10 Best Sticky Sidebar Plugins In JavaScript (2025 Update)

When you are running a website or blog, you might need to make a sidebar widget (like featured content, big sales, subscription form, social like box, and ads) stick to the side of your page.

In most cases, you can use CSS position: fixed or position: sticky property to make the whole sidebar stick to the side when the users scroll down or up the webpage:

However, when you only need a block element in the sidebar to be fixed to the side of your page, the situation is a bit more complicated.

You might need JavaScript to keep track of the scroll event and fix a given element to the top while keeping the element stay within the sidebar until it reaches the bottom of the page.

This is why I decide to write this blog post and list here the 10 Best jQuery and Vanilla JavaScript solutions to help beginners quickly implement a sticky sidebar on the webpage.
