Sass is an extension of CSS that allows you to use variables, nested rules and inline imports in stylesheet.

In the highcharts.scss file, there are declared variables which define the most important and popular elements of charts. Use them to easy style the chart in the customs theme. As a result, there is no need to overwrite all CSS classes.
