Hi patrik_hulting,
you could paste the following code into the Custom CSS box on the TwentyXS Settings page:
body, input, textarea, .page-title span, .pingback a.url, h3#comments-title, h3#reply-title, #access .menu, #access div.menu ul, #cancel-comment-reply-link, .form-allowed-tags, #site-info, #site-title, #wp-calendar, .comment-meta, .comment-body tr th, .comment-body thead th, .entry-content label, .entry-content tr th, .entry-content thead th, .entry-meta, .entry-title, .entry-utility, #respond label, .navigation, .page-title, .pingback p, .reply, .widget-title, .wp-caption-text, input[type=submit]
{
font-family: Lucida Handwriting, Georgia, serif;
}
But I don’t recommend you to do this because only a few people will see the actual font “Lucida Handwriting”. (Only people who have this font on their computer will see it correctly.)
Alternatively, you can use the Lucida Handwriting web font: https://www.myfonts.com/fonts/mti/lucida-handwriting/
To use a free web font go to
https://www.google.com/fonts
or
