Consider exploring alternatives to using bootstrap for this specific situation. While bootstrap can be a great tool, it may not always be the best solution for every project. Take some time to sketch out your page layout and determine if a sidebar aligns with the bootstrap grid system. Is it necessary for all content to be contained within a row that spans 100% of the screen height?
It seems like you are looking for a sidebar div with absolute positioning set at 100% screen height. To ensure responsiveness, consider implementing CSS media queries to adjust the layout accordingly.
You can still utilize bootstrap for your content div on the right while customizing it to fit your needs.
