So I ve recently been playing around with CSS compilers, but I have no idea how (or if it s possible) to dynamically generate pieces of a selector.

For instance, let s say I wanted to make mixins to get

display: inline-block;

to work cross browser. I would have to do the styles, yeah, but I would have to do the IE6/7 selector hacks to get them to work in those browsers too. Ideally I m looking for a one off thing to add to an element and have the ability for that to work. Some kind person recently gave me this solution: CSS compilers and converting IE hacks to conditional css

and it would be nice to implement that in a minimal way that would allow me to specify it for a given element and be on my way (for instance in Less, you can create a class with styles, pass that class to another element, and that element will inherit all of those styles. It would be nice to pass an element .inline-block; and it create the styles needed to support IE6/7 without having to resort to stuff like

_color: pink;

Any ideas?

EDIT: for instance as well, how could I do something like clearfix for LESS? (lesscss.org)? If Sass can only do it then that will work too.

Answer 1

So I did some digging in the documentation, and some experimentation, and Sass (to my relief) supports this, though I don t think LESS does (which is why it s getting dropped in favor of Sass).

You can use the ampersand as a pointer to the selector you used in the definition, and the position of that ampersand in a nested declaration doesn t have to be at the front, you can put selectors before it. For instance, you can use conditional IE tags on to target IE in the same stylesheet in a way that doesn t use hacks. The following uses the SCSS notation (but should work fine with the indentation notation):

@mixin inline-block {

// Cross browser implementation of the inline-block attribute

  display: inline-block;
  body.ie6 & { display: inline; }
  body.ie7 & { display: inline; }

}

And all you have to do is drop this on anything you want:

#foo { @include inline-block; }

and it will generate/manage all the your inline-block stuff cross browser:

#foo { display: inline-block; }
body.ie6 #foo { display: inline; }
body.ie7 #foo { display: inline; }

Semantic way of handling cross-browser issues, no more having to deal with the cumbersome method of managing 2 different files for styles (which is asinine to me), no more code block eyesores.

Edit: Of course that functionality was stated in the old documentation, not in the new, which is why I couldn t find it.

Answer 2

A cross-browser implementation of inline-block is provided by compass, a framework built on top of sass:

Here you van see the crossbrowser solution for inline blocks. simple and short.

Above example will not give a layout to the element in IE. You need zoom for example.
