Today I didn't get much done, but I was able to spend some time studying a bit at least.

I really want to make a responsive UI for Rock Paper Scissors because I want to learn and I am a fan of responsive design. I also happened to see [a tweet from Shashi (https://twitter.com/shashiwhocodes/status/1486789899399446535)
regarding using max-width vs width for a responsive web development. I'm hoping to try it out for my UI.

Next, I was feeling a bit uncertain about how I laid out my HTML and CSS so I asked my friend, Dwayne,for some feedback so he suggested using grid after seeing what I had. So this lead me to watching Traversy Media, CSS Grid Layout Crash Course.

CSS Grid Crash Course

Flexbox is 1 dimensional while Grid is 2 dimensional.

"The basic difference between CSS Grid Layout and CSS Flexbox Layout is that flexbox was designed for layout in one dimension - either a row or a column. Grid was designed for two-dimensional layout - rows, and columns at the same time."

Normally for rows and columns, the preferable units to use is fractions, or fr, over percent because of padding and margin.
