问题描述
想知道你能帮我吗？我试图在Java中创建一些编码，以通过实现 CSS 在 JEditorPane 中执行html代码。 >
我可以通过 CSS 编码来实现 忽略编码中的float：位。在JSFiddle（链接）我得到它运行无瑕疵，但在Java / NB它创建容器，左 div 这是小的，并且应该右边 div ，但它放在左边< c $ c> div ，而不是在它的右边。我想的是，Java和 HTMLEditorKit 以及 StyleSheet 不支持我想做的。
看起来似乎是这样的：
仅支持 HTML 3.2 。是否有可能的解决方法？ import java.awt.Dimension;
import javax.swing。*;
import javax.swing.text.Document;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.StyleSheet;

Wondering if you could help me? I'm trying to create some coding in Java to execute html code in a JEditorPane by implementing CSS.
I get it to implement some of the CSS coding as a rule, but it seems to ignore the "float:" bit in the coding. On JSFiddle (link) I get it to run flawlessly, but on Java/NB it creates the container, left div which is small, and the supposed right div, but it puts it below the left div, instead of to the right of it. What I'm thinking is that Java and HTMLEditorKit as well as StyleSheet doesn't support what I want to do. Can anybody give some clarity on this?
Edit:
It seem that only HTML 3.2 is supported. Is there a possible workaround for this?
import java.awt.Dimension;

解决方案
According to the documentation, Swing components support only HTML 3.2.
And, according to this link, some CSS properties are not rendered:
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-style (only supports inset, outset and none)
- border-top-color
- border-right-color
- border-bottom-color
- border-left-color
- border-color
- list-style-image
- list-style-type
- list-style-position
The following are modeled, but currently not rendered.
- font-variant
- background-attachment (background always treated as scroll)
- word-spacing
- letter-spacing
- text-indent
- text-transform
- line-height
- border-top-width (this is used to indicate if a border should be used)
- border-right-width
- border-bottom-width
- border-left-width
- border-width
- border-top
- border-right
- border-bottom
- border-left
- border
- width
- height
