這是我的代碼片段在HTML的部分。問題在於該部分沒有響應。具體來說，當屏幕變小時，它會水平滾動並顯示空白區域。這是什麼原因？ 我該如何使這部分具有響應性？

你可以讓你的頁面響應你的CSS使用媒體查詢。

這裏是一個教程，讓你開始：

媒體查詢模板從引導：

/* Large desktop */ 
@media (min-width: 1200px) { ... } 

/* Portrait tablet to landscape and desktop */ 
@media (min-width: 768px) and (max-width: 979px) { ... } 

/* Landscape phone to portrait tablet */ 
@media (max-width: 767px) { ... } 

/* Landscape phones and down */ 
@media (max-width: 480px) { ... }
