Hiding "View All Site Content"

Always using Deigner for alteration is really not a recomended approch.
Here is an alternative solution I figured for hiding the "View all site contents " from a site.

[Note: add <>
style>
#ctl00_PlaceHolderLeftNavBar_idNavLinkViewAll
{ Visibility:hidden; }
/style>
Also if you want the "View all site content" should be placed below Site Action button there is an artical published by Mark Wagner Click here to read more on this.
