Align text only on first separator in VIM

Question

Suppose I have this code:

width: 215px;
height: 22px;
margin-top: 3px;
background-color: white;
border: 1px solid #999999;

I want to align it this way:

width:            215px;
height:           22px;
margin-top:       3px;
background-color: white;
border:           1px solid #999999;

using Align.vim I can do :Align \s to use whitespace as separator, but that has 2 problems

1. the initial indent is doubled
2. all whitespaces are considered separators, so the last line is messed up

I've read through the many options Align.vim offers, but I haven't found a way to do this.

Answer 1

If you use Tabular, then you can just do :Tabularize /:\zs/.

Looking at Align's description on vim.org, a similar invocation should work for it. You could try :Align :\zs. I don't use Align, so I'm not positive.
