NUglify Missing CSS optimization

Missing CSS optimization - colors

Open SpeednetGroup opened this issue 3 years ago • 2 comments

Please update the CSS optimizations in NUglify to optimize colors.

The shortest methods of including a color in CSS are either with the color name (red, blue, etc.) or with a 6- or 3-digit hex string (#f0f0f0, #e00, etc.).

All CSS colors, except those that include an opacity, should be converted to the shortest color represented either by name or 6- or 3-digit hex string. That would include colors defined by RBG notation (using specific numbers or percentages) and possibly HSL.

RGB is pretty simple to convert to a hex string, which can then be evaluated for possible shrinking to 3-digits or converted to the corresponding name.

Colors that are shorter as hex strings

aliceblue => #f0f8ff antiquewhite => #faebd7 aquamarine => #7fffd4 black => #000 blanchedalmond => #ffebcd blueviolet => #8a2be2 burlywood => #deb887 cadetblue => #5f9ea0 chartreuse => #7fff00 chocolate => #d2691e cornflowerblue => #6495ed cornsilk => #fff8dc darkblue => #00008b darkcyan => #008b8b darkgoldenrod => #b8860b darkgray => #a9a9a9 darkgreen => #006400 darkkhaki => #bdb76b darkmagenta => #8b008b darkolivegreen => #556b2f darkorange => #ff8c00 darkorchid => #9932cc darksalmon => #e9967a darkseagreen => #8fbc8f darkslateblue => #483d8b darkslategray => #2f4f4f darkturquoise => #00ced1 darkviolet => #9400d3 deeppink => #ff1493 deepskyblue => #00bfff dodgerblue => #1e90ff firebrick => #b22222 floralwhite => #fffaf0 forestgreen => #228b22 fuchsia => #f0f gainsboro => #dcdcdc ghostwhite => #f8f8ff greenyellow => #adff2f honeydew => #f0fff0 indianred => #cd5c5c lavenderblush => #fff0f5 lawngreen => #7cfc00 lemonchiffon => #fffacd lightblue => #add8e6 lightcoral => #f08080 lightcyan => #e0ffff lightgoldenrodyellow => #fafad2 lightgreen => #90ee90 lightgrey => #d3d3d3 lightpink => #ffb6c1 lightsalmon => #ffa07a lightseagreen => #20b2aa lightskyblue => #87cefa lightslategray => #789 lightsteelblue => #b0c4de lightyellow => #ffffe0 limegreen => #32cd32 mediumaquamarine => #66cdaa mediumblue => #0000cd mediumorchid => #ba55d3 mediumpurple => #9370db mediumseagreen => #3cb371 mediumslateblue => #7b68ee mediumspringgreen => #00fa9a mediumturquoise => #48d1cc mediumvioletred => #c71585 midnightblue => #191970 mintcream => #f5fffa mistyrose => #ffe4e1 moccasin => #ffe4b5 navajowhite => #ffdead navyblue => #9fafdf olivedrab => #6b8e23 orangered => #ff4500 palegoldenrod => #eee8aa palegreen => #98fb98 paleturquoise => #afeeee palevioletred => #db7093 papayawhip => #ffefd5 peachpuff => #ffdab9 powderblue => #b0e0e6 rosybrown => #bc8f8f royalblue => #4169e1 saddlebrown => #8b4513 sandybrown => #f4a460 seashell => #fff5ee whitesmoke => #f5f5f5 yellowgreen => #9acd32

Colors that are shorter as hex strings, but need to be substituted last because they are partial macthes for other color names

If you've already written this code in your hand rolled version, care to share it to save it being rewritten here

I do have some code that I can rip out, but be warned it is written in VB.NET. The code establishes a static Dictionary that holds color replacement regular expressions (for performance reasons) and then loops through them to check each possible color value.

The other thing I do is to be sure that all colors (both hex and names) are lower-case. There was a study a while back showing a slight performance increase and better network transmission times if you do this.

I'll try to pull out everything relevant from my code and paste below. It might be 12-15 years since I've looked at this code, so no guarantees. It has been in production all that time however.
