Guides are non-printing, non-exporting lines that 'float' over your page and assist with the positioning of objects, especially when snapping is enabled. There are two types of guides to aid a variety of designs—ruler and column.
Ruler guides
Ruler guides allow you to add straight horizontal and vertical guide lines to help align content in your document. They can be created and positioned via Guides Settings or by dragging from a ruler.
Column guides
Column guides allow you to specify a number of evenly spaced columns and rows and are perfect for designing page layouts. They can be created and positioned via Guides Settings.
The Column Guides section of Guides Settings allows you to manage the following:
Columns—defines the number of vertical divisions that will appear.
Rows—defines the number of horizontal divisions that will appear.
Gutter—defines the size of the space between column guides.
Style—select from Filled or Outline.
