当项目太多时如何解决内容溢出问题以及为什么媒体查询不起作用？

Question

当我尝试媒体查询、Flex 和网格时，我遇到了两个问题。

溢出问题 我在堆栈溢出中搜索相关问题，但没有解决我的问题。当我通过将显示更改为块或减少列来使每个

class =year

部分堆叠在一起时。它不会将下面的内容推到下方，而是仅出现在下一部分的后面。然而，对于投资组合部分，它不存在任何溢出问题。每次媒体查询时，我都必须调整年份部分的边距。有没有更简单的方法来解决这个问题？

媒体查询问题 实验部分再次发生这种情况。当它处于监视器/3800px 大小时，我将 .timeline 宽度更改为 70%。在我这样做之后，当我在屏幕为 2800px 时将 .timeline 宽度更改为 90% 时，它没有改变（参见图 1）。我认为后者应该取代前者？但是，如果我在 3800px 处什么都不做（.year 展开，参见图 4），并且我将 .timeline 2800px 宽度更改为 90%，它就可以工作（参见图 3）。

我还意识到媒体查询的放置很重要。如果我更改下面的部分，如果我在 3800px 之后写 2800px，则会发生相反的情况。这是怎么回事？我该如何解决这个问题？

理想情况下，我希望它在显示器尺寸时看起来像图 2，在 macpro 尺寸时看起来像图 3。

Answer 1

flex

和

flex-wrap

可以避免一些媒体查询，那么网格对于 cards 布局很有用:)。

mediaquerie 也可以减少。

这里有一个例子可以激励您，直到出现更多答案。

.timeline {
  display:flex;
  flex-wrap:wrap;
  gap : 2vw;
  justify-content:center;
}
.year {
  display:grid;
  width:clamp( 280px, 16vw, 400px);
  grid-template-rows: auto auto clamp(50px, 30vmin, 150px) 1fr;
}
.year:nth-child(even) {  
  grid-template-rows: auto auto clamp(30px, 10vmin, 100px) 1fr;  
}
.year::before {
  content:'';
  padding:2px;
  margin:auto;
  grid-row:3;
  display:block;
  height:100%;
}
.time-graphic  {
  margin:auto;
  grid-row:1
}

.date {
  grid-row:2;
  font-size:clamp(26px,4vw ,40px);
  color:white;
  padding:0 1rem;
  /*margin:auto; instead next rule ?*/
  text-align:center;
  border-radius:5px;
}
.time-content {
  grid-row:4;
  border-radius:5px;
  padding:1em;
  margin-bottom:auto;
}


@media (max-width:650px){
  .year {
  grid-template-rows: auto auto 50px 1fr;
}
  .time-content {
  margin-bottom:0;
}
}
