Blog Feed
Link the blog feed page.
Your Blog Feed is automatically populated with the latest blog entries tagged with a "blog" label.
Make sure that your entries are tagged accordingly.
You will find the link to the blog feed preinstalled in the menu bar.
Should you want to change the displayed name though, or add a link to another label, click the pencil icon in the Pages wigdet and edit the pop-up form.
To change the main container's background color, go to:
Advanced ⟶ Backgrounds ⟶ "Main Body".
