Hide Upload Document item in Sharepoint Ribbon

It hid the Upload button and am hiding the Add New with the Main web part zone:

Using CSS

<style type="text/css"> 
#Ribbon\.Documents\.New\.AddDocument-Large
{     
 display:none !important; 
} 
</style>
<style type="text/css"> 
td.ms-addnew
{     
 display:none !important; 
} 
</style>
