remove buttons from custom field via css

Hello,

for a custom record, I add a permission for customer center with full access, and a link to customer center to appear in my account tab.
When the customer open a record, there is the following buttons displayed:

Edit, new, make copy, print 

and when he try to edit a record, there are also the following buttons:

save, make copy, save and new, save and copy, delete, reset

and I included items sublist, so for this sublist the customer can attach and remove items. (there is attach record)

What I want to do is:

[LIST]
[*]remove all buttons in view mode except Edit button
