<b>我们在行与行之间添加留白的目的是便于读者快速找到下一行。你有没有试过把同一行文字读了两遍，或者不小心跳过一行？那很可能是因为行高太小了。</b> <b>每行文本越宽时，你的视线就需要在横向移动越远，也因此越容易在换行时看错行。</b> <b>所以如果行宽大，那么行高也需要足够大。</b> <img src="https://imagedelivery.net/phxEHgsq3j8gSnfNAJVJSQ/NODE2_4AA35AE3-5953-43F4-B652-B1D3F58327A1/public" style="background-color:initial;max-width:min(100%,1481px);max-height:min(442px);;background-image:url(https://imagedelivery.net/phxEHgsq3j8gSnfNAJVJSQ/NODE2_4AA35AE3-5953-43F4-B652-B1D3F58327A1/public);height:auto;width:100%;object-fit:cover;background-size:cover;display:block;" width="1481" height="442"> <img src="https://imagedelivery.net/phxEHgsq3j8gSnfNAJVJSQ/NODE2_5BE7B632-8D05-4269-874A-8EAED795DE3A/public" style="background-color:initial;max-width:min(100%,1480px);max-height:min(729px);;background-image:url(https://imagedelivery.net/phxEHgsq3j8gSnfNAJVJSQ/NODE2_5BE7B632-8D05-4269-874A-8EAED795DE3A/public);height:auto;width:100%;object-fit:cover;background-size:cover;display:block;" width="1480" height="729">
