Visual Studio 2010: highlight CSS text and comment

Consider a snippet of CSS code from a .css file in Visual Studio 2010 to be commented out.

Visual Studio 2010: highlight CSS text and comment

Normally Ctrl + E , Ctrl + C will comment your selected HTML and other source code.

But highlighting CSS code & executing that shortcut combo results in a warning message:

The key combination is bound to command (Comment Selection) which is not currently available.

Is there a toolbar or keyboard shortcut in Visual Studio 2010 to comment the h开发者_StackOverflowighlighted CSS text for you?


Comment Selection command is not available for css files.

However, you can create a simple macro and assign a keyboard shortcut to it...

Sub CommentCSS()
    Dim selection As String
    selection = DTE.ActiveDocument.Selection.Text
    selection = "/*" + selection + " */"        
    DTE.ActiveDocument.Selection.Text = selection
End Sub

To 'uncomment' the selection use another simple macro:

Sub UncommentCSS()
    Dim selection As String
    selection = DTE.ActiveDocument.Selection.Text
    selection = selection.Remove(0, 2)
    selection = selection.Remove(selection.Length - 2, 2)
    DTE.ActiveDocument.Selection.Text = selection
End Sub
