CSS - Using Css Class To Handle Events

I've read several forums and know that the technique I'm trying to achieve is possible, however I can't seem to get it to work. Basically I'm trying to shift the background positions of both the list item I'm hovering over and the next list item. I'm sure its just a syntax error and not a logic error, anyways the code is below - any help would be greatly appreciated!

Code:

HTML Code

<div class="menu">
    <ul>
        <li><a href="#" class="search"></a></li>
        <li><a href="#" class="battery"></a></li>
        <li><a href="#" class="cart"></a></li>
        <li><a href="#" class="contact"></a></li>
    </ul>
</div>

CSS

.search, .contact, .cart, .battery
{
    width:100px;
    height:30px;
    margin-left:-1px;
    display:block;
}

.search
{
    background-image:url(Images/search.png);
}
.contact
{
    background-image:url(Images/contact.png);
}
.cart
{
    background-image:url(Images/cart.png);
}
.battery
{
    background-image:url(Images/battery.png);
}

ul li a.search:hover
{
    background-position:0px 60px;
}


ul li a.search:hover ul li a[class=battery]
{
    background-position:0px 60px;
}

Sorry for the lousy title, can't come up with better wording....

What I'm trying to say is can someone give me an example code of a css syntax that accept one css classname and add a few more properties to it under a different class name. Sort of like merging two classname into one.

Thanks...

When defining css in a webpage, it can be done using either a class or id. My understanding is that css uses . notation with classes and # notation with id's, regardless of whether the actual css is in the webpage itself of linked externally. Please correct me in error. My css uses classes and external . notation. When I use id's only and # notation exernally, I lose all my styling. Its only when I use the # notation internally that the styling works. In order to use external css I need to declare both a class and id and dot notation. Internally only an id. Is this correct behaviour?

In CSS, which would be more appropriate (or I suppose semantically correct) to use, p.text or .text p ? P representing the <p> tag, and "text" representing the class "text".

Any info or links to pages with info on this matter would be greatly appreciated!

I am new to CSS and confused about when to use id # and when to use class .

Some enlightenment on the benefits/purpose of each would be helpful. I have read several tutorials - but the same pretty much the same to me so I must be missing something

Thanks!

I'm using ASP.NET 2.0 for my site. I already have a CSS that is working for the site; however, because an ASP.NET lable requires CSS Class, how do I convert my current CSS to a CSS Class? I know that a CSS class start with a period then a unique name. The problem is how do I implement the li, ul, a, and so on. Here is what I have that I want to convert to a CSS Class.

#nav {
padding: 0;
clear: both;
}
body.main #nav, body.blogger #nav {
float:right;
width: 220px;
\width: 250px;
w\idth: 220px;
margin: 10px 10px 0 0;
padding: 0;
}
body.second #nav {
float:left;
width: 200px;
\width: 210px;
w\idth: 200px;
padding:0 0 20px;
margin: 0;
}
body.second #nav img {
padding-bottom: 10px;
}
#nav a { color: #006; }
body.second #nav ul {
list-style: none;
padding: 0 0 0 5px;
margin: 0;
}
body.second #nav ul li {
margin: 0 0 7px 0;
font-size: 11px;
}
body.second #nav ul li ul li { margin: 0 0 5px 15px; }
.skip { display:none; }
/* end #nav */

#content p, #nav p {
padding: 0;
margin-top: 0;
margin-bottom: 10px;
line-height: 140%;
}
#content li, #content ol {
margin-top: 0;
line-height: 140%;
}
code, pre { font-family:"Courier New", Courier, mono, monospace; }

/* definition lists, all that and a bag of chips! */
#content dl {
margin:0px;
padding:0;
}
#content dt { font-weight: bold; }
#content dd {
margin-top: 0;
margin-right: 0;
margin-bottom: 10px;
margin-left: 0;
padding: 0 5px 0 0;
}
/* end definition list*/

Any help is appreciated.

Problem solved.

Which is better to use id (#) in CSS or to use class (.) ??

does it affect website rank?

The book i am reading does not clear this up. When would you use class vs id to put elements in different catagories? why not use all id? It seems to make more sense.. ie. make all headers id="header"
and divs also class.

thank you in advance

So I want to create a really simple css file that uses a lot of the same styles. For example I may create a box that takes up two fifths of the page, and is floated left or right, similarly I may have a box that takes up three fifths, or four fifths etc.

The main thing here is that I'm thinking the specifics will be placed inside an ID like so:

Code:

#twoFifths {width:275px; padding: 0px 12px 0px 50px;}
#threeFifths {width:375px; padding: 0px 50px 0px 12px;}

And then to handle the float I'd use a class like so:
Code:

.floatRight{float:right;}
.floatLeft{float:left;}

Is this considered good practice? Obviously as I generate layouts I may want to float either right or left so having an ID for every single thing I may want to use would be a little overwhelming. The problem with this of course is that I can't call an ID twice in a page, and I can't have more than one class... so for example:

Code:

	<div id="templateBlueBox" class="floatRight">
		<h2>Six free lessons</h2>
		<p>These free Lessons are great to read online or print out and carry with you.</p>
					</div>
					
	<div id="templateGreenBox" class="floatRight">
		<h2>New Features</h2>
	        <p>Some fun, helpful study tools to help you get more out of every Lesson. Check them out!</p>
					</div>
				
	<div id="templateOrangeBox" class="floatRight">
		<h2>Sign up for email updates</h2>
		<p>So we can let you know when you can subscribe to get it every week.</p>
	</div>
					
	<div id="templatePinkBox" class="floatleft">
			<h2>Send us feedback</h2>
			<p>Is it the coolest thing ever (or is it just okay)? Tell us what you think!</p>
			</div>
					
	<div id="templateBlueBox" class="floatLeft">
		<h2>Submit photos</h2>
		<p>
		You can be part it..</p>
	</div>

So as you can see I'm having to repeat the id templateBlueBox. Is there a better approach for accomplishing this?

Hi all.

Code from the php file:
PHP Code:
<?php /* If this is a monthly archive */ } elseif (isset($_GET['paged']) && !empty($_GET['paged'])) { ?>
<p class="browsing">You are currently browsing the <a href="<?php echo get_settings('siteurl'); ?>"><?php echo bloginfo('name'); ?></a> weblog archives.</p>
<?php } ?>



Page is at http://www.bartlett-family.net/chri...tt/blog2/?cat=1

You can see on the right where the text is right below the blog search.

Why is the text not formatted to the left?
CSS code:
Code:

.browsing {
	text-align: left;
}

Simple enough. I've put in other CSS attributes just to test. Absurd things like font-family: Arial, Helvetica, Sans-Serif;
& font-size: 8em; just to see if I was missing something small.

Nothing, the class just isn't working. Huh?

Hi there,

In my stylesheet I've written a style for the table tag:

Code:

table {
	width: 500px;
	margin: auto;
	text-align: left;
	border: 1px solid #999999;
	font-family: "Trebuchet MS", "Bitstream Vera Sans", verdana, lucida, arial, helvetica, sans-serif;
	line-height: 140%;
	margin-bottom: 10px;
	padding-bottom: 15px;
	font-size: 14px;
	padding-left: 10px;
}

All the main tables on my site need to be this exact style. I now need to create a table which shouldn't use the table style above. I could have just pasted the stylesheet info directly to the page (and delete the css link at the top of the page), and then delete the table info, but can't do this because the stylesheet link location is dynamic (my new site design will alternate a stylesheet every 24 hours).

Anyone know how I can tell the css to not apply the style to an element?

Thanks,

Hi, I have apage where the div only works on the bottom on the page. I am trying to place it also in the center to divide content. Here is the CSS code:
Code:

.doubleLine{
    clear:both;
    position:relative;
	float:left;
	width:1172px;
	height:6px;
    background-image: url(images/common/double_line.gif);
	background-repeat: no-repeat;
    margin-left:37px;
    margin-right:0px;
    margin-top:6px;
    margin-bottom:6px;
    padding:6px 0px 6px 0px;
}

can anyone tell me why this div with an image won't appear between content? I havetried everything I could think of.

thanks

Hi .. Im still new to all of this (Web and CSS in general) but would like to know if the following is a possiblity... assuming the CSS Below ...

div#item{
width: 200px;
height:100px;
}

div#item_image{
width:50px;
height:100px;
background-image:url(blahblah);
}

div#item_text{
width: 140px;
height:100px;
(...other properties)
}

then when I create an instance of this i use the following HTML

<div id = "item">
<div id = "item_image>
</div>
<div id = "item_text>
</div>
</div>

I know its maybe not the best way to do it .. but im trying to illustrate a point ... each time I create an "item" I am required to redeclare or redefine the child divs ... is there any way I can "embed" (for lack of a better word !) the children so that everytime I create an "item" it automatically creates the "item_image" and "item_text"

so basically .. my HTML will just be

<div id = "item"></div>

and nothing else ??

Thanks for any guidance ...

Thanks for taking the time to read my question.

I can never seem to get this right....

I have this line that I want to affect:

Code:

<li><div class="VACont"><a href="">Edit User</a></div></li>

and I want to be able to edit it with

a:link {}
a:visited {}
a:hover {}
a:active {}

How do I refer to the link with out having to add a class to the <a> tag?

I've tried:
Code:

VACont.a:link {text-decoration: none;}
li.VACont a:link {text-decoration: none;}
a:link li.VACont {text-decoration: none;}

So far no luck.

Thanks,

Brad
