al@419 25 // may be more accessible as the current user settings (contrast color
al@419 26 // schemes, big font sizes, etc.)
al@419 27 // Realization in the CSS2:
al@419 28 // http://www.w3.org/TR/REC-CSS2/ui.html#system-colors
al@419 29 // We can use colors from user's color theme to mimic plain desktop application.
al@419 30 //
al@419 31 // Alas, nowadays it not works. Webkit-based browser returns hard-coded values,
al@419 32 // with exception of these two:
al@419 33 // * ButtonText - text on push buttons.
al@419 34 // * CaptionText - text in caption, size box, and scrollbar arrow box.
al@419 35 //
al@419 36 // When user changes color theme, browser re-draws page, so all input elements
al@419 37 // (buttons, checkboxes, radiobuttons, drop-down lists, scrollbars, text inputs)
al@419 38 // automagically fits user-defined theme. We need to change web document's
al@419 39 // colors manually. We can't ask for exact user defined colors for document's
al@419 40 // background in any way, we can only imagine if it dark or light.
al@419 41 // So, plan is follows:
al@419 42 // We use 'ButtonText' color for base document's color, and calculate if it
al@419 43 // dark or light. If color of button's text is dark, then color of button's body
al@419 44 // is light, and we define entire web document as light; and vice versa.
al@419 45
