Change post order

Depends on what theme you’re using and how that theme was built.

Some themes MIGHT include an option to change the sort order of the blog but it’s no common.

There are really only 2 ways:

1. Use a plugin like Post Types Order
2. Edit the code to change the way the theme displays posts (requires advanced knowledge)

Something like:

$args = array(
    'orderby' => 'title',
    'order'   => 'ASC',
);
$query = new WP_Query( $args );

Thank you, I found the Post type order and I’m trying it out.

Do you know if there’s a way to change font size on specific words in a post?

CSS is the easiest way:
