html - 在 erb 文件中设置虚线内联样式

Question

如何在 erb 文件中设置虚线内联 css 属性。比如这个

<%= image_tag "some_image.png", html: {width: "some_width", height: "some_height", margin:"some_margin"}%>

这工作正常但是当我设置

<%= image_tag "some_image.png", html: {width: "some_width", height: "some_height", margin-left:"some_margin_left"}%>

我明白了

syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('

Answer 1

你有这个错误是因为带有破折号的符号文字(-，比如 :margin-left)不是有效的符号。应该是:

:"margin-left" => "some_margin_left"

此外，此语法应该有效:

margin: {left: "some_margin_left"}
