Left Sidebar on Blog page Should be collapsible to Improve Reading Experience

[harshita9104]

Describe the bug
The Left sidebar on the blog page takes up unnecessary space and affects readability. Unlike the documentation page, where the sidebar can be minimized by clicking an arrow, the blog page's sidebar remains fixed. This reduces the width available for reading.
To Reproduce
Steps to reproduce the behavior:

1. Go to Blog
2. Observe the left sidebar - it is always visible and cannot be minimized.
3. Scroll through the blog content and notice that it takes up unnecessary space.
4. Compare this behavior with the documentation page, where an arrow button allows the left sidebar to be collapsed.

Expected behavior
The left sidebar should be collapsible, similar to the documentation page.
A small arrow button should allow users to hide/show the sidebar as needed.
When minimized, the blog content should expand to utilize the full screen width for better readability.

Documentation page sidebar is collapsible

** Blogs page doesn't have collapsible sidebar**

Additional context
Implementing a collapsible left sidebar will enhance the reading experience, making it easier to focus on blog content while still accessing navigation when needed.
