How about
怎么样
div[class="sample #{@variable.name}"]
or even
甚至
div class=["sample", @variable.name]
or
或者
.sample *{:class => [@variable1.name, @variable2.name]}
回答by steel
You can use parentheses, curly braces or just a space
您可以使用括号、花括号或仅使用一个空格
.first-class(class="second-class-#{ruby_call}")
.first-class *{class: "second-class-#{ruby_call}"}
.first-class class="second-class-#{ruby_call}"

For slim templates, I've been using the parenthesis notation. You can add additional content on the same line with the equals sign ("="), but be sure to include a space:
对于瘦模板，我一直在使用括号表示法。您可以使用等号 ("=") 在同一行添加其他内容，但一定要包含一个空格：
h1 class=("sample #{@variable.name}") = @variable.to_s
