我试图在列表元素“联系我们”和带有文本“功能和非功能要求”的 h3 元素之间添加边距。但是,我无法做到这一点。看起来 h3 元素以某种方式覆盖了整个列表,因此 margin-top: 10px css 只会在列表上方添加一个边距。有什么建议吗?

The customers should easily be provided a menu for the café. They should also able to make and send in orders for the different events. The website should provide a calendar for all the events. One should be able to click on a date and see happenings
on that day, and also all happenings over a longer periode. For better usability, the customer should be able to divide the different events in smaller groups; concerts, social events or cultural activities and be able to search for events.
The customer should also be able to press a button and get the website in English instead of Norwegian.
