Avoid universal selectors with a better box model in Sass/Compass.

gistfile1.sass

// Inside my base include file which includes Compass.
%bs-border-box { @include box-sizing(border-box); }

// Inside my application Sass file.
@each $el in elements-of-type('block') { #{$el} { @extend %bs-border-box; } }

// Generates the following CSS.
address, article, aside, blockquote, center, dir, div, dd, details, dl, dt, 
fieldset, figcaption, figure, form, footer, frameset, h1, h2, h3, h4, h5, h6, 
hr, header, hgroup, isindex, menu, nav, noframes, noscript, ol, p, pre, 
section, summary, ul { 
  -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box;
}

Learn about box-sizing: border-box on Paul's blog post and then learn about Compass' elements-of-type function from their source code on github.

Also, learn about Sass silent classes, called placeholder selectors, on Dale's speakerdeck presentation.

Is there any advantage to this approach over using the * selector?
