使用flex-basis时Flex项溢出

Question

我想使用flex-basis属性在元素之间创建间隔符。这样做将允许我保持元素之间的空间，而不管“flex-direction`”。

这在使用flex-direction: column时非常有效，但在使用flex-direction: row (默认值)时，行中的最后一项会溢出并被裁剪。

​

完整的工作示例如下：https://codepen.io/anon/pen/NVxaoy

​

input {
  margin: 0;
}

.field {
  display: flex;
}

.field.stacked {
  flex-flow: column;
}

.label {
  display: flex;
}

.spacer.x1 {
  background: green;
  flex: 0 0 8px;
}

.spacer.x2 {
  background: red;
  flex: 0 0 16px;
}

<h1>Horizontal</h1>
<div class="field">
  <label class="label">
            <input type="checkbox">
            <div class="spacer x1"></div>
            <div class="text">Apple</div>
        </label>
  <div class="spacer x2"></div>
  <label class="label">
            <input type="checkbox" />
            <div class="spacer x1"></div>
            <div class="text">Banana</div>
        </label>
  <div class="spacer x2"></div>
  <label class="label">
            <input type="checkbox" />
            <div class="spacer x1"></div>
            <div class="text">Orange</div>
        </label>
</div>
<h1>Stacked</h1>
<div class="field stacked">
  <label class="label">
            <input type="checkbox">
            <div class="spacer x1"></div>
            <div class="text">Apple</div>
        </label>
  <div class="spacer x2"></div>
  <label class="label">
            <input type="checkbox" />
            <div class="spacer x1"></div>
            <div class="text">Banana</div>
        </label>
  <div class="spacer x2"></div>
  <label class="label">
            <input type="checkbox" />
            <div class="spacer x1"></div>
            <div class="text">Orange</div>
        </label>
</div>

对此有解决方案或解决方法吗？

Answer 1

老实说，我不确定为什么会发生这种裁剪，但您可以通过更改间隔符来解决这个问题，使用width而不是flex

​

input { margin: 0 }

.field {
  display: flex;
}

.field.stacked {
  flex-flow: column;
}

.label {
  display: flex;
}

.spacer.x1 {
  background: green;
  width: 8px;
}
.spacer.x2 {
  background: red;
  flex: 0 0 16px;
}

<h1>Horizontal</h1>
<div class="field">
  <label class="label">
    <input type="checkbox">
    <div class="spacer x1"></div>
    <div class="text">Apple</div>
  </label>
  <div class="spacer x2"></div>
  <label class="label">
    <input type="checkbox" />
    <div class="spacer x1"></div>
    <div class="text">Banana</div>
  </label>
  <div class="spacer x2"></div>
  <label class="label">
    <input type="checkbox" />
    <div class="spacer x1"></div>
    <div class="text">Orange</div>
  </label>
</div>

<h1>Stacked</h1>
<div class="field stacked">
  <label class="label">
    <input type="checkbox">
    <div class="spacer x1"></div>
    <div class="text">Apple</div>
  </label>
  <div class="spacer x2"></div>
  <label class="label">
    <input type="checkbox" />
    <div class="spacer x1"></div>
    <div class="text">Banana</div>
  </label>
  <div class="spacer x2"></div>
  <label class="label">
    <input type="checkbox" />
    <div class="spacer x1"></div>
    <div class="text">Orange</div>
  </label>
</div>
