Description

Necessity pins a sidebar with your avatar, description, and navigation links alongside the post feed, keeping those elements in view as visitors scroll through the main content, and it automatically drops the sidebar below the feed on phone screens. It works well for anyone who writes long-form posts, mixes post formats, and wants the blog’s identity — name, photo, and links — to stay visible while people read, even on lengthy posts with plenty of scrolling.

How to Download Necessity

Necessity is available for download here on Ultrapack. Installation on Tumblr happens under Settings > Edit Appearance > Edit HTML, where the code from the file replaces the theme currently in use before you save the changes to your blog.

A theme with a fixed sidebar calls for a well-crafted avatar and bio, since those elements stay on display the whole time rather than showing up only at the top of the page. It’s worth reviewing that introductory text before applying the theme, especially if the blog has been around for a while.
