想知道你是否可以帮助我?我正在尝试通过实现 CSS
在 Java 中创建一些代码以在 JEditorPane
中执行 html 代码。
我得到它来实现 一些 CSS
编码作为规则,但它似乎忽略了 "float:"
位编码。在 JSFiddle ( link ) 上,我让它完美运行,但在 Java/NB 上,它创建了容器,左边的 div
很小,右边的 div
,但它把它放在左边 div
的下方,而不是右边。我在想的是 Java 和 HTMLEditorKit
以及 StyleSheet
不支持我想做的事情。任何人都可以澄清一下吗?
编辑:
似乎只支持HTML 3.2
。是否有可能的解决方法?

根据documentation , Swing 组件仅支持 HTML 3.2。
并且,根据这个link , 某些 CSS 属性未呈现:
The following describes the CSS properties that are suppored by the rendering engine:
- font-family
- font-style
- font-size (supports relative units)
- font-weight
- font
- color
- background-color (with the exception of transparent)
- background-image
- background-repeat
- background-position
- background
- text-decoration (with the exception of blink and overline)
- vertical-align (only sup and super)
- text-align (justify is treated as center)
- margin-top
- margin-right
- margin-bottom
- margin-left
- margin
- padding-top
- padding-right
- padding-bottom
- padding-left
- padding
- border-top-style
- border-right-style
- border-bottom-style
- border-left-style

- border-top-color
- border-right-color
- border-bottom-color
- border-left-color
