CSS - Css Mapping And Class

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!

Problem solved.

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?

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.

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

Trying to migrate vbulletin software to xhtml 1.1 using CSS and I have run into a bit of a problem.

It was my understanding that a class can have the same name as another class but behave differently if the parent classes are different.

For example:

table.main .bigWrap .color {
color: blue;
}

Would be different than:

table.sub .bigWrap .color {
color: red;
}

I assumed that .color's parents dictate it's behaviour so main tables and sub tables will display different colors. Is this indeed the case or am I off base?

hi everybody, i have the following problem

my code

Code:

.....
<table>
<colgroup>
<col class="makemebig" />
<col class="text" />
</colgroup>
<tr>
<td>Date:</td>
<td>12.2.12</td>
</tr>

</table>
...

in ie the cols have the right format, but in firefox they have the standard format. what's wrong? i googled but found nothing senseful.

can anybody help me?

i am working for a client that is strict on making sure that all code is up to standards.

the question i have is, how can i use the same class container twice in the same page and have everything up to standards?

the catch is the doctype has to be XHTML 1.0 Transitional and i can't have the same id twice on the page. i'd hate to make 2 classes for the same style.

any suggestions?

Code:

<ul id="headerfooter">
<li><a href="link1.html">header link 1</a></li>
<li><a href="link2.html">header link 2</a></li>
<li><a href="link3.html">header link 3</a></li>
</ul>

Code:

<ul id="headerfooter">
<li><a href="link1.html">footer link 1</a></li>
<li><a href="link2.html">footer link 2</a></li>
<li><a href="link3.html">footer link 3</a></li>
</ul>

hi there

trying to create a overlapping div
but this wouldn't work
Code:

#overlapBar {
	position:absolute;
	width: 250px;
	height: 270px;
	z-index: 2;
	top: 10px;
	left: 600px;
}

but with a layer it does work
Code:

<div id="overlapBar" style="position:absolute; left:600px; top:5px; width:250px; height:270px; z-index:1 ">

I like to have all my css in one file, so how can I overlap and position with <div>

thnks in advance

Hi all,
I am using <tr class="caption"> in order to control the properites of a line in a table. The problem is: this will not work. Nothing that is written in this CSS tag will work

my CSS tag:
Code:

tr.caption {
	font-weight: bold;
	font-size: 14px;
	text-decoration: none;
	background-color: #000000;
	color: #FFFFFF;
                       }

any idea why??

I am greateful for any answer!

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 There,
I am working with an online educational system and working to style it accordingly. The system has "modules" that contain information of various types in their own distinct boxes. I would like to target each heading and style it individually ie different colours etc. I know this is probably a very basic problem and I'm relatively new to the process, but any help would be much appreciated.

Here is the html generated by the system for one of the boxes "module:_148_1"

...............Start HTML Snippet

<div class="portlet clearfix " id="module:_148_1">
<!-- extid:148: --> <h2 class=" ">
<span class="moduleTitle" >What's happening at Ivanhoe</span>
</h2>
<div class="edit_controls">
</div>
<div class="collapsible" style="overflow: auto;">

............................End HTML Snippet

My Current generalised styling on all boxes is achieved via the following css

#moduleTitle,
.portlet h2 {
color: #fff;
padding: 4px 52px 5px 6px;
background: #13770a;
background-image:url(images/headings_details.png);
background-repeat:no-repeat;
background-position:right top;
margin: 0;
font-size:110%;
font-weight:bold;
position:relative;
vertical-align:middle;
overflow:visible;
}

As an example, if I wanted to target this particular module with ID module:_148_1 and set the background colour to #a0012e how would I best achieve this?

Many thanks
Chris

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?

Chris
