Found some bugs in SiteOrigin Features Widget:
— “Container shape” not applied on “Icon image”. Border-radius for rounded shape types on img can be used. Or use “Icon image” as backgound.
— “Container size” make size of container in “px”, when “%” selected.
— There is uncontrollable padding:
.sow-features-list .sow-features-feature {padding: 0 25px;}
it move images on 25 px to the left, when size of screen less than total width of all images.
— Always squared container with not squared Icons make them align slighty off center, to the left. Example, first icon “Postal envelope” from Elegant Themes Line Icons Pack.
