CSS - Class And Id Syntax Question
I have searched but can't find a clear answer to what I suspect this is a noob question.
please correct me if I am wrong. element#id ({} - applies to the element with id #id element {} - applies to all element that are in the block #id element.class {} - applies to all element with .class but what is .class element {} ? tia, Rand I went back to the Definitive Guide and found this covered in section 2.5.2. Descendant Selectors Similar TutorialsTrying to create a table psuedo class so that the specific attributes apply to the target table. Not sure if my syntax is correct. What I would like is to call the ID DataTable and have it cascade thru the tr, td...... Here are my tags: #DataTable { width:auto; border-collapse: collapse; border:1px solid #cccccc; border-spacing :20px;} #DataTable tr { border-spacing:20px;} #DataTable td.headerDescription{ width: 240px;} #DataTable td.fundCell { width: 240px; text-indent:40px;} #DataTable td.percentageCell { width: 60px; vertical-align:middle; text-align:center; border-right:1px solid #cccccc;} #DataTable td.seperator { border-top:1px solid #cccccc;} #DataTable td.assetCategory { width: 240px; text-indent:20px; vertical-align:middle;} #DataTable td.headerColumn { font-weight:bold ; width:40px; background-color:#F0F0F0 ; text-align :center;} #DataTable td.leftHeaderColumn { font-weight :bold ; width:40px; background-color:#E0E0E0 ; text-align :center ; border-left:1px solid #cccccc;} #DataTable td.assetClass { width: 240px; vertical-align:middle; font-weight :bold;} #DataTable td.performanceCell { width:60px; background-color:#E0E0E0 ; text-align :center ; vertical-align :middle;} Ok, so I've done the w3schools.com tutorial on CSS and I still have some basic syntax questions. In my wordpress style.css I see the following entry: #featured-top .featuredpost img { background: #FFFFFF; margin: 0 0 5px 0; padding: 4px; border: 1px solid #DDDDDD; } Does this mean that these rules apply only to elements in this specific order? Like, in English, "rule applies to an img, that has a parent in the class featuredpost, that has a parent with id = featured-top"? If so, does the featuredpost class have to be defined previously or is this considered the definition? Second question, in the HTML I see this syntax: <div id="wpsb" class="widget wpsb_opt_in"> I didn't think you could have spaces in a class name. Or does this mean that wpsb is in 2 classes? When I search style.css I don't see the "wbsb_opt_in" class anywhere. Thanks Why doesn't the class applied to the span tag do anything? Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title></title>
<style>
body {
font-family: Georgia, Times, serif;
font-size: 12pt;
}
#main p {
padding:0 10px;
}
.newssubhead {
font-size: 124%;
color:red;
}
</style>
</head>
<body>
<div id="header">
<p>
<span class="newssubhead">Test test test test test test test test test test test test </span>
<br>
Something else...
</p>
</div>
</body>
</html>
Really basic question. I've created a CSS text class. How do I reference it to apply to a text sample? I've been using this page as my guide: http://www.htmlgoodies.com/beyond/css/article.php/3470231 But they only reference commands such as <I class="name"> and <U class="name">. I don't want to add any Italics or Underlines, so how do I only reference the class? hey, I got a table, every <td> in the table got the css class .regular. (<td class='regular'>). When the user moves their mouse over a row, that row should change color. This works with the following code: <tr onmouseover='this.className=\"hoverRow\"'> However, this only works if the td's in that row have no class set yet. And since all td's in my table have a class set allready, i cant use this. How can i overwrite the class of the td's by the class for the whole row? thanks in advance Using the following example: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
<style type="text/css">
a
{
display: block;
}
a.one.on, a:hover.one, a:hover.one.on
{
color: red;
}
a.two.on, a:hover.two, a:hover.two.on
{
color: orange;
}
a.three.on, a:hover.three, a:hover.three.on
{
color: green;
}
</style>
</head>
<body>
<a href="#" class="one">one</a>
<a href="#" class="two">two</a>
<a href="#" class="three">three</a>
<p> </p>
<a href="#" class="one on">one</a>
<a href="#" class="two on">two</a>
<a href="#" class="three on">three</a>
</body>
</html>
Notice how, in IE6 (works fine in FF), when the secondary style named 'on' is added, all 3 links in the 2nd set display the properties of the style: Code: a.three.on, a:hover.three, a:hover.three.on
{
color: green;
}
(since it is last in the list) rather than the style specified by their respective numbers (i.e. 'one', 'two' or 'three'). Is there a way to overcome this in IE. 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... Hi guys, I have this: Code: <li style='background-image:url(../images/layout/listitem.png); background-position:0px " . $background . "px; height:23px; background-repeat:no-repeat;'> I want a hover effect, I found a w3c article 'http://www.w3.org/TR/css-style-attr' But copying the syntax just does not work? Any help? Hey everyone, the admins have implemented a new hack to the forums, allowing you to post your code with nicely coloured text rather than just the normal black or the old php stuff.

As you can see from the thread I linked, there are many many other languages supported, but these three examples are more likely to be used than any other in this particular forum... Have fun with it, and please do use this feature, I'm sure it will make things much easier for us to read/understand, rather than just posting chunks of code. Enjoy! --Jon.

Thanks... FletchSOD Hello I would like to know the difference between: *name .name #name thanks Hello! I have been teaching myself the ins & outs of CSS for presentation & there is something I'm not exactly clear about "selectors, classes, ids, rules & definitions, delimiters" and the like. Sometimes I notice people are creating rules for elements or classes that look very different...I think this has to do with parent elements or selectors/properties, but I am not sure. Here's a few examples of rules that I don't understand: Code: div#navigation #navigation .navigation a .body div#navigation > a I know how to define a rule & class, for example #navbar to set the properties such as text color, background, etc. even a background image for this DIV. What I'm trying to say is "What the heck is the difference between using a Hash mark (#) versus a period (.) and when the heck did > or < come into play?" No tutorials on learning CSS seemed to actually explain these, just tell you "that's how it is," so I am very curious to learn more. Thanks for your help! Hi all, What does this mean? H1 A:link { color:#fff } - or - .sectionhead H2 { font-size: 12px; } I'm asking specifically about the space between the name of the selector and the HTML tag reference. What function does that space have? If it were a comma I would know, but I don't know what a space means. Sorry if totally dumb question. Also, I keep seeing three-character hex values (e.g., #fff, #0cd, #078, etc). How are they used, what do they mean? I would have thought it meant to repeat the three characters to make the six (eg, #ffffff, #0cd0cd, #078078) but that appears not to be the case. I've been looking around w3schools.org to find answers to questions like these, but no luck. Any suggestions? Thanks to anybody who takes the time to answer! Laura S. Hello. I'm playing around with CSS and trying to learn it, but for some reason, I can't figure out why my code won't work. It's very simple, the site, and all I want to do right now is pub a small black border around my first DIV, "header-left" just for the heck of it. Code:
<HTML>
<HEAD>
<TITLE>Andy/s</TITLE>
<!--Style Sheet-->
<STYLE type=text/css>
header-left
{
border:1em solid;
}
</STYLE>
</HEAD>
<BODY>
<DIV ID="header-left">Hi</DIV>
</BODY>
</HTML>
I think it should work. I've tried em and px for the border and FireFox is still showing nothing. Any help? I'm open to anything! How to define a style so that I can just put <table class="abc"> and it will apply to both table, th, td together? currently i am using: table,th,td{ //style here } it work in all table, th, td. But i just sometimes want to write <table class="abc"> and it would apply in all cell within this table. so that I don't need to write <th class="abc"> , <td class="abc"> in every tag in same table. thx. Greetings all, Firstly, I am just now starting to use CSS instead of tabled layouts. I must say I am impressed by the power of CSS, but am still learning the ins-and-outs of it. I was wondering if there are any good references/books you'd suggest purchasing or looking at online? Now for my specific question. For my simple page project I am using to learn CSS, I have a <div> that denotes the header. This is supposed to simply have a small .jpg image on the left and some text on the right, like this: ___________________________ |[ i m a g e ]....................text | However, it comes out looking like this: ___________________________ |[ i m a g e ]..........................| |.....................................text| I suspect it is due to the align: right of the text, but am not sure how to correct it. Relevant snippets of code: testpage.html Code: ... <div class=header> <img src="image.jpg"><h1>TEXT</h1> </div> ... style.css Code:
...
#header{
background-color: #FFF;
border: 2px solid #666666;
width: 860px;
margin-left: auto;
margin-right: auto;
margin-top: 30px;
margin-bottom: 0;
}
#header h1{
text-align: right;
margin-right: 20px;
font-style: italic;
letter-spacing: 3px;
}
Thanks for any advice. I was looking over the www.csszengarden.com page and the way CSS was used there, but now I'm puzzled about the way the p element & p class is used in that document. In the stylesheet, the p element is specified but then in the html code, this type of code is used: <p class="p1"> <p class="p2"> <p class="p3"> For each new paragraph the class p is incremented by 1. However, the classes p1, p2, p3 etc. are not specified anywhere in the stylesheet. Is it a correct use of CSS & html code, or are the 'missing' classes perhaps an omission? Can anybody explain to me how this affects those paragraphs? Hi, I'm trying to use CSS and php includes to simplify my website admin. What I'm trying to do is create a banner area, a left column and a right column. Each section then calls another php page. I will eventually let the right column have the correct content instead of calling another page. My problem is that none of the basic formatting is being applied to my content. The menu.htm page in bold is also calling the style.css as is the c_index.php. I have tried seperating the layout CSS and the formating CSS but it did not make a difference. When I view both menu.htm and c_index.php in seperate windows they are affected by changes in the style.css! Would somebody be kind enough to explain where the error is?
