I'll confess: I love blog sidebars! That is probably my favorite design feature of blogs. Every blog of mine has a sidebar, and sometimes, I use two, like at my 100-Word Stories blog and at my class blog (I take my class as a student each semester, so I blog together with the students, doing same assignments they do). Some of the content in my sidebars is static, but most of it is dynamic in some way so that there's something new or different, something "going on" that can catch people's attention and surprise them in the sidebars every time they reload the page.
In this page, I'll provide a quick overview of how sidebars work in Blogger, and then in the following posts I'll zoom in on specific types of sidebar content and how to add them to your blog.
Sidebars and Blogger Themes
As I mentioned in the discussion of Blogger themes and layout, there are basically two generations of Blogger themes. In one set of themes, the sidebar(s) are always visible, and those are the themes I prefer: Simple, Picture Window, Awesome, Watermark, Ethereal, Travel. You can customize those themes to display one, two, or even three sidebars; use the "adjust widths" panel to set the widths of the columns:
In the Blogger themes that use dynamic resizing (Contempo, Soho, Emporio, Notable, Essential), the sidebar column does not appear unless the display is very side; most of the time, you access the sidebar using the hamburger menu at the top of the page. When you click on the menu, the sidebar panel slides out:
Mobile View
I should also mention that all Blogger blogs have an automated mobile-view, and sidebars are suppressed in that mobile view. To see how your blog will look on a phone, just add ?m=1 to any blog or blog post URL. For example:
http://bestlatin.blogspot.com/?m=1
Here's a screenshot:
Sidebars and Blogger Layout
You control the sidebar content and positioning through the Layout option in the Dashboard menu:
If you decide to use Blogger Pages, the Pages menu defaults to that cross-column space, but you can also drag-and-drop the Pages menu down into the sidebar column. I'll have more to say about Blogger Pages later.
Next up, the most important use of the sidebar: blog labels for navigation!
