"Try to keep similar properties grouped together"

[nicetransition]

I have been using alphabetical because I think that trying to keep similar properties grouped together is so subjective.

If we make this a standard, can we add documentation on what "similar properties" means? And include details on using CSSComb and setup for keeping "similar properties grouped together"

[LukeAskew]

Does this reference suffice?

http://www.w3.org/wiki/CSS/Properties

[nicetransition]

What about order or these groups? Is there a setup for CSS Comb that you are aware of that does a good job of this?

If we do this can we do that? CSSComb support is crazy awesome

[nicetransition]

Have you used CSS Comb? If we say that it's a standard, we should use CSSComb.

// Before CSSComb
    .foo {
        box-sizing: border-box;
        -moz-box-sizing: border-box;
        -webkit-box-sizing: border-box;
        color: #010101;
        display: inline-block;
        font-size: 2em;
        font-style: normal;
        font-weight: 300;
        height: 100vh;
        line-height: 1;
        margin: 0;
        overflow-y: hidden;
        padding: 0;
        -webkit-overflow-scrolling: touch;
        width: 50%;
        .bar {
            height: 100%;
            left: 0;
            position: absolute;
            top: 0;
            width: 100%;
        }
    }

// After CSSComb    
    .foo {
        display: inline-block;
        overflow-y: hidden;
        -webkit-box-sizing: border-box;
        -moz-box-sizing: border-box;
        box-sizing: border-box;
        margin: 0;
        padding: 0;
        width: 50%;
        height: 100vh;
        color: #010101;
        font-weight: 300;
        font-style: normal;
        font-size: 2em;
        line-height: 1;
        -webkit-overflow-scrolling: touch;
        .bar {
            position: absolute;
            top: 0;
            left: 0;
            width: 100%;
            height: 100%;
        }
    }

So looks like there are some weirdness with -webkit-overflow-scrolling, but you can easily fix that by adding:

Now the question is, do we add spacing between property groups?

[apartyka]

I think it looks fine without the spacing. Easier to scan imo.

Is that an option you can pass to the settings? (where to place line breaks). Your example is more convincing.
