我正在使用 Bootstrap 4 并且正在努力水平和垂直对齐字体真棒图标。我只想使用 Bootstrap 4 内置 CSS，没有自定义 CSS。
我已经设法使用它垂直居中align-self-center但是水平使用justify-content-center似乎不起作用，图标仍然左对齐。
<div class="row">
<div class="col-6">
<h2 class="text-left">Heading 2</h2>
<p class="text-justify">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas accumsan sit amet augue eu suscipit. Maecenas rutrum, mauris nec porta euismod, ligula augue facilisis purus, non ultricies mi nulla lacinia velit. Ut vitae varius odio, vel pharetra nisi. Nam porta, ex eu ornare sollicitudin, erat erat elementum ligula, aliquet commodo.</p>

尝试添加text-center而不是justify-content-center
