CSS - Syntax Explanation...
Hello I would like to know the difference between:
*name .name #name thanks Similar TutorialsWhat I don't understand about the following code is why the body background color is showing inbetween the divs that mark the header, content, and footer. I want no separation between the divs (margin 0, or so i thought). Can someone explain what's going on? Help very much appreciated. <html> <head> <style> body { background-color: black; } #header { background-color: red; margin: 0; } #content { margin:0; background-color: #ffffff; } #footer { margin: 0; background-color: red; } </style> </head> <body> <div id="header"> <h3>Header</h3> </div> <div id="content"> <p>Content</p> </div> <div id="footer"> <h3>Footer</h3> </div> </body> </html> Hi, I have been trying to get up to speed on the workings of css positioning and have hit a stumbling block very early on. I would like to know what 'normal' means when the w3schools docs say that: (I'd provide a link but this site forbids me to do so) 'A relative positioned element is positioned relative to its normal position.' Could anyone provide a definition or explanation? I'm battling to figure out the basics here. Thanks Jim Hi there, Just playing around with some CSS menu tricks when I came accross this piece of CSS which I don't understand. Code:
#nav li:hover ul ul,
#nav li:hover ul ul ul,
#nav li:hover ul ul ul ul{
display: none;
}
#nav li:hover ul,
#nav li li:hover ul,
#nav li li li:hover ul,
#nav li li li li:hover ul{
display: block;
}
I know that it is being used to display and hide a popup menu, on mouse over. How is this read though? Thanks. Hi, i need a simple, clear and easy to understand explanation of the parameters given to the CSS 'clip' property. i understand what the clip property does in essence - basically clips a rectangle from the given image - but i do not understand how the points given to the rect() function work - i cannot visualise it. My book does not describe it very well and the websites i have visited dont either. Therefore id be grateful if someone could give me a simple explanation 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. I keep getting an error but only when I run the site in IE8: Code: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727) Timestamp: Fri, 13 Mar 2009 16:59:31 UTC Message: Syntax error Line: 1 Char: 25 Code: 0 It keeps pointing to this line of code at the top: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> But if I don't use that the Divs and some CSS seem to break. With or without that code it works great in FireFox. I have no idea what's going on with this. Hi! I need some clarification on what the right arrow meant for the UL and LI Code:
#dmenu li>ul {
top: auto;
left: auto;
}
Thanks... FletchSOD 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. 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 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 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! 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! 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. 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?

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? I'm wondering what's the word is called for setting the image width and height in CSS Code:
img.test
{
<<What's the keyword??>>: 10 px;
}
Thanks, FletchSOD Trying 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;} |
