css problem with default input type="text"

[Hansjörg Meuschel]

Hello,
how do I define a default background color for text input elements 
only(!) in css?

Defining something like
input {
   background-color: #EFEFEF;
}
makes all buttons look ugly so I'm searching for a way to define this 
for text type inputs only...

any ideas?
greets hans
