More spacing between elements when application not full screen

When using schedule maker in a responsive mode such as taking up half the screen so that you can look at your notes/classes you want to input on the other half of your screen, the "Show n Results" bar is right on top of the next element. It would be nice to have more spacing to read it easier, but it also makes me think that because it's attached to the next element, it belongs to that class, when it actually is associated with the element above.

在半屏响应式布局中复现 schedule maker，并检查附图中显示的 “Show n Results” 栏。确定周围 UI 的样式并调整间距，使该栏在视觉上与上方元素相关联，且不再与下一个元素重叠；在报告的窗口大小下验证结果。
