如何将行内的 Flexbox 项目居中？

Question

我试图将行内的列居中，但它们不会居中。我已经尝试多次更改代码，但似乎找不到错误。已经在“服务”和“第 3 节”课程中尝试过justify-content:center，align-items:center但没有成功。我也无法将顶行的“我做什么”文本居中。

现在的样子：

         <div class="what-i-do">

            <h3>WHAT I DO</h3>

          </div>

          <div class="row services">

            <div class="column">

              <div class="first-column">

                <h3 class="services-title">

                  Content <br />

                </h3>

                <div class="services-text">

                  Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

                  Aenean commodo ligula eget dolor. Aenean massa. Cum sociis

                  ridiculus mus. Donec quam felis, ultricies nec, pellentesque

                  eu.

                </div>

              </div>

            </div>

            <div class="column">

              <div class="second-column">

                <h3 class="services-title">

                <div class="services-text">

                  ridiculus mus. Donec quam felis, ultricies nec, pellentesque

                  eu.

                </div>

              </div>

            </div>

Answer 1

在行服务{显示：flex;&nbsp;justify-content（也尝试项目）：center;}很难说一切都去哪里了，但尝试一下。

Answer 2

我在任何地方都没有看到display: flex规则。从这里开始，然后删除列宽，因为它们违背了弹性布局的目的。.row {&nbsp; &nbsp; display: flex;}.column {&nbsp; &nbsp; padding: 0 20px;}.services {&nbsp; &nbsp; align-items: center;&nbsp; &nbsp; justify-content: center;}.services-title {&nbsp; &nbsp; font-family: "Ibarra Real Nova", serif;&nbsp; &nbsp; align-items: center;&nbsp; &nbsp; color: rgba(40, 44, 48, 1);&nbsp; &nbsp; font-weight: bold;&nbsp; &nbsp; text-align: center;&nbsp; &nbsp; font-size: 45px;}.services-text {&nbsp; &nbsp; font-family: "Lato", sans-serif;&nbsp; &nbsp; text-align: justify;&nbsp; &nbsp; line-height: 1.8;&nbsp; &nbsp; letter-spacing: 0em;&nbsp; &nbsp; font-size: 16px;&nbsp; &nbsp; font-weight: 300;}<div class="row services">&nbsp; &nbsp; <div class="column">&nbsp; &nbsp; &nbsp; &nbsp; <div class="first-column">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <h3 class="services-title">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Content <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Creation&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </h3>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="services-text">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Lorem ipsum dolor sit amet, consectetuer adipiscing elit.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Aenean commodo ligula eget dolor.

Answer 3

和align-items:center都justify-items:center在 CSS 网格中工作。您的问题可能与其他 CSS 影响网格的高度/宽度或样式规则display:grid本身的位置有关：html, body{height: 100%}.grid{&nbsp; &nbsp; height: 60%;&nbsp; &nbsp; display: grid;&nbsp; &nbsp; grid-template-columns: 1fr 1fr;&nbsp; &nbsp; background-color: salmon;&nbsp; &nbsp; align-items: center;&nbsp; &nbsp; justify-items: center;}<div class="grid">&nbsp; &nbsp; <div>Lorem ipsum</div>&nbsp; &nbsp; <div>Lorem ipsum lorem ipsum</div></div>
