24 // Goal: to produce pages that fit the user's defined look and feel, and
25 // may be more accessible as the current user settings (contrast color
26 // schemes, big font sizes, etc.)
27 // Realization in the CSS2:
28 // http://www.w3.org/TR/REC-CSS2/ui.html#system-colors
29 // We can use colors from user's color theme to mimic plain desktop application.
30 //
31 // Alas, nowadays it not works. Webkit-based browser returns hard-coded values,
32 // with exception of these two:
33 // * ButtonText - text on push buttons.
34 // * CaptionText - text in caption, size box, and scrollbar arrow box.
35 //
36 // When user changes color theme, browser re-draws page, so all input elements
37 // (buttons, checkboxes, radiobuttons, drop-down lists, scrollbars, text inputs)
38 // automagically fits user-defined theme. We need to change web document's
39 // colors manually. We can't ask for exact user defined colors for document's
40 // background in any way, we can only imagine if it dark or light.
41 // So, plan is follows:
42 // We use 'ButtonText' color for base document's color, and calculate if it
43 // dark or light. If color of button's text is dark, then color of button's body
44 // is light, and we define entire web document as light; and vice versa.
45
46 // Get 'ButtonText' color value (as current text's color of body)
47 var body = document.getElementsByTagName('body')[0];
48 var bodyColor = window.getComputedStyle(body, null).color;
49 console.info("Set bodyColor: %s", bodyColor);
50
51 // Returned value must be in format like "rgb(212, 212, 212)" or "rgba(192, 68, 1, 0)"
52 if (bodyColor.indexOf("rgb") != -1) {
53 // Make array with color components
54 var results = bodyColor.match(/^rgba?\((\d{1,3}),\s*(\d{1,3}),\s*(\d{1,3})/);
55
56 // Calculate luminance (brightness) in range 0..1
57 if (results && results.length >= 3) {
58 r = parseInt(results[1], 10);
59 g = parseInt(results[2], 10);
60 b = parseInt(results[3], 10);
61 min = Math.min(r, g, b); max = Math.max(r, g, b);
62 }
63 var luminance = (min + max) / 2 / 255;
64
65 // Set class for body
66 body.classList.add( (luminance > 0.5) ? 'dark' : 'light');
67 }
68 // Now we can use cascade styles for any elements lying on light or dark body:
69 // .light h2 { color: #222; }
70 // .dark h2 { color: #CCC; }
71 // Also we can use semi-transparent colors in some cases:
72 // body footer { color: rgba(128, 128, 128, 0.5); }
