Question

我已经使用Google材质图标在按钮中的文本之前添加了“播放”徽标。但是，插入图标后，文本和图标都将略微移出其位置，并且不会保持其中心对齐。如何保持对齐？

.play{
    border: 1px solid black;
    border-radius: 20px;
    padding: 5px 25px;
    text-transform: uppercase;
    margin: 10px;
    background-color: transparent;
    color: black;
}

.play::before{
    font-family: 'Material Icons';
    content: 'play_circle_filled';
    position: relative;
    text-transform: lowercase;
    font-size: 18px;
}

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<div class="container d-flex flex-row justify-content-center buttons" style="font-size: 12px;">
                    
                   
<button type="button" class="play"><span class="playicon"></span>Play into video</button>
                </div>

Answer 1

只需添加align-items-center并同时使按钮d-flex ...

<div class="container d-flex align-items-center justify-content-center buttons">
    <button type="button" class="play d-flex align-items-center"><span class="playicon"></span> Play into video</button>
</div>

注意：您不需要flex-row，因为默认是flex-direction：row。

这是一种更改伪元素的字体大小的方法。

.play::before{
  font-family: 'Material Icons';
  content: 'play_circle_filled';
  position: relative;
  text-transform: lowercase;
  font-size: inherit;
  top:1px;
  left:-4px;
}

不知道它是否对您有用。这只是一个尝试。谢谢。

.play{
  border: 1px solid black;
  border-radius: 20px;
  padding: 5px 25px;
  text-transform: uppercase;
  margin: 10px;
  background-color: transparent;
  color: black;
}

.play::before{
  font-family: 'Material Icons';
  content: 'play_circle_filled';
  position: relative;
  text-transform: lowercase;
  font-size: inherit;
  top:1px;
  left:-4px;
}
