How can I style even and odd elements?

Is it possible to use CSS pseudo-classes to select even and odd instances of list items?

I'd expect the following to produce a list of alternating colors, but instead I get a list of blue items:

li { color: blue }
li:odd { color:green }
li:even { color:red }
<ul>
    <li>ho</li>
    <li>ho</li>
    <li>ho</li>
    <li>ho</li>
    <li>ho</li>
  </ul>

The problem with your CSS lies with the syntax of your pseudo-classes.

The even and odd pseudo-classes should be:

    li:nth-child(even) {
        color:green;
    }

/* and */

    li:nth-child(odd) {
        color:red;
    }

Working: nth child with number and odd even

.ziehharmonika:nth-child(1) h3 {  /*select number one child*/
    background-color: green;
}

.ziehharmonika:nth-child(odd) h3 {
    background-color: red;
}

.ziehharmonika:nth-child(even) h3 {
    background-color: yellow;
}

Use this:

li { color:blue; }
li:nth-child(odd) { color:green; }
li:nth-child(even) { color:red; }

But it's not working in IE.

Recommend using :nth-child(2n+1) :nth-child(2n+2)

li {
    color: black;
}
li:nth-child(odd) {
    color: #777;
}
li:nth-child(even) {
    color: blue;
}
<ul>
    <li>ho</li>
    <li>ho</li>
    <li>ho</li>
    <li>ho</li>
    <li>ho</li>
</ul>

The :nth-child(n) selector matches every element that is the nth child, regardless of type, of its parent. Odd and even are keywords that can be used to match child elements whose index is odd or even (the index of the first child is 1).

this is what you want:

<html>
    <head>
        <style>
            li { color: blue }<br>
            li:nth-child(even) { color:red }
            li:nth-child(odd) { color:green}
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>

the css odd and even is not support for IE. recommend you using solution below.

Best solution:

li:nth-child(2n+1) { color:green; } // for odd
li:nth-child(2n+2) { color:red; } // for even

li:nth-child(1n) { color:green; }
li:nth-child(2n) { color:red; }

<ul>
  <li>list element 1</li>
  <li>list element 2</li>
  <li>list element 3</li>
  <li>list element 4</li>
</ul>
