Styling horizontal rules - html

Is there a nicer way of styling a <hr /> tag using CSS, that is cross-browser consistent and doesn't involve wrapping a div around it? I'm struggling to find one.
The best way I have found, is as follows:
CSS
.hr {
height:20px;
background: #fff url(nice-image.gif) no-repeat scroll center;
}
hr {
display:none;
}
HTML
<div class="hr"><hr /></div>

The classic way of doing this is creating a wrapper around the <hr> and styling that. But I have come up a CSS trick for image replacing the element without the need for extra markup:
For non MSIE browsers:
hr {
border : 0;
height : 15px;
background : url(hr.gif) 0 0 no-repeat;
margin : 1em 0;
}
Additionally for MSIE:
hr {
display : list-item;
list-style : url(hr.gif) inside;
filter : alpha(opacity=0);
width : 0;
}
See entry on my blog for further info and an example of the trick in action.

If you set display to block it should behave more like a <div>.
Your answer you should remove hr altogether and just use the div

You could apply the background image to the bottom of the preceding element, perhaps with a bit of extra padding. That way you can get rid of any surplus / non-semantic markup.

this is my css i am writing a page for a client and due to some relative positioning it makes me a problem with a background as u see here the white line after the HR line.
Thanks everyone who responds.
Edit:
Wondered how to update this answer, as there is a lot to talk about found it best to take it from bottom up. This will bring you to a layout like this:
Stage one demo.
The menu and logo should stay in place when you re-size the window etc.
Had a look at your code now. It is better, but you still have some trouble:
border is still set on image. Invalid markup.
repeat-xy is still used on background. Invalid property value.
#content still has padding without units. Invalid property value.
<br> tags are still used to make paragraphs in text.
There is an extra } after #content. Invalidates CSS file.
Number 4. should be fixed, but not that important right now.
As we already have discussed 1-3 it is hard to understand why you keep them. Invalid markup and styling makes for unreliable result.
It can look OK in one browser, in one version of one browser, look whack in another, and totally break in a third. You get misinformation between code and result. When or if you fix it to be valid other unexpected things may change and you have to do a lot more work to clean it up. As a whole and rule number one. No matter how wrong markup and styling might be seen from a how to do it perspective one have to keep invalid markup and style out of it.
To validate your work, and as you are where you are in regards to experience, do it all the time. Do small changes: validate. Do small changes: validate. And so on. Use:
For HTML
For CSS
Markup
The markup as it is now is not the easiest to style or get to behave good in a dynamic way. hr's is not the easiest to work with and vary between browsers. Do not use tables for menu's or styling. They are best left for what they are intended to: show tabular data. For your menu you can ask yourself: what is the menu; well, it is a list. A list of options for end-user to navigate trough the site. There is a lot of examples on the web using lists as menus. Search the web for CSS list menu etc. You can create nice looking, cross-browser reliable CSS only, (no JavaScript dependency), menus.
But let us start with the basic markup: You will usually find it good to wrap the whole page inside a wrapper. Then add sub-items into that. To position elements like your main menu, logo etc. it could be good to use a wrapper for each and position them by float, margins etc.
In general use margins and padding.
Page layout
               Head                  Div
              Divider                Div
            Content                 Div
             Footer                  Div

      LOGOmenu                 
Styling + markup
To make it easy for yourself use temporary borders and background colors to view how the various elements float around. Also use the browsers built-in tools to show various things like margins etc. This is invaluable.
Only remember that if you use borders, and you intend to remove them on finished product, they can take up space.
As an example you could have something like this:
Strong colored first attempt.
HTML:
<div id="wrap">
<div id="head">
<div id="logo">
<a href="index.php">
<img id="logo_img" src="http://cupido.g6.cz/pictures/header.png" alt="EWITA" />
</a>
</div>
<div id="menubar">MENU</div>
</div>
</div>
CSS:
* {
margin : 0;
padding : 0;
}
body {
font-family: Arial;
height : 100%;
background : orange;
}
#wrap {
position : relative;
background : pink;
width : 100%;
height : 100%;
}
#head {
position : relative;
width : 800px;
height : 131px;
margin : 100px auto 0 auto;
background : blue;
}
#logo {
position : relative;
width : 431px;
float : left;
background : red ;
}
#logo_img {
width : 439px;
height : 131px;
float : left;
}
#menubar {
position : relative;
background : #fff;
width : 300px;
float : left;
margin-top : 107px;
padding : 3px 0 3px 10px;
}
Note: I use a hard reset of margin and padding on all elements by:
* {
margin : 0;
padding; 0;
}
And then set margins and padding on tags and elements as I use them. Often find this to be a much easier way then the other way around. Remember that things like body also has padding etc. and often can result in undesired spacing.
This way you also get rid of the horizontal scroll-bar at bottom.
By using float on thing like logo and menubar the elements align nicely.
Next we can add the divider. Here we could use a div and set border for top and bottom. On content we use padding to make space between header, text and footer. We also add white border to top of content that aligns nicely with the divider.
Added divider, content and footer.
HTML:
<div id="divider"></div>
<div id="main_content">
MAIN CONTENT
</div>
<div id="footer">
FOOTER
</div>
CSS:
#divider {
border-top : 5px solid #353535;
border-bottom: 3px solid #888;
}
#main_content {
position : relative;
background : url('http://cupido.g6.cz/pictures/background.png');
border-top : 2px solid #fff;
padding : 120px 0 130px 0;
}
Next we can add the content text and style it. Also added style to footer.
With content and styled footer.
HTML
<div class="content_text">
<p>
text text text ...
</p>
</div>
CSS:
.content_text {
margin : 0 auto;
width : 700px;
background : #fff;
border : 1px solid;
padding : 50px 30px;
}
.content_text p {
font-size : 16px;
}
Resize window etc. and see it floats nicely around.
Now it is time to add the menu. As mentioned earlier we can use list for the menu. It is much more suited for the task then a table. In that regard also note that a menu might have sub items, as such a list becomes the only sane option.
Also note on the menu: You likely do not want to style visited links with other color. But that is up to you of course.
With added menu and some re-styling on background colors etc.
HTML:
<ul>
<li><a class="menu" href="smaler.php">úvodní stránka</a></li>
<li><a class="menu" href="sluzby.php">služby</a></li>
<li><a class="menu" href="kontakt.php">kontakt</a> </li>
</ul>
CSS:
As we already have set margins and padding to 0 on all elements this is trivial:
#menubar ul {
list-style : none;
}
#menubar li {
padding : 0 10px;
float : left;
}
a.menu {
text-decoration : none;
color : #fff;
}
a.menu:hover,
a.menu:active {
color : #3cc8a8;
}
Remove helping colors etc. and we have a version 0.1 ready for further testing and expansion.

Original answer:
There is more then one problem. Firstly the markup:
XHTML
<link rel="icon" type="image/png" href="./pictures/favicon.png">
Should be:
<link rel="icon" type="image/png" href="./pictures/favicon.png" />
<link rel="stylesheet" type="text/css" href="style.css">
Should be:
<link rel="stylesheet" type="text/css" href="style.css" />
<img src="./pictures/header.png" width="439" height="131" border="0" alt="">
Should be XHTML 1.0 Strict img tag does not have a border attribute, and need
to be closed:
<img src="./pictures/header.png" width="439" height="131" alt="" />
<hr class="main" /></hr>
Should be:
<hr class="main" />
Use paragraphs to group text, not:
Text<br/><br/>Text<br/><br/>Text ...
but:
<p>Text</p><p>Text</p><p>Text... </p>
CSS
Inline comments are not valid, use:
/* some comment */
Not:
// some comment
You are missing unit on most of your padding values. If a value is non-zero it needs a unit such as pt, px etc. Use:
padding: 5px 0 0 20px;
/* Not: */
padding: 5 0 0 20;
If you do not, it has no/(should not have any) effect.
background-repeat does not have repeat-xy. Use:
background-repeat: repeat;
/* not */
background-repeat: repeat-xy;
or nothing at all, as that is the default.
Fix those first. Then set some color to your things so that it is easier to understand what you want. You can change them back later. Use red, blue etc.
Example.
Regarding zero width no break space bug, as displayed in Vim:
Try adding this CSS:
CSS:
#wrapper {
margin: auto;
min-height: 500px;
background-image: URL('../images/squared_metal.png');
background-repeat: repeat-xy;
z-index: 10;
padding-top:10px;
margin-top:-30px;
}
#content {
margin:auto;
width:700px;
background-color:#ffffff;
margin-top: 10px;
border:1px solid;
padding: 50 30 50 30;
}
I totally overlooked the 'padding-top' css property originally. Thank you all for providing that information!
Please update your site with this CSS and let me know if it works! Since I tested this on my own machine, you should change back the background-url to your custom .png file.

space between top of browser or frame and document body

I have a page with a image. I want set it top of page.
<HTML>
<HEAD>
<title></title>
<style>
html, body {
margin: 0;
padding: 0;
}
</style>
</HEAD>
<BODY style="background-color:#3baa35;" >
<IMG border=0 src="home.PNG" ></p>
</BODY>
</HTML>
But there is one line of space between the top of the page and the body.
How to set image top of page?
Put some styles:
p { margin: 0; padding: 0; }
This is because each browser has its own default CSS values. You can use Eric Meyer's reset CSS to have the same display on all the browsers :)
Link to Reset CSS
Don't forget to put border: none; as well
IMO, your css properties are okay .
as
Margin is on the outside of block elements
We use padding for inside of block elements .
By default, images align their bottom edges with the baseline of the text.
just use to get rid from this
img { /* Or a suitable class, etc. */
vertical-align: bottom;
}
Hope it will help.
Here is a hack to your answer.
Your p tag inherits the font-size from the a tag and thus assigns the margin to a size of 1em which is the size of the letter M of the parent elemt i.e THE a tag
So if you set the font-size of a to 0 then the font-size of p will be 0 and hence the margin too.
Sounds pretty cool right? Here's a working fiddle...
FIDDLE
a{
font-size:0pt;
}

2 background images in one div/table?

I am trying to design a layout for my forum that has 2 background images on a div or a table. I got the idea after looking at this forum's design (http://s4.zetaboards.com/APTSecretServices/index/) If you see on the main category labeled "Category" it contains 2 background images. From exploring the CSS (http://s4.zetaboards.com/c/35079/404/css.css) I found out it was labeled h2left and h2right.
Code:
.h2left {
background: url(http://z4.ifrm.com/30294/164/0/p1083155/h2left.png) no-repeat;
}
.h2right {
background: url(http://z4.ifrm.com/30294/164/0/p1083156/h2right.png) no-repeat right
top;
height: 40px;
}
After seeing this I realized they used the h2, and then on the forum they combine it all together somehow It appears to be done by this code
<table class="cat_head"><tr><td>
<h2>
Category
</h2>
</td></tr></table>
Which is very confusing considering I can't find any proof on how they combined the two.
If you don'y have to support IE<8 than the clean solution is to use pseudo-selectors :before and :after. They really contain unleashed power!
Check the browser support: http://caniuse.com/css-gencontent
In the case of IE6, IE7 the user get only background declared on 'real' DOM element.
Remember that pseudo elements :before and :after cannot be used on empty elements (like images) - because there are 'injected' into element before first (:before) and last (:after) node. Remember that you have to include 'content' declaration inside :after and :before to display the declared styles, too.
On more complicated layouts you can get very nice effects by using "position: absolute" and "z-index" (1.stacking context will prevent layers overlapping by complicated layouts, 2. for IE8 z-index by pseudo-elements don't work, so layers are displayed in the same order as rendered in DOM)
More about pseudo element is nice explained there:
http://www.hongkiat.com/blog/pseudo-element-before-after/
So, conclusion:
<tr>
<td>
<h2 class="table-header">Some text</h2>
</td>
</tr>
.table-header {
/* EDITED: didn't put position on affected element, first that makes the coordinates of :after elements to be calculated from the right element. Sorry! */
position: relative;
/* if element is h2 than we got already "display: block" => width: 100%, height:auto */
font-size:1.5em;
line-height:2.5em; /* that centers the text if it is only one line long. For multi-lined text that method is not reasonable. I took arbitrary height bigger than font-size */
background: url(img-main.jpg);
}
.table-header:after {
content: '';
position: absolute;
top:0; right: 0; bottom: 0; left:0;
background: url(img-additional.jpg);
background-repeat: no-repeat;
background-position: center right;
}
Hope that helps
The markup on that website is
<div class="h2wrap">
<div class="h2left">
<div class="h2right">
<div class="h2center">
</div>
</div>
</div>
</div>
so its a div within a div
You can use this css for multiple background images
#bg_table {
background: url(http://z4.ifrm.com/30294/164/0/p1083155/h2left.png), url(http://z4.ifrm.com/30294/164/0/p1083156/h2right.png);
background-position: left center, right center;
background-repeat: no-repeat;
}

How to remove excess space added with \n

How can I remove the space between the <fieldset>'s in the following example? Here's a JSFiddle.
HTML
<!-- Displays bad, but HTML looks good -->
<fieldset>test</fieldset>
<fieldset>test</fieldset>
<!-- Displays good, but HTML looks bad -->
<fieldset>test</fieldset><fieldset>test</fieldset>
CSS
*
{
margin: 0;
padding: 0;
}
fieldset
{
background-color: red;
display: inline-block;
}
I'd like to be able to leave space between the <fieldset>'s in the HTML code, since their contents are quite long. But I need them to display right next to eachother.
The best solution is to remove any spaces between inline-block (or inline) tags.
You can use comments for better readability:
<fieldset>test</fieldset><!--
--><fieldset>test</fieldset>
There is no CSS solution which can be 100% reliable.
EDIT: it doesn't seem it's the case but some template engines provide this behaviour, like twig's spaceless
Demo
How about float: left;:
CSS:
fieldset {
background-color: red;
float: left;
}
A different solution is to put the fieldsets in a DIV container and set the font-size to 0 using CSS for that container. Then, of course, set the font-size of the field-sets back to whatever you need it to.
Setting the font-size to 0 on parent container basically removes the white-space between inline-block elements of that container.

CSS puzzle: How to add background-image and set height/width on empty span?

I've set background-image on a couple of span elements, but they aren't showing up, I think because my height and width settings are being ignored.
HTML source:
<div class="textwidget">
<span id="starthere" class="sidebar-poster"></span>
<span id="#primarydocs" class="sidebar-poster"></span>
<span id="donate" class="sidebar-poster"></span>
</div>
CSS:
span.sidebar-poster {
margin-bottom: 10px;
background-repeat: no-repeat;
width: 160px;
}
span#starthere {
background-image: url(/betatesting/wp-content/themes/dynamik/css/images/brunelwantsyou180.jpg);
height: 285px;
}
span#starthere:hover {
background-image: url(/betatesting/wp-content/themes/dynamik/css/images/brunelwantsyou_hover.jpg);
}
span#primarydocs {
background-image: url(/betatesting/wp-content/themes/dynamik/css/images/brunelwantsyou180.jpg);
height: 285px;
}
span#primarydocs:hover {
background-image: url(/betatesting/wp-content/themes/dynamik/css/images/brunelwantsyou_hover.jpg);
}
span#donate {
background-image: url(/betatesting/wp-content/themes/dynamik/css/images/donatebutton.jpg);
height: 285px;
}
span#donate:hover {
background-image: url(/betatesting/wp-content/themes/dynamik/css/images/donateposter_hover.jpg);
}
None of the background images are actually visible.
In Chrome Developer Tools, Under Computed Style, these two spans do appear to have a background image. If I copy and paste the URL of this image, I see the image. Yet nothing is actually rendering.
[UPDATE - this part is solved, thanks] In Chrome Developer Tools, under Matched Rules, only the #starthere and #donate spans are actually picking up the background-image attribute. The #primarydocs span is not. Why not?
SPAN is an inline element. Which will indeed ignore such things. Try setting the display mode in your CSS to something like: display: block;
I think your spans need to have display:inline-block, an ordinary span will always have its 'natural' width and height.
Since a is display: inline; automatically it cannot take width and height attributes from CSS.
If you want to use the inline characteristic but without inner content (ie: <span>content</span>) and instead have a background image, use padding instead.
ie:
span {
padding: 10px;
}
but input the number of pixels you would need to show the image.
Solved it - you can't set height and width on span because it is an inline element. Switching to div solved it.
Phew.
If anyone knows how to debug CSS with better tools than guesswork, hope, Google searches and swearing, please let me know!
