About CSSe
CSSe is an unofficial CSS format extension, introducing variables and class mixins to speed up CSS writting and logically organize CSS structure.
The reason for CSSe is that CSS have no such features yet and LESS, SASS, etc. things seem overcomplicated.
CSSe format example:
/* These are variables that can be used in place of property values. */ _vars { gap_min: 10px; gap_med: 15px; gap_max: 30px; gap: @gap_min; /* A variable can reference another variable as long as the latter was previously defined. */ } .indent_left { /* Get value from variable `gap`. */ margin-left: @gap; } .brand_box { background-color: @color_brand; margin-bottom: @gap_med; margin-top: @gap_min; color: @color_subtle; } /* One can declare additional variables as necessary. */ _vars { color_brand: #5f9ea0; color_subtle: #f0fff0; } /* Any block can borrow properties from other classes. */ blockquote { /* We borrow properties from `indent_left` class. */ mix: indent_left; /* And we borrow properties from `brand_box` class. */ mix: brand_box; margin-bottom: @gap_max; }
The above example is translated into the following CSS:
.indent_left { margin-left: 10px; } .brand_box { background-color: #5f9ea0; margin-bottom: 15px; margin-top: 10px; color: #f0fff0; } blockquote { margin-bottom: 15px; margin-left: 10px; background-color: #5f9ea0; margin-top: 10px; color: #f0fff0; }
Usage
import pycsse if you want to use it as module. Use CsseParser and CssExporter classes.
Exec ./pycsse.py -h from command line to get help on utility usage.
Export CSSe from my_csse.css into minified CSS file named my_css.css:
./pycsse.py -o my_css.css my_csse.css
