I thought I had CSS floats figured out but apparently I don't because I can't figure out why this page is behaving the way it is. I'd like for the photo and status divs to each take up 50% of the screen such that both of them appear on the same line and that line takes up 100% of the screen. But what is happening is that the "Stats" div renders below the "Photos" div. The only way I can get them to render on the same line is to reduce their respective widths to 49% (or lower) but then there's a slight gap between the right edge of "Stats" and the edge of the screen. There's something that's taking up additional room but I don't know what it is and I don't see anything in Chrome's Dev Tools. By the way, reset.css is just Meyer's reset.
Thanks.

I found my error. If add additional padding to each of the elements, that creates the problem. I left that out of my question so that code shown above will work. My bad.

it will surely be a trivial problem but I have been hitting my head for a long time.
The problem is simple, that is: I have an area with specific dimensions (450x800px) that I would like to always fit the height of the screen.
I am attaching here the sample code I am working on, thank you very much to those who can help me!
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="height=device-height, initial-scale=1.0">
<title>Page Title</title>
<style>
html, body { height: 100%; margin: 0;}
.full-height { height: 100%; background: yellow;}
</style>
</head>
<body>
<div class="full-height">
<div style="width:450px; height:800px; margin-left:auto; margin-right:auto; background-color:#FD0F13">I am a DIV that will stretch to fit the whole width and height of the browser window!</div>
</div>
</body> </html>
I created a simple example to showcase the idea of having an absolutely positioned element with left and right set to 0 but with very different results in latest Chrome and Safari.
Based on the comments to this question and this answer, I would think it would work consistently based on how it's outlined in the CSS spec, but it doesn't. Why is this the case?
I'm aware that setting a specific width will resolve, but 1) why the difference cross-browser, and 2) is there a better way to center than specifying explicit width?

Basically I am using the "Tryit Editor" from the W3 website and
this is the code I started out with
<!DOCTYPE html>
<html>
<head>
<style>
body
{
background-image:url("img_tree.gif"),url("img_flwr.gif");
background-color:#cccccc;
}
</style>
</head>
<body>
</body>
</html>
I wanted to change the background color and background images so that they were only found on a div, not on the whole page. I also wanted to move the div around the page. I was able to make the div with the background elements, but I wasn't able to move it around the page. I used the following code, thinking that
top:150px;
left: 150px;
would have caused the div to change position
<!DOCTYPE html>
<html>
<head>
<style>
div
{
position=fixed;
top:150px;
left: 150px;
background-image:url("img_tree.gif"),url("img_flwr.gif");
background-color:#00dccc;
height: 200px;
width: 200px;
}
</style>
</head>
<body>
<div>
</div>
</body>
</html>
Alas, the div did not change position. What gives?
Thanks! :]
You have an equals sign rather than a colon in your position declaration which is causing the page to ignore it. Change that and it'll work!
EDIT: Thanks for fixing my awful terminology Pavlo, can't believe I did that :P
Your code is wrong. It should be
position: fixed;
I cannot seem to remove the spacing between the top of the page and the <div> in this example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Index</title>
<style type="text/css">
html, body{
padding: 0;
margin: 0;
}
#container{
background-color: #808080;
}
</style>
</head>
<body>
<div id="container">
<div id="inner-container">
<h3>Index</h3>
</div>
</div>
</body>
</html>
I have narrowed it down to this line:
<!DOCTYPE html>
It seems removing this aligns the <div> to the top of the page. I can't see a way in CSS to achieve the same thing.
remove the margin from your <h3> as well
h3 { margin-top: 0 }
DEMO
Margins collapse into each other.
The top margin of html (0), body (0), #container (0), and h3 (not 0) merge into a combined non-zero top margin between the first content and the edge of the window.
Set h3 { margin-top: 0 } to remove it.
(Although you should start your document with a heading (h1) not a sub-sub-heading (h3).)
Actually Default Margin Of H1 to H6 is the problem you are facing so overriding this value will solve your problem.
h3 { margin-top: 0;margin-bottom: 0; }
Extra Info:
You also might want to look into using a CSS reset script before starting a project so you don't have to worry about little things like this.
I have the following code which, as expected, shows a grey rectangle in both Firefox and IE. As soon as I add a DOCTYPE (HTML 4.01 Transitional) in front, it shows only a blank page. The online validator says the document is OK. What is wrong? Should I care about DOCTYPE?
<html>
<head>
<title>Title</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<style type="text/css">
#gallery
{
width:750;
height:548;
background-color: #f0f0f0;
}
</style>
</head>
<body>
<div id="gallery">
</div>
</body>
</html>
You need to specify the units for your width and height. I assume you're going for pixels so:
#gallery
{
width: 750px;
height: 548px;
background-color: #f0f0f0;
}
You haven't specified the units of measure for the height and width attributes in your CSS. Without a DOCTYPE the browser will attempt to render the page as best it can (QUIRKS mode), in your case I think it probably guessed the correct units. By adding the DOCTYPE you have told the browser to follow a very specific set of instructions when rendering the page - no guessing that you wanted pixels instead of percents.
Your CSS was buggy.
width:750px; /* PX!! */
height:548px; /* PX!! */
Then add the doctype.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Title</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<style type="text/css">
#gallery
{
width:750px;
height:548px;
background-color: #f0f0f0;
}
</style>
</head>
<body>
<div id="gallery">
</div>
</body>
</html>
The definition of height and width should be in pixels, em's or percentages, e.g:
width: 750px;
height: 548px;
