Here is the appearance of some typical one-column, two-column, three-column, and four‑column themes.
One-column themes just display posts, and sometimes have a sub-menu at the header and the footer; there is no sidebar. Let us take a look at a typical one-column theme. The theme we display here is Off The Wall developed by Sheba Um Malek.
Two-column themes display a column for posts and also a sidebar for displaying other information. For most examples in this chapter, we will use the Almost Spring theme, which is a two-column theme developed by Becca Wei.
