How do u change font size in hyperlink code?

i have a hyperlink code that is bold but i dont know how to change the size of the hyperlink or where in the code to put it.Also I have seen some hyperlinks that blink..would also love to know how to do that.How do u change font size in hyperlink code?
%26lt;font size=';10';%26gt;

%26lt;a href=';http://www.google.com';%26gt;Google%26lt;/a%26gt;

%26lt;/font%26gt;.



BTW Blinking anything is bad and annoying... Here's some code, though. Not all browser support it. IE does not but Firefox does.



%26lt;span style=';text-decoration:blink;';%26gt;

%26lt;font size=';10';%26gt;

%26lt;a href=';http://www.google.com';%26gt;Google%26lt;/a%26gt;

%26lt;/font%26gt;

%26lt;/span%26gt;
