CSS3: box-sizing

[Axel Dahmen]

Hi,

this has certainly been discussed within W3C, but I'd like to give my humble
comment here, too...

Using the current (CSS compliant) width/height handling it is not possible
to easily add full width background to any block element.

Currently, I'm responsible for adding a coloured background around headers
for certain customers. The header background should be coloured and "width:
100%;". Using IE quirks handling, I'd have written something like this:

h1,h2,h3,h4,h5, h6,h7
{
background-color: green;
color: black;

width: 100%;

padding: 1em 3em;
border: 2px solid darkgreen;
margin: 0 0 1em;
}

This works fine, no need to add a div, table or anything around each and
every header element... However, in CSS 2.1 I can't find any setting that
possibly could achieve something like this.

So here's my personal vote to those being responsible to decide about new
CSS specifications: Please positively add the "box-sizing" property to CSS.
It will fill a gap in the current 2.1 specification for sure. [Again, this
is just my humble opinion. Anyone coming up with a pure CSS 2.1 compliant
solution, and I will immediately change my mind ;) ]

'width: auto', which is the default value, will do what you want, as
far as I can tell.

Thanks David, for giving me this hint! You are right, according to the specs
your suggestion is going to work, I see it now. I forgot because I
remembered a Netscape version - I believe it was v6 - which rendered a
minimum box around blocks if I didn't explicitly set with to 100%. But, of
course, it wasn't compliant at that time. Yet it stuck to my mind, though.

Thanks for helping me out.

Regards,
Axel
