haml 标记中的非法元素错误

Question

我在代码笔中有一段 haml 标记。我不断收到此错误，不知道应该更改什么。

错误消息是："Illegal element: classes and ids must have values."

.hover_box
  %header.hidden

%section.center-column.center-column-title_block.container
  %h1.address_box-title submit your doggo
  %h3.metadata.author by john kazzatspy
  %h4.metadata.date-published april 09

.carousel.ui.container.cards.small
  .card.
    .image
      %img(src="http://via.placeholder.com/50x50")
    .content
      .description fdjsnajfdnsjk fjsanskjfn

%section.center-column.center-column-content
  %textarea.text_input.toSubmit
  %button.ui.button.primary kjkljklj
  .content-container
    %p.content This is a slice of text that I'm serving up to you as a placeholder for all the fabulous content that will be putting in here later.
  %p 
  %p
  %p
  %p

.card-gallery 
%footer

Answer 1

该错误来自您文件中的第 10 行：

.card.

最后的 . 导致 Haml 为这个元素寻找另一个 class，但是有 none.

您可能只需要删除 .:

.card
