Rules for a good Knowledge Base logo ****A good Knowledge Base logo should:**** * Be simple, and contain a single line of text * Every component of the logo should hold on the same vertical line (eg. actual logo icon and company name text) * Be much larger in width than in height || As to guarantee the visual structure of your Knowledge Base, we have to put a hard constraint on your logo height.

Customize the logo height with CSS ****If you are unable to come up with a better logo image using Section 1 recommendations, you can still customize the logo height using CSS.**** Crisp Knowledge Base lets you customize the Knowledge Base CSS.
