如何在两次网格潜水之间制作图像?那个图像在一个上是50%,在另一个上是50%吗?
<div class="row">
<div class="col-lg-12">
</div>
</div>
<div class="sec-div">
<img class="img-fluid img-second "src="http://lorempixel.com/400/200/cats">
</div>
<div class="row">
<div class="col-lg-12 second">
</div>
</div>

答案 0 :(得分:-1)
我认为您应该使用library(dplyr)
library(tidytext)
library(gutenbergr)
freud_books <- gutenberg_download(c(14969, 15489, 34300, 35875, 35877, 38219, 41214),
meta_fields = "title")
tidy_books <- freud_books %>%
unnest_tokens(word, text)
f_sentiment <- tidy_books %>%
inner_join(get_sentiments("bing"), by = "word") %>%
mutate(line = row_number()) %>%
count(title, index = line %/% 80, sentiment) %>%
spread(sentiment, n, fill = 0) %>%
mutate(sentiment = positive - negative)
来保留z-index
- 不确定是否有必要,设置img
并设置主body { background-color: gray }
margin
1}}具有负值。我认为这会奏效。
试试这个:(我假设你正在使用Bootstrap)
HTML:
div
CSS:
<div class="container-fluid" id="header"></div>
<div class="container second">
<div class="col-lg-12 ">
</div>
</div>
看到它在这里工作! https://jsfiddle.net/hokumi/m7qoy7h3/
