为什么左边距比使用“geometry”包设置的左边距要大？

我正在设计一本用户手册的封面，尽管使用包将左右边距设置为 1cm geometry，但左边距比要求的大约大 4mm。我运行的代码如下：

下面显示了我使用 gimp 编辑的结果，以清楚地显示我的意思：正如您所见，绿色框内的文本也以接近 6pt 的水平偏移开始。 封面左边距较大

总结一下，我的问题很简单：为什么我在绿色框内的文本上得到更大的左边距和水平偏移？

答案1

TeX 在日志中给出明确的警告，指出标题框不适合该行。

%您在行尾添加了缺失的单词空格，但没有考虑到\fboxsep周围的填充\colorbox。

删除颜色框填充后，您可能至少想要添加一些垂直填充，但左边距现在与左齐平：
