How to decrease your Blog Title Font, Blogger Page Header Font

From Template, HTML Edit, do a find (use your browser's find feature) for "pagetitlefont", change default=from 270% (mine was) to a smaller number, such a 140%. I have changed all "<" to "(" because blogger thought this was an HTML code and wanted to execute it instead of showing it as text.

(Variable name="pagetitlefont" description="Blog Title Font" type="font" default="normal normal 270% Georgia, Serif"
value="normal normal 270% Georgia, Serif")
