Web safe Fontshttp://www.w3schools.com/css/css_websafe_fonts.aspWeb-safe fonts are fonts likely to be present on a wide range ofcomputer systems, and used by web content authors toincrease the likelihood that content will be displayed in theirchosen font.If a visitor to a website does not have the specified font, theirbrowser will attempt to select a similar alternative, based on theauthor-specified fallback fonts and generic families.
Why are web fonts this way A technique to download remote fonts was first specified in the CSS2 specification, which introduced the @font- face rule. It was (and remains) controversial because using a remote font as part of a web page allows the font to be freely downloaded. This could result in fonts being used against the terms of their license or illegally spread through the web. TrueDoc (PFR), Embedded OpenType (EOT) and Web Open Font Format (WOFF) are formats designed to address these issues.

WhitespaceWhite space should not be considered merely blank space —it is an important element of design which enables the objectsin it to exist at all, the balance between positive (or non-white)and the use of negative spaces is key to aesthetic composition.When space is at a premium, such as some types of magazine,newspaper, and yellow pages advertising, white space islimited in order to get as much vital information on to the pageas possible. A page crammed full of text or graphics with verylittle white space runs the risk of appearing busy, cluttered, andis typically difficult to read. Some designs compensate for thisproblem through the careful use of leading and typeface.
WhitespaceJudicious use of white space can give a page a classic,elegant, or rich appearance. For example, upscale brands oftenuse ad layouts with little text and a lot of white space. Inexpertuse of white space can make a page appear incomplete.More interesting information about whitespace here:http://www.alistapart.com/articles/whitespaceFind a website with interesting use of whitespace
