h1, h2 { margin:0 0 .5em; font:700 2.4em/1 'myriad pro', sans-serif; } h2 { color:#999; margin: 1em 0; font-size:1.6em; }

#wrap { width:500px; margin:1em auto; padding:1.5em; background:#fff; box-shadow:0 1em 2em rgba(0,0,0,.15); }

JavaScript

// Doesn't work as you want
$("input.old").on('focus', function() { $(this).select(); });

// Does what you want
$("input.new").on('mouseup', function() { $(this).select(); });

// You can specify the selector you want ;)
$("#text").on('mouseup', function() { $(this).select(); });
