I'm new at this and I don't know why the text inside my h1 tag goes to the right when I zoom in.
Here's the CSS code:
h1 {
font-family: 'Raleway', sans-serif;
border-bottom: 1px solid black;
border-top: 1px solid black;
margin-right: 500px;
margin-left: 500px;
text-align: center;
}
Also, I didn't use <div> because I didn't know what it was for when I began to code. I tried to change it but everything is build around my current technique.
Thanks.
Seeing as you are just beginning to code - this looks great!
I did the same thing when I first started and I'm pretty sure most people do. But Like the comments say - {margin: 0 auto} works best.
Divs are very, very important.
Use chrome's development tools - This is a good way to add and remove CSS rules quickly.
View -> Developer -> Developer Tools.
Navigate to the header through the collapsable menus, click it and note the associated rules on the right. Uncheck Your margin left and right to test the CSS rules.
You need to remove your margin-left: and right 500px;
I would STILL suggest something like this
<div id="container">
<h1> Your Header </h1>
</div>
This way, you can target JUST the h1 in the div of container in your css
#container h1 {
text-align:center
}
#container{
margin: 0 auto;
}

Preface: I've read lots of articles about images inside a div having a strange space around them, etc.
Example #1: Unwanted padding-bottom of a div
Example #2: https://developer.mozilla.org/en/Images,_Tables,_and_Mysterious_Gaps
Example #3: cannot eliminate space between 2 horizontal divs inside containing div
Their issues seems similar but not identical to mine. In this sample document, the border, padding, outline, etc are set to zero .. yet both Opera and Firefox render a spare pixel at the top of the div. The third may cheat a way around this space but nobody seems to answer why it's there..
Edit: I read MANY articles that are temptingly close to answering this, but they all seem slightly different with the actual issue.
What am I missing? It's my first question so be patient please :)

Is there some CSS3 that will make it all work? This is an experimental project, so the latest CSS3 is welcomed.
PS: I only care about the Opera rendering, though Firefox would be nice to support with the same standards compliant code.. Thanks!
Change the line-height on the div to zero.

Set vertical-align to top on the button. That will fix it.
Right now we have a web page with a bunch of link sections on one page. Each section has a header like so:
This header background is actually two images. The first is just a rectangle and the second has the slanted side on it. As I was looking at this solution, I was wondering if I could solve this with CSS instead of images. While I am not a CSS guru, I did look at a number of examples and was able to get something similar working. However, when I attempt to put text on top of the background, it ends up above the color instead of inside it. The CSS I have also has a fixed size, which is less than idea. I would rather specify a percentage of the available area and have it fill in the color.
Here is the code I've been working with:
<STYLE type="text/css">
.mini_banner
{
display:inline;
border-bottom:30px solid blue;
border-left:0px solid transparent;
border-right:30px solid transparent;
}
</STYLE>
I wanted to apply this to a cell in a table. I also don't want to break compatibility with modern browsers. My "customers" (mostly internal people) are going to be primarily on IE8 or later but I don't want to limit myself if I can help it.
So first, is this possible? Second, how would I accomplish this? And third, is there a way to make it relative in scale instead of fixed?
I would say that you'll have less headaches all the way around if you revert to using a single background image - in this case, a white image with the notch cut out (a PNG-24 with alpha transparency). Make it bigger than you think you need by about 200%, then do something like this:
.minibanner {
background: blue url(..images/notch.png) no-repeat middle right;
font-size: 1.5em;
}
The reason is that relying on border sizes may result in some whackiness across browsers, and it will definitely look weird if any element runs to two lines.
If you make the notch image 200-300% larger, but vertically align it in the middle of the background, and you do increase the font-size, the box will grow, but your white notch will grow right along with it.
UPDATE:
The only other way I can see pulling this off is to add a non-semantic element, such as a or something similar, after your text:
<div>
<p>Hello text</p>
<span></span>
</div>
Then in your CSS:
p {
background: blue;
color: white;
float: left;
padding: 0 20px;
height: 50px;
margin:0;
line-height: 50px;
}
span {
width: 0;
height: 0;
border-top: 50px solid transparent;
border-bottom: 0px solid transparent;
display: inline-block;
border-left: 50px solid blue;
}
See this JSFiddle.
The shape is based on this tutorial on CSS triangles. Now, I've only tried this on a webkit based browser, and it works. You will have to adjust the heights every time you want to change font size, so that is a drawback.
I made it work without an extra span: jsFiddle
.mini_banner
{
width:18em; height:1.5em;
color:white; font-weight:bold; padding-left:0.5em;
margin-bottom:.5em;
}
.mini_banner:before {
display:inline-block; content:''; overflow:hidden;
width:17em; height:0;
margin-bottom:-1.5em; margin-left:-.5em;
border-bottom:1.5em solid blue;
border-right:1.5em solid transparent;
}
Tested in FF, Safari, Opera and IE. (Works in IE8, but not in IE7)
I'm looking for a way to do something which in my opinion should be super simple, but I couldn't figure it out...
I want a graphical element on my web page which is exactly 1 pixel high, 100% wide and has a certain color, let's say red. It should look exactly the same in all browser and should preferably not break the semantics too much.
I don't want to use any images for this and I don't want to use more than one HTML element. Of course, I will not use JavaScript.
I tried the old classic which probably many of you know:
<div class="hr"></div>
<style ...>
.hr {
height: 1px;
background: red;
width: 100%;
font-size: 1px; /* IE 6 */
}
</style>
The problem with the above solution is that IE6 will render this as two or three pixels high, to fit the non-existing contents of the div.
Any ideas?
just do
.hr {
height: 0px;
margin: 0px;
border-bottom: 1px solid #FF0000;
font-size: 1px;
}
I went through the same thing when I was new to CSS.
adding an overflow: hidden; style should fix it also.
I don't have IE6 handy to test, but an actual HR tag can work in modern browsers. Took me a couple of tries to realise you set the background color not the border color:
hr { width:75%; height:1px; background-color:#ebebeb; border:none; margin:1.5em auto; }
(adjust to suit)
I don't have IE6 to test this, but I remember it had to do something with the line height. Have you tried this?
line-height: 1px;
Ok, I had a simple layout problem a week or two ago. Namely sections of a page needed a header:
+---------------------------------------------------------+
| Title Button |
+---------------------------------------------------------+
Pretty simple stuff. Thing is table hatred seems to have taken over in the Web world, which I was reminded of when I asked Why use definition lists (DL,DD,DT) tags for HTML forms instead of tables? Now the general topic of tables vs divs/CSS has previously been discussed, for example:
DIV vs Table; and
Tables instead of DIVs.
So this isn't intended to be a general discussion about CSS vs tables for layout. This is simply the solution to one problem. I tried various solutions to the above using CSS including:
Float right for the button or a div containing the button;
Position relative for the button; and
Position relative+absolute.
None of these solutions were satisfactory for different reasons. For example the relative positioning resulted in a z-index issue where my dropdown menu appeared under the content.
So I ended up going back to:
<style type="text/css">
.group-header { background-color: yellow; width: 100%; }
.group-header td { padding: 8px; }
.group-title { text-align: left; font-weight: bold; }
.group-buttons { text-align: right; }
</style>
<table class="group-header">
<tr>
<td class="group-title">Title</td>
<td class="group-buttons"><input type="button" name="Button"></td>
</tr>
</table>
And it works perfectly. It's simple, as backward compatibile as it gets (that'll work probably even on IE5) and it just works. No messing about with positioning or floats.
So can anyone do the equivalent without tables?
The requirements are:
Backwards compatible: to FF2 and IE6;
Reasonably consistent: across different browsers;
Vertically centered: the button and title are of different heights; and
Flexible: allow reasonably precise control over positioning (padding and/or margin) and styling.
On a side note, I came across a couple of interesting articles today:
Why CSS should not be used for layout; and
Tables vs CSS: CSS Trolls begone
EDIT: Let me elaborate on the float issue. This sort of works:
<html>
<head>
<title>Layout</title>
<style type="text/css">
.group-header, .group-content { width: 500px; margin: 0 auto; }
.group-header { border: 1px solid red; background: yellow; overflow: hidden; }
.group-content { border: 1px solid black; background: #DDD; }
.group-title { float: left; padding: 8px; }
.group-buttons { float: right; padding: 8px; }
</style>
</head>
<body>
<div class="group-header">
<div class="group-title">This is my title</div>
<div class="group-buttons"><input type="button" value="Collapse"></div>
</div>
<div class="group-content">
<p>And it works perfectly. It's simple, as backward compatibile as it gets (that'll work probably even on IE5) and it just works. No messing about with positioning or floats.</p>
<p>So can anyone do the equivalent without tables that is backwards compatible to at least FF2 and IE6?</p>
<p>On a side note, I came across a couple of interesting articles today:</p>

Thanks to Ant P for the overflow: hidden part (still don't get why though). Here's where the problem comes in. Say I want the title and button to be vertically centered. This is problematic because the elements are of different height. Compare this to:
<html>
<head>
<title>Layout</title>
<style type="text/css">
.group-header, .group-content { width: 500px; margin: 0 auto; }
.group-header { border: 1px solid red; background: yellow; overflow: hidden; }
.group-content { border: 1px solid black; background: #DDD; }
.group-header td { vertical-align: middle; }
.group-title { padding: 8px; }
.group-buttons { text-align: right; }
</style>
</head>
<body>
<table class="group-header">
<tr>
<td class="group-title">This is my title</td>
<td class="group-buttons"><input type="button" value="Collapse"></td>
</tr>
</table>
<div class="group-content">
<p>And it works perfectly. It's simple, as backward compatibile as it gets (that'll work probably even on IE5) and it just works. No messing about with positioning or floats.</p>

which works perfectly.
There is nothing wrong with using the tools that are available to you to do the job quickly and correctly.
In this case a table worked perfectly.
I personally would have used a table for this.
I think nested tables should be avoided, things can get messy.
Just float left and right and set to clear both and you're done. No need for tables.
Edit: I know that I got a lot of upvotes for this, and I believed I was right. But there are cases where you simply need to have tables. You can try doing everything with CSS and it will work in modern browsers, but if you wish to support older ones... Not to repeat myself, here the related stack overflow thread and rant on my blog.
Edit2: Since older browsers are not that interesting anymore, I'm using Twitter bootstrap for new projects. It's great for most layout needs and does using CSS.
Float title left, float button right, and (here's the part I never knew until recently) - make the container of them both {overflow:hidden}.
That should avoid the z-index problem, anyway. If it doesn't work, and you really need the IE5 support, go ahead and use the table.
This is kind of a trick question: it looks terribly simple until you get to
Say I want the title and button to be vertically centered.
I want to state for the record that yes, vertical centring is difficult in CSS. When people post, and it seems endless on SO, "can you do X in CSS" the answer is almost always "yes" and their whinging seems unjustified. In this case, yes, that one particular thing is hard.
Someone should just edit the entire question down to "is vertical centring problematic in CSS?".
In pure CSS, a working answer will one day be to just use "display:table-cell". Unfortunately that doesn't work across current A-grade browsers, so for all that you might as well use a table if you just want to achieve the same result anyway. At least you'll be sure it works far enough into the past.
Honestly, just use a table if it's easier. It won't hurt.
If the semantics and accessibility of the table element really matter to you, there is a working draft for making your table non-semantic:
http://www.w3.org/TR/wai-aria/#presentation
I think this requires a special DTD beyond XHTML 1.1, which would just stir up the whole text/html vs application/xml debate, so let's not go there.
So, on to your unresolved CSS problem...
To vertically align two elements on their center: it can be done a few different ways, with some obtuse CSS hackery.
If you can fit within the following constraints, then there is a relatively simple way:
The height of the two elements is fixed.
The height of the container is fixed.
The elements will be narrow enough not to overlap (or can be set to a fixed width).
Then you can use absolute positioning with negative margins:
.group-header { height: 50px; position: relative; }
.group-title, .group-buttons { position: absolute; top: 50%; }
# Assuming the height of .group-title is a known 34px
.group-title { left: 0; margin-top: -17px; }
# Assuming the height of .group-buttons is a known 38px
.group-buttons { right: 0; margin-top: -19px; }
But this is pointless in most situations... If you already know the height of the elements, then you can just use floats and add enough margin to position them as needed.
Here is another method which uses the text baseline to vertically align the two columns as inline blocks. The drawback here is that you need to set fixed widths for the columns to fill out the width from the left edge. Because we need to keep the elements locked to a text baseline, we can't just use float:right for the second column. (Instead, we have to make the first column wide enough to push it over.)
<html>
<head>
<title>Layout</title>
<style type="text/css">
.group-header, .group-content { width: 500px; margin: 0 auto; }
.group-header { border: 1px solid red; background: yellow; }
.valign { display: inline-block; vertical-align: middle; }
.group-content { border: 1px solid black; background: #DDD; }
.group-title { padding: 8px; width: 384px; }
.group-buttons { padding: 8px; width: 84px; text-align: right; }
</style>
<!--[if lt IE 8]>
<style type="text/css">
.valign { display: inline; margin-top: -2px; padding-top: 1px; }
</style>
<![endif]-->
</head>
<body>
<div class="group-header">
<div class="valign">
<div class="group-title">This is my title.</div>
</div><!-- avoid whitespace between these! --><div class="valign">
<div class="group-buttons"><input type="button" value="Collapse"></div>
</div>
</div>
<div class="group-content">
<p>And it works perfectly, but mind the hacks.</p>
</div>
</body>
</html>
The HTML: We add .valign wrappers around each column. (Give them a more "semantic" name if it makes you happier.) These need to be kept without whitespace in between or else text spaces will push them apart. (I know it sucks, but that's what you get for being "pure" with the markup and separating it from the presentation layer... Ha!)
The CSS: We use vertical-align:middle to line up the blocks to the text baseline of the group-header element. The different heights of each block will stay vertically centered and push out the height of their container. The widths of the elements need to be calculated to fit the width. Here, they are 400 and 100, minus their horizontal padding.
The IE fixes: Internet Explorer only displays inline-block for natively-inline elements (e.g. span, not div). But, if we give the div hasLayout and then display it inline, it will behave just like inline-block. The margin adjustment is to fix a 1px gap at the top (try adding background colors to the .group-title to see).
I would recommend not using a table in this instance, because that is not tabular data; it's purely presentational to have the button located at the far right. This is what I'd do to duplicate your table structure (change to a different H# to suit where you are in your site's hierarchy):
<style>
.group-header { background: yellow; zoom: 1; padding: 8px; }
.group-header:after { content: "."; display: block; height: 0; clear: both; visibility: hidden; }
/* set width appropriately to allow room for button */
.group-header h3 { float: left; width: 300px; }
/* set line-height or margins to align with h3 baseline or middle */
.group-header input { float: right; }
</style>
<div class="group-header">
<h3>This is my title</h3>
<input type="button" value="Collapse"/>
</div>
If you want true vertical alignment in the middle (ie, if the text wraps the button is still middle-aligned with respect to both lines of text), then you either need to do a table or work something with position: absolute and margins. You can add position: relative to your drop-down menu (or more likely its parent) in order to pull it into the same ordering level as the buttons, allowing you to bump it above them with z-index, if it comes to that.
Note that you don't need width: 100% on the div because it's a block-level element, and zoom: 1 makes the div behave like it has a clearfix in IE (other browsers pick up the actual clearfix). You also don't need all those extraneous classes if you're targeting things a bit more specifically, although you might need a wrapper div or span on the button to make positioning easier.
Do a double float in a div and use the clearfix. http://www.webtoolkit.info/css-clearfix.html Do you have any padding/margin restrictions?
<div class="clearfix">
<div style="float:left">Title</div>
<input type="button" value="Button" style="float:right" />
</div>
<div class="group-header">
<input type="button" name="Button" value="Button" style="float:right" />
<span>Title</span>
</div>
I've chose to use Flexbox, because it made things so much easier.
You basically need to go to the parent of the children you want to align and add display:box (prefixed of course). To make them sit in the sides, use justify-content. Space between is the right thing when you have elements which need to be aligned to the end, like in this case (see link)...
Then the vertical align issue. Because I made the parent of the two elements, you want to align a Flexbox. It's easy now to use align-items: center.
Then I added the styles you wanted before, removed the float from the title and button in the header and added a padding:
.group-header, .group-content {
width: 500px;
margin: 0 auto;
}
.group-header{
border: 1px solid red;
background: yellow;
overflow: hidden;
display: -webkit-box;
display: -moz-box;
display: box;
display: -webkit-flex;
display: -moz-flex;
display: -ms-flexbox;
display: flex;
-webkit-justify-content: space-between;
-moz-justify-content: space-between;
-ms-justify-content: space-between;
-o-justify-content: space-between;
justify-content: space-between;
webkit-align-items: center;
-moz-align-items: center;
-ms-align-items: center;
-o-align-items: center;
align-items: center;
padding: 8px 0;
}
.group-content{
border: 1px solid black;
background: #DDD;
}
.group-title {
padding-left: 8px;
}
.group-buttons {
padding-right: 8px
}
See Demo
I agree that one should really only use tables for tabular data, for the simple reason that tables don't show until they're finished loading (no matter how fast that is; it's slower that the CSS method). I do, however, feel that this is the simplest and most elegant solution:
<html>
<head>
<title>stack header</title>
<style type="text/css">
#stackheader {
background-color: #666;
color: #FFF;
width: 410px;
height: 50px;
}
#title {
color: #FFF;
float: left;
padding: 15px 0 0 15px;
}
#button {
color: #FFF;
float: right;
padding: 15px 15px 0 0;
}
</style>
</head>
<body>
<div id="stackheader">
<div id="title">Title</div>
<div id="button">Button</div>
</div>
</body>
</html>
The button function and any extra detail can be styled from this basic form. Apologies for the bad tags.
