如何使用flexbox CSS连续放置两个项目？

我是flexbox CSS系统的新手，请原谅我缺乏的知识。但是实际上，有了它，我设法解决了一个问题，那就是max-width: 100%;在第二部分中实现了“ ”，当我们在小于600像素的屏幕上时会溢出。

现在我的第一部分看起来很奇怪，SVG缩小了，所有内容都放在了绝对中心。

它应该是这样的：

最后，这是我的代码：

@charset "UTF-8";
@import url("https://fonts.googleapis.com/css2?family=Arvo:wght@400;700&display=swap");
* {
  margin: 0;
}

body {
  width: 100%;
  box-sizing: border-box;
}

:root {
  --body-bg:#fff;
  --body-text:#000000;
  --theme_hero:linear-gradient(45deg, #FF6666, #FF9C75);
  --theme_hero_text:rgba(255, 255, 255, 0.8);
  --theme_hero_subtitle:rgba(255,255,255,0.5);
  --theme_hero_text_desc: rgba(255, 255, 255, 0.3);
  --theme_borders:rgba(190, 196, 211, 0.507);
  --theme_link:rgba(0,0,0,0.5);
  --theme_link-hover:rgba(37, 37, 37, 0.5);
  --theme_footer:#f6fcff;
  --box:#f4f4f4;
  /*! grid */
  --grid-p:rgba(0,0,0,0.5);
  --shadow:rgba(0,0,0,0);
  --content-theme:"";
}

._container {
  max-width: 1280px;
  min-height: 100%;
  margin: 0 auto;
  display: flex;
  flex-direction: row;
  align-items: center;
}

._row {
  display: flex;
  flex-wrap: wrap;
  min-width: 100%;
  flex-direction: row;
  justify-content: space-around;

这是问题的根源：

._container {
    max-width: 1280px;
    min-height: 100%;
    margin: 0 auto;   <------ PROBLEM
    display: flex;
    flex-direction: row;
    align-items: center;
}

通过设置水平自动边距，您将强制弹性项目居中（完整说明）。

同样，它._container是一个flex项目，但auto默认情况下它设置为width，这意味着它将是内容的长度。添加flex: 1以为其提供其父容器的完整宽度。

在中调整图像的高度.n-hero__banner。设置为1024px，因此它将在较小的屏幕上溢出。考虑动态高度值，例如%或vh。
