Question

我的页面左侧是可折叠菜单，右侧是一个可以滚动的框（.log-display），但由于某种原因，内容会一直拉伸父容器（.logviewer-container）。当我调整浏览器大小时.logviewer-container应该拉伸以填充浏览器并且永远不会超过窗口大小。

当我用.main-container { display: flex}替换display: block时，问题就消失了，但我正在处理的项目要求使用flex显示容器。

有什么想法吗？

  .html, .body {
    width: 100%;
    height: 100%;
    position: fixed;
  }
    .main-container {
      display: flex;
      max-width: 100%;
      flex-direction: row;
    }

    .menu {
      display: flex;
      flex: 0 0 auto;
      overflow: hidden;
      width: 0;
      -webkit-transition: width 0.5s ease-in-out;
      -moz-transition: width 0.5s ease-in-out;
      -o-transition: width 0.5s ease-in-out;
      transition: width 0.5s ease-in-out;
    }

    .menu.expanded {
      width: 110px;
    }

    .collapser { 
      display: flex;
      align-items: center;
      flex: 0 0 auto;
      width: 10px;
      background-color: gray;
     }

     .collapser p {
      cursor: pointer;
      color: white;
      margin: 0;
     }

    .logviewer-container {
      display: flex;
      flex: 1;
      flex-direction: column;
      border: 1px solid darkgray;
    }

    .toolbar {
      display: flex;
      flex: 0 0 25px;
      background-color: lightblue;
      flex-direction: row;
    }

    .log-display {
      display: flex;
      flex: 1 1 auto;
      overflow: auto;
      flex-direction: column;
    }

    .line {
      flex: 0 0 auto;
      height: 16px;
      font-size: 11px;
      font-family: Monaco, monospace;
    }

    .row-number {
      padding-right: 6px;
      margin-right: 6px;
      width: 50px;
      color: #859900;
      border-right: 1px dotted #859900;
      text-align: end;
    }

    .row-content {
      white-space: pre;
    }

Answer 1

问题是您的元素超出了容器的 width 。您必须确保兄弟元素的width不超过100%。您的三个元素中有两个具有固定的width，因此您需要做的就是将width: calc(100% - 120px) .logviewer-container应用于110px。 10px来自展开的菜单，另一个</head>来自collapser。

另请注意，您错过了结束<代码，并使用了一个小于号（<）的折叠器。您想要使用 calculated width width代替。这些都可以通过 HTML entity 验证您的标记来发现。

我添加了.html, .body { width: 100%; height: 100%; position: fixed; } .main-container { display: flex; max-width: 100%; flex-direction: row; } .menu { display: flex; flex: 0 0 auto; overflow: hidden; width: 0; -webkit-transition: width 0.5s ease-in-out; -moz-transition: width 0.5s ease-in-out; -o-transition: width 0.5s ease-in-out; transition: width 0.5s ease-in-out; } .menu.expanded { width: 110px; } .collapser { display: flex; align-items: center; flex: 0 0 auto; width: 10px; background-color: gray; } .collapser p { cursor: pointer; color: white; margin: 0; } .logviewer-container { display: flex; flex: 1; flex-direction: column; border: 1px solid darkgray; width: calc(100% - 120px); } .toolbar { display: flex; flex: 0 0 25px; background-color: lightblue; flex-direction: row; } .log-display { display: flex; flex: 1 1 auto; overflow: auto; flex-direction: column; } .line { flex: 0 0 auto; height: 16px; font-size: 11px; font-family: Monaco, monospace; } .row-number { padding-right: 6px; margin-right: 6px; width: 50px; color: #859900; border-right: 1px dotted #859900; text-align: end; } .row-content { white-space: pre; }计算并在以下示例中修复了此问题：

width

＆＃13;

请注意，由于.log-display { overflow-y: hidden; }较短，表格现在会添加一个垂直滚动，这会使内容稍微扭曲。您可能希望用以下方式覆盖它：

{{1}}

希望这有帮助！

具有空白空间的Flexbox容器不起作用
