FAQ

letter-spacing和word-spacing有什么区别？

letter-spacing控制字符（字母/汉字）之间的间距，影响每个字符之间的距离。word-spacing控制单词之间的间距，只影响空格后的空白距离。两者可以同时使用来精细控制文本排版。

负值的letter-spacing会怎样？

负值会使字符靠得更近，甚至重叠。常用于标题设计创造紧凑的视觉效果。但过小的值（如-2px以下）会严重影响可读性，建议正文和长文本避免使用负值letter-spacing。

letter-spacing的最佳实践是什么？

正文通常使用0-0.05em的小间距；标题和大号文字可使用0.05-0.2em增加优雅感；全大写文字建议增加0.05-0.1em提升可读性；小号文字（如12px以下）建议使用正间距避免文字粘连。移动端和桌面端的合适值可能不同。
