One way make your website visually interesting to repeat visitors is to create a theme that will, in some way, represent the time of year. A popular on is for the Winter season. Some snow, a little frosting and holly.
Withing the “Edit website” menu is a “Themes” link which allows you to see a list of active themes for your website. The example above shows an already set up theme. The year of the theme will be automatically updated to the next year once the end date has passed.
Clicking the “New Theme” button will allow you to add a new theme. Themes can overlap. By clicking on the link to show the theme details you will both see the button that allows you to add a new style and a table of styles associated to the theme.
