After implementing the blockquote class in Bootstrap 4.1.3, all the effects were successfully applied, except for the sidebar.
Here's a comparison of how it appears in tutorials: https://i.sstatic.net/qNXrV.png
And here is how it appears in my Chrome browser: https://i.sstatic.net/YUWSX.png
Despite attempting different browsers, I was unable to resolve the issue using this post.
I am left wondering if this is a problem specific to my computer. Could there be another CSS class conflicting with the sidebar? Your assistance is greatly appreciated.
