How to hide Recycle Bin and All Site Content in SharePoint 2010

If you want to hide Recycle Bin and All site Content in the Quick Launch menu in SharePoint 2010, you can use custom CSS for this.

For one of our customers, we've created a custom CSS named CoreOverrides.css in SharePoint 2010. In this CSS we inserted a display:none element as follows:

/* Hide All Site Content and Recycle Bin */
.s4-specialNavLinkList
{
display:none !important;
}
