css - 努力应对响应式设计

Question

我正在努力解决一件事。我正在将 psd 编码为 html，但是当我想让我的网站具有响应能力时，我无法用一个 div 解决问题。

.features_items {
  margin: 0 auto;
  display: flex;
  flex: column;
  flex-wrap: wrap;
  justify-content: center;
  align-items: center;
}

.features_item {
  padding: 200px 0 100px 0;
  text-align: center;
  position: relative;
}

.features_items h3 {
  padding-top: 80px;
  color: #f4d320;
}

.features_item_text {
  padding-top: 15px;
  line-height: 200%;
}

.features_items_person {
  background: url(../images/person.png) top 20% center no-repeat;
}

.features_items_cloud {
  background: url(../images/cloud.png) top 20% center no-repeat;
}

.features_items_database {
  background: url(../images/database.png) top 20% center no-repeat;
}

.features_items_monitoring {
  background: url(../images/screen.png) top 20% center no-repeat;
}

.features_items_person:before,
.features_items_cloud:before,
.features_items_database:before,
.features_items_monitoring:before {
  content: "";
  position: absolute;
  border-bottom: 2px solid #8d8d99;
  height: 1px;
  width: 15%;
  top: 48%;
  left: 43%;
}

<div class="features_items">
  <figure class="features_item features_items_person">
    <h3>Live Support</h3>
    <figcaption class="features_item_text">This is Photoshops version of Lorem Ipsum.Proin gravida nibh vel velit auctor aliquet.</figcaption>

总是在同一条车道上？ 如何将它们制作成 2 行 2 列，最大宽度 1024px ？

Answer 1

我建议您更改为row方向，然后使元素换行flex-flow: row wrap;

此外，您还为它们指定至少 35% 的宽度 (flex-basis)，因此一行中不能容纳超过 2 个。

我更新了这 2 条规则，如下所示，它会在较宽的屏幕上为您提供 2 列，在较小的屏幕上为您提供 1 列。
