How to select the first, second, or third element with a given class name?

Question

How can I select a certain element in a list of elements? I have the following:

<div class="myclass">my text1</div>
<!-- some other code follows -->
<div>
    <p>stuff</p>
</div>
<div>
    <p>more stuff</p>
</div>
<p>
    <span>Hello World</span>
</p>
<div class="myclass">my text2</div>
<!-- some other code follows -->
<div>
    <p>stuff</p>
</div>
<p>
    <span>Hello World</span>
</p>
<input type=""/>
<div class="myclass">my text3</div>
<!-- some other code follows -->
<div>
    <p>stuff</p>
</div>
<footer>The end</footer>

I have the CSS class div.myclass {doing things} that applies to all, obviously, but I also wanted to be able to select the first, second, or third div of class .myclass like this, regardless of where they are in the markup:

div.myclass:first {color:#000;} 
div.myclass:second {color:#FFF;} 
div.myclass:third {color:#006;}

Almost like the jQuery index selection .eq( index ), which is what I am using currently, but I need a no-script alternative.

To be specific, I am looking for pseudo selectors, not things like adding another class or using IDs to make things work.

Answer 1

use nth-child(item number) EX

<div class="parent_class">
    <div class="myclass">my text1</div>
    some other code+containers...

    <div class="myclass">my text2</div>
    some other code+containers...

    <div class="myclass">my text3</div>
    some other code+containers...
</div>
.parent_class:nth-child(1) { };
.parent_class:nth-child(2) { };
.parent_class:nth-child(3) { };

OR

:nth-of-type(item number) same your code

.myclass:nth-of-type(1) { };
.myclass:nth-of-type(2) { };
.myclass:nth-of-type(3) { };
