Use this section to configure formatting options for Stylus files. When you change these settings, results of a change are displayed in the Preview pane.
Tabs and Indents
Use tab character
An indentation consists of two parts. One part results from nesting code blocks, and the other part is determined by alignment.
In this field, specify the number of spaces that fits in a tab.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted for each indent level.
In this field, specify the number of spaces (or tabs if the Use tab character checkbox is selected) to be inserted between the values of properties.
Keep indents on empty lines
If this checkbox is selected, WebStorm retains indents on empty lines as if they contained some code. If the checkbox is cleared, WebStorm deletes the tab characters and spaces on empty lines.
Use this tab to define where and how many blank lines you want WebStorm to retain and insert in your code after reformatting. The results are displayed in the Preview pane.
Keep Maximum Blank Lines
In this area, specify the number of extra blank lines to be kept after reformatting.
Minimum Blank Lines
In this area, configure whether to have or not to have extra empty lines around top-level blocks and nested selectors. In the field next to each option, specify the minimum number of extra blank lines to be left.
