Most values where CSS allows percent are capped at 100% in Java CSS.

For example, "width: 200%" and "width: 100%" are equal, which is incorrect.

In Swing, when you load the provided HTML file into JEditorPane, all three <div> elements have the same width, and they fit inside the outer <div>.

When viewed in a browser, the widths of the nested <div> elements are larger except for the last one with 'width: 100%'.

The CSS property 'overflow: visible' is not necessary, it is the default value of the property. If you change to 'overflow: hidden', the browser will render the HTML like Swing does.
