如何为这些引导面板添加底部边距

Question

在每次面板页脚的迭代之后，我想要一个边距，所以每个帖子都没有连接到最后一个。解决方案不一定是最佳实践，这是一个任何样式都是额外功劳的项目。

ERB：

$ go run go-sqlite3-test.go 
# pkg-config --cflags sqlite3
Package sqlite3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `sqlite3.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sqlite3' found
pkg-config: exit status 1

$ sudo pkg-config --cflags sqlite3 
Package sqlite3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `sqlite3.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sqlite3' found

$ go build 
# pkg-config --cflags sqlite3
Package sqlite3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `sqlite3.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sqlite3' found
pkg-config: exit status 1

Answer 1

嘿不确定你是否想这样做，但你可以用div相同的类名包装每个帖子，并给该类名称设置一个margin-bottom样式：

Answer 2

如果您的示例代码生成HTML <form>元素，则可以使用

为每个元素添加边距

.panel-footer form {
    margin-bottom: 15px;
}
