當我在我的項目中實現bootstrap時，移動視圖和div的位置移動得很厲害。考慮我的代碼

你需要使用CSS媒體查詢來獲得一個有響應的網站。我建議在網上搜索并閱讀它們，但這可能是一個好的開始:https://CSS-tricks . com/a-complete-guide-to-CSS-media-queries/

但是，這很簡單。基本上，最好的精確方法是設計你的頁面，在你需要的最小屏幕上默認你想要的樣子。然后，隨著屏幕變大，你可以改變一些東西，以便在那些尺寸下工作得更好。

我看到你現在在你的代碼中反其道而行之，你將默認值設置為大屏幕，然后添加媒體查詢，當屏幕變小時，使用@media screen和(max-width: 1100px)覆蓋這些查詢

這里有一個例子:

/*Default styles for small screens*/

html, body {
  padding: 0;
  margin: 0;
}

#container {
  background: #CCC;
  height: 100vh;
  
  width: 100%;
  
}

@media screen and (min-width: 550px){
  /*Styles for screens that are 550px wide or larger*/
  
  #container {
    width: 500px;
    margin: 0 auto;
  }
}

@media screen and (min-width: 768px){
  /*Styles for screens that are 768px wide or larger*/
  
  #container {
    width: 800px;
  }
}

<div id="container"></div>

Bootstrap具有內置的響應樣式類，稱為斷點，使用12列布局來定義事物的外觀。這使您可以更改不同部分在不同屏幕尺寸上的外觀。例如，您可以使用& ltdiv class = & quotcol-12 col-MD-6 col-LG-4 col-XL-3 & quot；& gt...& lt/div & gt；在小屏幕上有一個100%寬度的div，在中等屏幕上有50%寬度的div，等等。

在你開始做真正新奇的事情之前，不需要媒體的詢問；這些實用程序類應該滿足大多數基本需求。

呼應@FiniteLooper的另一個答案，首先為移動屏幕設計你的網站，然后逐步調整到每個斷點，看看你需要調整布局的地方。向上移動要比向下移動容易得多。Pr o提示，iPhone屏幕(標準尺寸，不是plus/xl)是375px寬，所以我使用窗口中的Inspect Element/Developer工具并調整其大小，以便網頁正好是我想要的寬度(見下文):

你可以讓你的頁面有反應，你只需要使用媒體查詢來讓應用程序有反應。媒體查詢是基于顯示內容的設備特征(如屏幕大小、方向和分辨率)應用樣式的CSS規則。通過為不同的設備定義不同的樣式，您可以確保您的應用程序在所有設備上都很好看

我寫了一個例子給你檢查一下:

.container {
  `background-color: rgba(0, 109, 130, 1);`
 

     position: relative;

  

    width: 100%;

    }
    
    .game {
      background-color: #ffffff;
    }
    
    .hintContainer {
      background-color: #ffffff;
      margin-top: 1rem;
    }
    
    @media (min-width: 576px) {
      /* For screens wider than 576px */
      .game {
        margin-left: 20%;
        margin-top: 21%;
        width: 80%;
      }
    
      .hintContainer {
        margin-top: 5rem;
        margin-left: 0;
        padding-left: 2rem;
        width: 30%;
      }
    }
    
    @media (min-width: 992px) {
      /* For screens wider than 992px */
      .game {
        width: 60%;
      }
    
      .hintContainer {
        margin-top: 0;
        margin-left: 5rem;
        padding-left: 5rem;
        width: 35%;
      }
    }
