To use the following three macros it is necessary to equire{color} first.
colorbox : box with a background color
colorbox{<color>}{<text>}
colorbox{yellow}{text} $colorbox{yellow}{text}$
colorbox{yellow}{$a^2+b^2=c^2$} $colorbox{yellow}{$a^2+b^2=c^2$}$
Notice that the box is a bit too high when the content is pure text.
fbox : framed box
fbox{text} $fbox{text}$
fbox{$a^2+b^2=c^2$} $fbox{$a^2+b^2=c^2$}$
Again the box is a bit too high when the content is pure text.
fcolorbox: a box with both a frame color and a background color.
fcolorbox{<frame color>}{<background color>}{<text>}
fcolorbox{red}{blue}{text} $fcolorbox{red}{blue}{text}$
fcolorbox{red}{blue}{$a^2+b^2=c^2$} $fcolorbox{red}{blue}{$a^2+b^2=c^2$}$
To use the enclose macro you have to
equire{enclose} first.
enclose{roundedbox}{a^2+b^2 = c^2} $enclose{roundedbox}{a^2+b^2 = c^2}$
