Angular Bootstrap中不存在pull-right

Question

我注意到df %>% mutate(col3 = case_when(ID == "ABC" & Date == as.Date("2019-01-03") ~ "fizz", ID == "EFG" & Date == as.Date("2019-01-08") ~ "buzz", TRUE ~ as.character(NA))) # A tibble: 6 x 3 ID Date col3 <chr> <date> <chr> 1 ABC 2019-01-03 fizz 2 EFG 2019-01-08 buzz 3 HIJ 2019-06-09 NA 4 KLM 2019-06-11 NA 5 NOP 2019-08-12 NA 6 QRS 2019-08-21 NA 不能在bootstrap版本中运行，这是正常的吗？还是在该版本中不存在其他CSS类？

Answer 1

在bootstrap 4中已更改为float-right：

<div class="float-right">
  This text is on the right.
</div>
