\fbox fails to inherit color from css

[HenrySeed]

When colouring a Katex rendered field with CSS, it mostly works great, however the \fbox latex tag fails to recolour itself, and stays black.

Is it recommended to instead use some Latex form of colouring?

@HenrySeed Yes, \fbox uses the current LaTeX color. Try e.g. \color{red}\fbox{hi}:

You may want \fcolorbox, which lets you control the frame and background colors. See https://katex.org/docs/support_table.html

@edemaine Cool Ill use the \color tag. Is the coloring via HTML a supported feature or just an unintended side affect?

This is an interesting question. So setting the color using \textcolor from the xcolor package and rendering:

\textcolor{green}{\fbox{a couple of words}}

results in:

This makes me think that if a CSS style updates the color of text it should also update the color \fbox.

@kevinbarabash Agreed, it seems intuitive for \fbox to use the "default color". It also seems to be technically possible, at least for \fbox: current we have a rule

.fbox { border: 0.04em solid black }

but if we replace it with the .fcolorbox rule:

.fcolorbox { border: 0.04em solid }

then the border seems to just inherit the current color (including a default of black).

@ronkok Do you think there would be downsides to this?

No objections here.

Cool, then I put a PR together in #1847.
