CentOS 7 hidden taskbar and top bar

I use GNOME, for the use of Windows I, this interface is indeed a bit ugly, but, will also be used, recently found a software (Cairo-dock) can beautify the desktop, and then installed, but after the installation found a problem: The original taskbar blocks the interface of the software, so you can find ways to hide the taskbar

1. Hide the taskbar

Delete/usr/share/gnome-shell/extensions/[email protected]extensions.gcampax.github.com directory

Before deleting the backup, need administrator rights, I directly back up to the directory, the bottom of the operation is done in/usr/share/gnome-shell/extensions/

CP [Email protected] [Email protected]

Delete

RM -RF [email protected]

These two steps can also be solved directly

MV CP [Email protected]

2. Hide the top bar

Three files need to be modified, namely/USR/SHARE/GNOME-SHELL/MODES/CLASSIC.JSON,/USR/SHARE/GNOME-SHELL/THEME/GNOME-CLASSIC.CSS and/usr/ Share/gnome-shell/theme/gnome-shell.css

/usr/share/gnome-shell/modes/classic.json

Back up first, go to the/usr/share/gnome-shell/modes/directory

CP Classic.json classic.json.backup

Modify the content, vi in the command mode can use "/keyword" to find

VI Classic.json

Modify the following

 

 "panel":{ "left": [],
    "center": [],
     "right": []
   }

/usr/share/gnome-shell/theme/gnome-classic.css

Again, back up first.

Modify the following

 
#panel {

    background-color: #e9e9e9;

    background-gradient-direction: vertical;

    background-gradient-end: #d0d0d0;
    border-top-color: #666; /* we don‘t supportnon-uniform border-colors and
                               use the top bordercolor for any border, so we
                               need to set iteven if all we want is a bottom
                               border */
    border-bottom: 1px solid #666;
    app-icon-bottom-clip: 0px;
     color: transparent;
     /* hrm, still no multipoint gradients
      background-image: linear-gradient(left,rgba(255, 255, 255, 0),rgba(255, 255, 255, 1) 50%，rgba(255, 255, 255, 0)) !important;*/
   }

/usr/share/gnome-shell/theme/gnome-shell.css Change two places

Last emphasis, back up

 
//The first place
#panel {
     background-color:transparent;
     font-weight: bold;
     height: 0px;
    }
//Second place
  .panel-logo-icon {
   padding-right: .4em;
   icon-size: 1px;
   }

Original code

    "stylesheetName": "gnome-classic.css",
    "enabledExtensions": ["[email protected]","[email protected]","[email protected]","[email protected]","[email protected]"],
    "panel": { "left": ["activities", "appMenu"],
               "center": [],
               "right": ["a11y", "keyboard", "dateMenu", "aggregateMenu"]
             }
}

/usr/share/gnome-shell/theme/gnome-classic.css

 
#panel {
    background-color: #e9e9e9;
    background-gradient-direction: vertical;
    background-gradient-end: #d0d0d0;
    border-top-color: #666; /* we don‘t support non-uniform border-colors and
                               use the top border color for any border, so we
                               need to set it even if all we want is a bottom
                               border */
    border-bottom: 1px solid #666;
    app-icon-bottom-clip: 0px;

/* hrm, still no multipoint gradients
    background-image: linear-gradient(left, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 50%, rgba(255, 255, 255, 0)) !important;*/
}

/usr/share/gnome-shell/theme/gnome-shell.css

//I changed it later. I forgot to back it up. It can be displayed normally, almost the same as before.
#panel {
     background-color: #fff;
     font-weight: bold;
     height: 1.8em;
} 

 
 
.panel-logo-icon {
