One mixin to rule them all
Zass is a Sass (CSS) fluid grid framework. Zass is 100% fluid, semantic, clean and allow infinite nesting of columns with the use of a single mixin.
- 100% fluid because it only uses percentage units to create grid dimensions.
- Semantic, because thanks to Sass CSS pre-processor there is no need to pollute HTML with design named classes (as
.col_4
to indicate 4 grid units width). - Clean because it does not use any CSS hack neither uggly negative margins. Zass does not care about obsolete browsers like Internet Explorer 6.
- Zass can nest infinite levels of columns.
- And, what is more awesome, Zass can do all of this using one single mixin.
Zass framework requires you are working with Sass.
With git, to get latest stable version:
git clone https://github.com/waiting-for-dev/zass.git
Otherwise, download it from:
https://github.com/waiting-for-dev/zass/zipball/master
Move zass files to your sass directory and import sass/_zass.scss
from your sass stylesheet:
@import 'sass/zass';
First of all, you have to configure your grid through three variables. Here it is an example for a 960px grid:
$zass-column-width: 60px; //Grid columns width
$zass-gutter-width: 20px; //Grid gutters width
$zass-grid-units: 12; //Grid number of columns
Then, you are ready to start creating and nesting as many columns as you want using the zass-column()
mixin:
zass-column($n, $parent-n, $position, $push, $pull);
Here it is an explanation of zass-column
parameters:
$n
: amount of grid units that the column will take up.$parent-n
: Only for nested columns, amount of grid units that the parent column takes up. 0 means it is not a nested column.0
is the default.$position
: Only for nested columns, it can beleft
,right
orinner
if a column is the left extreme one, the right extreme one or an inner one.inner
by default.$push
: Amount of grid units to push (left margin) the column$pull
: Amount of grid units to pull (right margin) the column
So, let say you have following DOM structure:
<div id="col1">
<p>Column 1</p>
</div>
<div id="col2">
<div id="col2-1">
<p>Column 2-1</p>
</div>
<div id="col2-2">
<p>Column 2-2</p>
</div>
</div>
<div id="col3">
<p>Column 3</p>
</div>
With Zass, you could build quickly a grid layout:
@import '../../zass';
$zass-column-width: 60px;
$zass-gutter-width: 20px;
$zass-grid-units: 12;
#col1 {
@include zass-column(3); //Take up three grid units
}
#col2 {
@include zass-column(7); //Take up seven grid units
#col2-1 {
@include zass-column(4, 7, 'left'); //Take up 4 grid units inside #col2. It's the left one.
}
#col2-2 {
@include zass-column(3, 7, 'right'); //Take up 3 grid units inside #col2. It's the right one.
}
}
#col3 {
@include zass-column(1, $push: 1); //Take up one grid unit and push one more.
}
Optionally, you can use a second mixin, zass-grid()
, if you want to set grid width as the maximum width for a given container. That way, a perfect pixel photo of a design is achieved for resolutions greater or equal than grid pixel width while it is still 100% fluid for lower resolutions:
zass-grid($em, $rfs)
$em
: If true, set that maximum width in em. In that case, the grid will increase its width if user increases text zoom level. Defaults totrue
.$rfs
: Relevant font size to calculate maximum width in em units. Default to16px
.
In our example:
#wrapper {
@include zass-grid(true, 16px); //It ouputs "max-width: 60em;"
}
or
#wrapper {
@include zass-grid(false); //Will ouput "max-width: 960px;"
}

directory for more examples.
