• %or% - Select left hand or right hand, e.g.: sel_id('myId') %or% sel_class('myClass') will select both the element with the id and elements with the class. Ideal to select and apply rules multiple elements at once.

• %with% - Left hand selector with right hand selector, e.g.: sel_tag('div') %with% sel_class('aClass') selects a div with a class of aClass. Ideal to narrow down the selection.

Examples

# select all paragraph 'p' with "red" class
sel_tag("p") %with% sel_class("red")

# the other way around works equally well
sel_class("red") %with% sel_tag("p")

# select multiple elements
# where id = "x" or class = "center" 
sel_id("x") %or% sel_class("center")

# select element with id = "x" and parent's id = "y"
sel_id("y") %child% sel_id("y")
