Static pages or Posts can be created from the admin panel. Just go to Posts > New post to create a content page. You can also add an image to the content.
To edit an existing post, click on Posts to view all the current ones. Then use the Actions > Update option to edit the concerned post.
You can then link different Footer menus or Custom content pages to different posts.
How can I create a footer menu and link it to a static page or an external link?
You can create a footer menu from the New Menu option seen here and edit existing ones from the Menus list.
To edit, click on Actions > Update next to the concerned menu item.
When creating a footer menu, to link to any URL, keep the From system page? Option off and add the URL in the respective field.
On the other hand, to link a menu item to a static page from the site, turn on the From system page? and select the created post from the Page drop-down.
