Designed to use [bootstrap's grid system](http://getbootstrap.com/css/#grid) in Vaadin applications to enable mobile-ready views without writing a single line of CSS. The library is ready to be used by any Vaadin project and requires no widgetset compilation. Usage example: ``` @Viewport("width=device-width, initial-scale=1") // this is necessary public class BootstrapUI extends UI { @Override protected void init(VaadinRequest request) { Container container = new Container(); setContent(container); setSizeFull(); Row row = container.addNewRow(); Col col1 = row.addNewCol(ColMod.SM_6, ColMod.MD_4); Col col2 = row.addNewCol(ColMod.SM_6, ColMod.MD_4, VisibilityMod.HIDDEN_XS); col1.setChildrenStyle(MarginMod.TOP7); col1.addComponent(new TextArea()); col1.addComponent(new TextArea()); col2.addComponent(new Text().append("This ").appendBold("column").append(" will be hidden in ").appendSmall("XS").append(" screens")); col2.addComponent(new HorizontalLayout(new Button("Login", event -> Page.getCurrent().setLocation("/login")), new Button("New User"))); } } ``` `Container` has `Row`(s). `Row` has `Col`(s). `col-*-*`, `col-*-offset-*`, `col-*-push-*`, `col-*-pull-*`, `visible-*`, `hidden-*` styles are available as enum constants. Look for `ColMod`, `ColOffsetMod`, `ColPushPullMod`, `VisibilityMod`, `MarginMod` classes. In the future the library may be extended to support more bootstrap features and components through AbstractJavaScriptComponent. PR's are welcome. Bootstrap version: 3.3.7
