// FORMTASTIC SASS
// Flexible styling for formtastic forms
// http://www.github.com/active-stylus/formtastic-sass
//
//--------------------------------------------------------
// STACKED FORMS
// Labels fill up the full width of the form
// Inputs are on new lines
//--------------------------------------------------------
//
// Arguments:
//
// +form-stack(full-width, input-width, submit-button-align)
//
// Example:
//
// form.formtastic
//   +form-stack(300px,"full","right")
//
// Default Settings:
//
!stacked_fieldset=100%
// Full width of the fieldset
//
!stacked_input="auto"
// "auto"   = automatic widths
// "full"   = same width as form
// "960px"  = custom width
//
!stacked_padding=0
// Left padding on all labels and inputs
//  
!stacked_button_align="buttons-left"
// "buttons-left"   = float submit button left
// "buttons-right"  = float submit button right
// "buttons-full"   = submit button matches input width
//
!stacked_select_width = "select-auto"
// "select-auto"   = default width
// "select-full"  = same as specified input width
//
//--------------------------------------------------------
// FLOATED FORMS
// Column layout with labels left of the inputs
// Comes in 2 flavors for text alignment of the labels
//--------------------------------------------------------
//
// Arguments:
//
// +form-labels-left(total-width, label-width, input-width, label-padding-x, submit-align)
//
// Examples:
//
// form.lefty
//   +form-float-left(800px,500px,200px,6px,"buttons-left")
//
// form.righty
//   +form-float-right(800px,500px,200px,6px,"buttons-left")
//
//--------------------------------------------------------
// Default Settings:
// (do not mix units because calculations are made)
//
!floated_total_width = 100%
// Total Width of form
//
!floated_input_width = 70%
// Width of inputs
//
!floated_label_width = 20%
// Width of Label
// 
!floated_label_padding_x = 0
// How far labels are spaced from inputs
//
!floated_button_align = "buttons-left"
// "buttons-left"   = float submit button left
// "buttons-right"  = float submit button right
// "buttons-full"   = submit button matches input width
//
!floated_select_width = "select-auto"
// "select-auto"   = default width
// "select-full"  = same as specified input width

//
!total_width=100%

// Set width of inputs, textareas and selects
//
!label_pad=2%
// Set horizontal padding for labels

//
!label_float="left"
// Set alignment of labels
// "clear" puts labels above inputs
// "left" floats labels left and aligns text left
// "right" floats labels left and aligns text right
       
//
// Set widths of all inputs, textareas and selects (all aligned)
// False will preserve auto width

// Installation ------------------------------------------
//
//$ sudo gem install haml
//$ cd rails app
//$ haml --rails (or merb/sinatra/etc)
//
// Set up master Sass file and include it in your html
// Save this file as _base.sass and include it in master sass like so:
//
// @import base.sass   
//
// Usage -------------------------------------------------
//
// form.formtastic
//   +formtastic-float
//
//  This will provide forms of columns with label floated left
//  For label on top of inputs you can use
//
// form.formtastic
//   +formtastic-block
//
// Customize ---------------------------------------------
//
// form.formtastic
//   +formtastic(410px,100px,300px,12px,"right",true)
//                               
// Note: When using pixel values be sure to pad total width by 10px
// Still looking for a way to make this cleaner
