Positioning an image behind a centered div - html

My site has a 900px div #content that is centered with margin-left: auto and margin-right: auto. I have an image that I need to display behind the div which will partially overlap #content.
The image is set to display as block at present and I can get it to where it needs to be, but it doesn't allow #content to draw over the image. I can get #content to display over the image with position: absolute however this prevents the use of margin-left / margin-right auto to center.
My current positioning, which gets it where it needs to be is:
img#watermark
{
margin-left: auto;
margin-right: auto;
display: block;
padding-left: 900px;
}
#content just needs to appear over the watermark.
Help greatly appreciated.

html:
<img src="http://upload.wikimedia.org/wikipedia/en/2/24/Lenna.png" />
<div></div>
css:
div {
margin:auto;
width: 512px;
height: 512px;
background: rgba(0,0,0,.4);
position: relative;
}
img {
position: absolute;
left: 50%;
margin-left:-256px;
}
http://jsfiddle.net/Db2cw/

the solution is to have a surrounding div on the #content div, and that surroinding div positioned absolutely and with a defined width and height.
Ex:
html:
<div id="outter">
<div id="image"><img src="something.jpg" /></div>
<div id="contentOutter">
<div id="content">the content here</div>
</div>
</div>
CSS:
#outter {
width: 1000px;
height: 300px;
position: relative;
}
#image {
width: 1000px;
height: 300px;
position: absolute;
}
#contentOutter {
width: 1000px;
height: 300px;
position: absolute;
}
#content {
margin: 0 auto;
width: 900px;
}
Example here: http://jsfiddle.net/qwEhv/

"I can get #content to display over the image with position: absolute however this prevents the use of margin-left / margin-right auto to center."
What you might need to do here is to have an additional div - call it #contentWrapper for example and center it using margin-left and right, set position to relative. Put div #content inside the wrapper div and position absolute. This should allow you to make #content look centered.

Force responsive <img> to expand to parent <div>

for clarity, see codepen: http://codepen.io/anon/pen/QyaLPb
I want to create an image with an overlay. The overlay should be the same size as the image, however because of the width: 100% and height: auto for both the .imagecontainer and img, they don't have the exact same height. The overlay now has a few pixels more height than the img. You can see the .imagecontainer has more height than the img inside (red background showing at the bottom). I need the imagecontainer and img to be responsive, so setting a fixed height is not really an option. How do I solve this?
HTML:
<div class="wrapper">
<div class="imagecontainer">
<img src="http://www.kleinewolf.nl/uploads/fancybox/8f5b7a59-32b7-4582-868b- e2ff1f3e41a2/2835832130.jpg">
<div class="overlay">
</div>
</div>
</div>
CSS:
.wrapper{
width: 400px;
padding: 40px;
}
.imagecontainer {
width: 100%;
height: auto;
overflow: hidden;
background: red;
position: relative;
}
.imagecontainer img {
width: 100%;
height: auto;
}
.overlay {
position: absolute;
top:0;
left:0;
width: 100%;
height: 100%;
background:rgba(0,0,0,0.8);
display:none;
}
.imagecontainer:hover .overlay {
display:block;
}
If you're speaking of the red border below the image.
Add to your .imagecontainer img: display: block. That should solve the problem...

Added line-height:0; to your container div. Images contained by parent divs usually tend to take margins from other elements, and line-height and font-size are usually a problem. Good luck!

html, width 100% and padding

I have a problem with margins. I want to have image inside div element. Height should be of the image, but width should be of the parent div minus padding.
<div class="inner">
<img width="100%" src="http://pawelek-moj-aniolek.blog.onet.pl/wp-content/blogs.dir/505303/files/blog_bg_734362_1406866_tr_morze.jpg" alt="There is no image"/>
</div>
and styles
.inner {
width: 100%;
height: 100%;
margin: 10px;
position: relative;
}
.inner img {
width: 100%;
}
and the problem is easy to see on the image.

I want to have 10 pixels of white place around each side of the image
Remove width:100% from the inner class. Update your CSS like below.
.inner {
height: 100%;
margin: 10px;
position: relative;
}
DEMO
I would use another div to wrap the image and give:
padding:10px;
insteed of margin.
here is a demo: http://jsfiddle.net/f6jju2mn/
Remove the width:100%; for inner class
.inner {
height: 100%;
padding: 10px;
position: relative;
}

Position div tag at the bottom right of an image

I am trying to position an div element at the bottom right of an image, that is inside a container element. I set position relative to the container, and position absolute to the inner div, but it does not work. Here is the (http://jsfiddle.net/ZC84G/). Please, help.
<div class="container">
<div class="icon"></div>
<img src="/images/someImage.png" />
</div>
CSS:
body {
background-color: black;
}
.container {
position: relative;
}
.container img {
max-width: 75%;
max-height: 80%;
}
.icon{
background-image: url('http://icons.iconarchive.com/icons/iconfactory/star-wars-lego/32/Biggs-No-Helmet-icon.png');
width: 31px;
height: 31px;
position: absolute;
bottom: 5px;
right: 5px;
}
This is because by default div has block display mode, and it's width is 100% of the parent container. Try to add display: inline to .container
.container {
position: relative;
display: inline;
}
Here's the corrected jsfiddle: http://jsfiddle.net/ZC84G/4/
Your container div has no width and height set. And since a <div> is a block-level element by default, it will be set to 100% width ie expand to however much horizontal space is left.
Plus, you're also constraining your image size:
max-width: 75%;
max-height: 80%;
If you replace the img CSS with:
max-width: 75%;
max-height: 80%;
It works fine, and as expected: http://jsfiddle.net/ZC84G/3/
I've modified your CSS on the image a bit.
Basically, I set it to scale properly to the size of its container, and now it sits where I think you wanted it. The way you could find this yourself in the future would be to inspect the element by using right click from your browser, and looking at the size of the different elements to see what was expanding larger/smaller than it should.
.container img {
max-width: 100%;
height: auto;
}

absolute position div disappers inside parrent div

I am trying to put simple divs and arrange them, but my child div disappearing from parent div even though I am using parent div with relative and child div with absolute positioning. I want connect_us_01 and registeration divs insideheader_block1. I am working towards responsive webdesign. Many thanks.
JSFiddle
<div id="header">
<div id="header_block1">
<div id ="registeration">reg</div>
<div id ="connect_us_01">social media</div>
</div>
<div id="header_block2">
<div id="crown_logo">logo</div>
<div id="nav">navigation</div>
<div class="contact_No_01">020324234233</div>
</div>
</div>
css
#header {
position: relative;
width: 100%;
background-color: #ff6a00;
}
#header_block1 {
position: relative;
margin: 0 auto;
width: 90%;
background-color: pink;
}
#header_block2 {
margin: 0 auto;
width: 90%;
position: relative;
background-color: aqua;
}
/*----social media & connect us block*/
#connect_us_01 {
position: absolute;
width: 300px;
height: 50px;
right: 0;
background-color: blue;
}
#registeration {
position: absolute;
left: 1px;
width: 200px;
height: 50px;
background-color: brown;
}
Elements with position: absolute are taken out of the content flow, meaning they have no inherent height. Since the children have no height, the parent gets no height either, rendering the children invisible. You could resolve it by giving the parent a static height (as in, for instance, height: 100px), but that's not very practical and not responsive at all.
What you're looking for isn't position: absolute; it's float: left and float: right. Apply those properties to the children and give the parent overflow: hidden (or whatever method of clearing floats works best with your layout) and it'll work just fine.
To show block you refering to just add to #header_block1 a height parameter also.
#header_block1 {
position: relative;
margin: 0 auto;
width: 90%;
height: 50px;
background-color: pink;
}

CSS centered divs side by side

I have this following chunk of my page.
Style:
.featuredcontainer {
width: 450px;
height: 700px;
margin-left: auto;
margin-right: auto;
position: relative;
right: 160px;
top: 30px;
border: 1px groove grey;
}
.navcontainer
{
margin-left: auto;
margin-right: -8px;
position: relative;
top: 75px;
height: 600px;
width: 300px;
}
And example HTML:
<div class="featuredcontainer">
content
</div>
<div class="lessonnavcontainer">
menu
</div>
When the page is displayed. the navcontainer is to the right of (as it should) but under the featuredcontainer. When I move the navcontainer up using relative positioning, it looks right, but there is a bunch of empty space at the bottom of the page. What do I do?
Surround your two divs with a "wrapper" div like so:
<div id="wrapper">
<div class="featuredcontainer">content</div>
<div class="lessonnavcontainer">menu</div>
</div>
Then to center them, add margins to the wrapper:
#wrapper { margin: 0px auto; }
Then to have the two divs be side by side, add a float:
.featuredcontainer { float: left; }
.lessonavcontainer { float: left; }
In order for the centering to work, you need to declare a width on the wrapper:
#wrapper { width: 800px; }
Put both the nav and the featured containers into another wrapper div.
HTML
<div class='wrapper'>
<div class="navcontainer">
menu
</div>
<div class="featuredcontainer">
content
</div>
</div>
And get rid of all the relative positioning. Relative positioning is not recommended for basic layout issues like this. Use floats instead. The wrapper should have a fixed width, which allows it to be centered properly with margin: 0 auto.
CSS
.wrapper{
width:752px;
margin: 0 auto;
overflow:auto;
}
.featuredcontainer {
width: 450px;
height: 700px;
float:left;
border: 1px groove grey;
}
.navcontainer{
float:left;
height: 600px;
width: 300px;
background:#ff0;
}
JSFiddle http://jsfiddle.net/5w5SC/
Use the float property. Using float, css can position divs next to each other horizontally.
.featuredcontainer {
width: 450px;
height: 700px;
margin-left: auto;
margin-right: auto;
position: relative;
right: 160px;
top: 30px;
border: 1px groove grey;
float: left;
}
.navcontainer
{
margin-left: auto;
margin-right: -8px;
position: relative;
top: 75px;
height: 600px;
width: 300px;
float: left;
}
Thats a starting point, try to use float left or float right and see what happens. Fiddle with it until it looks exactly how you want it.
To get them side-by-side you need to add the float attribute in the CSS. To get them to resize with page width you need to add relative widths to them. To center them on the page (horizontally) you need to put the divs inside a relative positioned div in the html. Here is a fiddle. http://jsfiddle.net/Ne5zs/
Be sure to introduce a clearfix (there are many versions of this technique) on any floated object; then center their containing block element using margin: 0 auto.
