Keep an Image Always Centered Regardless of Browser Size - html

I am wondering if it is possible to keep an img inside a div always centered regardless of the browser size? By being centered I mean that the left/right sides of the image gets cropped to ensure the image stays centered without modifying the height. Also, is it possible to prevent the horizontal scroll bar from appearing when the browser width is less then the image width?
I'm sure this is really easy to do if my image is located in a background-url tag in CSS, but because this image is being housed inside the SlidesJS carousel the image has to be from an img tag.
At the moment, I have used margin:0 auto; to keep the image centered as long as the browser width is larger then the image. Once the browser width shrinks, the image does not resize with the shrinking browser size. I also have yet to figure out how to remove the horizontal scroll bar when the browser width is too small.
This is what I'm trying to achieve: http://imgur.com/Nxh5n
This is an example of what the page layout is suppose to look like: http://imgur.com/r9tYx
Example of my code: http://jsfiddle.net/9tRZG/
HTML:
<div id="wrapper">
<div id="slides">
<div class="slides_container">
<div class="slide"> <!-- Carousel slide #1 -->
<img src="http://www.placehold.it/200x50/">
</div>
<div class="slide"> <!-- Carousel slide #1 -->
<img src="http://www.placehold.it/200x50/">
</div>
<div class="slide"> <!-- Carousel slide #1 -->
<img src="http://www.placehold.it/200x50/">
</div>
</div>
</div>
</div>​
CSS:
#wrapper {
width: 200px;
margin: 0 auto;
}​

Try this: http://jsfiddle.net/9tRZG/1/
#wrapper {
max-width: 200px; /* max-width doesn't behave correctly in legacy IE */
margin: 0 auto;
}
#wrapper img{
width:100%; /* the image will now scale down as its parent gets smaller */
}
​
To have the edges cropped, you can do this: http://jsfiddle.net/9tRZG/2/
#wrapper {
max-width: 600px; /* so this will scale down when the screen resizes */
margin: 0 auto;
overflow:hidden; /* so that the children are cropped */
border:solid 1px #000; /* you can remove this, I'm only using it to demonstrate the bounding box */
}
#wrapper .slides_container{
width:600px; /* static width here */
position:relative; /* so we can position it relative to its parent */
left:50%; /* centering the box */
margin-left:-300px; /* centering the box */
}
#wrapper img{
display:block; /* this allows us to use the centering margin trick */
margin: 2px auto; /* the top/bottom margin isn't necessary here, but the left/right is */
}

Jeff Hines linked putting image always in center page where ShankarSangoli explained how to achieve this.
img.centered {
position:fixed;
left: 50%;
top: 50%;
/*
if, for instance, the image is 64x64 pixels,
then "move" it half its width/height to the
top/left by using negative margins
*/
margin-left: -32px;
margin-top: -32px;
}

I am not sure about the align center looks proper to me as for the scroll bar.
You can use the following:
overflow-x: hidden;

Adjust width and height of DIV element

I have a page with a vertical navbar on the left side of the page, and a "content" area to the right of the navbar. I want the width of the "content" area to fill the remainder of the screen, and the height to match the navbar height.
Here is what I have so far: jsFiddle
Preferably I am looking for a pure CSS solution to this problem.
Typically, the Faux Columns technique is used to fill in the space that isn't filled with content. You'll need to replace your CSS gradients with images, and it's much easier to set up with fixed dimensions (but still possible with fluid dimensions).
Essentially, you'd need to structure your HTML elements like this:
<div id="header"></div>
<div id="wrapper">
<div id="sidebar"></div>
<div id="content"></div>
</div>
<div id="footer"></div>
Your CSS would do the work for you as far as stretching the content goes:
/* The top part of the rounded container */
#header {
background: url(images/bg_top.gif) 100% 100% no-repeat; /* sit on top */
}
/* The background for your content */
#wrapper {
background: url(images/bg_tile.gif) 100% 0 repeat-y; /* repeat on the right */
}
/* The bottom of your content */
#footer {
background: url(images/bg_bottom.gif) 100% 0 no-repeat; /* sit on the bottom */
}
You'll definitely need to play around with some negative margins to get things to sit perfectly.
Apply a min height to your content area:
#content {
position: absolute;
margin-left: 200px;
width: 100%;
min-height:328px;
}
Check out the updated fiddle: http://jsfiddle.net/hsGN6/6/
It's crude, but it works.

CSS centred header image

I have a header image that repeats across screen, so that no matter the screen resolution the header is always stretched 100%, I have placed the image inside a wrapper div.
Over the top of that DIV I also wish to place the 'logo' such that it is always centred across the top of the screen.
I appreciate this could be done another way and have already tried just having the logo on top of the header in photoshop although i couldn't get the image centred as I would of wished.
Please find my code below:
HTML:
<div id="wrapperHeader">
<div id="header">
<img src="images/logo.png" width="1000" height="200" alt="logo" />
</div>
</div>
CSS:
#wrapperHeader{
position: relative;
background-image:url(images/header.png);
}
#header{
left: 50%;
margin-left: -500px;
background:url(images/logo.png) no-repeat;
width:1000px;
height:200px;
}
Also, I am aware of the properties of margin-left:auto; etc. Although I would be grateful if anyone could explain how to use them appropriately here.
Thanks!
I think this is what you need if I'm understanding you correctly:
<div id="wrapperHeader">
<div id="header">
<img src="images/logo.png" alt="logo" />
</div>
</div>
div#wrapperHeader {
width:100%;
height;200px; /* height of the background image? */
background:url(images/header.png) repeat-x 0 0;
text-align:center;
}
div#wrapperHeader div#header {
width:1000px;
height:200px;
margin:0 auto;
}
div#wrapperHeader div#header img {
width:; /* the width of the logo image */
height:; /* the height of the logo image */
margin:0 auto;
}
If you set the margin to be margin:0 auto the image will be centered.
This will give top + bottom a margin of 0, and left and right a margin of 'auto'. Since the div has a width (200px), the image will be 200px wide and the browser will auto set the left and right margin to half of what is left on the page, which will result in the image being centered.
you don't need to set the width of header in css, just put the background image as center using this code:
background: url("images/logo.png") no-repeat top center;
or you can just use img tag and put align="center" in the div

Position an image from the bottom

I have an image that should be positioned near the bottom of the screen. I have a main image that is the background image and will resize with the browser size. I need the image over the background image to be 20-30px from the bottom no matter what size screen or if the screen is resized. (Image also must be centered.)
I am not sure how to go about doing this. What is the best way to do this?
Here is the code I have tried:
.bottom{
position:absolute;
margin-left: -355px; /* Image is 710 in width */
left:50%;
bottom:-20px;
}
That code has the image centered on the page properly but not 20px from the bottom. Also I have content below the image and I want the content to stay below the image but it currently comes up over the image.
HTML:
<img class="bottom" src="src-path.png" alt="Text" />
<p style="clear:both;"> </p>
<!-- More Content here that consist of img and p tags. -->
I guess to position the image 20-30 px from the bottom you can use css property
margin-bottom:30px; or 20px what ever value suits you.
for aligning at the center use vertical-align:middle Please do share the code that the thing is more clear. Hope I answered it correctly.
CSS Together must look like:-
margin-bottom:30px;
vertical-align:middle;
You better use a CSS file, in which you declare a footer to be at the bottom of your page. Then put your image in your page, with class of that CSS and id of "footer". Clear enough?
Here is the way I finally did this:
CSS:
.image_block {
/* Size of image is where the width/height come from */
width: 710px;
height: 500px;
}
.image_block a {
width: 100%;
text-align: center;
position: absolute;
bottom: 0px;
}
.image_block img {
/*Nothing Specified */
}
HTML:
<div class="image_block">
<img src="src.png" alt="Alt Text" />
</div>

How can I create this centered header with multiple colors?

I want to recreate the following header:
The problem is that the content is centered in the white section. Grey is the background of body and the header is 100% of screen.
What I have now is:
CSS
.top_left {
background:#3c4d74;
}
.top_right {
background:#2f3a5a;
}
.top_center {
background:#3c4d74 url(http://img85.imageshack.us/img85/2816/headerbgo.jpg) no-repeat right top;
height:140px;
}
#page,
.top_center {
max-width:1000px;
margin:0 auto;
}
#page {
background:#FFF;
}
body {
background:#DEDEDE;
}
HTML
<body>
<div id="top-header">
<div class="top_left"></div>
<div class="top_center">
LOGO
</div>
<div class="top_right"></div>
</div>
<div id="page" class="hfeed">
MY content bla bla bla
</div>
</body>​​​​​​
Which you can see working on http://jsfiddle.net/gTnxX/ (I put max width 600px instead of 1000px so you can see it on fiddle).
How can I make the left side soft blue and right side hard blue at any resolution?
To do this you need to be very aware of how positioning works.
The #header-bg is positioned so it falls below #wrapper. It is 100% width, 140px high with 2 divs which both take up 50% of that space and they both get a different colour for left/right.
The #wrapper is relatively positioned to make z-index work, putting it above the #header-bg. Width is set at 600px, and margin: 0 auto; centers it.
The #header is a simple div which has a height set to it and the background it requires.
Content follows the #header in normal flow.
Here is a jsfiddle with the requested behaviour.
http://jsfiddle.net/sg3s/cRZxN/
This even degrades nicely and lets you scroll horizontally if the content is larger than the screen (something I noticed from the original jsfiddle).
Edit:
To make it IE7 compatible I made some changes to fix 2 bugs. I had to add left: 0; and top: 0; explicitly to #header-bg to fix a positioning bug. Made the divs inside #header-bg 49% instead of 50% or else IE7 would not resize them properly and make the right div bump down. To compensate for the small gap that created I made the right div float: right;.

css padding, position text in the upper center of a web sit

I am writing a website in Html using CSS; in my website I have a text logo that I want to place in the top center size of the site, I am using CSS as indicated below
background-color:#4d5152;
position:fixed;
width:970px;
top: 0%;
padding-right:200px;
padding-left:200px;
My question is, how can I position my logo in the upper center and have the left and right size of the logo the same color of the logo without righting the values to the padding left and right; so it will be generic for all computer monitor size and browsers
hope I am clear enough
Thank for the help
Typically, I would write something like this:
HTML
<html>
<body>
<div id="wrapper">
<h1 id="logo">My Company</h1>
</div>
</body>
</html>
CSS
#wrapper {
width:960px; /* Width of the containing 'wrapper' or content area */
margin:0 auto; /* This will center the wrapper. 0px margin on the top and bottom, and 'auto' on the left and right (let the browser decide the amount of margin). */
}
h1#logo {
text-align:center; /* If you don't define a width the h1 will be 100% as its parent (#wrapper). This centers the text. */
}
