Book design is the art of incorporating the content, style, format, design, and sequence of the various components of a book into a coherent whole. In the words of Jan Tschichold, "methods and rules upon which it is impossible to improve, have been developed over centuries. To produce perfect books, these rules have to be brought back to life and applied."
Front matter, or preliminaries, is the first section of a book and is usually the smallest section in terms of the number of pages. Each page is counted, but no folio or page number is expressed or printed, on either display pages or blank pages.
 
 
 
 
PINK LAKE
The lake is not always pink in color but the distinctive color of the water changes as a result of green alga Dunaliella salina, halobacterium Halobacteria cutirubrum, and/or high concentration of brine prawn
AURORA
The diffuse aurora is a featureless glow in the sky that may not be visible to the naked eye, even on a dark night. It defines the extent of the auroral zone. The discrete auroras are sharply defined features within the diffuse aurora that vary in brightness from just barely visible to the naked eye, to bright enough to read a newspaper by at night.
