Help With Button Sizing Options

[English]

I have the following code in my CSS for a button.

button {
background-color:#005100;
border-radius:28px;
border:3px double #FAFAF9;
display:inline-block;
cursor:pointer;
color:#ffffff;
font-family:Arial;
font-size:16px;
padding-top:3px;
padding-right: 8px;
padding-left: 8px;
padding-bottom: 3px;
text-decoration:none;

}

My text is wrapping and I don't want it to. So how can I either specify the fixed width or make the text not wrap?
Thanks
Alan
