# Color box with rounded corners

Here's my MWE:

\documentclass{article}
\usepackage[dvipsnames]{xcolor}
\colorlet{LightLavender}{Lavender!40!}

\begin{document}

\colorbox{LightLavender}{hello} world

\end{document}


It produces something like this:

I'm wondering if it's possible to have the box have rounded corners. Ideally a solution would work in both text and math modes because I sometimes use it in equations to help designate which terms are alike/cancel out.

• mdframed also having better features.... – MadyYuvi Oct 30 at 5:48

tcolorbox, with use in math environment(s):

\documentclass[dvipsnames]{article}
\usepackage[most]{tcolorbox}
\colorlet{LightLavender}{Lavender!40!}
\tcbset{on line,
boxsep=4pt, left=0pt,right=0pt,top=0pt,bottom=0pt,
colframe=white,colback=LightLavender,
highlight math style={enhanced}
}

\begin{document}
\tcbox{Hello} world! $\tcbhighmath{c^2} = a^2 + b^2$
\end{document}


• Very nice...and the boxes are inline with the formula. +1. – Sebastiano Oct 30 at 7:45
• @Sebastiano, thank you very much! – Zarko Oct 30 at 7:56
• Awesome thanks! I didn't know you could add the dvipsnames option to the article class either, so that's an added bonus. – Nate Stemen Oct 30 at 12:56
• @Zarko how would you recommend doing this if I wanted to have multiple color highlights? – Nate Stemen Nov 1 at 21:49
• @NateStemen, this is new question which in comment is not visible well to others, who has similar problems. So it will be nice ask it as such :-). It can be solved on different way, the simplest seems to be add desired color as option to \tcbox or \tcbhighmath. – Zarko Nov 2 at 2:49

Use tcolorbox.

\documentclass{article}
\usepackage[dvipsnames]{xcolor}
\colorlet{LightLavender}{Lavender!40!}
\usepackage{tcolorbox}
\begin{document}

\tcbox[on line,boxsep=0pt,left=2pt,right=2pt,top=2pt,bottom=2pt,colback=LightLavender]{hello} world

\end{document}
