How to position text over an image with CSS
(8 answers)
Closed 7 years ago.
I'm creating a webpage for my photography and basically I'm trying to create div boxes that contain the images, with a div for text displayed over the image. For some reason I cannot work out how to make the text div position from the image div. For example, currently "top: 8%;" positions the text 8% from the top of the page not the top of the image div, despite the fact that the text div is withing the image div in the code and positioned relatively.

This is a frequently asked question. Your answer: How to position text over an image in css . Jsfiddle: http://jsfiddle.net/EgLKV/3/
HTML:
<div id="container">
<img id="image" src="http://www.noao.edu/image_gallery/images/d4/androa.jpg"/>
<p id="text">
Hello World!
</p>
</div>
CSS:
#container
{
height:400px;
width:400px;
position:relative;
}
#image
{
position:absolute;
left:0;
top:0;
}
#text
{
z-index:100;
position:absolute;
color:white;
font-size:24px;
font-weight:bold;
left:150px;
top:350px;
}
Just set the z-index in your CSS. Higher numbered elements appear above lower numbered elements. While you can just give elements contiguous whole numbers; generally, you'll want to provide large gaps between lower and higher elements in case you need to add additional elements or change the layering of elements.

I am helping a student with a project and we are going through a tutorial. The tutorial is here:

The issue is we can see the block for the text when we inspect the page in Chrome, but it is not displaying the text over the image. All we see is the outline of the div where it is located. We have researched how to get this working and also followed the tutorial correctly. Also we have compared our code to the tutorial and can't see where the disconnect is. Any ideas? At this point a solution that works instead of what is in the tutorial will be fine as well.
I am a new css programmer and there is a very annoying problem in my code. when I put the grey bars in they are not touching the left side of the screen they touch the right side but not the left side and I do not know why there is nothing in my code that is stopping them so I do not know why it would be doing that please help me fix it thanks! (the big white space in the middle is supposed to be there it is for a picture.)

By default the body on the page has this css:
body {
display: block;
margin: 8px;
}
body:focus {
outline: none;
}
at the top of your css file just add:
body {
margin:0;
}
this way you're working with 0 margins to begin with.
Margins of <body> don't matter because those grey bars are absolutely positioned to the right therefore they stick to the right side of <html> element. If the screen resolution (the width of your screen or window) is bigger then the width: 1870px;, they are gonna stick to the right side and leave an empty space on the left.
If you want those grey boxes to always stick to both sides of your screen, use width: 100%; or no width and left: 0; instead:
.connect {
background-color: #6b6b6b;
position: absolute;
top: 340px;
right: 0;
width: 100%;
height: 40px;
border: 3px solid #6b6b6b;
}
or
.connect {
background-color: #6b6b6b;
position: absolute;
top: 340px;
right: 0;
left: 0;
height: 40px;
border: 3px solid #6b6b6b;
}
Both will stretch the element to the width of their parent element.
But it is good to set the body's position to relative and get rid of its default margins. In my opinion, you shouldn't use the <html> tag for styling. It will make those absolutely positioned grey boxes stick to the sides of <body> and not <html>:
body {
margin: 0;
position: relative;
}

you forgot for responsive view as
<meta name="viewport" content="width=device-width, initial-scale=1">
the issue is mentioning values in px. These fixed values wouldn't change on resolution change. whereas values like em and % would change on resolution change. Also, we have responsive frameworks to do the task for us. We need to make use of media queries.
Also we need to add the meta tag
<meta name="viewport" content="width=device-width, initial-scale=1">
I need to vertically align with CSS multiple elements inside my header.
At the moment, I am using this structure:
-Header
-Content div (This only set my width to 940 with paddings of 10px each side)
-Element 1 (Height: Known, 50px)
-Element 2 (Height: Unknown, bigger fonts)
-Element 3 (Height: Unknown, smaller fonts)
So I need to vertically align to the middle (50% of my header - size of the element) all of my elements and I need to make it cross-browser compatible...
I've found some suggestion by searching such as using a floater div, however I had a hard time trying to align all of my elements since they are not all of the same size...
EDIT
As requested, here is my HTML and CSS:
HTML:
<!DOCTYPE html>

<body>
<header>
<div class="content">

<ul>
<li>Accueil</li>

<li>Notre compagnie</li>
<li>Nous joindre</li>
</ul>
</nav>
<div id="lang">English</div>
</div>
</header>
</body>
</html>
CSS:
body {
margin: 0;
background-color: #336699;
}
header{
background-image:url('../IMG/bg_top.png');
height: 90px;
}
nav > ul{

Try these suggestions from Smashing Magazine:
http://coding.smashingmagazine.com/2013/08/09/absolute-horizontal-vertical-centering-css/
Specifically, try this code, using the TOP, LEFT, RIGHT, and BOTTOM properties to position your elements:
HTML
<div class="magix">
magix!
</div>
<div class="more-magix">
More Magix!
</div>
CSS
.magix{
background: red;
bottom: 0;
height: 100px;
left: 0;
margin: auto;
position: absolute;
top: 0;
right: 0;
width: 100px;
}
.more-magix {
background: blue;
bottom: 0;
height: 100px;
left: 0;
margin: auto;
position: absolute;
top: 500px;
right: 0;
width: 100px;
}

I'm working on a brand new website and I'm trying to just get the basic layout going. I am using the ASP.NET MVC 4 generated HTML and I would like to get the DIV named body to fill the available space after making room for the header and thus anchoring the footer to the bottom of the browser window. However, what I'm getting right now is three panels just stacked on top of each other.
I would like a solution that would work if the browser supported HTML5 and one if it didn't
Please note I've inlined comments in the CSS to try and explain what I've tried.

Just snap the header and footer at the bottom of the page using fixed positioning.
header, footer{ position:fixed; left:0; right:0; z-index:1; }
header{ top:0; }
footer{ bottom:0; }
Then you can give your body the background your div#body had before. The div gets no background and will expand as much as needed.
div#body{ background:none; }
body{ background:#eee; }
This will look like the div would fill the remaining space of the page. Finally give your header and footer a background so that you can't see the background of the body under it.
header, footer{ background:#fff; }
By the way I would suggest removing body margins. body{ margin:0; }
I believe it's a bit impossible to do that with just CSS. You can make a webpage with 100% height like this:
html{
height: 100%;
}
body{
height: 100%;
}
#body{
height: 100%;
}
And then for header, body and footer you can do like this:
header{
height: 100px;
left: 0;
position: absolute;
top: 0;
width: 100%;
background-color: #f00;
}
#body{
bottom: 100px;
left: 0;
position: absolute;
right: 0;
top: 100px;
background-color: #fff;
}
footer{
bottom: 0;
height: 100px;
left: 0;
position: absolute;
width: 100%;
background-color: #ff0;
}
It might work for a bit, but it'll break at some point. When you resize your browser, it'll be running out of room for your #body. If you want a better solution, you should use javascript. In your javascript, calculate how much space you have for your #body, then either adjust the height of header and footer. Or adjust the #body instead.
