Centering a page layout on higher resolutions - javascript

I'm working on a site which has some big images etc to show. On my screen, at 1024 x 768 resolution, it fits the screen completely, going from left to right.
However on my client's screen, who has a bigger resolution, he sees the right part of the screen as blank, and wants me to center the layout rather than have it be left aligned. (I have my margin-left set to 0.)
If I simply increase the margin-left, it will cause a horizontal scrollbar to appear on lower resolutions like mine.
Is there any way to solve this that will work on all resolutions? Or do I have to resort to using javascript which will detect screen resolution, and increase the margin-left if the resolution is bigger than a certain value?

#wrapper { margin: 0 auto; width: 960px; }
this will horizontally center an element with id="wrapper", so if all your content is inside that element, your page will be centered
basically if you apply margin-left: auto; and margin-right: auto; to a block element, it will be centered horizontally

Make a container element around all the elements you want to center and give it an id like id="container" then add a css selector to center it.
#container {
margin: auto
}

how do I make a element the size of the screen but not resize again?

REFERENCE: http://www.templatewire.com/preview/landscaper/
I want to make a web page, and in that page, I want to have divs/sections each the size of the screen.
Now, I mean, the width and height of the monitor, and it won't resize again, and will stay the width and height of that monitor, regardless of the browser size, and regardless of how much content is inside it.
The link shows you what I mean, but I have a 1920x1080 browser window, you can see the top and bottom of the sections above and below it. I don't want the top and bottom of neighbouring sections to be seen if the monitor is very big, nor do I want the section to not be fully visible if the monitor's too small.
Example, say I had 5 sections like in the reference, and my browser window was 1920x1080, the overall height of that document would be 1920*5400.
(I want it to be the height of the screen minus the height on the nav bar.)
You can use Viewport units (the browser window size). 100vh is the height of the screen. If you got sections that bigger than the height of little screen you can use the min-height property and set it to 100vh.
Since you didn't place your code, this is generally example of use case:
section { min-height: 100vh;}

https://developer.mozilla.org/en-US/docs/Web/CSS/length
Good luck!
It appears you're looking for viewport percentage lenghts.
To give any element current viewport's height, in CSS, one should use:
your-selector {
height: 100vh;
display: block;
}
If the element is a <div> or any other element with a default value of block for display, it obviously doesn't need the second rule.
See it working:
your-selector {
height: 100vh;
display: block;
transition: background-color .3s linear;
}
/* let's add a hover, for testing */
your-selector:hover {
background-color: red;
}
body {
margin: 0;
min-height: 200vh;
}
<your-selector>Test</your-selector>
Note: you can also apply viewport percentage lengths to other properties, such as min-height, max-height, etc...
Note: although default viewport is browser window, that's can change. For example, 3d transforms turn any regular DOM element into a viewport for their children, affecting behavior of viewport percentage lengths, as well as behavior of position:fixed in any of their children.

Appending elements increases div's width visually

Whenever I append new element the div's width will increase. I want it to act as a static one. Why don't I just put it to static pixel value? Well I need to have it working on all monitors and resolutions. I need the width of 100% so it goes to the right border and after appending it acts as the static one letting me scroll through the div.
In JSFiddle I set the width to 50% so you can see how it acts(In real environment it will be 100%) Try clicking 10 or more times on Add Tab to see what's happening. After that change the width to static one to see how I want it to behave.
fiddle
Change this code:
.l_tabs {
height: 57px;
display: block;
width: 50%;
/*Changing this to px works as i want it to work but then i have screen resolution problems TRY to set the width to 500px to see*/
background: #474544 none repeat scroll 0 0;
overflow: hidden;
}

Image max-height

I have got a tiny problem, im creating a website and i want to give an image a max-height. The image may only have the same height of another div.
You can check the layout here: http://bit.ly/1OAGsLR
Its about the 1920x1080 image, and i needs to be the same height as the div with class box left to it. If right the image should scale well.
But im trying all i know but i dont get it working, can someone get this working with CSS or do i need to use Javascript for this?
Thanks in advance!
Your image is looking the way you want when the screen width is at or above 1400px. You should consider using css media queries to move or adjust the image at different screen widths. Your layout could easily be handled using a css framework like foundation or bootstrap which would take care of css media query breakpoints for you.
If you are intentionally trying to not use a css framework, I'd check out this css media queries tutorial to get you started.
You need to make your container div wider.
Your container is 1200px wide, and your boxes are 560 + 40 padding wide each.
That means that the max width of you image is 560px.
Now to conserve it's aspect ratio of 16:9, the max height of the image is 560 / 16 * 9 = 315 pixels.
Okay, your main problem is that heights don't like to be defined this way. I have a solution for you that will 'solve' this issue, but its not very pretty and you might want to look into doing this with javascript anyhow. Below is a very rough example mockup.
body > div {
width: 100%;
max-width: 500px;
background: green;
padding: 10px;
position: relative;
}
body > div > div {
width: 50%;
padding: 20px;
}
body > div > img {
position: absolute;
right: 20px;
top: 20px;
max-width: 50%;
/* make sure to fall back to 80% so theres at least some gutter for older browsers */
max-height: 80%;
/* use calc to make the image the height of the relative parent minus padding */
max-height: calc(100% - 40px);
}
<div>
<div>Push<br />Push<br />Push<br />Push<br />Push<br /></div>
<img src="http://placehold.it/350x150" />
</div>
In short, this will place your image to the right of your box, give it a max-height (because positioning can do that) and a max-width (so smaller screen sizes don't freak out).
Now you could easily translate this a more general system where .box + .boxget a absolute position, or you could define a class for the box that has to push content and add that to the first box, making all other boxes absolute.
I fixed it by using JS, im using the following script:
<script type="text/javascript">
function changeheight(){
var Height = document.getElementById('box').clientHeight;
document.getElementById('imagebox').style.height = Height+'px';
}
</script>

How to position the element using absolute position?

I am trying to create a responsive design for my app.
I have a big background image and it will show the full size when user has large screen and only show partial if user uses small screen.
I want to place few elements on my app with absolute position but the problem is I can't lock their top and left value because the screen size changes.
I have something like
css
#background{
background: url('BG.jpg') no-repeat top center fixed;
width: 1900px;
height: 1200px;
}
#element{
position: fixed;
z-index: 5;
top: 50%; //looks fine in 1900 x 1200 screen but position is off on 1200 x 1000
left:70%; //looks fine in 1900 x 1200 screen but position is off on 1200 x 1000
}
html
<div id='background'></div>
<img id='element' src='test.jpg' />
How do I keep the position of the element on the same spot when user has small screen? Thanks for the help!
When using position: absolute, you need to make sure that it has a parent with a position attribute other than the default (which is static). If there is no such parent, the document is the effective parent. For your example, I would advise making the img#element a child of div#background like so
<div id='background'>
<img id='element' src='test.jpg' />
</div>
and then adding position:relative; to the #background css style
#background{
background: url('BG.jpg') no-repeat top center fixed;
width: 1900px;
height: 1200px;
position: relative;
}
The reason relative is used, is because it doesn't take the element out of the document flow (like fixed or absolute would) and as long as you don't specify a top, left, 'bottom', or right attribute to the parent (#background in the case), it will stay in the same location as it would with default positioning.
Edit:
I don't think this will work out of the box for you. You need to figure out how to make the image's width dynamic as well. You can either give it a % based width or use media queries.
Edit 2:
Ia also just noticed you have position:fixed for img#element. Change that to position:absolute. that will make it so that it is positioned relative to the position:relative parent rather than the window.
Consider making a javascript function that calculates the screen width. After that add margin-left to #background equal to ( screen width / -2 ). Make #background width & height - 100%

How to keep text over a huge image in proper position on all resolutions?

In my intro page I have a really big image in height and width to fit all the resolutions (more than 4000px in width) and I set it as below:
#source-image {
width: 100%;
position: absolute;
top: 0;
left: 0;
}
Then, I added some text over that image with these style properties:
.description {
position:absolute;
top:510px;
left:23px;
width:340px
}
And it looks properly (and as I want it to be shown) on my 15.6 inch laptop with 1366x768 resolution.
However when my roommate saw it on his high resolution monitor the description was not on the “right” position. Of course, I understand why this is happening.
My question is how can I keep dynamically the proper position of the description text in all resolutions?
Thank you very much.
Set the distance from the bottom, not from the top. Or set it in %.
EDIT: I've adapted one of my experiments into an example: http://dabblet.com/gist/2787061
The position of the description is set relative to the bottom and the left of the image container (the image is filling its entire container).
In the first case, the distances to the left and the bottom of the image container are fixed, in px.
In the second case, they are in % and change on resizing the browser window.
Basically, the rules that do the trick are
figcaption {
bottom: 5px;
left: 23px;
/* more rules here */
}
in the fist case (fixed distances, in px) and
figcaption.perc {
left: 10%;
bottom: 17%;
}
in the second case (percentage).
Also, please note that you don't need position: absolute or to set the top and the left properties for the image.
However, you do need to set position:relative on the parent of the description box.
For the image to fill the screen horizontally, you need to have margin:0; and padding:0; on the body element and width: 100%; and margin: 0; on the figure element. I've edited my example to reflect these changes http://dabblet.com/gist/2787061
For the image to fill the screen both horizontally and vertically, the easiest way is to not even use an img tag, but simply set the image as a background image for the body and set the height for both the html and the body elements to 100% - example http://dabblet.com/gist/2792929
Be careful for two reasons: one, this will really distort the image and can make it look ugly when resizing the browser window and two, if you need some content below the image you will need to give the the outer element position: absolute and set its top: 100%. Both these two aspects can be seen in the example I've linked to. You can simply remove the content below the image if you don't need it.
use position:relative; for the div that wraps the image, and position:absolute; for the text div
please set percentage
check the example- description box set in horizontal center,
first set position relative into wraper div
.description {
position:absolute;
top:510px;
left:50%;
width:340px;
margin:0 0 0 -170px
}
