Well, Blogger finally did it.
In Draft, today, you'll find the new Blogger templates. 3 column templates, templates that use transparency overlays, 4 column templates, even 3 and 4 columns, with split sidebars. And some very shiny backgrounds.
This will keep all the artistic types busy, for a good while. And there will be less damaged templates, from importing third party code.
From the Draft Blogger dashboard, select "Layout". From the navbar, "Customize". Then, "Template Designer".
So that's the end to boring Blogger templates. What you have now is a combinable inventory of 4 exciting styles, with separately selected layouts (2, 3, and 4 columns, split sidebars, left / right variations), a background library with colour palette, and adjustable column widths. Enough choices to keep many bloggers busy choosing.
