Also updates the test to always scroll the left panel to the top after
opening a section.

Change-Id: Icdb42795b8ec347b91694c162898f41aa8d80152

A new variation named “Light”, similar to iOS7 style.

Fix some valo-menu styles to accommodate the new light style better.

Change-Id: Ib7c396263db7838c972d75a6b79fed1caf7ca576

Mass find-and-replace, tested to work as before in Chrome, and that the
output now includes box -webkit-box-shadow as well as box-shadow.

Bourbon needed to be imported before the css3 utils, so that the
box-shadow mixin can be overridden (Bourbon prints a warning as it has
already deprecated box-shadow prefixes).

Change-Id: I6b4f2047a6d8bfb74f2dbf999d10f7e00005e794

Improve textfied, datefield and combobox mixins so that they can be
used with null parameter values. This makes them output less styles and
allows combining multiple styles together (e.g. small + borderless).

Let valo-button-style mixin support padding as a list instead of just a
single number.

Change default calendar event colors to hex values (Vaadin Sass
compiler doesn’t support all color keywords just yet).

Error styles for date field and combo box

Small fix to table to support all border sizes (Java code has a
hard-coded 1px border width). Remove a few unnecessary selectors.

Make tab sheet tab alignment mixin more generic (now allows both right
and center alignment).

Fix framed tab sheet style border (bottom border caused left and right
borders to have a “cropped” angle at the bottom end).

Fix selection overlay item active style color (i.e. white would produce
a pink color). Now a completely desaturated color won’t be saturated.

Change-Id: I0117e20ef0a597de982a4d0c85a3c78fff87eafc

Add a small API for checkbox, radio button and option group.

Fix border radius for ComboBox (no-text-input + small/large style).

Add better support for form layout section captions (now supports h2,
h3 and h4 labels instead of just h4).

Add “align-right” and “align-center” utility style names for label.

Fix black line artifacts in iOS for panel, window and tabsheet (visible
at certain zoom levels).

Refactor tab sheet styles to be more modular (so you can combine framed
with icons-on-top for instance).

Fix tab sheet loading indicator reserving unnecessary space in parent
layout.

Readonly style for richtextarea.

Fix slider handle focus border color.

Fix #14058: Valo causes Table headers to be overly long
- Table now reserves as little space as necessary
- TreeTable works slightly differently, causing it to reserve more
space in some situations

Rename table mixins to follow naming convention (mixins that do not
output top-level selectors should be suffixed with “-style”, others
not).

Fix TreeTable treespacer style so that it works correctly with row
captions/icons.

Prevent text size adjust on iOS.

Refine default overlay shadow.

Change-Id: I31fa8905c5aa34ab810c3d1c7ac35c3f572c8c04

- Added a new “quiet” style button, and an “icon-align-top” style, and

spinner showing the loading state

- Small fix to slider minimum size

- Fixed TextField text centering for IE8 and IE9

- Fixed Tree expand/collapse arrow clicking in IE10

Change-Id: I48dab61c648363b8eb0c03dc3b3cbbc1289b94ed

one mixin)

more than two colors

- Refactored notifications to use the new position classes as well as
the new animation-in/out functionality

- Refactored overlay styles to use animation-in/out functionality

- Fixed all unwanted white-space and scrollbar issues in all browsers
(font-size:0 or line-height:0 no longer necessary), and fixes vertical
centering in horizontal layout (#13671)

- Fixed borderless menubar clicking bug (Firefox and Opera)

- Fixed table column selector, which no longer produces scrollbars if
placed directly inside a scrollable area in full size

- Fixed table outline overflow in Opera (now using box-shadow instead
in all other browsers except IE8)

- Added toolbar support for windows (header and footer)

- Moved optional notification styles to common-stylenames.scss

-Various other small tweaks

Change-Id: I42343199be12f6d909b9584b7dce3e258846da81

Also fixes #13672 (added ‘notification’ v-included-components list)

Fixes #13746 as well (DragAndDropWrapper won’t hide the drag source any
more)

again and fixed any issues I could find in testing.

Testing done with the following:
Desktop (OS X Mavericks)
-Safari 7

Top level background-color variable, which is then specialized by
different components in the theme.

Mass search-and-replace, tested that the theme works as expected.

Added a new test UI class for the Valo theme.

Updated .gitignore to ignore .sass-cache (command line Sass creates a
cache folder when watching for changes)

Change-Id: I574a393de059aec7b24cb6014d3192d9717688e5

Mass find-and-replace, tested that the theme works as before.
