我做了一些事情，但是每次我解决一个问题时，都会出现另外两个问题。我是HTML和CSS的新手，并不真正了解元素应该在什么地方，什么地方以及为什么起作用。

这是HTML和CSS： http://jsfiddle.net/rvgxudt4/

我有一些“理解”问题：

我猜我一直在错误地使用这些类，而且我不知道如何更好地使用它们！ 2.元素不会像原始站点那样居中。
flex-wrap：仅当窗口很小时，自动换行示例：https://s33.postimg.cc/pen7ggevj/Capture.jpg
文本是如此令人讨厌。调整大小时，我无法获得相同的行高；我无法正确调整大小：它总是太大或太小
div不在我希望他们呆的地方！
查看右下角的小消息按钮！无论窗口大小如何，都应该固定他，但请猜测一下：他移动了！！！

请帮助我！我已经为此工作了几天，但我不明白自己在哪里或做错了什么，也找不到符合我需要的教程。我发现的所有教程都是胡说八道！

它应该是这样的： https://media.giphy.com/media/8PySLM55qjM0uWP2B8/giphy.gif

这是它的外观： https://media.giphy.com/media/2tKCZBAUfxIYBWNfjj/giphy.gif

谢谢！

我只研究HTML和CSS。我对JSS或任何其他Java语言一无所知。

您的问题有点'太笼统了，也许您应该开始阅读一些书籍，这些书籍将为您提供完成这些工作的基础。无论如何，我会尝试向您推荐一些可以帮助您的内容：

类名应该是有说服力的，例如容器，部分，包装器，ECC等。我喜欢使用BEM方法来创建可重复使用且直观的东西。 http://getbem.com/
Flexbox刚开始时可能会有些棘手，但过了一段时间后，一切变得简单。我仍然建议您从基础开始（块，内联块，内联，ecc ...），然后再开始。这个YouTube频道可以给您一些建议：https://www.youtube.com/watch?v=G7EIAgfkhmg
这不是最佳做法，但是对于文本，我只喜欢使用“ px”值，请不要忘记每个标记都有其默认值和字体粗细。
如果不确定自己在做什么，Div永远不会呆在你想要的地方：D
不是按钮在移动，而是您的容器根据高度而变小，您应该使用min-height：100vh而不是固定高度100vh，因为这种高度取决于窗口的高度。

原始站点也有此问题，如果您调整窗口高度的大小，则每个部分中的元素都将悬于下一个部分。

我的建议是忘记绝对位置，仅使用flexbox，您可以使用一种可能是这样的布局来完成几乎整个站点的工作：

/* Reset all browsers default values */
* {
  padding: 0;
  margin: 0;
  }
img {
  border:none;
  }

/* Style */

.section {
  align-items: center; /* Vertical center first row of flex element, default value is STRETCH */
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  width: 100%;
  height: auto;
  min-height: calc(100vh - 80px); /* Remove padding 40px top and bottom */
  background-color: #45BB94;
  padding: 40px 0; /* Prevent the content to touch the border of the section when window height is resized */
}
.wrapper {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  width: 100%;
  max-width: 70%;
  background-color: #424242; /* Use background could help you understand what happen to the element */
  margin: 0 auto; /* Horizontal centering div */
}
.img-container {
  display flex;
  flex-direction: row;
  flex-wrap: wrap;
  width: 20%; /* this could be img width */
  min-height: 100%;
  background: lightblue;
}
.logo {
  display: block;
  max-width: 100%;
  height: auto;
  /* This code will transform image to responsive */
}
.text-container {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  width: 80%;
  min-height: 100%;
  background-color: lightcoral;
}

    <div class="section">
        <div class="wrapper">
            <div class="img-container">
                <img class="logo" src="https://plantanapp.com/Portals/_default/Skins/PlantanappLanding/Landing/papp-logo.svg">
            </div>
            <div class="text-container">
               <p>Lorem ipsum dolor sit amet
               Lorem ipsum dolor sit amet
               Lorem ipsum dolor sit amet
               Lorem ipsum dolor sit amet
               </p>
            </div>
        </div><!--wrapper-->
    </div><!--section-->

<!--use comment at the end of an element help you understand what tag is-->

希望对您有所帮助。
