Clear space is the minimum "breathing room" that must be maintained around a logo to preserve its integrity, ensuring it is always legible and easily identifiable.
Alter or rotate the logo. Manipulate the logo by adding embellishments like drop-shadows, embossing etc.
Its preferable to place the logo on a white background however this is only a suggestion and need not apply in every circumstance.
Its recommended to place the logo in the bottom lefthand corner aligned with the copyright in the righthand corner. A “sticky footer” is worth considering as a digital solution.
