1. Stylesheets can't be set anymore on Forms, but only on Solution level
2. Only one stylesheet can be assigned on Solution level
3. Additional stylesheets can be included using the @import statement in the main stylesheet
4. Inherited CSS properties (see http://stackoverflow.com/questions/5612302/which-css-styles-are-inherited) set on a Form will also affect any Forms contained in containers (TabPanel, SplitPane, Accordion etc.) 
5. When different stylesheets are included that utilize the same classnames, the CSS properties set in the classes are merges and incase of duplicates, the last one wins

For checkbox component, in order to horizontal align it from css, we no longer support text-align but have to use justify-content (flexbox system).
