CSS - Multi-class Css, Good Or Bad Practice?
I saw the use of multiple classes in one "class" attribute at a contract I was on, I wanted to know how DevShed people felt about this practice.
Basic Example: css Code: Original - css Code .redFont { color: red; } .blackBack { background-color: black; }
.redFont {
html Code: Original - html Code <pre class="redFont blackBack">test</pre> <pre class="redFont blackBack">test</pre> Seems to work with javascript in Firefox and IE, anyway.. javascript Code: Original - javascript Code element.className = 'redFont blackBack'; element.className = 'redFont blackBack'; Similar TutorialsI'm just pondering over the performance differences between having a flexible css sheet which requires the html to call several classes for the desired effect, against having each element specifically styled and therefore having code repetition... ie; CSS: Code: .emphasise{
color:#ed5200;
}
.txt_bold{
font-weight:bold;
}
.txt_big{
font-size:2em;
}
HTML: Code: <div class="emphasise txt_bold txt_big">Hi there!</div> <div class="txt_big">I'm not as bold</div> ----- or this method ----- CSS: Code: .title{
color:#ed5200;
font-size:2em;
font-weight:bold;
}
.sub-heading{
font-size:2em;
}
HTML: Code: <div class="title">Hi there!</div> <div class="sub-heading">I'm not as bold</div> Does anyone have any idea what could be happening to my main menu - it dissappears in Safari! Hobo hello. I am currently using a simple horizontal top menu with a vertical drop down. I would like to change the vertical drop down to be horizontal, multi column, and should accomodate more than one line, if possible. The example I'm going for is used as top navigation he nfl - baltimore ravens home page and he ge home page Here is the code I'm using currently (would like it to be all CSS). #### ul#mainNavigation { padding-left:185px; } ul#mainNavigation li { padding:0 16px; float: left; display:inline; position: relative; list-style: none; color:White; _width:1px; } ul#mainNavigation li.Seperator { padding:0px; _width:1px; } ul#mainNavigation li.over { background-color:white; } ul#mainNavigation li.over a { color:Red; } ul#mainNavigation li a { color:White; text-transform:uppercase; text-decoration:none; font-weight:bold; display:block; } ul#mainNavigation a:hover { color: Red; } ul#mainNavigation li a { display: block; } ul#mainNavigation li p { height:19px; } ul#mainNavigation li ul { display: none; position: absolute; background-color:Black; opacity:.8; filter: alpha(opacity=80); -moz-opacity: 0.8; margin-left:-16px; } ul#mainNavigation li.over ul { display: block; z-index:999; } ul#mainNavigation li.over ul li { float: none; background:none; border:none; white-space:nowrap; padding:0px; } ul#mainNavigation li.over ul li a { color: white; padding:5px; border-bottom:solid 1px black; } ul#mainNavigation li.over ul li a:hover { background: #3d1f6e; color: white; } ~~~~~~~ HTML ~~~~~~~~~~~~~~ <ul id="mainNavigation"> <li> <p><a href="Mainlink1.html">Mainlink1</a></p> <ul> <li><a href="link2.html">LINK 2</a></li> <li><a href="link3.html">LINK 3</a></li> <li><a href="link4.html">LINK 4</a></li> <li><a href="link5.html">LINK 5</a></li> <li><a href="link6.html">LINK 6</a></li> <li><a href="link7.html">LINK 7</a></li> </ul> </li> <li> <p><a href="Mainlink2.html">Mainlink2</a></p> <ul> <li><a href="link2.html">LINK 2</a></li> <li><a href="link3.html">LINK 3</a></li> <li><a href="link4.html">LINK 4</a></li> <li><a href="link5.html">LINK 5</a></li> <li><a href="link6.html">LINK 6</a></li> <li><a href="link7.html">LINK 7</a></li> </ul> </li> </ul> #### Thank you, in advance! ~ lahddah What do you guys think....just a template I made for practice http://csstest.dmsbdesign.com/templates/templates%201/ heres the color scheme I used too incase you guys have any suggestions http://colorschemedesigner.com/export/ Hi team, Ok, so I'm biting the web2.0* buzzword bullet, and decided I want a tag cloud & I'm wondering what's the best (standards compliant, portable, etc ) way to handle this in css? The main issue I'm having is how to handle the random positioning of the tags in the cloud? Any ideas on the semantics of these tags - are disconnected href's ok, or should I be wrapping them in p's or something? Another question - is there a more elegant way of handling different sizes without having one style for each size? Cheers all, Simon (* ) Hi Everyone, I'm currently building a site for a client that has a 3 column layout and horizontal footer at the bottom of the page. The client has requested the navigation column (which is running down as the far left column, (I have attached an image for clarification) has a background-color that runs down the full length of the page, from the top of the browser window until it meets the footer at the bottom of the page. The footer needs to do the same, but expand horizontally so it stretches from the left of the browser window to the right. Additionally, if the user is on a larger screen size that creates more vertical space at the bottom of the browser window, the background-color of the footer needs to stretch down to meet the bottom of the browser window. Currently, the website is set up so the 3 columns (including the navigation) is housed in a div tag with relative positioning, auto margins for centering and 960px width. The site is currently in offline development so I unfortunately won't be able to share it with you at this stage. However, please see the attached image for clarification. What I'm after is opinions on a best practice to achieve this. I have tried setting the navigation height to 100% and footer width to 100%, however it's producing undesirable results. Any help would be greatly appreciated! Please let me know if you would like further descriptions. The image can be found he www . harrycourt . com /temp-images/layoutimage01.png Edit: I forgot to mention an important point. I would prefer if this can be achieved while keeping the height of the main wrap container as auto, as opposed to a pixel value. Thanks, Harry Hi I wanted to see what some of you folks do with web files as a "best practice" for testing. I try to be as economical as possible with my css, but sometimes it seems like i have way too many styles going. Anyway, I usually go to the W3C validator and test my files here first. (especially if i am doing standards strict) http://validator.w3.org/ Then I usually run it through HTML tidy to make sure i haven't made any mistakes. Does anyone have any better ideas for checking to be sure you are doing things the best way? Or a better web production file release protocol? Thanks in advance! Shana Is it more common practice to place all div's within one div as seen he Or to have all div's independent, as shown he I heard people complaining about "accessibility", so i finally designed a site with relative font sizes. my default font sizes are 90% of whatever the browser default would be. to my horror, i see that indented lists that contain indented lists get progressively smaller.... can someone suggest how to prevent this while still letting allowing variable font sizes? many thanks. dan I've seen where the "primary" font and size are set in the body tag, and in various sub-tags, the size and other characteristics such as line height and color are then set. As to size, in the case I describe, I've seen it expressed as a percentage. Is this how it's done, "best practice"? I've seen it on a number of high-profile sites, specifically the NYT site. Example: Code:
body {
font-family: Georgia, Times, serif;
font-size: 12pt;
}
#main {
font-size: 80%;
color: #330;
line-height: 1.5em;
}
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;
}
I was wondering what is the best practice for aligning elements on same "line"? for example, say I have a header of the site with logo on left most side and on the right side I want to have right-aligned text with a link of a variable width, how would I achieve this? Do I need 2 separate divs that float left and have set width? Example: I've mucked up my css a bit. Works great in IE but not in FireFox. Submenus are not under their main menu item. and I can't seem to get it centered. Here is the site. Causeway Lighitng And here is the css (it the nav2 portion that controls the top menu) Code: #nav, #nav ul {
margin: auto; /* centres the nav */
padding: 0;
list-style: none; /* removes the bullets */
width: 100%;
}
#nav2, #nav2 ul {
margin: auto; /* centres the nav */
padding: 0;
list-style: none; /* removes the bullets */
width: 135px;
}
#nav li, #nav {
margin:0;
padding:0;
}
#nav2 li, #nav2 {
margin:auto;
padding:0;
}
#nav ul li {
position: relative;
width:130px;
line-height:14px;
padding:0;
margin:0;
}
#nav li ul {
position: absolute;
margin-left:134px;
margin-top:-24px;
display: none;
}
#nav li ul li {
position:relative;
float:none; /* stops the submenus from being horizontal */
}
/* Styles for Menu Items */
#nav li a {
display: block;
text-decoration: none; /* removes the underline */
color: #777;
background: #fff; /* necessary to fix an IE6 Bug */
padding: 0px;
border: 1px solid #ccc;
}
#nav2 li a {
display: block;
text-decoration: none;
/* removes the underline */
color: #777;
background: #FFCC00;
/* necessary to fix an IE6 Bug */
padding: 0px;
border: 1px solid #ccc;
text-align : center;
}
/* Fix IE. Hide from IE Mac \*/
* html #nav li, * html #nav2 li { float: left; height: 1%; }
* html #nav li a, * html #nav2 li a {
height: 1%;
margin-left : auto;
}
/* End */
#nav li a:hover, #nav2 li a:hover { color: #E2144A; background: #f9f9f9; } /* Hover Styles */
#nav li ul li a, #nav2 li ul li a { padding: 2px 5px; } /* Sub Menu Styles */
#nav li:hover ul, #nav li.sfhover ul,
#nav2 li:hover ul, #nav2 li.sfhover ul { display: block; } /* The magic */
#nav2, #nav2 ul {
width: 100%;
}
#nav2 li {
float:left; /* makes the main nav horizontal */
width:80px; /* Width of Menu Items */
margin:0;
}
#nav2 li ul {
position: absolute; /* positions and sets width of submenus */
display: none;
float:left;
margin:0;
}
#nav2 li ul li {
position:relative;
float:none; /* stops the submenus from being horizontal */
}
/* Styles for Menu Items */

I need to link to differnt style sheets to a page and i need it so it will use one if the user has IE and a differnt one if the user is using anything else that works properly. Is this posable and if it is please tell me how? and if theres a way of doing it that uses php i would like to use that method. thanks I have been reading alot about how much trouble we get into with IE when trying to center a div. I had a lot of trouble with it and mainly just wanted to have a fixed width site (760px or so) with a thin border all the way around it. Is the following code a good way to accomplish this? Code: <head>
<style type="text/css">
body {
margin: 0px;
padding: 0px;
}
div {
border: 1px solid #666666;
height: 100%;
width: 100%;
}
</style>
</head>
<body>
<table width="770" border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td><div></div></td>
</tr>
</table>
</body>
I am planning on having this as my index page and just using an "include" for the different header/body/footer elements. Would love some advice/opinions. Viewing this page in Firefox: http://moneyextra.thehelpgroup.co.uk/compare/creditcards/ProductDetails.php?index=79 - it looks fine, but when you view it in IE 6, it is really messed up Does anyone know whats causing that to happen and how I would fix it Thanks alot |
