Option to set multiple class

Is there any option to set multiple class on a single element. For example, I have two style sets defined as

Code:
<style>
.style1{text-decoration: none;}
.style2{color: red;}
</style>

I tried to set both the style set for an element using class attribute as below. But it does not work. Is there any other option.

Code:
<a href="" class="style1,style2">

You are close
<a href="" class="style1 style2">

Thanks Aerospace_Eng.. that helped me a lot..
