I want to know how can I get the sidebar to display “You might also like:” as displayed in https://www.copyblogger.com/make-wordpress-faster/
I want it to display as at the same location as exactly displayed on copyblogger.
That looks like they’re using javascript to find the height of the page down to the end of the content. Then they’re applying that height to the widget.
The javascript itself is a little too complex for the forums here, but you might have luck over on stackoverflow.com.
