我尝试使用float:right样式将Add to librarydiv向右对齐，但似乎不起作用。如何将div对齐到Flex右侧。谁能帮忙吗？
null
.song {
display: flex;
flex-direction: row;
border: 1px solid red;
padding: 10px
}
.song-name {
padding: 10px;
display: flex;
align-items: center;
}
.song-action {
padding: 10px;
display: flex;
align-items: center;
color: red;
}<div class="song">
<div class="album-cover">
<img src="https://gravatar.com/avatar/dba6bae8c566f9d4041fb9cd9ada7741?d=identicon&f=y" />
</div>
<div class="song-name">
Song name
</div>
<div class="song-action">
Add to library
</div>
</div>null
只需在要推到边上的元素上使用margin-left：auto即可。在flex容器中，任何一侧带有自动边距的东西都将把它推到最远的另一侧。

只需在添加到库div中添加margin-left:auto即可
