我正在处理一个HTML输出rmd文件。底部的文字是左移，我不知道为什么。output where bottom text is shifted
这是代码底部的一段

`<p>
  <a class="btn btn-primary" data-toggle="collapse" href="#msrpt" role="button" aria-expanded="false" aria-controls="msrpt">
    Base MSRP vs # of EVs (Tesla filtered)
  </a>
</p>
<div class="collapse" id="msrpt">
{r, echo = FALSE}
ev_pop_data_prices_g %>%
  filter(make != "TESLA") %>% 
  filter(n>500)%>%
  ggplot(mapping = aes(x = base_msrp))+ 
  geom_col(mapping = aes(y = n, fill = make))+
  theme(axis.text.x = element_text(angle = 45, vjust = 0.5, hjust=0.5))+
  scale_fill_manual(values = c25)+
  labs(x = "Base MSRP", y = "Number of EVs")
   </div>
</div> 

This is where text is forced left.  `

此外，如果我尝试添加标题，文本根本不会显示在输出中。No text when adding title
