如何在调整浏览器窗口大小时防止表格和图像元素移动[REPOST](How to prevent the table and image elements from moving when resizing browser window [REPOST])

我之前发布了一个问题并对其进行了编辑,但编辑后的版本并未显示正确的代码,因此我正在重新发布它。 当我调整我的浏览器窗口大小时,图像似乎走出了“框”或它的容器。 我是编码方面的初学者,我知道如果我使用div而不是table,但是这是为了实践目的(而且我需要它用于学校项目,我想这就是我想如何使用表格元素)。 无论如何,请帮我弄清楚该怎么做/如何修复代码。

编辑:当我调整大小时看起来像这样

.post {
  padding: 3em 3em 1em 3em;
  background: #ffffff;
  border: solid 1px rgba(160, 160, 160, 0.3);
  margin: 0 0 3em 0;
  position: relative;
}

.post>header {
  display: flex;
  border-bottom: solid 1px rgba(160, 160, 160, 0.3);
  left: -3em;
  margin: -3em 0 3em 0;
  position: relative;
  width: calc(100% + 6em);
}

.post>header .title {
  flex-grow: 1;
  flex: 1;
  padding: 3.75em 3em 3.3em 3em;
}

.post>header .title h2 {
  font-weight: 900;
  font-size: 1.5em;
  text-align: center;
}

I previously posted a question and edited it but the edited version does not show the correct code so I'm reposting it. When I resize my browser window, the images seem to go out of the "box" or it's container. I'm a beginner at coding and I know it's much better if I use div instead of table, but this is for practice purposes (and also, I need it for a school project and I figured that's how I want to use the table element). Anyways, please help me figure out what to do/ how to fix the code.

EDIT: Looks like this when I resize.

.post {
  padding: 3em 3em 1em 3em;
  background: #ffffff;
  border: solid 1px rgba(160, 160, 160, 0.3);
  margin: 0 0 3em 0;
  position: relative;
}

.post>header {
  display: flex;
  border-bottom: solid 1px rgba(160, 160, 160, 0.3);
  left: -3em;
  margin: -3em 0 3em 0;
  position: relative;
  width: calc(100% + 6em);
}

.post>header .title {
  flex-grow: 1;

}

.image {
  width: 200px;
  height: 260px;
}

table {
  margin-left: auto;
  margin-right: auto;
}

  padding: 10px;
}

.group {
  margin-left: auto;
  margin-right: auto;
}

天真的做法有多贵?

该条件大约需要1 ns,而* 1000L大约需要3 ns。 所以总共大约4 ns。 如果你每秒这样做2.5亿次,你就会遇到问题。 几千秒我不会担心。

有没有更快的方法处理这个?

我确信这是你在性能方面的问题。 我会使用CPU并测量问题所在而不是猜测。


How expensive is the naive approach?

The condition will take about 1 ns and the * 1000L will take about 3 ns. So about 4 ns in total. If you do this 250 million times per second, you have a problem. A few thousand a second I wouldn't worry about.

Is there any faster way of handling this?

I am sure it is the lease of your problems in terms of performance. I would use a CPU and measure where your problem are instead of guessing.
