The drawer menu has support icon libraries, like Font Awesome, Material Icons, Open Iconic, IonIcons etc. Icons can also be published as embedded SVG to keep the page weight low.
(this requires WYSIWYG Web Builder 16.1 or newer)
In addition to responsive font-sizes, the column property is also responsive, which means that you can have different number of columns in breakpoints.
