For example, which colour does the b have in &quot; colour yellow colour red (a + colour green b) &quot; , or which size does it have in &quot; size *4 (a + size /2 b) &quot; ? Given a base size of 12, does it have the size 48, 6 or even 24 (which could be seen as a combination)? The following are basic resolution rules, which will be followed consistently in the future. In general, the rules apply to all group operations. This only has a visible effect on the font attributes, like &quot; bold &quot; , &quot; ital &quot; , &quot; phantom &quot; , &quot; size &quot; , &quot; colour &quot; and &quot; font &quot; : Group operations in sequence are treated as if every single operation is enclosed by braces (curly brackets).
这与冲突或相互影响的属性略有不同。这是字体属性通常具有的情况。例如，在 &quot; color yellow color red (a + color green b) &quot; 中，b 是什么颜色，或者在 &quot; size *4 (a + size /2 b) &quot; 中其大小是多少？假设基本大小是 12，则其大小是 48 、6 或者甚至为 24（可将其看作一项组合）？下面是基本的解析规则，以后将始终遵循这些规则。通常，这些规则适用于所有的组合操作。它对于字体属性只具有视觉上的影响，像 &quot; bold &quot; 、 &quot; ital &quot; 、 &quot; phantom &quot; 、 &quot; size &quot; 、 &quot; color &quot; 和 &quot; font &quot; ：
