CSSValue opAssign (float v);
CSSValue opAssign (char[] v);

Allow assignments from ints, floats and strings.

Example:

 CSSValue height;
 height = 3; // width is 3 pixels
 height = "3%"; // width is 3% of parent's height

static CSSValue opCall (float v, bool isPercent = false);
static CSSValue opCall (char[] v);

Constructor for initializing the values

Params:

float v	the value to set
bool isPercent	If precent, v will be based on the Surface parent's value from 0 to 100%

float toPx (lazy float target, bool allow_nan = true);
float toPercent (lazy float target, bool allow_nan = true);

Get the value in terms of pixels or percent, if it's not already a percent value.

float target

If the value is a pixel value, it will be converted to a percentage in terms of this width/height. allow_nan If false , nan's will be converted to 0.
