By default, geshi-derived syntax highlighters use a serif font to display code blocks.Â Many people find serif fonts less clear than the visually simpler sans-serif fonts.
A good choice is Lucida Console.Â Consolas is even betterÂ because it has a slashed zero, which is easier to distinguish from the capital letter "O", though not as many computers have Consolas installed. To account for this, list the fonts in order of preference, the browser will use the first one that it can display.
To change the default font for code blocks, find the geshi code folder (usually under plugins), open
geshi.php and look for the following code:
1 2 3 4 5
/** * The overall style for this code block * @var string */ var $overall_style = 'font-family:monospace;';
And modify is as seen here. Note that two word font names must be quoted, and the quote marks may need to be escaped, as seen below;
1 2 3 4 5
/** * The overall style for this code block * @var string */ var $overall_style = 'font-family:Consolas, \'Lucida Console\', monospace;';
