i’m not using the visual editor that much (i like to write css by myself),
but the Border Section is (still?) missing the setting for the border-style. So you have to add the border-style by hand in the code. This is a little bit weird, otherwise the whole border won’t work. Probably the border-style could be a Menu with solid, dotted, double. etc… . And it would be nice if the preset would be „solid“.
The first input of each is for width, the second for color, and the third is for style.
With no style selected it is an “X”. Clicking the X will bring up a menu of the different styles.
Does this help?
Cheers,
Bob
