html - 我的 flexbox 容器在 Firefox 中有额外的填充

Question

<分区>

Answer 1

这是因为 Firefox 在 flex 元素中处理最小/最大宽度/高度的方式 changed in version 34响应 Flexbox spec 中的更新:

To provide a more reasonable default minimum size for flex items, this specification introduces a new auto value as the initial value of the min-width and min-height properties defined in CSS 2.1.

要修复它，您需要将 min-height: 0; 添加到您的 #item-list > div 选择器覆盖 Firefox 使用的 auto 默认值:

JSFiddle Example

html, body {
    height: 100%;
}
#wrapper {
    height: 50%;
    background: #EAF9FF;
}
#item-list {
    display: flex;
    flex-direction: column;
    height: 100%;
    background: #B8E8F8;
    width: 476px;
    margin: 0 auto;
    padding: 10px;
}
#item-list > .nav-tabs {
    border: none;
}
#item-list > div {
    display: flex;
    flex: 1;
    flex-direction: column;
    height: 100%;
    max-height: 100%;
    background: #9FD9F0;
    padding: 10px;
    min-height: 0; /* This property is new */
}
.list-group {
    overflow-y: scroll;
    background: #82C8E0;
    padding: 10px;
}

                <li>Some item...</li>
            </ul>
        </div>
    </div>
</div>

我想其他浏览器还没有更新以匹配规范，或者他们已经更新并且也调整了他们的 flexbox 实现来弥补？我不确定。
