Move an inline tikz node vertically to align with baseline of surrounding text

Question

I'm trying to incorporate tikz nodes within running text, but have them align nicely with the text surrounding them. My MWE is:

% !TEX program = xelatex

\documentclass{scrbook}

\usepackage{tikz}

\begin{document}

Some text \tikz \node[rectangle,rounded corners=0.5mm,text=white,fill=black!65,inner sep=2pt] {\scriptsize{}foo}; more text.

\end{document}

This produces:

I would like to shift the node down so that the baseline of "foo" aligns with the baseline of the surrounding text. There's quite a bit of information on aligning relative to other nodes, but really all I need to do is shift it down vertically by a set amount, but I can't figure out how.

What is the easiest/best way for me to shift the entire node down so that baselines align?

Answer 1

Use \tikz[baseline] and anchor=base as an option to the node or use tcolorbox with box align=base

\documentclass{scrbook}

\usepackage[most]{tcolorbox}

\usepackage{tikz}

\begin{document}

Some text \tikz[baseline]{%
\node[rectangle,rounded corners=0.5mm,text=white,fill=black!65,inner sep=2pt,anchor=base] (A) {\scriptsize{}foo};} more text.

Some text \tcbox[enhanced,frame hidden,box align=base,nobeforeafter,left=0pt,right=0pt,top=0pt,bottom=0pt,arc=0.5mm,fontupper=\scriptsize,colupper=white,,colback=black!65]{foo} more text
\end{document}
