Vaadin + CSS

#note:
The stylename you give to a component is added to the root element of a component (in addition to the original style of the component postfixed with the stylename). So in case of the button the following hierarchy of classes is created:

1.v-button-my-stylename .my-stylename
2    .v-button-wrap
3        .v-button-caption

You can then use the following selector to match different styled buttons:

1.my-stylename .v-button-caption {
2    color: ...
3}

# <div
