Buttons
To convert a link into a button, select the link (i.e. first add text and then add a link to the text) and in the editor toolbar go to Format > Custom Formats > btn.
External links will automatically have an icon added that shows they will direct a user outside the website.
To turn a media item link into a button, add the link to the media item, double-click the link, and in the class field, add btn.
Multiple buttons can be added in a line if required; ensure to add spaces between the links.
Centre align buttons using the align centre option on the toolbar.
