Table wiggles on value update

[etleyden]

The widest fields in the color picker table are "saturation", "brightness", and "luminosity". When these values change, the entire width of the table changes (since it is some percent of the viewport width), and leads to a wiggly table.

A CSS fix is likely required. Suggestions:

1. find a way to put space between the label and the slider that isn't affected by the width of the label
2. make the label some relative width bigger than the width of the text, but leave it after the css renders?
3. Don't use fixed width.
