I've managed to dowload and setup Jekyll with `minima` theme to log my daily task updates in my blog. Currently it looks like below

[![enter image description here](https://i.stack.imgur.com/7m0oT.png)](https://i.stack.imgur.com/7m0oT.png)

I wanted to make the editable content full screen, so that I have more space in the page for writing really long blog posts. I located the file `_site/assets/main.css` and trying modifying the container

The content of the file is as below. I'm not an expert at SaaS and styling the pages, but I tried to modify the `.container` attribute to increase the `.padding` and `.margin` to random high values and did a `jekyll build` after that and on still loading the page, it wasn't reflecting the changes made.

SO how do I make this page to make maximum utility of the screen space?
