\section{In Running Text}

Without a height the logo stands at 1.25em, where the name beside it is the size of the text: \logo{} in the middle of a sentence, and the sentence runs on as if a word stood there. The icon alone is \logo[icon], the name alone \logo[text].

\section{In Heights}

\logo[height=1cm]

\logo[height=2cm]

\logo[height=3cm]

\section{With the Address}

The line under the logo is as wide as the logo above it, at every height.

\logo[address, height=1cm]

\logo[address, height=2cm]

\section{With the Tagline}

The sentence of the company stands under its name, beside the logo, and the logo is centred on both lines. In running text the logo stays one line: the place asks for the tagline, the company only says what it is.

\logo[tagline, height=1cm]

\logo[tagline, height=2cm]

Both lines together, with the address under them:

\logo[tagline, address, height=2cm]

A face and a colour for the second line are DEVIATIONS a company asks for, one key each. Without them nothing is set for that line and it stands in the colour of the name:

\businessidentity{name face={\bfseries}, tagline color=business-running-quiet}

\logo[tagline, height=2cm]

\section{In Colours}

\logo[color=business-text] \quad \logo[color=business-running-quiet]

\section{Without a Link}

For print: \logo[nolink].
