html - 为什么我的 svg 不在 div 容器内居中？

问题描述

我有以下代码

.services-container {
    width: 100%;
    height: 300px;
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: column;
}

.services-container svg {
    width: 70px;
  /*margin: 0 auto;
    display: block; */

}

.services-branding {
    width: 300px;
}

.services-branding figcaption {
    text-align: center;
}

.services-branding p {
    text-align: center;

}
  <div class="services-container">
        <figure class="services-branding">
          <svg
            xmlns="http://www.w3.org/2000/svg"
            width="120"
            height="124"
            viewBox="0 0 120 124"
          >
            <g>
              <g>
                <g><path fill="#d84848" d="M120 14H56v66h64L99.844 47z" /></g>
                <g><path fill="#aa1f1f" d="M56 66.75V80l17-11z" /></g>
                <g><path fill="#f57b71" d="M73 69H25L6.656 5H73z" /></g>
                <g>
                  <path
                    fill="#daeaf2"
                    d="M4.436.18a5 5 0 0 1 6.123 3.536l30.54 113.98a5 5 0 0 1-9.658 2.587L.9 6.304A5 5 0 0 1 4.435.18z"
                  />
                </g>
              </g>
            </g>
          </svg>
          <figcaption>branding</figcaption>
          <p>
            Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam
            nonummy nibh.
          </p>
        </figure>
      </div>

我的问题是为什么 svg 不像其他元素一样居中？它仅在我添加到 svg display:block 和 margin: 0 auto 但我不确定这是否是正确的居中方式时才有效。你们能给我解释一下吗？预先感谢！

解决方案

这是因为text-align: center不会将<svg>. 您需要将flexbox属性应用到 的直接父级<svg>，.services-branding如下所示：

.services-container {
  width: 100%;
  height: 300px;
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: column;
}

.services-container svg {
  width: 70px;
}

.services-branding {
  width: 300px;
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column;
}

.services-branding figcaption {
  text-align: center;
}

.services-branding p {
  text-align: center;
}
<div class="services-container">
  <figure class="services-branding">
    <svg xmlns="http://www.w3.org/2000/svg" width="120" height="124" viewBox="0 0 120 124">
      <g>
        <g>
          <g><path fill="#d84848" d="M120 14H56v66h64L99.844 47z" /></g>
          <g><path fill="#aa1f1f" d="M56 66.75V80l17-11z" /></g>
          <g><path fill="#f57b71" d="M73 69H25L6.656 5H73z" /></g>
          <g>
            <path
              fill="#daeaf2"
              d="M4.436.18a5 5 0 0 1 6.123 3.536l30.54 113.98a5 5 0 0 1-9.658 2.587L.9 6.304A5 5 0 0 1 4.435.18z"
            />
          </g>
        </g>
      </g>
    </svg>
    <figcaption>branding</figcaption>
    <p>
      Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh.
    </p>
  </figure>
</div>
