5em is because the header will not have a fixed height - an image (for a logo) will be used inside of the text, and that would be set to max-width: 100% so that it shrinks to right width for an iPhone and doesn't expand too much on say an iPad.
See if thats work for you. http://jsfiddle.net/UGhKe/3/
I added another div with the same height but "non-fixed" to simulate your fixed header.
HTML
<div id="body">
<div id="blockHeader"></div>
<div class="header">
<div class="large">Header</div>
</div>
<div class="content">
Content, you should be able to see this when you scroll to top.
</div>
<div class="footer">
<div class="large">Footer</div>
</div>
</div>
CSS
html, body { margin:0; padding:0; }
#blockHeader
{
width:100%;
height: 5em;
}
.content {
position: absolute;
overflow: hidden;
height: 1000px;
background: #936;
z-index: 0;
width: 100%;
}
You can do it using variables(Use SASS or LESS for that). Take a look at the pen.
CODE:
$headerContentVariable: 5em;
#body {
height: 200px;
background: black;
width: 100%;
}
.header {
position: fixed;
top: 0;
background: #369;
z-index: 1;
width: 100%;
height: $headerContentVariable;
}
.content {
position: absolute;
top: $headerContentVariable;
overflow: hidden;
height: 1000px;
background: #936;
z-index: 0;
width: 100%;
}
.footer {
position: fixed;
bottom: 0;
background: #396;
width: 100%;
}
.large {
font-size: 120%;
padding: 2em;
}

Can I stretch an element to the right side of a browser window, from within a centered wrapper?

I'm having some trouble figuring out how to do this. I want to have a wrapper so my site is centered, but one of the header elements needs to stretch all the way to the right edge of the page, but without expanding the width of the page and adding scrollbars.
See here: http://i49.tinypic.com/6rkaxc.jpg (new poster so can't add image)
The blue outline represents the centered wrapper, and the orange box is the header div that I'm trying to get to fit to the right side of the page. I've got it to work using 100% width but it creates a horizontal page scroll since it's making it the same width as it's parent. I want it to expand for users that have higher resolutions so it always fits snug to the right side. I hope this makes sense.
my code looks something like...
<body>
<div id="wrapper">
<div id="header">
</div>
<div id="left">
</div>
<div id="right">
</div>
</div>
</body>
CSS:
div#wrapper {
margin: 0 auto;
width: 1020px;
position: relative;
}
div#header {
height: 150px;
position: absolute;
left: 510px;
width: 100%;
}
div#left {
width: 510px;
float: left;
}
div#right {
width: 100%;
float: left;
}
I'm pretty new to this stuff so if you notice any errors here or bad practices please point them out! Thanks for the help! :)
Since you want your content to be fixed width, a strategy would be to have containers for both left and right contents. This allows you to use width: 100% for the header which will extend to the end without scroll bars. You then make the header relative to the right container. Here is a jsfiddle you can play with.
Note I made the widths smaller so it would fit in my jsfiddle window.
HTML:
<body>
<div id="wrapper">
<div id="leftContainer">
<div id="left">
This is left
</div>
</div>
<div id="rightContainer">
<div id="header">
This is a header
</div>
<div id="right">
This is right
</div>
</div>
</div>
</body> ​
CSS:
div#wrapper {
text-align: center;
width: 100%;
position: relative;
white-space: nowrap;
overflow-x: scroll;
}
div#header {
z-index: 1000;
height: 150px;
position: absolute;
left: 0;
width: 100%;
background: green;
}
div#leftContainer {
float: left;
width: 50%;
height: 500px;
display: inline-block;
}
div#left {
float: right;
width: 260px;
height: 300px;
background-color: purple;
}
div#rightContainer {
position: relative;
float: right;
width: 50%;
height: 500px;
display: inline-block;
}
div#right {
width: 260px;
height: 300px;
background-color: yellow;
}
Try this one. I changed the wrapper width to 80%. Not sure if that's ok. But I works well when expanding the page. Moved the header outside of wrapper and also added background color for clarity.
Note 1: right DIV's margin-top is same size as header DIV's height.
HTML
<div id="outerWrapper">
<div id="header">
Header
</div>
<div id="wrapper">
<div id="left">
Left
</div>
<div id="right">
Right
</div>
</div>
</div>
CSS
div#wrapper {
margin: 0 auto;
width: 80%;
height: 100%;
position: relative;
background-color: #CCCCCC;
}
div#header {
height: 150px;
float: right;
position: absolute;
left: 50%;
width: 50%;
background-color: yellow;
}
div#left {
width: 50%;
height: 100%;
float: left;
background-color: red;
}
div#right {
width: 50%;
height: 100%;
float: left;
margin-top: 150px;
background-color: blue;
}
Hope this helps.
