0:16Basic set-up: entering a title, subtitle, and About Blurb
1:09Set the color and fixity of the navbar
3:00Set the webpage background color (don’t worry—it will only appear for pages that use the BKG-COLOR background trigger)
3:28Set the “card” color that appears for pages that use the CARD background trigger
4:23Do File > Export > as HTML
5:40The Templates Tab is also your Background Options Control Panel. Click on it and mosey upwards to BlogTopNote (your Home page).
6:18Adding a background trigger for a note changes its background. Here I remove BKG-TEXTURE from the Home page.
6:53Change teaser separation from horizontal rule to floating cards with the CARD background trigger.
7:32Now add the default webpage background color. This time, we use the pop-up menu in the Key Attribute Table.
8:19Now add texture, giving our Home page three triggers at once.
8:57Override the default colors, textures, and images (set in the Styles Dash) with other ones.
9:26The default textures and images are in your Theme Folders (in the Finder).
12:08Appling themes instantly with the Theme Buttons.
13:09To export the theme, just export blog-main.
13:39Each Theme Folder has some extras. To activate these (rather than the defaults) misname a default image by adding a character or two, and then give one of the extras the proper name. This will change your default texture or image.
14:40But you can also override textures and images by referencing other files. Here, we override both default color and default texture.
16:33You can view all background trigger options in the pop-up for $bpBkgOpt. (Run the Keys • BKG stamp first.)
16:45Apply the BKG-FIXED trigger option.
