CSS - Using Js To Change Css Class
I have a form with a list of things. The number of things in the list is variable, depending on certain factor, different things, different numbers of things. Next to each thing is a radio button.
There is a question with two radio buttons, "yes" and "no". When "no" is selected, I want the radio buttons to be disabled, and the color of the text to change to gray. For the radio buttons, I have a simple JS function: javascript Code: Original - javascript Code function enableCFFID() { document.cartform.cffid.disabled=false; } function disableCFFID() { document.cartform.cffid.disabled=true; }
For the test that goes with each thing, obviously I don't want to have to assign unique ID (perhaps in a span tag that encloses the text). I would want a common name for all of them. But this would mean I can't use getElementById. What other method can I use to change the class for a group of span tags who's number is variable? Similar Tutorialshey, 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 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 believe the importance of css styling is external, internal head, internal tag (from least to most) problem i have is that there is a tag that looks like so.. <div style="width:420; height:120; overflow: hidden;"> </div> I need to put stuff inside this box that defies those commands... and since the tag doesnt have a class or id, it is difficult to do anything like add the !important tag or anything... I know there is inherit, is there a opposite of inherit, so i can force that tag to do what i want? Hey guys, I'm hoping what I need to do involves only CSS (though, it wouldn't shock me if I needed a lot more!) Anyways, the basic thing I'm doing is a table that hold lots of numbers. I'm creating a "times table" - which looks roughly something like this: ......1 2 3 //top row (multiples) 1.....1 2 3 2.....2 4 6 3.....3 6 9 Now, when you rollover, let's say, the '6' - the TD background color for the '6', left '2' and top '3' would change to a different color (bolded in this example). This would work the same way for every other number as well, which involves overlapping classes. I can only get one rollover working, with simple 'hover' commands. I've search for an answer for hours, to no avail. any suggestions? And here's a more "code specific" example of the table: <table> <tr> <td>1</td><td>2</td><td>3</td> </tr> <tr> <td>1</td><td>1</td><td>2</td><td>3</td> </tr> <tr> <td>2</td><td>2</td><td>4</td><td>6</td> </tr> <tr> <td>3</td><td>3</td><td>6</td><td>9</td> </tr> </table> Thanks so much guys! Hello everyone. I have a site that uses a PHP command to pull the PHP modifier from the URL and use that as a class for a header. Those classes each have their own BG image in my external stylesheet. On any browser other than IE win it works fine, headers change as the class changes. On IE win though only the first one (my "about" class) works, the rest default to the standard header. I have re-typed the rest to see if it was just a text problem but nope. Everything validates fine. The page is http://holiday.mrpunkin.com/about.php My classes are as follows: they all modify the "mid" div as you can see: Code: #mid.about {background: transparent url("/img/headers/mid_about.gif");}
#mid.activities {background: transparent url("/img/headers/mid_activities.gif");}
#mid.food {background: transparent url("/img/headers/mid_food.gif");}
#mid.travel {background: transparent url("/img/headers/mid_travel.gif");}
#mid.resident {background: transparent url("/img/headers/mid_res_rel.gif");}
#mid.health {background: transparent url("/img/headers/mid_health.gif");}
#mid.fitness {background: transparent url("/img/headers/mid_fitness.gif");}
#mid.maintenance {background: transparent url("/img/headers/mid_bg.gif");}
#mid.construction {background: transparent url("/img/headers/mid_construction.gif");}
#mid.employment {background: transparent url("/img/headers/mid_employment.gif");}
Does anyone know why IE Win won't recognize the different BG images and use those? When I view the source I can tell that its outputting the class name correctly, so thats not the issue. Please get back to me asap. Thanks. hii plz tell me how can i change my td css class,when i click on tht particular td. what will be the syantax plz reply by mail or post . 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">

<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 have a button which is drawn using css background-image and it has a hover effect using css a:hover. I also need to have a click state for this button, so that each time the button is clicked it switches between two different states (4 states total). Is this possible? I'm assuming this will probably require JavaScript which I have little experience. Thanks in advance for any help! 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... 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 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 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! 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! 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? Problem solved. Just wondering why this code dosent work? I want to have image mapping and i want it to be under a class so thatt in my style sheet i can move it anywhere i want. Html code Code: <img class="20sub" img id="20sub" src="images/20sub.gif" usemap="#20sub" border="0" width="130" height="123" alt="20sub" /> <map id="20sub" name="20sub"> <area shape="rect" coords="0,0,125,118" href="http://www.google.com" alt="20sub" title="20sub" /> </map> Style code Code:
.20sub
{
position: absolute;
right: 640px;
top: 150px;
}
Thank you for all the help 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 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, saj |
