Creating a very simple webpage for DIV testing. I have a DIV that creates a header at the top of my page, which is fixed so it does not scroll off the page. Within this DIV, I have an H1 header that I want to be centered vertically, left justified but away from the left edge of the page by a certain amount (20 pixels).
Here is my code:
CSS:
body {
font-family:"Calibri";
margin:0px;
}
div.header {
top:0px;
left:0px;
width:100%;
height:50px;
position:fixed;
background-color:#7fc7f4;
border-bottom:thick double black;
z-index:2;
}
h1 {
color:black;
margin-left:20px;
font-variant:small-caps;
}
HTML
<!Doctype html>
<html>
<body>
<div class="header">
<h1>Website Heading</h1>
</div>
</body>
</html>
When it renders on my C:\ drive, the H1 text is at the bottom of my DIV block. I copy the files to a network drive, and open it from there. When it renders from the network drive using the same browser on my computer (IE9), it is centered all on its own.
For my C:\ drive, I tried adding the following to my H1 in the CSS:
h1 {
color:black;
line-height:50px;
vertical-align:middle;
margin-left:20px;
font-variant:small-caps;
}
This has absolutely no effect when rendered on my C:\ drive. Rendered on the network, it is still centered as I want it, just as it was before I added these lines which appear to be ignored. I obviously want this to be consistent in both the C:\ drive and network locations, so I know that my pages are working properly when both building/testing and deploying for all to consume. It also has to be consistent across Chrome and Firefox as well.
Thoughts anyone?
One thing I'm not sure about is where to add these lines of code. Do I add them to the H1 tag as I have done, or do I add them to the DIV tag? Does it matter? I have tried both, and it doesn't seem to make a difference.
You'll have to forgive me, as I am relatively new to CSS, and am trying to get a better understanding. I have searched through the answers on similar topics on here, and all the suggestions that people have given don't seem to work. So I am hoping that I am just missing something simple.
Ensure you 0 out the other H1 margin values:
h1 {
color:black;
margin:0 0 0 20px;
font-variant:small-caps;
}
You should be implementing a normalize CSS file to baseline your HTML elements if you aren't already.
For example, I use http://html5boilerplate.com/
What you're looking for is 'line-height' on the H1 element, the following makes the line-height of the h1 element the same height as the containing div, giving it the effect of vertically aligning in the middle.
You'll also need to remove the margins that are on the h1 element by default, by using margin:0;
h1 { line-height:50px; margin:0; }

This has probably been asked a million and one times, but I would appreciate it if someone could explain the behavior of the divs to me..
I have a container div which I am aligning in the center of the page, which has a gap between the top and the top of the page. I want it to be flush against the top of the page. I am assuming that there is some sort of margin or padding that I need to remove but I can't think what it could be. Even with nothing in the div there is still a gap.
<body>
<div id='mainContent'>
</div>
</body>
body
{
background-color:black;
background-image:url("img/background.jpg");
background-repeat:repeat;
}
#mainContent
{
width:1200px;
height:500px;
background-color:#FFFFFF;
margin-left:auto;
margin-right:auto;
margin-top:0px;
}
Here is a JSFiddle to give you an idea of what I mean.
Can someone please explain why the div is pushed down as it is? Is there a robust solution that doesn't affect any content that is put in the div??
NOTE: If the screen width is smaller than the div width, there will be a gap on the left hand side aswell.
You need to reset the default margin of the body that is 8px aprox.
body,html {
margin:0;
padding:0;
}
The Demo http://jsfiddle.net/H76bq/3/
For default all elements has some properties:
http://www.w3.org/TR/CSS21/sample.html
You can reset this in your own css.
You could use a star selector and reset everything so that you can set everything yourself:
* { margin: 0; padding: 0; border: none; }
Or if you wanted to use a master reset stylesheet you could use Jonathan Neal's Normalize CSS via Google CDN.
Normalize.css is a customisable CSS file that makes browsers render all
elements more consistently and in line with modern standards. We researched
the differences between default browser styles in order to precisely target
only the styles that need normalizing.
Just put this in your head:
<link rel="stylesheet" src="//normalize-css.googlecode.com/svn/trunk/normalize.css" />
Add margin: 0px; to body like below. The reason is because body by default introduces a margin.
body{
background-color:black;
background-image:url("img/background.jpg");
background-repeat:repeat;
margin: 0;
}
Demo Fiddle
It can also been caused by line-height property.
So set the line-height to as you wish!
I had similar problem and I solved it by setting negative margin. You could test the below setting.
#mainContent {... margin-top:-25px;}

<a href="lcars.jfx.php" class="leftbuttons buttonlinks antibutton">
LCARS Locomotive O.S.
</a>
My problem is the text label in the graphic. I'm using this button design all over my site, with only the text and its size varying. When I originally designed the system (on page: http://www.fccorp.us/development/index.php and then again on http://www.fccorp.us/development/index.fccorp.php), I used the margins & padding CSS controls to get the text centered vertically within the button. But that depended on a static font height. Now I want to use a taller font and can't get the thing to auto center height wise. I tried
.leftbuttons {
width:335px;
height:40px;
padding:**auto**
20px **auto**
45px; font-size:1em;
border-style:solid;
border-width:0px;
font-family:Arial;
font-weight:900;
margin-left:10px;
margin-right:20px;
margin-top:20px;
margin-bottom:20px;
text-align:center;
display:inline-block;
background-image: url(http://img580.imageshack.us/img580/1461/lcarssitebutton.png);
}
But all that ended up doing was chopping the image up.
I'm using the .antibutton to try to override a few details from the other classes in order to get what I'm trying to get. If I can solve the text vertical-align problem (or some nice coder here can figure out what the heck I screwed up), I also want to get the button's bottom aligned even with the text line.
Any thoughts?
Why don't you just add a line-height: to your unique cases?
for example, i added line-height: 40px; to a.buttonlinks and it centers vertically just fine.
I've been implementing Mega Menu Reloaded On to my website, and I am unable to properly align the div tags on different screen resolutions!
Here's: what it should look like
Here's: what it looks like after I've rewritten parts of the css of Mega Menu.
I've tried for a few hours to fix this issue, but as a beginner to css I can not seem to manage to fix it.
I believe this is the css needed pertaining to its placement
.megamenu_fixed {
width:960px;
height:44px;
position:fixed;
right:0;
margin:0 auto 0 -480px;
z-index:2;
background-image:url("../img/bg.png");
background-color: #3d3d3d;
padding-left:12px;
}
.megamenu {
position:absolute;
margin:0;
width:960px;
font-size:0.982em;
list-style:none;
padding:0px;
line-height:38px;
font-weight: bold;
display:block;
list-style:none;
top:41px;
padding-left:42%;
}
and here's the code of it's position with the correct placement
#nav-main { right:0; top:55px; list-style: none;}
#nav-main li {list-style: none; float:left; position:relative; padding-left:20px; }
Thanks in advance for any help, or pointing me in any right directions. :)
try using relative instead of absolute positioning.
also, failing that, try specifying left as a percentage (i.e. approx 50% is where the menu starts), and width also as a percentage (100% should make it use only from the left-most point of the div to the right-most side of the screen. if not, try 50% width).
The problem is in your HTML, not your CSS (I think. Well, I fixed the part where 'Adults' was hiding, that was a syntax error)
the span where Adults is declared is mistyped. I replaced <span class="drop"><adults< span=""> (problem code) with <span class="drop">adults</span> and 'Adults' displays properly. However, it is a little squashed to the right, but I believe that would be because of the images top left of the page of 'bad' version, which are not there on the 'good' version
PS: I've left the old answer there as people may have similar issues, where it is in fact the CSS at fault. If you think it's considered "off-topic" let me know, I'll remove it
UPDATE: Oh, and something I forgot to mention, to fix the squashed megamenu, just edit the location in the CSS, that should bring it back to normal
Alternatively, you can scrap div (almost) entirely and use tables instead. can be confusing sometimes, but in my opinion it's totally worth it. You just can't merge/split cells (to split just create a table within a table). Use microsoft word or openoffice writer or something like that and create tables within tables for graphical "base layout" to help you figure out the necessary code. Here's a starting point: Formatting layout with tables on gitHub
Currently, I am modifying a css document to make a website compatible in IE 6 and including it using a conditional statement. Everything is slowly starting to look as it should EXCEPT....I can't seem to modify the height of the background image in the css below. I can make it bigger by increasing the height, but decreasing the height does not make it smaller. The original image is quite thin, so I don't see why this is a problem.
#title{
text-align:left;
margin-left:170px;
margin-top:0px;
background-image:url(images/gradient.jpg);
background-repeat:repeat-y;
padding: 0px 0px 0px 0px;
width:680px;
height:42px;
color:white;
font-family:Helvetica, Georgia, "Times New Roman", Times, serif;
position:relative;
top:0px;
}
You can see in the attached image that the red gradient background image underneath the cork header image is too big and the text inside is too large also. However, no matter what I change in the css, it doesn't seem to alter anything.

The div tag is:
<div id="title">
<h1>
Historia </h1>
</div>
Any thoughts as to why I can't seem to change this?
I would try first by using firebug lite for IE, that way at least you aren't guessing whats going wrong and you can identify the padding/height/etc;
My thought is that the height is simply being stretched by the h1 element (perhaps something else sneaking in too), thats my best guess as I don't have IE6 to test, but since your height is defined for the #title it must be whats inside of it that stretches it. Try setting overflow: hidden; for the #title see if that helps, or at least shows your 42px height.
http://bodegacooperativacigales.com/historianew.html
Try firebuglite, and view the element, it will show you what to get rid of in IE.
EDIT
to define your h1 simply do this:
#title{
text-align:left;
margin-left:170px;
margin-top:0px;
...
}
#title h1 {
height: 20px;
margin: 0; // remove margin
padding: 0; // remove padding to check if this is the issue
}
in your IE6 CSS sheet. Don't set a background image into the h1. The above piece is separate from your #title css definition.
I think you might be having issues regarding the height due to the child element creating overflow. Try adding the following rule to prevent the parent element from displaying any overflow:
#title {
overflow: hidden;
}
I'm using VS2010,C# to develop my ASP.NET web app, I'm using a .js file to display some small tool tips in my program, there is a CSS file also that should be used in my ASPX files so that this tooltip is displayed correctly, but when I use this CSS all my page (including tables) are displayed at left side of page while I've aligned them to be at the center of page, I'm not an expert in CSS files, how can I fix this problem, here is my CSS file:
* {margin:0; padding:0}
body {font:12px/1.5 Tahoma, Arial, Helvetica, sans-serif; background:#FFF}
#text {margin:50px auto; width:500px}
.hotspot {color:#900; padding-bottom:1px; border-bottom:1px dotted #900; cursor:pointer}
#tt {position:absolute; display:block; background:url(images/tt_left.gif) top left no-repeat}
#tttop {display:block; height:5px; margin-left:5px; background:url(images/tt_top.gif) top right no-repeat; overflow:hidden}
#ttcont {display:block; padding:2px 12px 3px 7px; margin-left:5px; background:#666; color:#FFF}
#ttbot {display:block; height:5px; margin-left:5px; background:url(images/tt_bottom.gif) top right no-repeat; overflow:hidden}
#tt is set to position: absolute. This is probably the cause of your problems since you are not telling it what position you want so I suspect it is defaulting to top left.
What CSS are you using to align things to the center? And what is your HTML structure? I am assuming that #tt is ta main container on your page...
To actually find out which part of your CSS is wrong though then the easiest way of doing it is to just remove each line/property from your CSS file and retest until the positioning stops dying.
Also if that CSS is there purely for your tooltip then you probably shouldn't be using a * selector. Something more specific like .Tooltip * would minimise any interference from anyting outside.
And in general if styles are meant to only apply to one given piece of content I would use a class (or id) on that content as a prefix to every selector to guarantee that you cannot possibly change anything outside of that.
Going on your code and comments, all I can see that would be effecting the layout of your page is that you are resetting all the margins and padding on your elements using the style
* { margin: 0; padding: 0 }
Also since you are not properly centring your elements (using a wrapping <div> with a fixed width and margin: 0 auto;, then it seems as though it is just your margins and padding that are now off.
