Hi, I have a list of tabs the headers (H2) of which are styled in a stylesheet, I now want to style an individual tab to be a certain color but cant seem to be able to do this.
When I set the color locally the stylsheet style overides anything?

HTML

Code:

<div class="tabber">

<div class="tabbertab">

<h2>Title I want to change</h2>
<p>Content
</p>

</div>

<div class="tabbertab">

<h2>Title 2</h2>
<p>Content
</p>

</div>

</div>

CSS

Code:

.tabberlive .tabbertabhide {
display: none;
}

.tabber {
padding: 0px;
}

.tabberlive {
margin-bottom: 10px;
}

ul.tabbernav {
margin: 0;
padding: 0px 0;
color: #202020;
font-size: 12px;
font-family: Arial, Tahoma, Verdana;
font-weight: normal;
}

ul.tabbernav li {
list-style: none;
margin: 0;
display: inline;
}

ul.tabbernav li a {
padding: 3px 0.5em;
border-bottom: none;
text-decoration: none;
}

ul.tabbernav li a:link {
color: #202020;
background: #DDDDDD;
margin: 0px 5px 0px 0px;
}

ul.tabbernav li a:visited {
color: #202020;
background: #DDDDDD;
}


ul.tabbernav li a:hover {
background: #666666;
color: #FFFFFF;
text-decoration: none;
}

ul.tabbernav li.tabberactive a {
background: #333333;
color: #FFFFFF;
text-decoration: none;
}

ul.tabbernav li.tabberactive a:hover {
background: #333333;
color: #FFFFFF;
}

.tabberlive .tabbertab {
background: #FFFFFF;
padding: 10px 0px 0px 0px;
}

.tabberlive .tabbertab h2 {
display: none;
}

.tabberlive .tabbertab h3 {
display: none;
}

.tabbertab cite {
font-size: 11px;
margin: 0px;
padding: 0px;
}

How could I set the H2 Title so I could style just that one?

Hello millsy007,
There are a few different ways. If this is only happening the one time, maybe inline styles would be fine to use.
I'd probably do it by giving that <h2> an id or class, <h2 class="active"> , and and change it's color by styling that.

Hi,
When I set the color locally the stylsheet style overides anything?
Yes. You may style it locally. Not an elegant solution, but a safe one.

Hi, I tried but:

<h2 style="color:#FFFF99">Platinum</h2>

doesnt change anything?

That should work millsy007,
Maybe it's the color you've picked? What is the background color of the behind the h2?

Inline styles should always over-ride styles from the attached or linked CSS. See this example with the text of the document set to #fff -
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style type="text/css">
body {
background: #000;
color: #FFF;
}
</style>
</head>
<body>
<h1>white</h1>
<h2 style="color:#FFFF99">Platinum</h2>
</body>
</html>

Hi

It seems no matter what I set locally (color, size etc) the css is setting the style.
The tab section is using javascript to set styles could this be a factor?

This bit here changes the color and background of the "Title I want to change" button -


ul.tabbernav li.tabberactive a {
background: #333333;
color: #FFFFFF;
text-decoration: none;
}

This works here for me -


ul.tabbernav li.tabberactive a {
background: #f00;
color: #fc6;
text-decoration: none;
}


The js doesn't appear to do any of that.
Am I misunderstanding your question?

Thanks, but my issue is that I only want to style one of the tabs not all of them.

So for


<div class="tabber">

<div class="tabbertab">

<h2>Title I want to change</h2>
<p>Content
</p>

</div>

<div class="tabbertab">

<h2>Title 2</h2>
<p>Content
</p>

</div>

</div>

I would only want to style:


<h2>Title I want to change</h2>

Your .js is re-assinging id's and classes along with building the ul's. It gives <h2>Title I want to change</h2> the class .tabberactive which can be styled from the CSS I quoted.
This is a very confusing way to make a list, not to mention that it does not work for anyone with javascript disabled.

millsy007
01-07-2010, 12:42 AM
Thanks, I agree that it is confusing and not so broswer friendly but it is used on a wordpress theme I have installed.
I just want to make that one H2 tage be styled differently, where would I need to do this, if I alter the .tabberactive class surely they would all change?

Did you try it? There is only one .tabberactive on the markup I ended up with so it changes the "Title I want to change" just fine. I did not study that .js to figure out how it decides what h2 gets what class.
I have also never messed with wordpress, but this does seem like a backward way of doing things. You are locked into this js? There is no way to just not use it?

millsy007
01-07-2010, 01:12 AM
My understanding is that the tabberactive is simply the tab that has been clicked on, this will change as I will have more than 2 tabs.
Ideally I want a way to specifically style the <h2>Title I want to change</h2> tab locally?
I am pretty much locked into this code, I didnt imagine it would be so tricky to alter one tags style, guess I was wrong :(

Excavator
01-07-2010, 01:16 AM
Just try
ul.tabbernav li.tabberactive a {
background: #f00;

text-decoration: none;
}

Hi, thanks but this doesnt do what I need, I only ever want that one tab to be styled, this sets a generic value where other tabs I added that are active would be set to that color.

Excavator
01-07-2010, 01:42 AM
Ah, I understand now! Sorry for being so dense.
If that is the first item in your list you may be able to use a first-child selector. Have a look at this - http://meyerweb.com/eric/articles/webrev/200007b.html
or
http://robertnyman.com/2009/02/04/how-to-solve-first-child-css-bug-in-ie-7/

Otherwise, you may need to learn how to edit js.

millsy007
01-07-2010, 03:03 AM
Thanks, not sure this will work though as its actually the last tab item (typical) and its not in a list but a series of <div> tags.
Do you think it would be possible to apply the same theory and get it working?

Thanks, not sure this will work though as its actually the last tab item (typical) and its not in a list but a series of <div> tags.

Well, be careful there. You may be coding it in divs but that js is putting it in <ul> <li> format. Check the outputted code of your document after the javascript is done and you'll see what I mean.

And there is also a li:last-child but I'm not sure how many browsers support it.

millsy007
01-07-2010, 12:18 PM
Thanks, I tried:

ul.tabbernav li:last-child {
background: yellow;
}

And in firefox it showed an overlap of yellow background, so thats something.
Do you think using similar markup I could style the text.
Setting color: yellow; doesnt work.
I was thinking I may need to wrap the text in a <span> element?

Excavator
01-07-2010, 05:47 PM
What wordpress theme is this? I'd like to take it apart and see what the heck is going on. I can't imagine actually wanting that .js reconfiguring your markup, there must be some way to get rid of that.

millsy007

It is called revolution pro, im not sure where you get it as my friend had installed it and im helping (trying to) with site.

Agreed that it seems messy, thought there may be a workaround though, do you think puttting the text in a <span> or <p> div may do anything?

Excavator
01-07-2010, 08:28 PM
do you think puttting the text in a <span> or <p> div may do anything?

Normally I would say yes. Of course, normally you don't have a javascript re-formatting your markup.

Have you tried it?

Revolution Pro (http://www.studiopress.com/?ev=75da123858) seems to be an $80 WordPress theme from StudioPress.
Included in that purchase price is Support and Tutorials.
Maybe you should have a look there (http://www.studiopress.com/support).
